We have not configured anything wrong, the same config with a downgraded IOS and we do not have this problem anymore.They are sitting with 100% CPU currently, this is a bug, not incorrect config.Also Simen seems to have seen the issue on 2960 as well...

I have a couple here now with dead SSH, pushing some config to remove TACACS via SNMP, then a reboot will bring them back.

Hi allWe are seeing the same behaviour on 2960S, 12.2(55)SE7.Also "C3560 Software (C3560-IPBASEK9-M), Version 12.2(55)SE8" may also be affected.
