The SNMPTrapMgr component provides a UDP-based listening point for SNMP traps.

Syntax

TipnSNMPTrapMgr

Remarks

The SNMPTrapMgr component provides a UDP-based listening point for SNMP traps and informs as specified by the SNMP RFCs. The component supports v1, v2c, and v3 traps.

The component provides both encoding/decoding and transport capabilities, making the task of developing a custom SNMP Trap 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 component 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.

Messages are received through events such as Trap, InformRequest, or DiscoveryRequest.

SNMP OIDs, types, and values are provided in the Objects collection of SNMP objects for both sent and received packets.

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 AddUser, RemoveUser, ShowCache, ClearCache, AddEngine, and RemoveEngine 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.

AcceptData Property (SNMPTrapMgr Component)

Enables or disables data reception.

Syntax

__property bool AcceptData = { read=FAcceptData, write=FSetAcceptData };

Default Value

True

Remarks

Setting the property to False temporarily disables data reception. Setting the property to True re-enables data reception.

This property is not available at design time.

Data Type

Boolean

Active Property (SNMPTrapMgr Component)

Indicates whether the component is active.

Syntax

__property bool Active = { read=FActive, write=FSetActive };

Default Value

False

Remarks

This property indicates whether the component is currently active and can send or receive data.

The component will be automatically activated if it is not already and you attempt to perform an operation which requires the component to be active.

Note: Use the Activate or Deactivate method to control whether the component is active.

This property is not available at design time.

Data Type

Boolean

LocalEngineId Property (SNMPTrapMgr Component)

The Engine Id (for SNMPv3).

Syntax

__property String LocalEngineId = { read=FLocalEngineId, write=FSetLocalEngineId };
__property DynamicArray<Byte> LocalEngineIdB = { read=FLocalEngineIdB, write=FSetLocalEngineIdB };

Default Value

""

Remarks

This property is necessary for properly handling InformRequest packets.

Data Type

Byte Array

LocalHost Property (SNMPTrapMgr Component)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };

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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component 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 multi-homed 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 (SNMPTrapMgr Component)

The port in the local host where the component is bound to.

Syntax

__property int LocalPort = { read=FLocalPort, write=FSetLocalPort };

Default Value

162

Remarks

The LocalPort property must be set before the component is activated (Active is set to True). It instructs the component to bind to a specific port (or communication endpoint) in the local machine.

The default port is 162 (standard trap port). If that port is busy, an error will be returned, unless the ForceLocalPort configuration setting is set to False, in which case a random port will be chosen.

LocalPort cannot be changed once the component is Active. Any attempt to set the LocalPort property when the component is Active 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 (SNMPTrapMgr Component)

The number of records in the Obj arrays.

Syntax

__property int ObjCount = { read=FObjCount, write=FSetObjCount };

Default Value

0

This property is not available at design time.

Data Type

Integer

Activate Method (SNMPTrapMgr Component)

Activates the component.

Syntax

void __fastcall Activate();

Remarks

This method activates the component and will allow it to send or receive data.

The component will be automatically activated if it is not already and you attempt to perform an operation which requires the component to be active.

Note: Use the Active property to check whether the component is active.

AddEngine Method (SNMPTrapMgr Component)

Adds the engine specified by EngineId to the internal authentication cache.

Syntax

void __fastcall AddEngine(DynamicArray<Byte> EngineId, int EngineBoots, int EngineTime);

Remarks

The internal authentication cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.

The ShowCache method is used to show the contents of the internal authentication cache.

The ClearCache method can be used to completely clear the cache.

If the engine parameters are unknown, the SNMPMgr component's Discover method can be used to perform a discovery with the agent. The RemoteEngineId, RemoteEngineTime, and RemoteEngineBoots properties will hold the values that can then be passed to this method.

AddUser Method (SNMPTrapMgr Component)

Adds a user for the engine specified by EngineId to the internal authentication cache.

Syntax

void __fastcall AddUser(String User, DynamicArray<Byte> EngineId, int AuthenticationProtocol, String AuthenticationPassword, int EncryptionAlgorithm, String EncryptionPassword);

Remarks

The internal authentication cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.

The ShowCache method is used to show the contents of the internal authentication cache.

The ClearCache method can be used to completely clear the cache.

ClearCache Method (SNMPTrapMgr Component)

Clears the internal authentication database.

Syntax

void __fastcall ClearCache();

Remarks

All user and engine records are removed from the internal authentication cache as a result of this call.

Config Method (SNMPTrapMgr Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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, you must call Config("PROPERTY"). The value will be returned as a string.

Deactivate Method (SNMPTrapMgr Component)

Deactivates the component.

Syntax

void __fastcall Deactivate();

Remarks

This method deactivates the component and will prohibit it from sending and receiving data.

Note: Use the Active property to check whether the component is active.

DoEvents Method (SNMPTrapMgr Component)

Processes events from the internal message queue.

Syntax

void __fastcall DoEvents();

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

HashPasswords Method (SNMPTrapMgr Component)

Hashes all passwords in the cache.

Syntax

void __fastcall HashPasswords();

Remarks

Forces computation of all passwords hashes in the cache. Used together with the HashPassword event to enable implementations of external password hash storage.

RemoveEngine Method (SNMPTrapMgr Component)

Removes the engine specified by EngineId from the internal authentication cache.

Syntax

void __fastcall RemoveEngine(DynamicArray<Byte> EngineId);

Remarks

The internal authentication cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.

The ShowCache method is used to show the contents of the internal authentication cache.

The ClearCache method can be used to completely clear the cache.

RemoveUser Method (SNMPTrapMgr Component)

Removes the user specified by User of the engine specified by EngineId from the internal authentication cache.

Syntax

void __fastcall RemoveUser(String User, DynamicArray<Byte> EngineId);

Remarks

The internal authentication cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.

The ShowCache method is used to show the contents of the internal authentication cache.

The ClearCache method can be used to completely clear the cache.

Reset Method (SNMPTrapMgr Component)

Clears the object arrays.

Syntax

void __fastcall Reset();

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 will be reset to snmpverV2c (2).

ShowCache Method (SNMPTrapMgr Component)

Lists all entries in the internal user and engine database.

Syntax

void __fastcall ShowCache();

Remarks

A CacheEntry event is fired for every record in the database.

Value Method (SNMPTrapMgr Component)

Returns the value corresponding to an OID.

Syntax

String __fastcall Value(String 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.

BadPacket Event (SNMPTrapMgr Component)

Fired for erroneous and/or malformed messages.

Syntax

typedef struct {
  String Packet;
  DynamicArray<Byte> PacketB;
  String SourceAddress;
  int SourcePort;
  int ErrorCode;
  String ErrorDescription;
  bool Report;
} TipnSNMPTrapMgrBadPacketEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrBadPacketEvent)(System::TObject* Sender, TipnSNMPTrapMgrBadPacketEventParams *e);
__property TipnSNMPTrapMgrBadPacketEvent OnBadPacket = { read=FOnBadPacket, write=FOnBadPacket };

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.

Please refer to the GetUserPassword event for more information concerning SNMPv3 authentication.

CacheEntry Event (SNMPTrapMgr Component)

Shows engines and users in the internal cache.

Syntax

typedef struct {
  String EngineId;
  DynamicArray<Byte> EngineIdB;
  int EngineBoots;
  int EngineTime;
  String User;
  String AuthenticationProtocol;
  String AuthenticationPassword;
  String EncryptionAlgorithm;
  String EncryptionPassword;
} TipnSNMPTrapMgrCacheEntryEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrCacheEntryEvent)(System::TObject* Sender, TipnSNMPTrapMgrCacheEntryEventParams *e);
__property TipnSNMPTrapMgrCacheEntryEvent OnCacheEntry = { read=FOnCacheEntry, write=FOnCacheEntry };

Remarks

CacheEntry events are triggered by a call to ShowCache. One event is fired for each user and engine. If there are no users for a particular engine, a single event is fired with the engine information, but empty values for user information.

CheckEngine Event (SNMPTrapMgr Component)

Fired to check engine parameters (timeliness, etc.).

Syntax

typedef struct {
  String EngineId;
  DynamicArray<Byte> EngineIdB;
  int EngineBoots;
  int EngineTime;
  String User;
  int SecurityLevel;
  String RemoteAddress;
  int RemotePort;
  bool IsNew;
  bool Accept;
} TipnSNMPTrapMgrCheckEngineEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrCheckEngineEvent)(System::TObject* Sender, TipnSNMPTrapMgrCheckEngineEventParams *e);
__property TipnSNMPTrapMgrCheckEngineEvent OnCheckEngine = { read=FOnCheckEngine, write=FOnCheckEngine };

Remarks

The Accept parameter determines if the engine will be accepted or not. If you set Accept to False prior to exiting the event, the processing on the message will stop and a BadPacket event will be fired.

The default value of Accept is True if and only if:

a) the engine already exists in the internal authentication cache (the IsNew parameter is False) and the timeliness has been verified;

b) the engine does not exist in the internal authentication cache (the IsNew parameter is True), but the packet has been authenticated by the component (SecurityLevel >= 1).

In all other cases, the default value for Accept is False, and you are responsible for accepting or not accepting the engine based on other considerations.

If Accept is true upon event exit, then:

a) if the engine already exists in the internal authentication cache, its time is updated to reflect the new time and the processing of the packet continues;

b) if the engine does not exist in the internal authentication cache, it is added there and if User is authenticated, the User will be added too.

DiscoveryRequest Event (SNMPTrapMgr Component)

Fired when an SNMPv3 discovery packet is received.

Syntax

typedef struct {
  String EngineId;
  DynamicArray<Byte> EngineIdB;
  int EngineBoots;
  int EngineTime;
  String User;
  int SecurityLevel;
  String SourceAddress;
  int SourcePort;
  bool Respond;
} TipnSNMPTrapMgrDiscoveryRequestEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrDiscoveryRequestEvent)(System::TObject* Sender, TipnSNMPTrapMgrDiscoveryRequestEventParams *e);
__property TipnSNMPTrapMgrDiscoveryRequestEvent OnDiscoveryRequest = { read=FOnDiscoveryRequest, write=FOnDiscoveryRequest };

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. 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).

Error Event (SNMPTrapMgr Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TipnSNMPTrapMgrErrorEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrErrorEvent)(System::TObject* Sender, TipnSNMPTrapMgrErrorEventParams *e);
__property TipnSNMPTrapMgrErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

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 section.

GetUserPassword Event (SNMPTrapMgr Component)

Retrieves a password associated with a user.

Syntax

typedef struct {
  int PasswordType;
  String User;
  String EngineId;
  DynamicArray<Byte> EngineIdB;
  String Password;
  int Algorithm;
} TipnSNMPTrapMgrGetUserPasswordEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrGetUserPasswordEvent)(System::TObject* Sender, TipnSNMPTrapMgrGetUserPasswordEventParams *e);
__property TipnSNMPTrapMgrGetUserPasswordEvent OnGetUserPassword = { read=FOnGetUserPassword, write=FOnGetUserPassword };

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 and EngineId 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:

ValueAuthentication Algorithm
0 (default)Any
1MD5
2SHA1
3SHA256
4SHA512
If the PasswordType parameter is 2 (encryption is used), the Algorithm parameter must also be set. Possible values are:
ValueEncryption Algorithm
1 (default)DES
2AES
33DES
4AES192
5AES256

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 (SNMPTrapMgr Component)

Sets the security level for an incoming packet.

Syntax

typedef struct {
  String User;
  String EngineId;
  DynamicArray<Byte> EngineIdB;
  int SecurityLevel;
} TipnSNMPTrapMgrGetUserSecurityLevelEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrGetUserSecurityLevelEvent)(System::TObject* Sender, TipnSNMPTrapMgrGetUserSecurityLevelEventParams *e);
__property TipnSNMPTrapMgrGetUserSecurityLevelEvent OnGetUserSecurityLevel = { read=FOnGetUserSecurityLevel, write=FOnGetUserSecurityLevel };

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:

-1The message will be ignored and a BadPacket event will be fired.
0No security. The message will be processed without any authentication and/or encryption.
1Authentication only. The message will be checked for a valid signature and the GetUserPassword event will be fired to verify the authentication password.
2Authentication 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 (SNMPTrapMgr Component)

Fired before and after a password is hashed.

Syntax

typedef struct {
  String Password;
  int AuthAlgorithm;
  String Hash;
} TipnSNMPTrapMgrHashPasswordEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrHashPasswordEvent)(System::TObject* Sender, TipnSNMPTrapMgrHashPasswordEventParams *e);
__property TipnSNMPTrapMgrHashPasswordEvent OnHashPassword = { read=FOnHashPassword, write=FOnHashPassword };

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 component 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 (SNMPTrapMgr Component)

Fired when an InformRequest packet is received.

Syntax

typedef struct {
  int RequestId;
  int SNMPVersion;
  String Community;
  String User;
  int SecurityLevel;
  String SourceAddress;
  int SourcePort;
  int ErrorIndex;
  int ErrorStatus;
  String ErrorDescription;
  bool Respond;
} TipnSNMPTrapMgrInformRequestEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrInformRequestEvent)(System::TObject* Sender, TipnSNMPTrapMgrInformRequestEventParams *e);
__property TipnSNMPTrapMgrInformRequestEvent OnInformRequest = { read=FOnInformRequest, write=FOnInformRequest };

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 user in an InformRequest packet (SNMPv3) must be a valid user in the internal authentication cache (see the AddUser method and the CheckEngine event for more information). If not, the request is rejected, and a BadPacket 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, 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.
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 (SNMPTrapMgr Component)

Fired for every packet sent or received.

Syntax

typedef struct {
  String Packet;
  DynamicArray<Byte> PacketB;
  int Direction;
  String PacketAddress;
  int PacketPort;
} TipnSNMPTrapMgrPacketTraceEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrPacketTraceEvent)(System::TObject* Sender, TipnSNMPTrapMgrPacketTraceEventParams *e);
__property TipnSNMPTrapMgrPacketTraceEvent OnPacketTrace = { read=FOnPacketTrace, write=FOnPacketTrace };

Remarks

The PacketTrace event shows all the packets sent or received by the component.

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.

Trap Event (SNMPTrapMgr Component)

Fired when a SNMP trap packet is received.

Syntax

typedef struct {
  int RequestId;
  int SNMPVersion;
  String Community;
  String User;
  int SecurityLevel;
  String TrapOID;
  __int64 TimeStamp;
  String AgentAddress;
  String SourceAddress;
  int SourcePort;
} TipnSNMPTrapMgrTrapEventParams;
typedef void __fastcall (__closure *TipnSNMPTrapMgrTrapEvent)(System::TObject* Sender, TipnSNMPTrapMgrTrapEventParams *e);
__property TipnSNMPTrapMgrTrapEvent OnTrap = { read=FOnTrap, write=FOnTrap };

Remarks

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 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.

Some parameters are only applicable depending on the SNMPVersion value. The table below shows which parameters are applicable to which SNMP versions.

SNMPv1 SNMPv2 SNMPv3
AgentAddress X
Community X X
RequestId X X
SecurityLevel X
User X
SNMPVersion X X X
SourceAddress X X X
SourcePort X X X
TimeStamp X X X
TrapOID X X X

Config Settings (SNMPTrapMgr Component)

The component 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 component, access to these internal properties is provided through the Config method.

SNMPTrapMgr Config Settings

AuthenticationKey:   The key to use for authentication.

This setting takes the hex-encoded key for authentication and may be set inside GetUserPassword.

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.
1Component uses SNMP4j-compatible encryption (AES192 and AES256).
2Component 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.
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 component to decrypt packets logged in PacketTrace. This only applies when using SNMP Version 3. The default is false.

EncryptionKey:   The key to use for encryption.

This setting takes the hex-encoded key for encryption and may be set inside GetUserPassword.

ForceLocalPort:   Forces the component to bind to a specific port.

The default value is True, which makes the component throw an error if LocalPort is busy. When ForceLocalPort is set to False and the port is busy, the component silently chooses another random port.

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.

ShowCacheForUser:   Shows the cache entry for a single user.

This configuration setting causes the component to call ShowCache internally, and only fire the CacheEntry event for the user specified.

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.

TimeWindow:   The time window used for SNMPv3 timeliness checking (authentication).

The default value is 150 (seconds).

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 setting is only available in Windows.

DelayHostResolution:   Whether the hostname is resolved when RemoteHost is set.

This setting specifies whether a hostname is resolved immediately when RemoteHost is set. If true the component will resolve the hostname and the IP address will be present in the RemoteHost 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 called to manually resolve the value in RemoteHost at any time.

The default value is false.

DestinationAddress:   Used to get the destination address from the packet information.

If 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 setting is only available in Windows.

DontFragment:   Used to set the Don't Fragment flag of outgoing packets.

When set to True, packets sent by the component 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 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component 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 multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the component binds.

This must be set before a connection is attempted. It instructs the component 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 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; setting is useful when trying to connect to services that require a trusted port in 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 setting specifies the maximum size of the datagrams that the component will accept without truncation.

QOSDSCPValue:   Used to specify an arbitrary QOS/DSCP setting (optional).

UseConnection must be True to use this 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 setting uses the qWAVE API is only available on Windows 7, Windows Server 2008 R2, and later.

QOSTrafficType:   Used to specify QOS/DSCP settings (optional).

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 setting uses the qWAVE API which is only available on Windows Vista and Windows Server 2008 or above.

Note: QOSTrafficType must be set before setting Active to true.

ShareLocalPort:   If set to True, allows more than one instance of the component to be active on the same local port.

This option must be set before the component is activated through the Active property or it will have no effect.

The default value for this setting is False.

UseConnection:   Determines whether to use a connected socket.

UseConnection specifies whether the component should use a connected socket or not. 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 TCP sense. What it means is only that the component will send and receive data only 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 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 is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component 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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component 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).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. 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.
MaskSensitive:   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.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
