How to parse OID from a trap's varbind



To parse the OID from a trap's varbind, do the following:
  1. Open the trap_mgr.conf configuration file as follows:

    <BASEDIR>/SAM/smarts/bin/sm_edit conf/icoi/trap_mgr.conf

    # ciscoSlbRealStateChange
    BEGIN_TRAP .1.3.6.1.4.1.9.9.161.2 6 2
            ClassName:      SNMPTrap
            InstanceName:   $SYS$
            EventName:      ciscoSlbRealStateChange
            Severity:       3
            EventText:      The 1 Varibles are - slbRealState= $V1$
            Expiration:     100
            State:          NOTIFY
            ASL:  my_trap_rules.asl
            LogFile:        CSM_Trap.log


    END_TRAP


     
  2. Customize the my_trap_rules.asl file according to your requirements and put it into the following directory:

    <BASEDIR>/SAM/smarts/local/rules/icoi-trapd/

    See the Note statement for the contents of this file.

     
  3. Restart trap adapter for the changes to take effect. The Event Text for the example will be:
CSM Slot:6 SHAREPOINT IP:10.1.51.127 SlbRealServerState:probeFailed
