 for the minimum LinkSNR required 
by data rate to maintain a link. See 
 fo
supporting LinkSNR calculation details.
The following diagnostic information is 
available: 
Controller CLI (show mesh path).
Controller GUI (Wireless > Access Points 
> All APs > AP Name > Neighbor Info 
(drop
-down menu) > Link Test 
(drop-down menu option for parent and 
child APs).
Cisco WCS (Reports > Mesh Reports

Check the status of the following parameters:

- LWAPP uptime
- Join Date and Time

2) If a poletop installation, verify if:
a) Power is bank-switched.

A bridge group name (BGN) is configured for 
the RAP but not for the MAPs.

Note
MAPs connect only to a controller 
with a default BGN.
