How to set up IGMP snooping/IGMP filtering
Here, we only set up the IES-1248-51V to support IGMP snooping and IGMP
filtering. Please refer to the user guide of the Video Server and the subscriber device.
We assume the video server provides three channels, movie 1 on 240.10.10.8 group,
movie 2 on 240.10.10.9 group and movie 3 on 240.10.10.10 group. And we assume
the subscriber want to subscribe two channel, movie 1 and movie 2. If we don’t
enable the IGMP snooping, every one can see all movies. If we don’t set the IGMP
filtering on the port, the subscriber behind the port will receive all movies.
1. IES-1248-51V settings

while, you will see the number of

the query packet from IGMP router.
