Are you using virtual gateway? I am trying to understand how you could have 3 CAS server on the same L2 segment (same SSID) without introducing a spanning tree loop. Typically you would run a CAS pair in HA and point the accounting server to the trusted interface VIP to handle HA, as far as 3 different servers, if they are on seperate vlans, then you will have seperate SSIDs which you can assign each SSID its own primary accounting server which the clients agent traffic will be switched to.
