SNMP v3 send traps to NMS


I'm trying to set up SNMPv3 on a 2950 switch. I can pull information from the switch like my information about the interface. But no traps comes from the switch to NMS (Whats up gold).

This is my config

snmp-server group mygroup v3 auth

snmp-server user myuser mygroup v3 auth md5 cisco

snmp-server host x.x.x.x ver 3 auth myuser

snmp-server enable traps

After i have created som vlans and shut down some interfaces I dont see any "send traps" (show snmp)

What is the proper way to do this.

I want

1. pull information about interface, cpu and mem.

2. I want traps to my NMS

best regards

Re: SNMP v3 send traps to NMS

This should work to enable all traps on a 2950 running recent code:

snmp-server group v3tgrp v3 notify v1default

snmp-server user tuser v3tgrp v3 auth md5 cisco

snmp-server enable traps

snmp-server host traps version 3 auth tuser

After entering these commands, show snmp should look like:


SNMP logging: enabled

Logging to, 0/10, 3 sent, 0 dropped.

SNMP agent enabled

You should also see a list of specific traps enabled in the config. If, after entering these commands, traps are still not working, please post the show snmp and complete show run. If you cannot share that information on an open forum, then please open a TAC service request with the same information.
