Hello Sims

RADIUS Change of Authorization is, according to Cisco, is a feature that:

…provides a mechanism to change the attributes of an authentication, authorization, and accounting (AAA) session after it is authenticated. When a policy changes for a user or user group in AAA, administrators can send the RADIUS CoA packets from the AAA server such as a Cisco Secure Access Control Server (ACS) to reinitialize authentication and apply the new policy.

You can find out more information about it at the following Cisco documentation:

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_usr_aaa/configuration/15-sy/sec-usr-aaa-15-sy-book/sec-rad-coa.html#:~:text=The%20RADIUS%20Change%20of%20Authorization,session%20after%20it%20is%20authenticated.

I hope this has been helpful!
