Colin -
Thanks for your note. Our RADIUS server records users moving about the network, presenting everything on our management console. This works great on our switches, we see the switchport / building / room, etc. On our controller-less access points from a competing vendor, we see which AP they're connected to. These particular APs do a single RADIUS authentication transaction, then OKC for roaming. But when a user roams, we get a RADIUS accounting transaction informing us of the roam. We use this to keep our database up-to-date.
Ideally, the Aruba controller would do a single RADIUS authentication request, then keep us updated with accounting transactions during roam events.
It doesn't seem like this is possible (unless I'm missing something here...). Is there some other notification that can be used to observe client roams? I suppose we could hack it together from an SNMP trap or something.
Thanks
Norman
