Section IV: Security 651
If you will be specifying more than one TACACS+ server and if all
of the servers use the same encryption secret, you can answer No
to this prompt and enter the encryption secret using the TAC
Global Secret parameter.
However, if you are specifying only one TACACS+ server or if the
servers have difference encryption secrets, then respond with Yes
to this prompt. You will see:
Enter per-server secret [max 40 characters] ->
Use this prompt to enter the encryption secret for the TACACS+
server whose IP address you are specifying.
4 - TAC Server Order
Use this selection to indicate the order in which you want the
switch to query the TACACS+ servers for logon authentication. Of
course, you can skip this option if you specified only one IP
address. The default is 1, 2, and 3, in that order.
5 - TAC Global Secret
If all of the TACACS+ servers have the same encryption secret,
rather then entering the same secret when you enter the IP
addresses, you can use this option to enter the secret only once.
3 - TAC Timeout
This parameter specifies the maximum amount of time the switch
waits for a response from a TACACS+ server before assuming the
server is not responding. If the timeout expires and the server has
not responded, the switch queries the next TACACS+ server in the
list. If there are no more servers, the switch defaults to the
standard Manager and Operator accounts. The default is 30
seconds. The range is 1 to 300 seconds.
5. After you have finished configuring the parameters in the TACACS+
Client Configuration menu, type R to return to the Authentication
Configuration menu, shown in Figure 205 on page 648.
6. From the Authentication Configuration menu, type 1 to select Server-
based Authentication.
The following prompt is displayed:
Server Based User Authentication (E-Enabled,
D-Disabled) ->
7. Type E to enable server-based authentication on the switch.
8. The TACACS+ client software is now active on the switch.
9. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
