Information About RADIUS Change-of-Authorization
RADIUS Change of Authorization
The RADIUS Change of Authorization (CoA) provides a mechanism to change the attributes of an
authentication, authorization, and accounting (AAA) session after it is authenticated. When a policy changes

as a Cisco Secure Access Control Server (ACS) to reinitialize authentication and apply the new policy. This
