  • 1.  Radius COA problems

    Posted 10-25-2023 01:00 PM

    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?
