5 - TAC Timeout
This parameter specifies the maximum amount of time the switch waits
for a response from a TACACS+ server before assuming the server
will not respond. If the timeout expires and the server has not
responded, the switch queries the next TACACS+ server in the list. If
there are not any more servers, the switch defaults to the standard
Manager and Operator accounts. The default is 10 seconds. The
range is 1 to 60 seconds.
