> # Information About Role-Based Authorization

> Switches in the Cisco MDS 9000 Family perform authentication based on roles. Role-based authorization limits access to switch operations by assigning users to roles. This kind of authentication restricts you to management operations based on the roles to which you have been added.

> When you execute a command, perform command completion, or obtain context-sensitive help, the switch software allows the operation to progress if you have permission to access that command.
