debug DHCP looping vWLC v8.3.110.0

[firestartest]

Client authenticates, obtains IP address. But from the vWLC CLI doing debug client I get a never ending stream of DHCP messages.

Is this a bug or config issue?

From the Windows client it gets an address straight away and stays connected.

Client gets 192.168.36.10

vWLC vlan interface 36 IP 192.168.36.2

Gateway is 192.168.36.254

vWLC management is 192.168.32.23

DHCP server 192.168.32.1

What is the RSSI of the client? 

By the way, I'd be upgrading the firmware of the controller before proceeding any further.

[firestartest]

RSSI is -34

Upgraded to 8.3.112.0 - same issue.

Client does not disconnect and can access network resources without any problem. But the WLC CLI still floods with DHCP messages.

[Leo Laohoo]

Ok, now is this happening to ALL the wireless clients or just happening to this one?

[firestartest]

It's happening to all clients.

Just ran wireshark off a few clients and it's showing a constant stream of source 1.1.1.1 to destination client IP DHCP ACK.

If I turn off DHCP proxy on WLC and use IP helper on SVI DHCP I don't get any errors. Soon as remove SVI ip helper and enable WLC DHCP proxy it starts flooding again.

Can't comment on DHCP Proxy as I don't use this feature.
