Setting the Retransmission Limit
The retransmit parameter specifies how many times the RUCKUS device will resend an authentication request when the TACACS/TACACS+ server does not respond. The retransmit limit can be from 1 through 5 times. The default is 3 times.
To set the TACACS and TACACS+ retransmit limit, enter a command such as the following.
device(config)# tacacs-server retransmit 5
