ADC 3 Managing IGMP Interfaces

356 CHAPTER 17: MANAGING IP MULTICAST

In the Cuda 12000, you can configure interfaces to proxy for individual IP

multicast addresses or multicast address ranges. This gives you a lot of

flexibility. For example, you can proxy for a single multicast group on one

interface and a different multicast group on another interface. Alternatively,

you could also include these groups in the same range and proxy for them

both on the same interface.

Managing IGMP Interfaces

Perform the following tasks to manage IGMP interfaces:

■Join groups

■Configure IGMP interface parameters

■Display groups and parameters

■Delete groups

An interface on a Cuda 12000 can join a multicast group in two ways:

■Manually, through the ip igmp join-group command

■Automatically, through the reception of IGMP reports from the network

There are no predefined multicast groups. You can configure up to 500

groups per chassis and up to 50 groups per DOCSIS module.

Use the following procedure to join a multicast group on an IP interface

manually:

Task Command

1. Enter configuration mode for the

selected interface.

interface <c/s/i>

2. Join the group on the interface. ip igmp join-group <group-address>
