IAP215 cluster - clients stop getting an ip address

I have some issues reported by a customer that when they move locations they are unable to reconnect and/or get an ip address.


29 x IAP215 -


I have checked a couple of times when it was reported and there were 2-3 APs where none of the clients had a valid ip address and only 169.254.  Each occassion was different APs.  Rebooting the AP seem to resolve it and any client connecting to it gets a proper ip address.


At one point during the issue I was able to do a pkt-dump on dhcp and what I could see was the client requesting an ip address and the server responding.  Unfortunately I could not verify the response was going back to the device over the wifi.


  • port config on all aps checked and fine.
  • helper address setup on switch
  • address pool is nowhere near exhaustion.
  • dhcp server is receiving the requests and responding

I will raise a TAC case for this as it is pointing to something up with the APs, but wondering if anyone has had similar issues.

If my post is helpful please give kudos, or mark as solved if it answers your post.
