Role-Based Access Control Commands
With Role-Based Access Control (RBAC), access and authorization is controlled based on a user’s role. Users are granted
permissions based on their user roles, not on their individual user ID. User roles are created for job functions and through those roles
they acquire the permissions to perform their associated job function.
This section describes the syntax and usage of RBAC-specic commands. You can nd information on other related security

Usage Information
By default, access to commands are determined by the user’s role (if dened) 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 dene 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. Congure login authentication on the console. This ensures that all users are properly identied through
authentication no matter the access point
3. Specify an authentication method (RADIUS, TACACS+, or Local).
4. Specify authorization method (RADIUS, TACACS+ or Local).
