Mesh APs doesn't associate to the WLC
is one of the most common issues seen in the Mesh
deployment. Complete this check:
Check that the MAC Address of the access point is added in the Mac Filter list in the WLC. This can be seen
in Security > Mac Filtering.
in Security > Mac Filtering.
Until MAP is connected to WLC, you cannot check state of AWPP without console access on MAP.
If you know an expected parent, based on Bridge Group Name, or geography, you can log into parent through
WLC, and issue some show and debug commands in order to see if child MAP attempts to connect.

This MAP is in
Maint
state, which indicates it has found a parent, and is in the desired AWPP or
Mesh State. The parent is AP ending with MAC db98.
•
Another way to check is if there is a parent entry in the Mesh adjacency table, issue the show mesh
adjacency parent command.

Check for IP AddressThe IP Address indicates if the Key Exchange between this AP and Parent AP was
successful. If there is no IP address, check the DHCP server. If only this MAP is not able to obtain an IP
address, but others are, this can be the key issue.
