Important Notes for Controllers and Mesh Access Points
This section describes important information about controllers and mesh access points.
Access Point Support Limit on Cisco WiSMs
The Cisco WiSM supports only up to 300 mesh access points reliably. Therefore, do not allow more than
300 mesh access points to associate to a Cisco WiSM.

Bridge MAC Filter Config Status Shown in Error
The show network command mistakenly shows a status for the Bridge MAC Filter Config parameter.
This parameter is not a configurable option in software release 4.1.192.35M (CSCsk40572).

Limit Bridge Group Names to 11 Characters
Entering more than 11 characters into the bridge group name (BGN) field on the controller GUI mesh
access point configuration page generates an error message. An error also appears when you configure
this parameter through the config ap bridgegroupname set groupname Cisco_MAP CLI command or
WCS (CSCsk64812).

Monitoring Port LED Status on a 1520 Series Access Point
When you disconnect a cable from a 1520 series access point, the port LED associated with that
connection might remain lit for up to 3 seconds.

Data Rate Considerations in Short Link Deployments of 1520 Series Access
Points
Points
For dynamic frequency selection (DFS) bands, the current Hammer 5-GHz radio does not meet the
receiver saturation specification of –30 dBm for some of the higher data rate modes due to a transceiver
chipset optimization made to lower the DFS false detect probability. The typical receiver saturation input
level is –37 dBm at 24 and 36 Mbps. The receiver saturation performance impact can be mitigated by
reducing transmit power and antenna gain where possible. For typical deployments where radios are
separated by reasonable distances, there is no impact to high data rate support.
