How to set up IGMP snooping/IGMP filtering

Here, we only set up the IES-5000 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-5000 settings

1.1 Enable IGMP Snooping

Enable IGMP Snooping to switch on the IGMP Snooping function.

CI command:

TGE1> multicast igmp enable snooping

1.2 Set up IGMP Filtering

If we don't set up IGMP filtering, the subscriber will receive all the movies. We set up

a IGMP filter Profile and apply it to specific port to limit the channels subscriber can

see.

In this case we only allow the subscriber to join movie 1 and movie 2. That means

only the groups 240.10.10.8 and 240.10.10.9 can be forwarded this subscribed port.

We create a IGMP Filter profile and apply the profile to port 1.Then, we select the

Subscriber1 in IGMP Filter Profile. And save the configurations letting the setting

to take effect.

CI command:

TGE1> profile igmpfilter set Subscriber1 1 224.10.10.8 224.10.10.9

TGE1> multicast igmpfilter set 7-1 Subscriber1

TGE1> config save
