Explanation:
This is another common issue that is seen when the AP tries to join the WLC. You might see this error message when the AP tries tojoin the controller.
No more AP manager IP addresses remain
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 jointhe controller.
The debugs will show that the WLC receives LWAPP discovery requests from the APs and transmits a LWAPP discovery response to the APs.
However, WLCs do not receive LWAPP join requests from the APs.
In order to troubleshoot this issue, pingthe AP manager from a wired host on the same IP subnet as the AP manager. Then, check the ARP cache. If a duplicate IP address is found, remove the device with the duplicate IP address or change the IP address on the device so that it has a unique IP address on the network.
The AP can then join the WLC.
