SNMPv3 sample config (3750)

Answered Question
Dec 5th, 2007

Does anyone have a short sample config for SNMPv3 I can use as a model on a 3750? I'm wanting to collect stats and push/pull config and IOS changes with CW2000 using SNMPv3.


I have this problem too.

snmp-server group v3group v3 auth write v1default

snmp-server user v3user v3group v3 auth md5 v3user123

Since the 3750 is a switch, you will also need to add a group entry for each VLAN context (if you want Campus Manager to work with it). Use the "show snmp context" command to see all contexts. For each one, you need to add:

snmp-server group v3group v3 context CONTEXT

Where CONTEXT is one of the contexts seen in the output of "show snmp context".

Is it the same on a 6509? (Modular IOS) as far as the CONTEXT and vlans?

For some reason it doesn't like the (context) key word. Am I missing a something?

#snmp-server group v3group v3 context vlan-177


% Invalid input detected at '^' marker.

snmp-server group v3group v3 ?

auth group using the authNoPriv Security Level

noauth group using the noAuthNoPriv Security Level

priv group using SNMPv3 authPriv security level

CW2000 is still not collecting, do I need the SNMP-server engineID remote command? And if so, do you know the syntax?

Is there a way to see if CW2000 is trying and the switch is refusing?

No, you do not need to configure the remote engineID. You can use a sniffer trace to see if LMS is properly querying the switch.
