I have an implementation of Alcatel/Aruba wireless. We've been trying to manage out DHCP pool as it hits 90 precent quite often. We are seeing this strange behavior in that a single user within a short period of time is associating and disassociating and as such gets new IP address. The DHCP server is retaining the old IP as being active so does not redistribute for 30 minutes. The examples I list below show two to three IP addresses being given out from the same AP in a few minute period. We've seen IP address changes in less that 30 seconds on a regular basis.
This issue seem to occur in areas of good coverage as well as in marginal areas. Lan IP Address Association time Duration Avg. Speed *172.21.34.49, 172.21.52.16* * *11/10/16, 4:25 PM 2 minutes 122Mps *172.21.59.221, 172.21.45.117, * *172.21.52.217* * * 11/9/16, 11:57 AM 5 minutes DHCP server is from Infoblox Any thoughts.
