Iam using 4402-Controller and 1252 Access Points. The AP's are registered on the Controller and get an ip address but the laptops are not getting an ip address. The FWSM on the Core switch is configured as DHCP server with IP of 192.168.5.1. The 4402 WLC Mgmt-Interface also has the gateway of 192.168.5.1. The Mgmt-Interface IP is 192.168.5.5/24.
The AP-manager Interface IP is 192.168.5.6/24 with gateway of 192.168.5.1.
The FWSM debug messages says that the DHCP request has been discarded from the DHCP Relay Agent of WLC.
