Managing IGMP Interfaces

Joining IGMP Groups

IP M
ULTICAST
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.
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
1. Enter configuration mode for the
selected interface.
2. Join the group on the interface.
Command
interface <c/s/i>
ip igmp join-group <group-address>
