Setting up IGMP snooping/IGMP filtering

In this section, we will show you how to configure IGMP snooping and filtering on

the IES-5000. For details on configuring a video server and the corresponding

subscriber device, refer to the documentation that comes with the devices.

For this application example, the video server provides three channels:

movie 1 in the 240.10.10.8 multicast group

movie 2 in the 240.10.10.9 multicast group

movie 3 in the 240.10.10.10 multicast group

If IGMP snooping is not enabled or if IGMP filtering is not enabled on the ports, all

subscribers can watch movies from each channel. We want to limit a subscriber to

view movies from movie channels 1 and 2 only.

1. IES-5000 settings

1.1 Activating IGMP Snooping

Enable IGMP Snooping on the IES-5000.

CI command:

TGE1> multicast igmp enable snooping

1.2 Setting up IGMP Filtering

Next enable IGMP filtering and configure IGMP filtering profiles for a subscriber to

limit the movie channels the subscriber can watch.

For this example, we want to allow the subscriber to join the movie 1 and movie 2

groups. This means that traffic from the 240.10.10.8 and 240.10.10.9 multicast groups

are sent to the port to which the subscriber is connected.

On the IES-5000, create an IGMP filter profile (Subscriber1) and apply the profile to

port 1. Then apply the profile to the subscriber port (7-1). Save the settings to make it

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
