A static member interface does not respond to queries that the IGMP querier sends. When you

configure an interface as a static member or cancel this configuration on the interface, the interface
does not send any IGMP report or IGMP leave message without a request. This is because the

interface is not a real member of the multicast group or the multicast source and group.

Configuration procedure

To configure an interface as a static member interface:

Step

Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter interface view.

interface interface-type
interface-number

N/A

3.

Configure the interface as a
static member interface.

igmp static-group group-address
[ source source-address ]

By default, an interface is not a
static member of any multicast
group or multicast source and

group.

Configuring a multicast group filter

To restrict the hosts on the network attached to an interface from joining certain multicast groups, you can

specify an ACL on the interface as a packet filter so that the interface maintains only the multicast groups

that match the criteria.
To configure a multicast group filter:

Step

Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter interface view.

interface interface-type
interface-number

N/A

3.

Configure a multicast group
filter.

igmp group-policy acl-number
[ version-number ]

By default, no multicast group filter
is configured on any interface.
Hosts attached to an interface can

join any multicast group.

NOTE:

If you configure the interface as a static member interface for a multicast group or a multicast source and
group, this configuration is not effective for the multicast group or the multicast source and group.

Adjusting IGMP performance

Before adjusting IGMP performance, complete the following tasks:

Configure any unicast routing protocol so that all devices are interoperable at the network layer.

Configure basic IGMP functions.
