Hello all,
We have a requirement for our WGB attached clients to receive regular broadcasts across the mesh. Based on my current configuration this doesn't appear to be working. I have no idea why this isn't working.
My mesh is based around 1552E Mesh Access Points, and a 5508 Controller running 7.0.220.0 software
The Work Group Bridges are Autonomous Cisco 1261 APs running 12.4(25d)JA1, attached to a Moxa L2 switch
To complicate matters, the AP and switch are in a network management VLAN (the same as the controller management interface), and the client device is in a seperate VLAN.
There are no problems with unicast traffic to and from the client device. It is registered correctly on the controller against the right VLAN / controller interface. I know the broadcasts are present in the VLAN on the LAN side, however they are not received by the client device.
I have enabled Ethernet Broadcast on the controller, in unicast mode (all multicast modes are default)
I have tried the Work group bridges in both infrastructure-client and normal client mode
Can anyone suggest any tests I can confirm to try and track the problem to either the controller or the WGB?
Thanks,
Michael

Try enabling multicast globally on the controller:
> config network multicast global enable

Regretably enabling multicast globally hasn't helped.
Is it expected that the CPU wouldn't receive the broadcast packets? I have performed a debug packet, with the source address of the broadcast as a filter, but don't get any hits. I am certain the packets are being flooded on the LAN.

I am assuming you were referring to the Multicast Containment? I have tried it int in-out and regular mode, to no avail. I got the impression it was more dealing with bridged traffic between the MAPs themselves?
Would it matter that I am using a static interface (the management interface) for the WGB itself, and a dynamic interface for the end host?

Hi Friend!
Did you get any feedback to this? Im facing a similar issue with a Mesh Network (1552E) and AP 1262 as a WGB. The clients behind WGB dont recieve multicas/broadcast traffic in any VLAN 802.1q, but the native vlan.
