Hello Dear

i configure DHCP on the same switch to provide ip for the LAP , but the LAP can't get an ip address and can't joint the controller.

Hi Ali,

There is no configuration mode for Light Weight Access Points.

The AP should get the ip address from dhcp scope inorder to register with controller.

So first we will have to troubleshoot the dhcp issue.

Could you please provide the running configuration of L3 switch where the dhcp is running and highlight on which port the AP and WLC is connected?

Regards

Najaf

Can you at least plug a pc to that same vlan or port and get an IP address.

Exactly what firmware is your 2500 running? It should be running at least 7.0.X.

Ok. So can you console into the WAP and reboot? Post the entire bootup process of the WAP.
