Do Cisco router 2811 and Catalyst 3750 support SNMPv3?

Hi,

Do Cisco router 2811, IOS 12.4(20)Ti, and Catalyst 3750, IOS 12.2.(53)SE, support SNMPv3?

Attached file contains my SNMPv3 configurations and "show snmp" results.  Would you please give me your advice?  Thanks.

Hi,

Yes, they do support SNMPv3. Are you getting any kind of error while configuraing SNMPv3 on this version ?

Many Thanks,

Gaganjeet

Hi Gaganjeet,

Thanks for the response.  No, I haven't seen any SNMPv3 error on the Cisco devices.  I'm trying to reduce the scope of my trouble shooting if I know my Cisco router and switch are not the problem.

Certainly both the 2811 and the 3750 do support SNMPv3. So support for the feature is not an issue in your situation.

I have looked at the config that you attached and believe that it looks reasonable. You have not told us about the SNMP server that will communicate with these devices. So we have no way to know if the details of the configuration are correct.

Have you attempted to discover these devices with an SNMP server that is configured to use SNMPv3 and has this user and passwords configured? If it does not work my first suggestion would be to check to verify that the passwords configured are exactly the same on the clients and on the server (and perhaps re-configure the passwords just to be sure). If the passwords are not a problem my second suggestion would be to check and verify that the authentication and encryption parameters match between the server and the clients.
