SNMP Traps are not sent from Cisco router to Microfocus NNMi

[Ruzanna Zohrabyan]

Hello I have Cisco router 2951(IOS 15.0) and Microfocus NNMi monitoring system.

Router is discovered by NNMi and configured to monitor interfaces properly. Actually it is working when NNMI requests NNMi traps (with 5m interval). And when some interface goes down router doesn't sent traps to NNMi.

I have tried troubleshoot by debugging snmp packets, and no snmp traps sent.

What maybe the reason?

Thanks in advance!

Hi there,

Can you share the output of: sh run | inc snmp-server

cheers,

Seb.

Hello,

sure, here is the output:

Hi there,

Although these commands should be defaults (by the presence of the other current commands) can you try explicitly adding them:

!
snmp-server enable traps
snmp-server host 192.168.0.166 traps version 2c sitescope
!

cheers,

Seb.

Hello dear Seb Rupik,

I added commands you have provided. In the running-config nothing changed, and NNMi doesn't receive SNMP traps still.

Can you try manually configuring "snmp trap link-status" on an interface and triggering it?  Keep debug running and monitored.  Also, do you have link traps working on another 2950 in your network?
