Release Notes for Cisco Aironet Access Points and Bridges for Cisco IOS Release 15.2(2)JA

OL-23990-01

Installation Notes

• Roaming improvements (for client workgroup bridges):

–

This release improves the reliability of fast roaming on workgroup bridges by allowing the unit

an additional retry when it needs to reassociate to the root access point.

–

This release also improves the method that workgroup bridges use to select the “best parent”

access point. Workgroup bridges can share association histories with rot access points, which

can build and share a list of best root access points among workgroup bridges. This method

improves helps workgroup bridges select the best root access point when roaming.

• VideoStream support on workgroup bridges (when used as a client): VideoStream improves the

reliability of an IP multicast stream by converting the multicast frame, over the air, to a unicast

frame. VideoStream was not supported for workgroup bridge clients in previous releases because a

workgroup bridge’s wired clients cannot be added to the controller (WLC) multicast table. In this

release, the workgroup bridge is added to the WLC multicast table, and the workgroup bridge

converts the VideoStream unicast frame into an Ethernet multicast frame and sends it out to its wired

clients.

Enter this command on the controller to enable VideoStream for workgroup bridges:

config media-stream wired-client enable
