About Catalyst 3850 Wireless Multicast

Hello

     i'm testing for catalyst 3850 wireless multicast, and i've tried several configurations but it's always fault. I took a pc with the wired as the multicast video source, and another pc as the receiver with wireless, the two pc in the same vlan, for example, vlan 10.  the followed is the detail configuration about 3850.

The C3850 software version is Version 03.03.03SE RELEASE SOFTWARE (fc2), and i've tried the Version 03.02.02SE, it's the same result. if the multicast not worked, i can't do the Videostream function demo next step.

if video multicast group is

if video multicast group is 239.100.1.1, then same group cannot be configured for AP mcast -mcast mode communication.

 

Try this:

config t

no ap capwap multicast 239.100.1.1

ap capwap multicast 239.10.10.10
