Примечания к выпуску для Cisco Cisco 4404 Wireless LAN Controller

You can install this software release on the following Cisco Wireless LAN controller platforms: 2100 
series, 4400 series and Wireless Service Module (WiSM) for the Catalyst 6500.

Release 4.1.190.5 is the first standalone mesh release for controllers.

You must install Release 4.1.190.5 to operate AP1520s in your mesh network. Any release other 
than that release will not support an AP1520. 

If an AP1520 is already connected in the network, and you downgrade the software release 
within your network, the 1520 will not connect and might become stranded.

If the AP1520 is going to be installed in a mesh network that is also operating with AP1510s, note 
the following:

The network must first be upgraded to a version of 4.1.18x.x before upgrading to Release 
4.1.190.5.

The AP1520 should not be added to the network until Release 4.1.190.5 is running on the 
network to ensure proper communication between the AP1510 and AP1520.

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