To enable IGMP on the router or switch, use the command:

enable ip igmp

To enable IGMP on a specific interface, use the command:

enable ip igmp interface=interface

You can configure the IGMP proxy agent to monitor the reception of IGMP
general query messages on an interface, and to generate a log message and an
SNMP trap if an IGMP general query message is not received on the interface
within a specified time interval.

To enable monitoring on an interface and set the time interval, use the
command:

set ip igmp interface=interface

querytimeout={none|0|1..65535}

To display information about IGMP and the IGMP proxy agent, use the
command:

show ip igmp

IGMP filtering extended to all IGMP message types

IGMP filtering lets you manage the distribution of multicast services on each
switch port by controlling which multicast groups the hosts attached to a
switch port can join.

IGMP filtering is applied to multicast streams forwarded by IGMP, IGMP
Snooping, or MVR.

Filtering of IGMP membership reports was supported in a previous software
version. This software version adds support for filtering IGMP query, report
and leave messages.

To configure an IGMP filter, you must create the filter and then apply it to one
or more switch ports.

To do this, first create the filter, using the command:

create igmp filter=filter-id

Then add one or more entries to the filter, using the command:

add igmp filter=filter-id groupaddress={ipadd|ipadd-ipadd}

[msgtype={query|report|leave}] [action={include|exclude}]

[entry=1..65535]
