Release Notes for Cisco Wireless LAN Controllers and Mesh Access Points for Release 4.1.192.35M
OL-31336-01
Important Notes
Access Point Support Limit on WiSMs
The WiSM only supports up to 300 mesh access points reliably. Therefore, do not allow more than 300
mesh access points to associate with a WiSM.
mesh access points to associate with a WiSM.
Configuration Database Setting of 2048 Recommended for Large Mesh Deployments
In large mesh deployments, increasing the configuration database setting to 2048 is highly
recommended. The configuration database total includes MAC filter entries, access point MIC and SSC
entries, dynamic interfaces, management users, and local net users. You can increase the configuration
database to 2048 using the config database size 2048 command and in the controller GUI, at the
following Security > AAA > General window (CSCsg88704).

Bridge MAC Filter Config Status Shown in Error
The show network command mistakenly displays a status for the Bridge MAC Filter Config parameter.
This parameter is not a configurable option in release 4.1.192.35M (CSCsk40572).
This parameter is not a configurable option in 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 in the controller GUI mesh
access point configuration window (Wireless > All APs > AP-Name > Mesh) generates an error
message. This is also true when assigning bridge group names for mesh access points in Cisco WCS
(Configure > Access Points > AP_name) and the config ap bridgegroupname set groupname
Cisco_MAP command (CSCsk64812).

Four Gigabit Ethernet Ports Supported on 1520s
The 1520 series access point supports four Gigabit Ethernet interfaces.
•
Port 0 (g0) is a Power over Ethernet input port–PoE (in)
•
Port 1 (g1) is a Power over Ethernet output port–PoE (out)
•
Port 2 (g2) is a cable connection
•
Port 3 (g3) is a fiber connection
You can query the status of these four interfaces in the controller CLI and Cisco WCS.
In the Controller CLI, the show mesh env summary command is used to display the status of the ports.
•
The Up or Down (Dn) status of the four ports is reported in the following format:
–
port0(PoE-in):port1(PoE-out):port2(cable):port3(fiber)
•
For example, rap1522.a3800 in the display below shows a port status of UpDnDnDn. This indicates
that:
that:
–
PoE-in port 0 (g0) is Up, PoE-out port 1 (g1) is Down (Dn), Cable port 2 (g2) is Down (Dn) and
Fiber port 3 (g3) is Down (Dn).
Fiber port 3 (g3) is Down (Dn).
