Hello,

Most likely you have configured AAA command authorization and the switch is

not able to communicate with the AAA server. Please perform password

recovery procedure and then remove the corresponding AAA configurations.

Once you check and make sure that the AAA server is working correctly (if

you are intending to use AAA command authorization), put the AAA commands

back in there.
