Hello,
I've been working on a client disconnect issue with Aruba TAC for a few weeks now. I notified them of some findings i found today while looking at our DHCP server which is Infoblox.
While troubleshooting with a client as this user roamed around a hospital wing I noticed his device was sending DHCPREQUEST and DHCPACK's between the DHCP server. I compared it to another user who was stationary and connected to 1 access point. I then had a 3rd user try the same thing and noticed a similar pattern. As he roamed around it seemed like his machine was constantly sending DHCPREQUEST and DHCPACKs
Is this a normal pattern for Wireless roaming. These users are reamaining within the same SSID,Subnet and Wireless controller. I assumed that once the Device received it's DHCP address it would keep the address as long as it was staying connected and would only ask for an IP when the client came back online and sends a DHCPDISCOVER.
