encryption key configured in the switch (by using the

tacacs-server

key command). Verify the key in the server and compare it to the key
configured in the switch. (Use

show tacacs-server to list the global key.

Use

show config

or

show config running

to list any server-specific keys.)

The accessible TACACS+ servers are not configured to provide
service to the switch.

account.

exceeded
