Configure a TACACS+ Server on the Switch
Use the TACACS+ Server Configuration page to configure up to five TACACS+ servers with
which the switch can communicate.
 To configure a TACACS+ server on the switch:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch on page 13.
The login window opens.
4. Enter the switch’s password in the password field.
The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
5. Select Security > Management Security> TACACS+ > TACACS+ Server Configuration.
The TACACS+ Server Configuration page displays.
6. In the TACACS+ Server field, enter the TACACS+ server IP address.
7. In the Priority field, specify the priority for the TACACS+ 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. The valid range is
0–65535.
8. In the Port field, specify the authentication port value for TACAS+ server sessions. It must
be within the range 0–65535. If you do not specify a value, the switch uses the standard
TCP port 49 for sessions with the server.
