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
Joining IGMP 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>
