Configuring TACACS+ Authentication (NSM Procedure)

To use TACACS+ authentication, you must configure at least one TACACS+ server. Configuring TACACS+ authentication involves identifying the TACACS+ server, specifying the secret (password) of the TACACS+ server, and setting the source address of the device's TACACS+ requests to the loopback address of the device.

To configure TACACS+ authentication:

1. In the NSM navigation tree, select Device Manager > Devices.
2. Click the Device Tree tab and then double-click the device for which you want to configure TACACS+ authentication.
3. Click the Configuration tab. In the configuration tree, select System > TACACS+ Server.
4. Add or modify TACACS+ settings as specified in Table 1.
5. Click one:
   • New—Adds a new TACACS+ server.
   • OK—Saves the changes.
   • Cancel—Cancels the modifications.
