The priority determines the order in which the TACACS+ servers are contacted when 
attempting to authenticate a user. A value of 0 is the highest priority.
4.  (Optionally) In the Port field, specify the authentication port value for TACAS+ server 
sessions. 
If you do not specify a value, the switch uses the standard TCP port 49 for sessions with 
the server.
5.  In the Key String field, specify the authentication and encryption key for TACACS+ 
communications between the switch and the TACACS+ server. 
This key must match the encryption used on the TACACS+ server. The valid range is 
0–128 characters.
6.  (Optionally) In the Connection Timeout field, specify the amount of time that passes before 
the connection between the device and the TACACS+ server times out. 
If you do not specify a value, the switch uses a default value of 5.
