Cisco Cisco 2106 Wireless LAN Controller Release Notes

Reliable Link Layer, Secondary Backhaul 
Radio–A secondary backhaul radio is used 
as a temporary path for traffic that cannot be 
sent on the primary backhaul because of 
intermittent interference.

–

X

Passive Beaconing–Log messages from an 
access point that cannot connect are relayed 
through other access points to the controller.

X

X

Ethernet Bridging–Traffic is bridged from 
hosts connected to a wired port.

Containment of Bridged Multicast 
Traffic–There are two types of multicast 
traffic, bridged and LWAPP, and each is 
governed by a different mechanism. LWAPP 
multicast is managed by the LWAPP 
methods at the controller, and bridged 
multicast is governed by the multicast 
network settings. Multicast flows (such as 
video camera broadcasts) originating in the 
network from a MAP Ethernet port 
terminate only at the RAP Ethernet (In mode 
Multicast). In this mode, multicast flows are 
not transmitted throughout the mesh 
network, thereby reducing bandwidth 
requirements.

X

X

Universal Access–Radio used for backhaul 
traffic provides access for client traffic.

This feature is only configurable on 
the 1510. On the 1505, this feature is 
always enabled because the 1505 
only supports one radio (802.11b/g).

X

X

Support for Workgroup Bridges–Allows 
multiple wired hosts to connect to the 
wireless network through a workgroup 
bridge.

X

X

Multiple Queues for Backhaul 
Traffic–Extends client traffic prioritization 
to the backhaul traffic.
