Could not discover WLC using DHCP IP. Renewing DHCP IP.

Hi all,

I have a WLC model 2504 with 20 Cisco aironet 700 series.

The LAPs on the same subnet as the management interface of the controller.

It seems that all WCL settings are correct.

The problem is thate LAPs Not Joining to the Wireless LAN Controller. The CLI

displays the following error: 

Could not discover WLC using DHCP IP. Renewing DHCP IP.

Troubleshoot tested:

1.

The LAPs on the same subnet as the management interface of the controller. LAPs getting ip address from PaloAlto sub interface DHCP.

2. WLC time is correct.

3.

pinging the AP from the controller is OK.

Thanks:)
