WLC and Air 1231G

I have a 4402 WLC configured on the management VLAN and 9 AP's that were converted to LWAPP. When the AP's attempt to connect to the WLC, they download the image then display the following error. "No more AP manager IP addresses remain." The AP's then reboot and go through the whole process again. It doesn't matter if I assign static IP's or set them to DHCP, the same error appears.

Re: WLC and Air 1231G

I tried both suggestions without success. The same thing continues to happen.

Looking at the logs, I see that APs are associating then immediately disassociating. If it helps here are 15 minutes or so of message logs from the WLC.

Re: WLC and Air 1231G

Thank you. It was a duplicate IP address. *sigh*

One of the reasons for this error message is when there is a duplicate IP address on the network that matches the AP manager IP address. In such a case, the LAP keeps power cycling and cannot join the controller.

Re: WLC and Air 1231G

Error Message %LWAPP-3-HDR_ENCAP_ERR: Unable to encapsulate LWAPP header for [chars]; AP [hex]:[hex]:[hex]:[hex]:[hex]:[hex]

Explanation Could not send the LWAPP packet due to an internal error in encapsulating the packet. AP may not function as expected.

Recommended Action Copy the message exactly as it appears on the console or in the system log.
