I have a Nexus 5000 that I set up to use tacacs (Ciscos ACS 5.2). When I try to logon on the error I receive is 3011 invalid tacacs+ request packet - possibly mismatched shared secrets. I obvious I plugged the wrong shared secret (more like typo). Now it won't let me log in locally (with local account).
I deleted the device for the Cisco ACS server and it is still trying to authenticate against the ACS server no matter what account I use. I have not tried to console in yet but is that my best bet to getting logged on and fixing the config.
