Static elements

The probe generates the same set of static elements for each event it receives.

The following table describes the elements that the Probe for Nokia-Siemens TNMS-SNMP Interface generates. Not all the elements described are generated for each event; the static elements that the probe generates depends upon the event type.

Table 1. Static elements
Element name	SNMP version	Description
`$community`	V1 and V2c	This element contains the SNMP community string.
`$contextEngineID`	V3	This element identifies the engine associated with the data.
`$enterprise`	V1	This element contains the SNMP enterprise string.
`$EventCount`	V1, V2c, and V3	This element contains the number of traps processed during the current execution of the probe.
`$generic-trap`	V1	This element contains the SNMP generic trap integer value.
`$IPaddress`	V1, V2c, and V3	This element contains the IP address (origin of the SNMP trap).
`$Node`	V1, V2c, and V3	This element contains the node name (origin of the SNMP trap) or IP address (if node name cannot be resolved).
`$notify`	V2c and V3	This element contains notify V2c specific field.
`$PeerAddress`	V1, V2c, and V3	This element contains the host name or IP address from which the SNMP trap wasreceived.
`$PeerIPaddress`	V1, V2c, and V3	This element contains the IP address from which the SNMP trap was received.
`$Protocol`	V1, V2c, and V3	This element contains the protocol of the trap received. This can be either UDP or TCP.
`$ReceivedPort`	V1, V2c, and V3	This element contains the port number from which the SNMP trap was received. This is determined by the Port property.
`$ReceivedTime`	V1, V2c, and V3	This element contains the time that the SNMP packet was received from the network interface.
`$ReqId`	V1	This element contains the SNMP request ID.
`$securityEngineID`	V3	This element contains the engine ID of the authoritative SNMP entity. For informs, this is the engine ID of the probe. For traps, this is the engine ID of the source of the trap.
`$securityLevel`	V3	This element contains the security level of the trap or inform: noAuth: Trap or inform had no authentication and no privacy. authNoPriv: Trap or inform had authentication, but no privacy. authPriv: Trap or inform had authentication and privacy.
`$securityName`	V3	This element contains security name used for trap authentication.
`$Sequence`	V1 and V2c	This element contains a value unique to each execution of the probe. The first time the probe is run, this value is set to 1; it is then incremented by one each time the probe is run.
`$SNMP_Version`	V1, V2c, and V3	This element has the value 1 for SNMP V1 traps and the value 2 for SNMP V2c traps.
`$specific-trap`	V1	This element contains the SNMP specific trap integer value.
`$Uptime`	V2c	This element contains the SNMP uptime for V2c traps. This is provided in the following format (0:00:00).
`$UpTime`	V1	This element contains the SNMP uptime for V1 traps. This is formatted as an integer.
