Multicast Filtering
Hi,
I am trying to separate two multicast streams, one being data and the other video. The video data must be prevented from flooding the data network, which has some old switches that always broadcast all multicast packets.
Topology is Data/Video source host - GS108 - M4100-D12G - Broadcast switch - Data user
Data is multicast on 239.0.0.1
Video is multicast on 239.254.0.10
Video is sent to the user via a the GS108 unmanaged switch, so it could be blocked at input to the M4100.
There are no routers on the network to manage the IGMP, so not sure that IGMP snooping will work.
Any suggestions?
Thanks

Hi mickmck,
Welcome to the community!
Netgear Managed Switches support Multicast Filtering via MAC filter, but it only support filtering multicast by destination MAC, not support filtering by IP address.
So if you want to only transmit specific multicast packet on the port(ie. 239.0.0.1, you should covert the IP address to multicast MAC as 00:01:5E:00:00:01), then create MAC filter with this MAC address in Destination Port Members. Others multicast packet will be lost in this port.
For MAC Filter configuration, please refer to page 311 of below link: http://www.downloads.netgear.com/files/GDC/M4100/M4100_UM_2apr15.pdf
Thanks,
Eric
NETGEAR EmployeeThanks EricZ.
Turns out that Security > Traffic Control > MAC Filter > MAC Filter Configuration was where we needed to limit the 239.255.0.10 traffic to a single port. Of course this means that the other MAC addresses with the same prefix will be limited but this does not affect our application.
cheers

could you elaborate what you need to seperate mutlicast packets on M4100?
If you just don't want vedio packets flood in entire network, you can use igmpsnooping on M4100.
