Hello. I am having difficulty with RADIUS COA (change of authorization) messages. Using a NAC platform (not Clearpass) and Radius is working to accept/deny and to assign vlan, but if the vlan assignment changes after the initial authentication, and a COA message is sent to the InstantOn switch, there is NO response. No deny, not even a single packet returned. Is there some additional configuration needed to allow this function?
