SSID client not getting IP from Local DHCP scope.

[Cheah Lit Thor]

Hi,

i have a wireless controller 3504 with multiple SSID and all SSID unable to get the ip address from the WLC Local DHCP server.

Attach is the debug client XXX output.

But some how after idle some time the laptop able to join the SSID and get the ip address automatically and i found it has no problem to mobile phone to join ssid and get ip address, just only windows based laptop/pc have this problem.

May i know anybody encounter this problem and how to solve it ?

Have you run the debug through Wireless Debug Analyzer (cisco.com) ?

I had a customer problem previously with corporate PCs having problems with DHCP renews after the IT dept pushed out a new Windows firewall policy.  They had accidentally blocked unicast DHCP packets

So it's just an idea - test with firewall disabled so that you can rule that out.

Hi,

I just found some one change the DHCP Server Pool Timer which may cause the not enough ip address, i tuned it almost 1 week and seem so far working fine.

still monitoring. Thanks to your advise and idea.

Thanks
