AP's cannot get IP from 4402's dhcp

I've installed a 4402 (using port1) into my existing ntwk. This 4402 is facing a 3550 which is aggregating traffic from 6 3524's. My AP 1121-g is plugged onto a port on one of the 3524's. This port has been assigned the associated vlan tag 601 (with switchport access config etc.). Both AP Mgr & Management Intfs.on my 4402 belong to this same vlan (601: subnet 192.168.37/28). I'm looking to use the internal dhcp of the 4402 so I have created another subnet (vlan:600 I'm able to ping the AP mgr intf. of my 4402 and ping my 3524 and 3550 switch (vlan intfs

:600 & 601) from my 4402 but the AP cannot pull an IP from the 4402 nor do i see the AP from the GUI of the 4402. Do I need the "ip helper-address" command and if so where? Because i have tried this and it still does not work. Please help!!!

Re: AP's cannot get IP from 4402's dhcp

Is the 1121 a new AP? I recently installed a couple APs but ran across a bug with the code shipped on the APs (CSCse02766; This prevented clients from getting DHCP addresses. I attempted to upgrade the code, which didn't help, but a downgrade corrected the problem. I'd have to power up my laptop to verify the code versions, but I think it shipped with 12.3(8) and I had to downgrade to 12.3(7) to get it to work.

Re: AP's cannot get IP from 4402's dhcp

I'm not sure what image is on the AP's however it's the AP's that are not getting IP's and not clients. In otherwords I have not even surpassed the 1'st level of getting the AP's to register w/the controller.
