Trailing .0 on the End of the Var Binds in SNMP Traps in 1.21 and 1.22 snmpgtw


Article ID: 34356


Updated On:


DX Unified Infrastructure Management (Nimsoft / UIM) NIMSOFT PROBES



Traps are not recognized and there is an unexpected trailing .0 on the End of the OID in version 1.07 to 1.31 of the snmpgtw probe.



Any environment that is using the probe snmpgtw version from 1.07 to 1.31.



Traps is not recognized

Looking at the Nimsoft published mib definition there appears to be a .0 append to the end of every trap varbind that is sent from either version 1.21 or 1.22 of this probe.

The MIB states:

nimsoft OBJECT IDENTIFIER ::= { enterprises 4055 }
sysadm OBJECT IDENTIFIER ::= { nimsoft 1 }
alarm OBJECT IDENTIFIER ::= { sysadm 1

and for example the alarm desc:

alarmDescr OBJECT-TYPE
ACCESS read-only
STATUS mandatory
"The alarmDescr object type is used to give a
textual description of a NimBUS alarm."
::= { alarm 3

This means that the oid should be enterprises.4055.1.1.3 yet it comes through as - enterprises.4055.

Example trap (repost this is my message text) :

Dec 29 2011 10:27:00 * [default] public 'enterprises.4055.' = '0' 'enterprises.4055.' = '1325175071' 'enterprises.4055.' = '21600' 'enterprises.4055.' = 'XP72562497-32730' 'enterprises.4055.' = 'co-ps-nms-a06' 'enterprises.4055.' = 'CPS' 'enterprises.4055.' = 'repost this6' 'enterprises.4055.' = '' 'enterprises.4055.' = 'nas' 'enterprises.4055.' = 'CPS_PrimaryHub' 'enterprises.4055.' = 'ChrisisnotaRookie' 'snmpTrapOID.0' = 'enterprises.4055.' 'sysDescr.0' = 'NimBUS/SNMP gateway' 'sysUpTime.0' = '0'

From tcpdump - so you know this is coming from Nimsoft:

TCP dump command

tcpdump -vvv -s 0 -i any 'host and port 162'



Upgrade to snmpgtw version 1.32 or above.


Fixed the issue of trailing .0 at the end of the Variable Binds in SNMP Traps generated by the probe
