DHCP assignment for Guest Access

Unanswered Question
Jun 9th, 2008

Hi Guys

I have come accross a unique problem with a 4402 controller, runnning software version 4.1.171 and 4.1.185, I have two profiles configured one for Corporate access and the second for Guest users.

The corporate users works ok, with clients receiving an IP address from the MS DHCP server.

However my main issue is that the guest users are not receiving an IP address from the MS DHCP server. I have checked the routing between the guest Vlan and the mgt vlan and all is ok, when I plug a wired machine into the guest VLAN it gets an IP address striaght away.

Does anyone know of a known bug with this software version 4.1.171 and 4.1.185, currently as a work around I have had to revert to using the internal DHCP. Unfortunately the customer whats all clients to us the Microsoft DHCP for manageability and single point of failure,

I really appreciate the help.

Many thanks

Disable dhcp by proxy on the controller.

config dhcp proxy disable

Sometimes clients have problems getting the dhcp response back when done by proxy on the WLC. The above command should help that.
