I have a smartzone 100 with a moderate quantity of R600 AP's. The smart zone is running 184.108.40.206.862. I have an HP A5500 as my core switch. I am seeing a large quantity of duplicate IP address errors showing up in the logs. The devices have the same MAC address 90% of the time. It appears the issue is when they roam from one AP to another it is triggering an ARP notification and it is causing minor flooding of my network at different times. Is there a quick setting I am overlooking?
