Information
By default, access to commands are determined by the user’s role (if defined) or by
the user’s privilege level. If the aaa authorization role-only command is
enabled, then only the user’s role is used.
Before you enable role-based only AAA authorization:
1. Locally define a system administrator user role.This will give you access to
login with full permissions even if network connectivity to remote
authentication servers is not available.
2. Configure login authentication on the console. This ensures that all users are
properly identified through authentication no matter the access point
3. Specify an authentication method (RADIUS, TACACS+, or Local).
4. Specify authorization method (RADIUS, TACACS+ or Local).
5. Verify the configuration has been applied to the console or VTY line.
