Configuring the Dead Timer

dead, before sending out a test packet to determine if the server is now alive.
The default dead timer value is 0 minutes. TACACS+ server monitoring is not performed if the dead
Note
timer interval is 0 minutes, unless the TACACS+ server is a part of a bigger group with the dead-time
interval greater than 0 minutes. (See
Note If the dead timer of a dead TACACS+ server expires before it is sent a TACACS+ test message, that
server is marked as alive again even if it is still not responding. To avoid this scenario, configure a test
