How to change rights for online users

The Change of Authorization (CoA) function means that you can dynamically change rights of users on the RADIUS server through AAA. CoA allows the administrator to change the rights of an authenticated user through RADIUS. For example, employees of an enterprise access the enterprise intranet through different ports. After they go online, the RADIUS server can deliver the specified VLAN ID to the employees using the RADIUS protocol, so that the employees belong the same VLAN.

The CoA function only applies to RADIUS authorization, and cannot be used through local or HWTACACS authorization.
