A network engineer is troubleshooting a LAP that is unable to join the controller and receives the
message below:
LWAPP_CLIENT_ERROR_DEBUG. No more AP manager IP addresses remain
What does the log indicate?
A.
Two or more LAPs have the same IP address.
B.
An AP manager has the same IP address as another AP manager.
C.
A LAP has the same IP address as the AP manager.
D.
Two or more controllers have the same IP address.
same – manager
===================================================
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 to join 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 join the 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. _I
In order to troubleshoot this issue, ping the 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.
