Remarks
The SNMPAgent class implements a UDP-based standard SNMP Agent as specified in the SNMP RFCs. The class supports SNMP v1, v2c, and v3.
SNMP over DTLS is also supported when SSLEnabled is set to True. When acting as a client, the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the DTLS handshake. Additional SSL-related settings are also supported through the Config 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 property can be set to True and the SSLClientAuthentication 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 agent as simple as setting a few key properties and handling a few events. SNMP data such as 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 or Deactivate method. These methods enable or disable sending and receiving. The activation status can be found in the Active property.
The class operates asynchronously. Requests are received through events such as GetRequest, GetBulkRequest, GetNextRequest, etc. and the corresponding responses are automatically sent when the events return. Traps are sent through the SendTrap method.
SNMPv3 USM security passwords are requested through the GetUserPassword event, and event parameters such as User and SecurityLevel provide information about the security attributes of received requests, and enable granular decision capability about what to provide and what not to provide. The SendSecureTrap method is used to send authenticated (secure) SNMPv3 traps.
The AddUser, RemoveUser, ShowCache, and ClearCache methods are used to manage an internal authentication cache. This internal cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.
SNMP OIDs, types, and values are provided in the Objects collection of SNMP objects for both sent and received packets.
Other packet information is provided through corresponding event parameters, such as Community, or RequestId.

Default Value
false
Remarks
This property indicates whether the class is currently active and can 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.
Use the Activate and Deactivate methods to control whether the class is active.
This property is not available at design time.
Data Type
Boolean
LocalEngineId Property (IPWorksSNMP_SNMPAgent Class)
The Engine Id of the SNMP Agent.
Object Oriented Interface
public function getLocalEngineId(); public function setLocalEngineId($value);
Procedural Interface
ipworkssnmp_snmpagent_get($res, 3 ); ipworkssnmp_snmpagent_set($res, 3, $value );
Default Value
''
Remarks
This property is only used for SNMPv3 packets (when SNMPVersion is 3).
Data Type
Binary String
LocalHost Property (IPWorksSNMP_SNMPAgent Class)
This property includes the name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Object Oriented Interface
public function getLocalHost(); public function setLocalHost($value);
Procedural Interface
ipworkssnmp_snmpagent_get($res, 4 ); ipworkssnmp_snmpagent_set($res, 4, $value );
Default Value
''
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.
Data Type
String
LocalPort Property (IPWorksSNMP_SNMPAgent Class)
The port in the local host where the class listens.
Object Oriented Interface
public function getLocalPort(); public function setLocalPort($value);
Procedural Interface
ipworkssnmp_snmpagent_get($res, 5 ); ipworkssnmp_snmpagent_set($res, 5, $value );
Default Value
161
Remarks
The LocalPort property must be set before the class is activated (Active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine (default 161).
You may also set LocalPort to 0. This allows the TCP/IP stack to choose a port at random. The value chosen is provided via the LocalPort property after the class is activated through the Active property.
LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.
Note: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024.

public function doSendTrap($remotehost, $trapoid);
Procedural Interface
ipworkssnmp_snmpagent_do_sendtrap($res, $remotehost, $trapoid);
Remarks
Depending upon the value of the SNMPVersion property, the packet is constructed as an SNMPv1 or SNMPv2 Trap PDU. The following configuration settings provide more control about how traps are generated: TrapPort, TrapAgentAddress, TrapCommunity, TrapEnterprise. The SysUpTime property provides the trap timestamp.
SendTrap sends an unauthenticated trap. The SendSecureTrap method is used to send authenticated SNMPv3 traps.
If any values are provided in the Objects collection, they are sent unchanged. In the case of an SNMPv2 or SNMPv3 Trap, if Objects has a count that is equal to 0, the following values are set: sysUpTime.0 equal to SysUpTime and snmpTrapOID.0 equal to TrapOID.
For SNMPv2 and SNMPv3 Traps, TrapOID must contain the full OID of the Trap. For SNMPv1, TrapOID must be a string of the form "generic.specific" where generic and specific are numeric values providing the Trap Generic Type and Specific Type.
For SNMPv1, TrapOID must be of the form "GenericTrap.SpecificTrap". These values are sent in the PDU header. TrapAgentAddress and TrapEnterprise are taken from the corresponding configuration settings.
Additionally, the following symbolic values are recognized and translated as follows:
Trap Name | OID (SNMPv2 and above) | SNMPv1 GenericType |
coldStart | 1.3.6.1.6.3.1.1.5.1 | 0 |

Remarks
This is only available for SNMP versions 2 and 3.
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, ObjType, and ObjValue 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. |
Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).
A GetBulkRequest is very similar to a GetNextRequest, the difference is that Getbulk performs a continuous GetNext operation based on the MaxRepitions 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 MaxRepitions 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 MaxRepitions. Thus the SNMPMgr is expecting to receive N + M x (X - N) objects, assuming that each object has M successors.
GetNextRequest Event (IPWorksSNMP_SNMPAgent Class)
Fired when a GetNextRequest packet is received.

GetUserPassword Event (IPWorksSNMP_SNMPAgent Class)
Retrieves a password associated with a user.
Object Oriented Interface
public function fireGetUserPassword($param);
Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 10, array($this, 'fireGetUserPassword'));
Parameter List
'passwordtype'
'user'
'password'
'algorithm'
Remarks
The GetUserPassword event is fired after initial inspection of SNMPv3 requests.
The type of password required is provided in the PasswordType parameter: 1 for authentication, and 2 for encryption (privacy).
The password corresponding to User (if any) must be provided in the Password parameter. If the password is valid, processing will continue to other events such as GetRequest, SetRequest, etc.
If the PasswordType parameter is 1 (authentication is used), the Algorithm parameter can be set. Possible values are:
Value | Authentication Algorithm |
0 (default) | Any |
1 | MD5 |
2 | SHA1 |
3 | SHA256 |
4 | SHA512 |
Value | Encryption Algorithm |
1 (default) | DES |
2 | AES |
3 | 3DES |
4 | AES192 |
5 | AES256 |
If the password does not match the signature in the request, a BadPacket event will be fired, at which point you can decide whether to report the error to the client (see the description of the BadPacket event for more information).
If the User is invalid or unknown, set the password to empty string (default) to ignore the request. This will result in a BadPacket event being fired, at which point you can decide whether to report the error to the client or not.
GetUserSecurityLevel Event (IPWorksSNMP_SNMPAgent Class)
Sets the security level for an incoming packet.
Object Oriented Interface
public function fireGetUserSecurityLevel($param);
Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 11, array($this, 'fireGetUserSecurityLevel'));
Parameter List
'user'
'engineid'
'securitylevel'
Remarks
The GetUserSecurityLevel event is fired after the first inspection of each SNMPv3 request. The SecurityLevel parameter determines the level of security for the message.
On entry, the SecurityLevel parameter contains the default security level for User if the user is located in the internal cache, or if the User is not found in the cache, the SecurityLevel will be -1.
The value of SecurityLevel upon exiting the event, determines how the message will be processed:
-1 | The message will be ignored and a BadPacket event will be fired. |
0 | No security. The message will be processed without any authentication and/or encryption. |
1 | Authentication only. The message will be checked for a valid signature and the GetUserPassword event will be fired to verify the authentication password. |
2 | Authentication and Privacy. The message will be checked for a valid signature and the GetUserPassword event will be fired twice: first to verify the authentication password, and then to verify the privacy password. |
HashPassword Event (IPWorksSNMP_SNMPAgent Class)
Fired before and after a password is hashed.
Object Oriented Interface
public function fireHashPassword($param);
Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 12, array($this, 'fireHashPassword'));
Parameter List
'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
PacketTrace Event (IPWorksSNMP_SNMPAgent Class)
Fired for every packet sent or received.
Object Oriented Interface

Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 13, array($this, 'firePacketTrace'));
Parameter List
'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_SNMPAgent Class)
Fired when the class is ready to send data.
Object Oriented Interface
public function fireReadyToSend($param);
Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 14, array($this, 'fireReadyToSend'));
Parameter List
Remarks
The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend(TBD. DataToSend is removed).
Report Event (IPWorksSNMP_SNMPAgent Class)
Fired when a Report packet is received.
Object Oriented Interface
public function fireReport($param);
Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 15, array($this, 'fireReport'));
Parameter List
'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, ObjType, and ObjValue 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.
SetRequest Event (IPWorksSNMP_SNMPAgent Class)
Fired when a SetRequest packet is received.
Object Oriented Interface
public function fireSetRequest($param);
Procedural Interface
ipworkssnmp_snmpagent_register_callback($res, 16, array($this, 'fireSetRequest'));
Parameter List
'requestid'
'messageid'
'snmpversion'
'community'
'user'
'securitylevel'
'sourceaddress'
'sourceport'
'errorindex'
'errorstatus'
'errordescription'
'respond'
Remarks
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, ObjType, and ObjValue 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. |

Parameter List
'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 port of the remote machine.
Message is the log message.
Config Settings (SNMPAgent 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 method.SNMPAgent Config Settings
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 or sending secure traps, you will need to select either 0 or 1. |
A valid port number (a value between 1 and 65535) is required. The default value is 162.
UDP Config Settings
The default value for this setting is False.
Note: This configuration setting is available only in Windows.
The default value is false.
Note: This configuration setting is available only in Windows.
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 classs) only through that interface.
If the class is connected, the LocalHost 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).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort 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.
Note: This configuration setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later.
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 to True.
The default value for this setting is False.
Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).
Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).
The default value for this setting is False.
Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
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.
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.
