TACACS+ Server Configuration
Use the TACACS+ Server Configuration screen to configure up to five TACACS+ servers with
which the switch can communicate.
 To configure TACACS+ server:
1. Select Security > Management Security > TACACS+ > Server Configuration.
2. In the TACACS Server field, specify the IP address of the TACACS server.
3. In the Priority field, specify the priority for the TACAS+ server.
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.
7. Click the Apply button.
