WLC4404 DHCP Proxy

Hello everybody...

How to disable dhcp proxy on controller and what is the impact of doing it in the middle?

We tried once by giving 'config dhcp proxy disable' command but seeing virtual ip again.(likely it gets back to proxy mode).

We also have ip helper address on the L3 interface.

We have only external dhcp servers configured..

Any help would be appreciated.

Try to remove it from the GUI. You can disable that as long as your not using the WLC as a dhcp server. Since you also have IP helpers already defined you should be fine.

Thanks for your reply. After removing proxy mode also if wlc keeps the Virtual IP as DHCP ip what could be the issue..?We need dhcp transactions transparant to the client.

Thanks in advance

Is the dhcp server on a different vlan? I would also try to remove the client as it might be the client with the stuck info. You usually don't have to reboot the WLC, but it seems like something is hanging and a reboot might just be what you need to do in the middle of the night.

Thanks,

Scott

what version of code are you running on the 4404? earlier code didn't act the same as 6.0/7.0 code does WRT proxy

How about wireless client reply to offer as it lacks routing to virtual IP? Running with 7.0.116.0 code..?
