Aruba OS 8.2 - IP conflict on



Ever since we upgraded our Aruba wireless controllers to OS 8.2 from 6.5, we have been getting complaints of IP conflicts from our wired windows users on the vlans that we tag to our controllers to (We only tag to a few wired vlans, so it's pretty obvious).  The IP listed as a conflict is on the windows computers, and their logs point back to the MAC address of our controllers.  Is this a known issue, or maybe we forgot to check a box somewhere to prevent this on our controllers?
