2960S Stack, 15.0(2)SE3 & TACACS

[lekeosi11]

Hi

I upgraded a Cisco 2960s stack from 15.0(2)SE2 to 15.0(2)SE3 yesterday.

The switch stack is set to use TACACS for authentication.

Since then, I'm no longer able loging to the switch using ssh or http.

I start a SSH session, enter my username and immediatley I get Access Denied (3 times and the switch drops the connection).

I can't see any tacacs packets being sent from the switch to the ACS server.

The release notes for 15.0(2)SE3 do not indicate any issues with Tacacs.

Any ideas?

Thanks

Steven,

Can I request if you can raise a TAC Case?  Let them identify the Bug ID and post it here.

We had an issue with 12.2(55)SE7 where the TPLUS process was maxing the CPU. Ended up being a bug with the legacy "single-connect" TACACS mode. Once we took out the single-connect config and rebooted the switch, CPU behaved as expected. Note that a reboot is required to bring the CPU utilization back to normal.
