The format of the default section is as follows:
BEGIN_DEFAULTS ClassName: SNMPTrap InstanceName: $SYS$ EventName: $E$ $N$ $S$ Severity: 2 EventText: Varbinds: $V*$ Expiration: 7200 State: NOTIFY InMaintenance: FALSE ClearOnAcknowledge: TRUE EventType: MOMENTARY SysNameOrAddr: $A$ UnknownAgent: IGNORE LogFile: NONE END_DEFAULTS
The default section demonstrates that you can use variables in descriptions. Of particular note is the use of the varbind variable with an asterisk for the EventText parameter. In this case, EventText stores the value of all of the varbinds associated with a trap. By defining LogFile, the SNMP Trap Adapter logs all of the traps unless a trap’s LogFile is defined as NONE.
