Hi,
I am running 2 Aruba 3600 Controllers that are constantly giving out conflicting IP addresses. DHCP is handled by Windows server and we operate a school environment with shared laptops for students and 802.1x authentication.
At various times throughout the day I will get laptops handed back to me that show as connected and get a valid IP address from DHCP, but are not actively connected past that.
Logging into the Aruba controller and going to Monitoring > All WLAN Clients and doing a search for the IP address will show an old client in the table.
Is there any way to ensure that these old clients are flushed out as soon as they are disconnected?
