Configuring System Authentication

You can configure the router to use RADIUS or TACACS+ authentication, or both, to validate users who attempt to access the router. If you set up both authentication methods, you also can configure which the router will try first.

When configuring system authentication, you can do the following:

• Configuring RADIUS Authentication
• Configuring TACACS+ Authentication
• Specifying a Source Address for RADIUS and TACACS+ Servers
• Configuring Template Accounts for RADIUS and TACACS+ Authentication
• Configuring the Authentication Order
