The class supports SNMP v1, v2c, and v3. SNMP over DTLS is also supported when [SSLEnabled](#sslenabled-property-ipworkssnmp_snmpmgr-class) is set to True. When acting as a client, the [SSLServerAuthentication](#sslserverauthentication-event-ipworkssnmp_snmpmgr-class) event allows you to check the server identity and other security attributes. The [SSLStatus](#sslstatus-event-ipworkssnmp_snmpmgr-class) event provides information about the DTLS handshake. Additional SSL-related settings are also supported through the [Config](#config-method-ipworkssnmp_snmpmgr-class) method. When acting as a server, the **SSLCert** properties are used to select a certificate for the server. When client authentication is required, the [SSLAuthenticateClients](#sslauthenticateclients-property-ipworkssnmp_snmpmgr-class) property can be set to True and the [SSLClientAuthentication](#sslclientauthentication-event-ipworkssnmp_snmpmgr-class) event can be used to examine client credentials. The class provides both encoding/decoding and transport capabilities, making the task of developing a custom SNMP manager as simple as setting a few key properties and handling a few events. SNMP data, such as for instance SNMP object id-s (OID-s) are exchanged as text strings, thus further simplifying the task of handling them. The class is activated/deactivated by calling the [Activate](#activate-method-ipworkssnmp_snmpmgr-class) or [Deactivate](#deactivate-method-ipworkssnmp_snmpmgr-class) method. These methods enable or disable sending and receiving. The activation status can be found in the [Active](#active-property-ipworkssnmp_snmpmgr-class) property. Messages are received through events such as [Response](#response-event-ipworkssnmp_snmpmgr-class), [Trap](#trap-event-ipworkssnmp_snmpmgr-class), or [InformRequest](#informrequest-event-ipworkssnmp_snmpmgr-class). SNMP Traps are received through the [Trap](#trap-event-ipworkssnmp_snmpmgr-class) event. Messages are sent to other agents or managers by using class's methods such as [SendGetRequest](#sendgetrequest-method-ipworkssnmp_snmpmgr-class), [SendGetNextRequest](#sendgetnextrequest-method-ipworkssnmp_snmpmgr-class), [SendGetBulkRequest](#sendgetbulkrequest-method-ipworkssnmp_snmpmgr-class), [SendSetRequest](#sendsetrequest-method-ipworkssnmp_snmpmgr-class), and [SendInformRequest](#sendinformrequest-method-ipworkssnmp_snmpmgr-class). SNMP OIDs, types, and values are provided in the Objects collection of SNMP objects for both sent and received packets. SNMPv3 USM security is enabled by setting properties such as [User](#user-property-ipworkssnmp_snmpmgr-class), [AuthenticationPassword](#authenticationpassword-property-ipworkssnmp_snmpmgr-class), and [EncryptionPassword](#encryptionpassword-property-ipworkssnmp_snmpmgr-class) and calling the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method to bind to a particular agent ([RemoteEngineId](#remoteengineid-property-ipworkssnmp_snmpmgr-class)). Upon successful discovery, received packets are checked for integrity (authentication) and timeliness. Note that the discovery step is optional, and may be avoided if the values for [RemoteEngineId](#remoteengineid-property-ipworkssnmp_snmpmgr-class), [RemoteEngineBoots](#remoteengineboots-property-ipworkssnmp_snmpmgr-class), and [RemoteEngineTime](#remoteenginetime-property-ipworkssnmp_snmpmgr-class) are known in advance and provided to the class through the respective properties. By default, the class operates synchronously (except for the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method), sending a request and waiting until the corresponding response has been received. This behavior may be overridden by setting [Timeout](#timeout-property-ipworkssnmp_snmpmgr-class) to 0, in which case the class returns control immediately after a send, and responses are received exclusively through the [Response](#response-event-ipworkssnmp_snmpmgr-class) event. ## Property List *The following is the full list of the properties of the class with short descriptions.

This property is read-only and not available at design time. ## Data Type String # ErrorIndex Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Index of the first variable (object) that caused an error from the last SNMP response. ## Object Oriented Interface ```text public function getErrorIndex(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 9 ); ``` ## Default Value 0 ## Remarks This property is used in conjunction with the [ErrorStatus](#errorstatus-property-ipworkssnmp_snmpmgr-class) property, and refers to the object that caused the error reported in the last SNMP response. This value is parsed directly from the SNMP response, which will be a one-based value, so a value of i here maps to index i-1 in the Objects collection. The ErrorIndex property has no meaning when the [ErrorStatus](#errorstatus-property-ipworkssnmp_snmpmgr-class) property is 0 (no error). This property is read-only and not available at design time. ## Data Type Integer # ErrorStatus Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Status code for the last SNMP packet received by the class. ## Object Oriented Interface ```text public function getErrorStatus(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 10 ); ``` ## Default Value 0 ## Remarks This property is used in conjunction with the [ErrorIndex](#errorindex-property-ipworkssnmp_snmpmgr-class) property, which denotes the index of the variable in error. The [ErrorDescription](#errordescription-property-ipworkssnmp_snmpmgr-class) property provides a textual description of the error. The following is a list of valid SNMP status code values: | | | | --- | --- | | 0 (noError) | No error. | | 1 (tooBig) | The response cannot fit in a single SNMP message. | | 2 (noSuchName) | Variable does not exist. | | 3 (badValue) | Invalid value or syntax. | | 4 (readOnly) | Variable is read-only. | | 5 (genError) | Other error (SNMPv1). | | 6 (noAccess) | Access denied. | | 7 (wrongType) | Wrong object type. | | 8 (wrongLength) | Wrong length. | | 9 (wrongEncoding) | Wrong encoding. | | 10 (wrongValue) | Wrong value. | | 11 (noCreation) | No creation. | | 12 (inconsistentValue) | Inconsistent value. | | 13 (resourceUnavailable) | Resource unavailable. | | 14 (commitFailed) | Commit failed. | | 15 (undoFailed) | Undo failed. | | 16 (authorizationError) | Authorization error. | | 17 (notWritable) | Variable is not writable. | | 18 (inconsistentName) | Inconsistent name. | The *ErrorIndex* parameter indicates the index of the first variable (object) that caused an error. The default value is 0. Variable indexes start with 0. *ErrorIndex* has no meaning when *ErrorStatus* is 0 (no error). The default value is 0 (no error). This property is read-only and not available at design time. ## Data Type Integer # LocalEngineId Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The Engine Id of the SNMP Manager. ## Object Oriented Interface ```text public function getLocalEngineId(); public function setLocalEngineId($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 11 ); ipworkssnmp_snmpmgr_set($res, 11, $value ); ``` ## Default Value '' ## Remarks This property is only used for SNMPv3 packets (when [SNMPVersion](#snmpversion-property-ipworkssnmp_snmpmgr-class) is 3). ## Data Type Binary String # LocalHost Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The name of the local host or user-assigned IP interface through which connections are initiated or accepted. ## Object Oriented Interface ```text public function getLocalHost(); public function setLocalHost($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 12 ); ipworkssnmp_snmpmgr_set($res, 12, $value ); ``` ## Default Value '' ## Remarks This property contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address. In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classes) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used. If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface). NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window. ## Data Type String # LocalPort Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The port in the local host where the SNMP Manager is bound to. ## Object Oriented Interface ```text public function getLocalPort(); public function setLocalPort($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 13 ); ipworkssnmp_snmpmgr_set($res, 13, $value ); ``` ## Default Value 0 ## Remarks The LocalPort property must be set before the class is activated ([Active](#active-property-ipworkssnmp_snmpmgr-class) is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine. The default port is 0 (random port). If you would like to receive traps, set LocalPort to 162 (standard trap port). However, it is recommended that the [SNMPTrapMgr](SNMPTrapMgr.md#SNMPTrapMgr) class be used for listening to traps, because [SNMPMgr](#snmpmgr-class) is limited to receiving SNMPv3 traps from a single agent only. [SNMPTrapMgr](SNMPTrapMgr.md#SNMPTrapMgr) does not have this limitation. LocalPort cannot be changed once the class is [Active](#active-property-ipworkssnmp_snmpmgr-class). Any attempt to set the LocalPort property when the class is [Active](#active-property-ipworkssnmp_snmpmgr-class) will generate an error. NOTE: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024. ## Data Type Integer # ObjCount Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The number of records in the Obj arrays. ## Object Oriented Interface ```text public function getObjCount(); public function setObjCount($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 14 ); ipworkssnmp_snmpmgr_set($res, 14, $value ); ``` ## Default Value 0 ## Remarks This property controls the size of the following arrays: - [ObjId](#objid-property-ipworkssnmp_snmpmgr-class) - [ObjType](#objtype-property-ipworkssnmp_snmpmgr-class) - [ObjTypeString](#objtypestring-property-ipworkssnmp_snmpmgr-class) - [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) The array indices start at *0* and end at *ObjCount - 1*. This property is not available at design time. ## Data Type Integer # ObjType Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The current object's type. ## Object Oriented Interface ```text public function getObjType($objindex); public function setObjType($objindex, $value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 15 , $objindex); ipworkssnmp_snmpmgr_set($res, 15, $value , $objindex); ``` ## Possible Values ```text SNMPMGR_OBJTYPE_INTEGER(2), SNMPMGR_OBJTYPE_OCTET_STRING(4), SNMPMGR_OBJTYPE_NULL(5), SNMPMGR_OBJTYPE_OBJECT_ID(6), SNMPMGR_OBJTYPE_IPADDRESS(64), SNMPMGR_OBJTYPE_COUNTER_32(65), SNMPMGR_OBJTYPE_GAUGE_32(66), SNMPMGR_OBJTYPE_TIME_TICKS(67), SNMPMGR_OBJTYPE_OPAQUE(68), SNMPMGR_OBJTYPE_NSAP(69), SNMPMGR_OBJTYPE_COUNTER_64(70), SNMPMGR_OBJTYPE_UNSIGNED_INTEGER_32(71), SNMPMGR_OBJTYPE_NO_SUCH_OBJECT(128), SNMPMGR_OBJTYPE_NO_SUCH_INSTANCE(129), SNMPMGR_OBJTYPE_END_OF_MIB_VIEW(130) ``` ## Default Value 5 ## Remarks The current object's type. The default type is NULL (5). The corresponding object id and value are specified by the [ObjOid](#SNMPMgr_p_ObjOid) and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) properties.

The corresponding object type and value (if any) are specified by the [ObjectType](#SNMPMgr_p_ObjectType) and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) properties. **Example** ```text SNMPControl.ObjCount = 1 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" ``` The *$objindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [ObjCount](#objcount-property-ipworkssnmp_snmpmgr-class) property. This property is not available at design time. ## Data Type String # ObjTypeString Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) A string representation of the current object's ObjectType . ## Object Oriented Interface ```text public function getObjTypeString($objindex); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 17 , $objindex); ``` ## Default Value '' ## Remarks A string representation of the current object's [ObjectType](#SNMPMgr_p_ObjectType). The corresponding object id and value are specified by the [ObjOid](#SNMPMgr_p_ObjOid) and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) properties. The *$objindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [ObjCount](#objcount-property-ipworkssnmp_snmpmgr-class) property. This property is read-only and not available at design time. ## Data Type String # ObjValue Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The current object's value. ## Object Oriented Interface ```text public function getObjValue($objindex); public function setObjValue($objindex, $value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 18 , $objindex); ipworkssnmp_snmpmgr_set($res, 18, $value , $objindex); ``` ## Default Value '' ## Remarks The current object's value. The corresponding object id and type are specified by the [ObjOid](#SNMPMgr_p_ObjOid) and [ObjectType](#SNMPMgr_p_ObjectType) properties. **Example** ```text SNMPControl.ObjCount = 1 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.ObjValue(0) = "New Value" ``` The *$objindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [ObjCount](#objcount-property-ipworkssnmp_snmpmgr-class) property. This property is not available at design time. ## Data Type Binary String # RemoteEngineBoots Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The remote engine boots (SNMPv3). ## Object Oriented Interface ```text public function getRemoteEngineBoots(); public function setRemoteEngineBoots($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 19 ); ipworkssnmp_snmpmgr_set($res, 19, $value ); ``` ## Default Value 0 ## Remarks This property is used in conjunction with the [RemoteEngineTime](#remoteenginetime-property-ipworkssnmp_snmpmgr-class) property. Please refer to the description of the [RemoteEngineTime](#remoteenginetime-property-ipworkssnmp_snmpmgr-class) property, and the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method for further information. ## Data Type Integer # RemoteEngineId Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The Engine Id of the remote agent. ## Object Oriented Interface ```text public function getRemoteEngineId(); public function setRemoteEngineId($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 20 ); ipworkssnmp_snmpmgr_set($res, 20, $value ); ``` ## Default Value '' ## Remarks This property is only used for SNMPv3 packets (see [SNMPVersion](#snmpversion-property-ipworkssnmp_snmpmgr-class)), and is reset every time [RemoteHost](#remotehost-property-ipworkssnmp_snmpmgr-class) or [RemotePort](#remoteport-property-ipworkssnmp_snmpmgr-class) changes. RemoteEngineId is normally discovered through the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method. However, by manually supplying a value for the property, RemoteEngineId discovery step may be eliminated, thus avoiding the extra roundtrip to the agent ([RemoteEngineBoots](#remoteengineboots-property-ipworkssnmp_snmpmgr-class) and [RemoteEngineTime](#remoteenginetime-property-ipworkssnmp_snmpmgr-class) are also required for [User](#user-property-ipworkssnmp_snmpmgr-class) authentication - please refer to the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method for more information). ## Data Type Binary String # RemoteEngineTime Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The remote engine time (SNMPv3). ## Object Oriented Interface ```text public function getRemoteEngineTime(); public function setRemoteEngineTime($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 21 ); ipworkssnmp_snmpmgr_set($res, 21, $value ); ``` ## Default Value 0 ## Remarks RemoteEngineTime is used by SNMPv3 authentication to ensure timeliness of requests, and avoid replay attacks. The value of RemoteEngineTime is provided as what is expected to be the current value of the remote engine clock based on a cached time differential between the remote engine clock and the local engine time obtained during the discovery process (see [Discover](#discover-method-ipworkssnmp_snmpmgr-class)). This property is used in conjunction with [RemoteEngineBoots](#remoteengineboots-property-ipworkssnmp_snmpmgr-class). Please refer to the [RemoteEngineBoots](#remoteengineboots-property-ipworkssnmp_snmpmgr-class) property and the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method for more information. ## Data Type Integer # RemoteHost Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The address of the remote host.

The [SSLServerCertStore](#sslservercertstore-property-ipworkssnmp_snmpmgr-class) and [SSLServerCertSubject](#sslservercertsubject-property-ipworkssnmp_snmpmgr-class) properties also may be used to specify a certificate. When [SSLServerCertEncoded](#sslservercertencoded-property-ipworkssnmp_snmpmgr-class) is set, a search is initiated in the current [SSLServerCertStore](#sslservercertstore-property-ipworkssnmp_snmpmgr-class) for the private key of the certificate. If the key is found, [SSLServerCertSubject](#sslservercertsubject-property-ipworkssnmp_snmpmgr-class) is updated to reflect the full subject of the selected certificate; otherwise, [SSLServerCertSubject](#sslservercertsubject-property-ipworkssnmp_snmpmgr-class) is set to an empty string. This property is read-only and not available at design time. ## Data Type Binary String # StoreWalkObjects Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Tells the class whether or not to store returned objects. ## Object Oriented Interface ```text public function getStoreWalkObjects(); public function setStoreWalkObjects($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 109 ); ipworkssnmp_snmpmgr_set($res, 109, $value ); ``` ## Default Value true ## Remarks When a [Walk](#walk-method-ipworkssnmp_snmpmgr-class) is performed, this property tells the class whether or not to store the objects that are returned by the server in the Objects collection. If the data is accumulated through the events, and not desired to be saved by the class, set this property to false. ## Data Type Boolean # Timeout Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) This property includes the timeout for the class. ## Object Oriented Interface ```text public function getTimeout(); public function setTimeout($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 110 ); ipworkssnmp_snmpmgr_set($res, 110, $value ); ``` ## Default Value 60 ## Remarks If the Timeout property is set to 0, all operations return immediately, potentially failing with a *WOULDBLOCK* error if data cannot be sent immediately. If Timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential *WOULDBLOCK* errors internally and automatically retry the operation for a maximum of Timeout seconds. The class will use [DoEvents](#doevents-method-ipworkssnmp_snmpmgr-class) to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive. If Timeout expires, and the operation is not yet complete, the class fails with an error. NOTE: By default, all timeouts are *inactivity timeouts*, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received. The default value for the Timeout property is 60 seconds. ## Data Type Integer # User Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The user name used for SNMPv3 authentication. ## Object Oriented Interface ```text public function getUser(); public function setUser($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 111 ); ipworkssnmp_snmpmgr_set($res, 111, $value ); ``` ## Default Value '' ## Remarks If authentication is desired, this property must be set before the class attempts to connect to an SNMPv3 Agent. ## Data Type String # WalkLimit Property ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) The limit of oid's returned in a walk. ## Object Oriented Interface ```text public function getWalkLimit(); public function setWalkLimit($value); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_get($res, 112 ); ipworkssnmp_snmpmgr_set($res, 112, $value ); ``` ## Default Value 0 ## Remarks This property specifies the limit of how many oid's are to be traversed during an SNMP [Walk](#walk-method-ipworkssnmp_snmpmgr-class). If set to 0, the class will traverse all oid's in the specified table that are lexicographically greater than the value of the specified table oid. ## Data Type Integer # Activate Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Activates the class. ## Object Oriented Interface ```text public function doActivate(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_activate($res); ``` ## Remarks This method activates the component and will allow it to send or receive data. The class will be automatically activated if it is not already and you attempt to perform an operation which requires the class to be active. NOTE: Use the [Active](#active-property-ipworkssnmp_snmpmgr-class) property to check whether the component is active. # Config Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Sets or retrieves a configuration setting. ## Object Oriented Interface ```text public function doConfig($configurationstring); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_config($res, $configurationstring); ``` ## Remarks Config is a generic method available in every class. It is used to set and retrieve [configuration settings](#config-settings-snmpmgr-class) for the class. These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the Config method. To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter). To read (query) the value of a [configuration setting](#config-settings-snmpmgr-class), you must call *Config("PROPERTY")*. The value will be returned as a string. # Deactivate Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Deactivates the class. ## Object Oriented Interface ```text public function doDeactivate(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_deactivate($res); ``` ## Remarks This method deactivates the component and will prohibit it from sending and receiving data. NOTE: Use the [Active](#active-property-ipworkssnmp_snmpmgr-class) property to check whether the component is active. # Discover Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Performs SNMPv3 discovery. ## Object Oriented Interface ```text public function doDiscover(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_discover($res); ``` ## Remarks When the method is called an SNMPv3 engine discovery request is sent to [RemoteHost](#remotehost-property-ipworkssnmp_snmpmgr-class). If an [AuthenticationPassword](#authenticationpassword-property-ipworkssnmp_snmpmgr-class) is provided, the engine id discovery request is followed by an engine time discovery request, as required by the SNMPv3 User Security Model (USM). In this case [Timeout](#timeout-property-ipworkssnmp_snmpmgr-class) must be set to a non-zero value before calling **Discover** and the class will wait until a response is received from [RemoteHost](#remotehost-property-ipworkssnmp_snmpmgr-class). The [DiscoveryResponse](#discoveryresponse-event-ipworkssnmp_snmpmgr-class) event is fired upon receipt of a valid discovery response and the values of [RemoteEngineId](#remoteengineid-property-ipworkssnmp_snmpmgr-class), [RemoteEngineBoots](#remoteengineboots-property-ipworkssnmp_snmpmgr-class), and [RemoteEngineTime](#remoteenginetime-property-ipworkssnmp_snmpmgr-class) will then be updated with the received Engine Id, Time, and Boots. # DoEvents Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) This method processes events from the internal message queue. ## Object Oriented Interface ```text public function doEvents(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_doevents($res); ``` ## Remarks When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns. # HashPasswords Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Hashes all passwords in the cache. ## Object Oriented Interface ```text public function doHashPasswords(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_hashpasswords($res); ``` ## Remarks Forces computation of all passwords hashes in the cache. Used together with the [HashPassword](#hashpassword-event-ipworkssnmp_snmpmgr-class) event to enable implementations of external password hash storage. # Interrupt Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) This method interrupts the current method. ## Object Oriented Interface ```text public function doInterrupt(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_interrupt($res); ``` ## Remarks If there is no method in progress, Interrupt simply returns, doing nothing. # PauseData Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) This method pauses data reception. ## Object Oriented Interface ```text public function doPauseData(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_pausedata($res); ``` ## Remarks This method pauses data reception when called. While data reception is paused, the DataIn event will not fire. Call [ProcessData](#processdata-method-ipworkssnmp_snmpmgr-class) to reenable data reception. # ProcessData Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) This method reenables data reception after a call to PauseData . ## Object Oriented Interface ```text public function doProcessData(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_processdata($res); ``` ## Remarks This method reenables data reception after a previous call to [PauseData](#pausedata-method-ipworkssnmp_snmpmgr-class). When [PauseData](#pausedata-method-ipworkssnmp_snmpmgr-class) is called, the DataIn event will not fire. To reenable data reception and allow DataIn to fire, call this method. NOTE: This method is used only after previously calling [PauseData](#pausedata-method-ipworkssnmp_snmpmgr-class). It does not need to be called to process incoming data by default. # Reset Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Clears the object arrays. ## Object Oriented Interface ```text public function doReset(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_reset($res); ``` ## Remarks Clears the object arrays, and sets the trap and error properties to their default values. This is useful for reinitializing all the properties that are used to create outgoing packets before building a new packet. Note: [SNMPVersion](#snmpversion-property-ipworkssnmp_snmpmgr-class) will be reset to **snmpverV2c (2)**. # SendGetBulkRequest Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Send a GetBulkRequest packet. ## Object Oriented Interface ```text public function doSendGetBulkRequest($nonrepeaters, $maxrepetitions); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_sendgetbulkrequest($res, $nonrepeaters, $maxrepetitions); ``` ## Remarks Sends a GetBulkRequest packet. This is only available for SNMP versions 2 and 3. *NonRepeaters* specifies the number of variables for which a single lexicographic successor is to be returned. *MaxRepetitions* specifies the number of lexicographic successors to be returned for variables other than those in the *NonRepeaters* list. The object identifiers, types, and values for the request are taken from the Objects collection. A GetBulkRequest is very similar to a GetNextRequest, the difference is that Getbulk performs a continuous GetNext operation based on the *MaxRepetitions* value. The *NonRepeaters* value will determine the number of Objects for which a simple GetNext operation should be performed. For the remaining variables, a continuous GetNext operation is performed based on the *MaxRepetitions* value. So if you send a request containing X objects, the agent will perform N simple GetNext operations and M continuous GetNext operations X - N times. With X being the number of objects received, N being the number of *NonRepeaters*, and M being the number of *MaxRepetitions*. Thus the SNMPMgr is expecting to receive N + M x (X - N) objects, assuming that each object has M successors. **Example (Sending a GetBulk Request)** ```text SNMPControl.RemoteHost = "MyAgent" SNMPControl.ObjCount = 2 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.objId(1) = "1.3.6.1.2.1.1.3.0" SNMPControl.SendGetBulkRequest(1,4) ``` The code sample above will send a GetBulkRequest with 1 non repeater, and a maxrepetitions of 4. Since there is only 1 non repeater, only one ObjID will "not repeat" and will only return one successor. The rest of the ObjID's (in this case, only 1) will return 4 successors. This particular example will return the following ObjID's: | | | | --- | --- | | 1 | 1.3.6.1.2.1.1.2.0 | | 2 | 1.3.6.1.2.1.1.4.0 | | 3 | 1.3.6.1.2.1.1.5.0 | | 4 | 1.3.6.1.2.1.1.6.0 | | 5 | 1.3.6.1.2.1.1.7.0 | # SendGetNextRequest Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Send GetNextRequest packet. ## Object Oriented Interface ```text public function doSendGetNextRequest(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_sendgetnextrequest($res); ``` ## Remarks Sends a GetNextRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection. **Example (Sending a GetNext Request)** ```text SNMPControl.ObjCount = 2 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.SendGetNextRequest() ``` The agent will respond with the "next" (relative to the ObjID(s) you specify) OID in the table. # SendGetRequest Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Send GetRequest packet. ## Object Oriented Interface ```text public function doSendGetRequest(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_sendgetrequest($res); ``` ## Remarks Sends a GetRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection. **Example (Sending a GetRequest)** ```text SNMPControl.RemoteHost = "MyAgent" SNMPControl.ObjCount = 2 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.ObjId(1) = "1.3.6.1.2.1.1.2.0" SNMPControl.SendGetRequest() ``` # SendInformRequest Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Send an InformRequest packet. ## Object Oriented Interface ```text public function doSendInformRequest(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_sendinformrequest($res); ``` ## Remarks Sends an InformRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection. # SendSetRequest Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Send Set Request packet. ## Object Oriented Interface ```text public function doSendSetRequest(); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_sendsetrequest($res); ``` ## Remarks Sends a SetRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection. **Example (Sending a SetRequest)** ```text SNMPControl.RemoteHost = "MyAgent" SNMPControl.ObjCount = 1 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.ObjValue(0) = "New Value" SNMPControl.ObjType(0) = otOctetString SNMPControl.SendSetRequest() ``` # Value Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Returns the value corresponding to an OID. ## Object Oriented Interface ```text public function doValue($oid); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_value($res, $oid); ``` ## Remarks If the OID does not exist in the Objects collection, a trappable error is generated. Please refer to the SNMPObject type for more information. # Walk Method ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Does an SNMP walk starting with the specified oid. ## Object Oriented Interface ```text public function doWalk($tableoid); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_do_walk($res, $tableoid); ``` ## Remarks A walk will traverse all OIDs in the *TableOid* that are lexicographically greater than the value of the *TableOid*. The results of the walk may be obtained through the Response events. During the event, the current returned object will exist inside of the Objects collection. If [StoreWalkObjects](#storewalkobjects-property-ipworkssnmp_snmpmgr-class) is set to true, the Objects collection will contain all returned objects when the Walk completes. Use the [WalkLimit](#walklimit-property-ipworkssnmp_snmpmgr-class) property to regulate how many objects the walk will traverse in the table. NOTE: The collection of objects is cleared before the walk begins. # BadPacket Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired for erroneous and/or malformed messages. ## Object Oriented Interface ```text public function fireBadPacket($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 1, array($this, 'fireBadPacket')); ``` ## Parameter List ```text 'packet' 'sourceaddress' 'sourceport' 'errorcode' 'errordescription' 'report' ``` ## Remarks The full message is provided in the *Packet* parameter. The BadPacket event is also fired when authentication fails for received packets due to a bad password or other reasons. If the *Report* parameter is set to True, an unauthenticated error report will be sent to the client, otherwise the packet will be silently ignored. # Connected Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired immediately after a connection completes (or fails). ## Object Oriented Interface ```text public function fireConnected($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 2, array($this, 'fireConnected')); ``` ## Parameter List ```text 'remoteaddress' 'remoteport' 'statuscode' 'description' ``` ## Remarks This event fires after a connection completes or fails. *StatusCode* is the value returned by the system TCP/IP stack. This will be 0 if the connection was successful. *Description* contains a human readable description of the status. This will be "OK" if the connection was successful. *RemoteAddress* is the IP address of the remote host. *RemotePort* is the port on the remote host. # Disconnected Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when a connection is closed. ## Object Oriented Interface ```text public function fireDisconnected($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 3, array($this, 'fireDisconnected')); ``` ## Parameter List ```text 'remoteaddress' 'remoteport' 'statuscode' 'description' ``` ## Remarks This event fires after a connection is broken. *StatusCode* is the value returned by the system TCP/IP stack. This will be 0 if the connection was broken normally. *Description* contains a human readable description of the status. This will be "OK" if the connection was broken normally. *RemoteAddress* is the IP address of the remote host. *RemotePort* is the port on the remote host. # DiscoveryRequest Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when an SNMPv3 discovery packet is received. ## Object Oriented Interface ```text public function fireDiscoveryRequest($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 4, array($this, 'fireDiscoveryRequest')); ``` ## Parameter List ```text 'engineid' 'engineboots' 'enginetime' 'user' 'securitylevel' 'sourceaddress' 'sourceport' 'respond' ``` ## Remarks *EngineId*, *EngineBoots*, *EngineTime*, and *User* are the values received from *SourceAddress*. For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. *Respond* is True by default, and will automatically send a response using the value in [LocalEngineId](#localengineid-property-ipworkssnmp_snmpmgr-class). To suppress the response, set *Respond* to False. The value returned to *SourceAddress* for *EngineBoots* is always 0, and *EngineTime* is the number of seconds since January 1st, 1970 (GMT). # DiscoveryResponse Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when an SNMPv3 discovery response is received. ## Object Oriented Interface ```text public function fireDiscoveryResponse($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 5, array($this, 'fireDiscoveryResponse')); ``` ## Parameter List ```text 'engineid' 'engineboots' 'enginetime' 'user' 'securitylevel' 'sourceaddress' 'sourceport' ``` ## Remarks *EngineId*, *EngineBoots*, *EngineTime*, and *User* are the values received from *SourceAddress* and *SourcePort*. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated request, *SecurityLevel* is at least 1. # Error Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when information is available about errors during data delivery. ## Object Oriented Interface ```text public function fireError($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 6, array($this, 'fireError')); ``` ## Parameter List ```text 'errorcode' 'description' ``` ## Remarks The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error. The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-snmpmgr-class) section. # HashPassword Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired before and after a password is hashed. ## Object Oriented Interface ```text public function fireHashPassword($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 7, array($this, 'fireHashPassword')); ``` ## Parameter List ```text 'password' 'authalgorithm' 'hash' ``` ## Remarks SNMPv3 passwords are hashed in order to obtain authentication and encryption keys. This is an expensive operation, and in certain situations it may be preferable to store the hashed passwords externally and supply them on demand. If a hash is required, the event fires with an empty string in the *Hash* parameter. In this case, you can choose to supply a value for the hash and stop the class from computing the hash. The event also fires every time a hash is computed. In this case, the *Hash* parameter contains the value of the computed hash. *AuthAlgorithm* contains either 1 for HMAC-MD5-96, 2 for HMAC-SHA-96 or 3 for HMAC-192-SHA-256 # InformRequest Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when an InformRequest packet is received. ## Object Oriented Interface ```text public function fireInformRequest($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 8, array($this, 'fireInformRequest')); ``` ## Parameter List ```text 'requestid' 'snmpversion' 'community' 'user' 'securitylevel' 'sourceaddress' 'sourceport' 'errorindex' 'errorstatus' 'errordescription' 'respond' ``` ## Remarks The user in an InformRequest packet (SNMPv3) must match the user in the [User](#user-property-ipworkssnmp_snmpmgr-class) property. If not, the request is rejected, and a [BadPacket](#badpacket-event-ipworkssnmp_snmpmgr-class) event is fired before InformRequest is fired. The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the [ObjId](#objid-property-ipworkssnmp_snmpmgr-class), [ObjType](#objtype-property-ipworkssnmp_snmpmgr-class), and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. The *MessageId* parameter identifies the received request. For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. To send a response, the *Respond* parameter must be set to true. By default, this value is false, which means no response will be sent. The *ErrorStatus* parameter may also be set to a valid SNMP status code (the default value is 0, which represents no error). The following is a list of valid SNMP status code values: | | | | --- | --- | | 0 (noError) | No error. | | 1 (tooBig) | The response cannot fit in a single SNMP message. | | 2 (noSuchName) | Variable does not exist. | | 3 (badValue) | Invalid value or syntax. | | 4 (readOnly) | Variable is read-only. | | 5 (genError) | Other error (SNMPv1). | | 6 (noAccess) | Access denied. | | 7 (wrongType) | Wrong object type. | | 8 (wrongLength) | Wrong length. | | 9 (wrongEncoding) | Wrong encoding. | | 10 (wrongValue) | Wrong value. | | 11 (noCreation) | No creation. | | 12 (inconsistentValue) | Inconsistent value. | | 13 (resourceUnavailable) | Resource unavailable. | | 14 (commitFailed) | Commit failed. | | 15 (undoFailed) | Undo failed. | | 16 (authorizationError) | Authorization error. | | 17 (notWritable) | Variable is not writable. | | 18 (inconsistentName) | Inconsistent name. | The *ErrorIndex* parameter indicates the index of the first variable (object) that caused an error. The default value is 0. Variable indexes start with 0. *ErrorIndex* has no meaning when *ErrorStatus* is 0 (no error). # PacketTrace Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired for every packet sent or received. ## Object Oriented Interface ```text public function firePacketTrace($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 9, array($this, 'firePacketTrace')); ``` ## Parameter List ```text 'packet' 'direction' 'packetaddress' 'packetport' ``` ## Remarks The PacketTrace event shows all the packets sent or received by the class. *Packet* contains the full contents of the datagram. *Direction* shows the direction of the packet: 1 for incoming packets, and 2 for outgoing packets. In the case of an incoming packet, *PacketAddress* and *PacketPort* identify the source of the packet. In the case of an outgoing packet, *PacketAddress* and *PacketPort* identify the destination of the packet. # ReadyToSend Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when the class is ready to send data. ## Object Oriented Interface ```text public function fireReadyToSend($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 10, array($this, 'fireReadyToSend')); ``` ## Parameter List ```text ``` ## Remarks The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend(TBD. DataToSend is removed). # Report Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when a Report packet is received. ## Object Oriented Interface ```text public function fireReport($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 11, array($this, 'fireReport')); ``` ## Parameter List ```text 'requestid' 'snmpversion' 'community' 'user' 'securitylevel' 'sourceaddress' 'sourceport' 'errorindex' 'errorstatus' 'errordescription' ``` ## Remarks For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the [ObjId](#objid-property-ipworkssnmp_snmpmgr-class), [ObjType](#objtype-property-ipworkssnmp_snmpmgr-class), and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. # Response Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when a GetResponse packet is received. ## Object Oriented Interface ```text public function fireResponse($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 12, array($this, 'fireResponse')); ``` ## Parameter List ```text 'requestid' 'snmpversion' 'community' 'user' 'securitylevel' 'sourceaddress' 'sourceport' 'errorindex' 'errorstatus' 'errordescription' ``` ## Remarks The *ErrorStatus* and *ErrorIndex* parameters contain information about possible errors. *ErrorDescription* is a textual description of *ErrorStatus*. This value is parsed directly from the SNMP response, which will be a one-based value, so a value of i here maps to index i-1 in the Objects collection. The following is a list of valid SNMP status code values: | | | | --- | --- | | 0 (noError) | No error. | | 1 (tooBig) | The response cannot fit in a single SNMP message. | | 2 (noSuchName) | Variable does not exist. | | 3 (badValue) | Invalid value or syntax. | | 4 (readOnly) | Variable is read-only. | | 5 (genError) | Other error (SNMPv1). | | 6 (noAccess) | Access denied. | | 7 (wrongType) | Wrong object type. | | 8 (wrongLength) | Wrong length. | | 9 (wrongEncoding) | Wrong encoding. | | 10 (wrongValue) | Wrong value. | | 11 (noCreation) | No creation. | | 12 (inconsistentValue) | Inconsistent value. | | 13 (resourceUnavailable) | Resource unavailable. | | 14 (commitFailed) | Commit failed. | | 15 (undoFailed) | Undo failed. | | 16 (authorizationError) | Authorization error. | | 17 (notWritable) | Variable is not writable. | | 18 (inconsistentName) | Inconsistent name. | The *ErrorIndex* parameter indicates the index of the first variable (object) that caused an error. The default value is 0. Variable indexes start with 0. *ErrorIndex* has no meaning when *ErrorStatus* is 0 (no error). The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the [ObjId](#objid-property-ipworkssnmp_snmpmgr-class), [ObjType](#objtype-property-ipworkssnmp_snmpmgr-class), and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. # SSLClientAuthentication Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when the client presents its credentials to the server. ## Object Oriented Interface ```text public function fireSSLClientAuthentication($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 13, array($this, 'fireSSLClientAuthentication')); ``` ## Parameter List ```text 'remoteaddress' 'remoteport' 'certencoded' 'certsubject' 'certissuer' 'status' 'accept' ``` ## Remarks This event fires when a client connects to the class and presents a certificate for authentication. The *Accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not. When *Accept* is False, *Status* shows why the verification failed (otherwise, *Status* contains the string "OK"). *RemoteAddress* is the IP address of the connecting client. *RemotePort* is the source port of the connecting client. *CertEncoded* is the base64 encoded certificate presented by the client. *CertSubject* is the subject of the certificate presented by the client. *CertIssuer* is the subject of the issuer of the certificate presented by the client. *Status* is the status of the certificate. *Accept* defines whether the certificate is accepted. # SSLServerAuthentication Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fires when connecting to the server. ## Object Oriented Interface ```text public function fireSSLServerAuthentication($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 14, array($this, 'fireSSLServerAuthentication')); ``` ## Parameter List ```text 'remoteaddress' 'remoteport' 'certencoded' 'certsubject' 'certissuer' 'status' 'accept' ``` ## Remarks This event is where the client can decide whether to continue with the connection process or not. The *Accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not. When *Accept* is False, *Status* shows why the verification failed (otherwise, *Status* contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the *Accept* parameter to True. *RemoteAddress* is the IP address of the server. *RemotePort* is the source port of the server. *CertEncoded* is the base64 encoded certificate presented by the server. *CertSubject* is the subject of the certificate presented by the server. *CertIssuer* is the subject of the issuer of the certificate presented by the server. *Status* is the status of the certificate. *Accept* defines whether the certificate is accepted. # SSLStatus Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Shows the progress of the secure connection. ## Object Oriented Interface ```text public function fireSSLStatus($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 15, array($this, 'fireSSLStatus')); ``` ## Parameter List ```text 'remoteaddress' 'remoteport' 'message' ``` ## Remarks The event is fired for informational and logging purposes only. It is used to track the progress of the connection. *RemoteAddress* is the IP address of the remote machine. *RemotePort* is the port of the remote machine. *Message* is the log message. # Trap Event ([IPWorksSNMP_SNMPMgr](#snmpmgr-class) Class) Fired when a SNMP trap packet is received. ## Object Oriented Interface ```text public function fireTrap($param); ``` ## Procedural Interface ```text ipworkssnmp_snmpmgr_register_callback($res, 16, array($this, 'fireTrap')); ``` ## Parameter List ```text 'requestid' 'snmpversion' 'community' 'user' 'securitylevel' 'trapoid' 'timestamp' 'sourceaddress' 'sourceport' ``` ## Remarks The **SNMPTrapMgr** class should normally be used to receive traps, since it was designed and contains functionality specifically for that purpose. The SNMPMgr component can only receive traps from the agent that it is has most recently discovered with the [Discover](#discover-method-ipworkssnmp_snmpmgr-class) method. The *TrapOID* and *TimeStamp* parameters contain the Trap OID and TimeStamp. In the case of an SNMPv1 trap, there are two possible scenarios: First, if the enterprise of the trap is "1.3.6.1.6.3.1.1.5", *TrapOID* will be a concatenation of TrapEnterprise and GenericTrap + 1. For instance a TrapOID of "1.3.6.1.6.3.1.1.5.5" has a TrapEnterprise of "1.3.6.1.6.3.1.1.5" and a GenericTrap of "4". Second, In all other cases *TrapOID* will be a concatenation of the values for TrapEnterprise, GenericTrap, and SpecificTrap, separated by '.'. For SNMPv2 and above, they are read from the variable-value list (if available). For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. The SNMPMgr class is limited to accepting authenticated traps only for the user specified in [User](#user-property-ipworkssnmp_snmpmgr-class) and Password and from the engine specified in [RemoteEngineId](#remoteengineid-property-ipworkssnmp_snmpmgr-class) with time parameters in [RemoteEngineBoots](#remoteengineboots-property-ipworkssnmp_snmpmgr-class) and [RemoteEngineTime](#remoteenginetime-property-ipworkssnmp_snmpmgr-class) (usually this is the SNMP engine discovered through the last call to [Discover](#discover-method-ipworkssnmp_snmpmgr-class)). If authenticated traps come from a different engine, or for a different user, they are ignored, and a [BadPacket](#badpacket-event-ipworkssnmp_snmpmgr-class) event is fired instead. The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the [ObjId](#objid-property-ipworkssnmp_snmpmgr-class), [ObjType](#objtype-property-ipworkssnmp_snmpmgr-class), and [ObjValue](#objvalue-property-ipworkssnmp_snmpmgr-class) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. # Config Settings ([SNMPMgr](#snmpmgr-class) Class) The class accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the [Config](#config-method-ipworkssnmp_snmpmgr-class) method. ### SNMPManager Config Settings **AllowSingleStepDiscovery**: Whether to allow discovery to be completed in a single step.When making a discovery request in SNMPv3 while this setting is set to False (default), the component will send a second discovery request even if the agent responds to the first request with the EngineBoots and EngineTime. If set to True, the component will skip the second request if all the necessary information is returned in the first response. **CheckMessageOrigin**: Whether to match the origin IP address when receiving responses.This setting specifies whether the class matches the source IP address in the response to the destination IP address of the request. When True (default) the class makes sure that response are received from the same IP to which the request was sent. In most cases this does not need to be changed. If there is a specific reason that responses are expected to originate from a different IP from that which the request was sent, this may be set to False. When False the class will not check the origin of received responses. **CheckSNMPVersion**: Whether to check the version of incoming packets.By default only packets matching [SNMPVersion](#snmpversion-property-ipworkssnmp_snmpmgr-class) can be received. Set this to *false* to ignore the version of incoming packets. The default is *true*. **CompatibilityMode**: Whether to operate the component in a specific compatibility mode.This setting will cause the component to operate in a manner different than normal so that it is compatible with third-party products and libraries. The following table lists the possible values for this setting: | | | | --- | --- | | 0 (default) | Component operates normally for greatest compatibility. | | 1 | Component uses SNMP4j-compatible encryption (AES192 and AES256). | | 2 | Component automatically detects whether to use SNMP4j-compatible encryption (AES192 and AES256). Note: This option is only applicable when receiving packets. If you are using [SNMPMgr](#snmpmgr-class) or sending secure traps, you will need to select either 0 or 1. | **ContextEngineId**: Sets the context engine id of the SNMP entity. If set, the context engine id included in the PDU will be set. **ContextName**: Sets the context name of the SNMP entity. If set, the context name included in the PDU will be set. **DecryptLogPackets**: Whether to decrypt logged packets.When set to *true* this setting will cause the class to decrypt packets logged in [PacketTrace](#packettrace-event-ipworkssnmp_snmpmgr-class). This only applies when using SNMP Version 3. The default is *false*. **ForceLocalPort**: Forces the class to bind to a specific port. The default value is True, which makes the class throw an error if [LocalPort](#localport-property-ipworkssnmp_snmpmgr-class) is busy. When [ForceLocalPort](#ForceLocalPort) is set to False and the port is busy, the class silently chooses another random port. **IgnoreDuplicateResponse**: Whether to ignore duplicate responses.In some scenarios an agent may send a duplicate response (identified by it's *RequestID*). To prevent processing of a duplicate response set this to *true*. The default is *false* **IgnorePortMismatch**: Whether to check if the port matches when a response is received.When a response is received, the class will validate that the port in the response is the same as the port in the request. To disable this, set this to True. **IncomingContextEngineId**: The engine Id of the received packet.This setting holds the engine Id of the received packet. This may be queried at any time, including from within an event, and returns the engine Id of the received packet. This is not needed in most cases, but can be used to store the incoming engine Id to send an asynchronous response later. This value is read-only. **IncomingContextName**: The context name of the received packet.This setting holds the context name of the received packet. This may be queried at any time, including from within an event, and returns the context name of the received packet. This is not needed in most cases, but can be used to store the incoming context name to send an asynchronous response later. This value is read-only. **MsgMaxSize**: The maximum supported message size.This setting specifies the maximum supported message size in bytes. This is only applicable when [SNMPVersion](#snmpversion-property-ipworkssnmp_snmpmgr-class) is set to 3. This corresponds to the "msgMaxSize" field in the request. The default maximum message size is *16384* bytes. **SourceAddress**: The source address of the received packet.This setting holds the source address of the received packet. This may be queried at any time, including from within an event, and returns the source address of the received packet. This value is read-only. **SourcePort**: The source port of the received packet.This setting holds the source port of the received packet. This may be queried at any time, including from within an event, and returns the source port of the received packet. This value is read-only. **TimeoutInMilliseconds**: The timeout is treated as milliseconds.Setting **TimeoutInMilliseconds** to true causes the class to use the value in [Timeout](#timeout-property-ipworkssnmp_snmpmgr-class) as milliseconds instead of seconds, which is the default. **WalkInsideRange**: Stops the SNMP walk if the OID value returned from an agent is outside the table.When **WalkInsideRange** is set to true the Walk will continue only while the OID Values returned from the agent are greater than the current OID Value. If an object is returned with an OID value that is out of this range it is not added to the Objects collection, the [Error](#error-event-ipworkssnmp_snmpmgr-class) event will fire, and [Walk](#walk-method-ipworkssnmp_snmpmgr-class) will return. The default value is true. **WalkStartOID**: Specifies the OID to be used when a Walk is performed.When this property is set and [Walk](#walk-method-ipworkssnmp_snmpmgr-class) is called, the first request sent will contain the specified **WalkStartOID** value. This feature is particularly useful in the case of errors, such as timeouts, that may occur during a Walk. In such a case, you can set **WalkStartOID** to the last OID returned before the Timeout occurred then call [Walk](#walk-method-ipworkssnmp_snmpmgr-class) again (using the original tableOID parameter value). This will allow you to continue the Walk where it left off (when the Timeout error occurred). Note that when [StoreWalkObjects](#storewalkobjects-property-ipworkssnmp_snmpmgr-class) is set to true and **WalkStartOID** is set, the existing entries in Objects will be maintained when [Walk](#walk-method-ipworkssnmp_snmpmgr-class) is called and new returned objects will be added (just as if no error occurred in the initial [Walk](#walk-method-ipworkssnmp_snmpmgr-class) call). ### UDP Config Settings **CaptureIPPacketInfo**: Used to capture the packet information.If this is set to True, the component will capture the IP packet information. The default value for this setting is False. NOTE: This configuration setting is available only in Windows. **DelayHostResolution**: Whether the hostname is resolved when RemoteHost is set.This configuration setting specifies whether a hostname is resolved immediately when [RemoteHost](#remotehost-property-ipworkssnmp_snmpmgr-class) is set. If *true* the class will resolve the hostname and the IP address will be present in the [RemoteHost](#remotehost-property-ipworkssnmp_snmpmgr-class) property. If *false*, the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may be called to manually resolve the value in [RemoteHost](#remotehost-property-ipworkssnmp_snmpmgr-class) at any time. The default value is *false*. **DestinationAddress**: Used to get the destination address from the packet information.If [CaptureIPPacketInfo](#CaptureIPPacketInfo) is set to True, then this will be populated with the packet's destination address when a packet is received. This information will be accessible in the DataIn event. NOTE: This configuration setting is available only in Windows. **DontFragment**: Used to set the Don't Fragment flag of outgoing packets.When set to True, packets sent by the class will have the Don't Fragment flag set. The default value is False. **LocalHost**: The name of the local host through which connections are initiated or accepted. The [LocalHost](#localhost-property-ipworkssnmp_snmpmgr-class) setting contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address. In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classes) only through that interface. If the class is connected, the [LocalHost](#localhost-property-ipworkssnmp_snmpmgr-class) setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface). **LocalPort**: The port in the local host where the class binds. This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine. Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by [LocalPort](#localport-property-ipworkssnmp_snmpmgr-class) after the connection is established. [LocalPort](#localport-property-ipworkssnmp_snmpmgr-class) cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems. **MaxPacketSize**: The maximum length of the packets that can be received.This configuration setting specifies the maximum size of the datagrams that the class will accept without truncation. **QOSDSCPValue**: Used to specify an arbitrary QOS/DSCP setting (optional).[UseConnection](#UseConnection) must be True to use this configuration setting. This option allows you to specify an arbitrary DSCP value between 0 and 63. The default is 0. When set to the default value, the component will not set a DSCP value. NOTE: This configuration setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later. **QOSTrafficType**: Used to specify QOS/DSCP settings (optional).[UseConnection](#UseConnection) must be True to use this setting. You may specify either the text or integer values: BestEffort (0), Background (1), ExcellentEffort (2), AudioVideo (3), Voice (4), and Control (5). NOTE: This configuration setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above. NOTE: QOSTrafficType must be set before setting [Active](#active-property-ipworkssnmp_snmpmgr-class) to True. **ShareLocalPort**: If set to True, allows more than one instance of the class to be active on the same local port.This option must be set before the class is activated through the [Active](#active-property-ipworkssnmp_snmpmgr-class) property or it will have no effect. The default value for this setting is False. **SourceIPAddress**: Used to set the source IP address used when sending a packet.This configuration setting can be used to override the source IP address when sending a packet. NOTE: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility). **SourceMacAddress**: Used to set the source MAC address used when sending a packet.This configuration setting can be used to override the source MAC address when sending a packet. NOTE: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility). **UseConnection**: Determines whether to use a connected socket.[UseConnection](#UseConnection) specifies whether or not the class should use a connected socket. The connection is defined as an association in between the local address/port and the remote address/port. As such, this is not a connection in the traditional Transmission Control Protocol (TCP) sense. It means only that the class will send and receive data to and from the specified destination. The default value for this setting is False. **UseIPv6**: Whether or not to use IPv6.By default, the component expects an IPv4 address for local and remote host properties, and it will create an IPv4 socket. To use IPv6 instead, set this to True. ### Socket Config Settings **AbsoluteTimeout**: Determines whether timeouts are inactivity timeouts or absolute timeouts.If [AbsoluteTimeout](#AbsoluteTimeout) is set to True, any method that does not complete within [Timeout](#timeout-property-ipworkssnmp_snmpmgr-class) seconds will be aborted. By default, *AbsoluteTimeout* is False, and the timeout is an inactivity timeout. NOTE: This option is not valid for User Datagram Protocol (UDP) ports. **FirewallData**: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes). **InBufferSize**: The size in bytes of the incoming queue of the socket.This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the *InBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the *InBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. **OutBufferSize**: The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the *OutBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the *OutBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. ### Base Config Settings **BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build. **CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

It will return the following information: - Product: The product the license is for. - Product Key: The key the license was generated from. - License Source: Where the license was found (e.g., RuntimeLicense, License File). - License Type: The type of license installed (e.g., Royalty Free, Single Server). - Last Valid Build: The last valid build number for which the license will work. **MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*. **ProcessIdleEvents**: Whether the class uses its internal event loop to process events when the main thread is idle.If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True. **SelectWaitMillis**: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.If there are no events to process when [DoEvents](#doevents-method-ipworkssnmp_snmpmgr-class) is called, the class will wait for the amount of time specified here before returning. The default value is 20. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the class will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the class to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section. # Trappable Errors ([SNMPMgr](#snmpmgr-class) Class) ### SNMPMgr Errors | | | | --- | --- | | 201 | Timeout. | | 301 | Bad Object Index when accessing the Obj* properties.
