Access Point Disappears
This section summarizes possible reasons why an access point might disappear from a mesh network.
When an access point disappears, it is not viewable from the controller GUI or CLI 60 seconds after 
its disappearance.
On Cisco WCS, the icon remains on the map display until the next polling period (default of 15 
minutes) but is not available (greyed out). Limited historical information is available during this 
time.
 
A bridge group name (BGN) is configured for 
the RAP but not for MAPs.
1) Assign a BGN to the MAP.
Note
MAPs will only connect to a 
controller with a default BGN.
A bridge group name mismatch exists 
between a RAP and a MAP.
1) Reconfigure the MAP bridge group name 
to match the BGN of the appropriate RAP.
Note
You have up to 30 minutes to make 
this adjustment before the RAP 
reboots.
Controller has defaulted to the manufacturing 
time setting or is not set correctly causing the 
certification to fail.
1) Set correct time on the controller by 
entering the following commands:
config time manual mm/dd/yy
config time timezone delta-hours 
(delta-hours = difference in current time 
in hours from the universal coordinated 
time)
2) Configure the NTP server.

RAP admin status was disabled then 
re-enabled.
1) Wait several minutes for MAPs to 
reassociate with the controller.
Note
MAPs ignore admin status enable and 
disable.
Parent of access point has rebooted.
1) Wait the approximate times specified in 
.
Access point has excluded its parent.
1) To check for parent exclusion, look for the 
ciscoLwappMeshChildExcludedParent 
SNMP trap and the following Cisco WCS 
message: “Parent AP being excluded by child 
AP due to failed authentication, AP current 
parent MAC address "{yy.yy.yy.yy.yy.yy},” 
previous parent MAC address 
"{xx.xx.xx.xx.xx.xx}.”
