Can the AP ping the primary and/or secondary Management IP address of the WLC?

[cisco]

No,

Ping from AP to AP successfully

[Leo Laohoo]

Ping from AP to AP successfully

SO the AP can't ping either WLCs.  Here's your problem.

The AP should be connected to an access switch port.  The WLCs should be connected to a Dot1Q trunk.  Can you verify this?

[cisco]

yes

[grabonlee]

There is a lot of request for resolution of your WLC. I take it that your WLC is on layer 3 mode (CAPWAP). Can you confrim that there is a DNS entry in your domain controller for the WLC IP management IP address (not AP manager)?

[cisco]

Yes, DNS entry has been configured in WLC

[grabonlee]

Sorry, what do you by DNS entry created in WLC? Basically, you should a DHCP IP specified in the management interface config on the WLC. However, you should also create a DNS entry in the Domain controller. You would need to ask your Server Team to do that for you as I guess you're not a Server engineer. On your switch or router you should have a IP helper pointing to the DHCP server.

[Leo Laohoo]

Can you post the config of your switch connected to your AP and your WLC?

Please post the config of the WLC too.
