Примечания к выпуску для Cisco Cisco 2106 Wireless LAN Controller

You can install this software release on the following Cisco Wireless LAN controller platforms: 2106, 
4400 series, and Wireless Service Module (WiSM) for the Catalyst 6500 and 7600.

You must install release 4.1.190.5 or 4.1.191.24M to operate Cisco Aironet 1520 series access points 
in your mesh network. 

Release 4.2.x and earlier 4.1.x releases will not support 1520 series mesh access points.

A 1520 mesh access point operating with release 4.1.190.5 is only supported in the US and 
Canada. 

Release 4.1.191.24M provides international support for 1520s, 1240s, and 1130s and support 
for the UNI-2 band in the US.

If a 1520 mesh access point is operating in a network, and you downgrade the software release 
within your network to a non-mesh release, the 1520 will not reconnect and might become 
stranded.

If 1520s are going to be installed in a mesh network that is also operating with 1510s, then note the 
following:

The network must first be upgraded to a version of 4.1.190.5 or 4.1.191.24M.

All 1510s must be upgraded to the new mesh release and associated with the controller (joined) 
before any 1520s can be added to the network.

A 1520 should not be added to the network until release 4.1.190.5 or 4.1.191.24M is running on 
the network to ensure proper communication between 1510s and 1520s.

Mobility groups functionality is supported when operating with 4.1.190.5 or 4.1.191.24M and 
all 4.1.x versions of non-mesh controller software.

A 1510 can be a parent to a 1520 mesh access point in release 4.1.191.24M; however, in release 
4.1.190.5 the 1510 can only be a child to a 1520.

Upgrading to 4.1.191.24M provides full interoperability between 1510s and 1520s. Release 
4.1.190.5 does not provide full interoperability. Refer to the 

 for upgrade path specifics.

If you are operating with indoor and outdoor access points in your mesh network, then note the 
following:

Series 1130 and 1240 indoor access points can operate as mesh access points in this release.

All other indoor access points (excluding 1250) operate as standard, non-mesh access points.

Indoor access points 1130 and1240 configured as mesh access points (bridge mode) should not be 
connected to a controller without mesh release 4.1.191.24M installed. The1130 and 1240 mesh access 
points must be converted back to LWAPP (local mode) access points before they are connected to a 
controller with a non-mesh release. See the 

 for details on the conversion.
