ProSafe 7000 Managed Switch Software Administration Manual, Release 8.0.3 IGMP Querier When the switch is used in network applications where video services such as IPTV, video streaming, and gaming are deployed, the video traffic would normally be flooded to all connected ports because such traffic packets usually have multicast Ethernet addresses. IGMP snooping can be enabled to create a multicast group to direct that traffic only to those users that require it. However, the IGMP snooping operation usually requires an extra network device-normally a router-that can generate an IGMP membership query and solicit interested nodes to respond. With the build-in IGMP Querier feature inside the switch, such an external device is no longer needed.

IGMP Snooping and Querier

v1.0, June 2010

IGMP Querier

When the switch is used in network applications where video services such as IPTV, video streaming, and

gaming are deployed, the video traffic would normally be flooded to all connected ports because such traffic

packets usually have multicast Ethernet addresses. IGMP snooping can be enabled to create a multicast

group to direct that traffic only to those users that require it.

However, the IGMP snooping operation usually requires an extra network device—normally a router—that

can generate an IGMP membership query and solicit interested nodes to respond. With the build-in IGMP

Querier feature inside the switch, such an external device is no longer needed.

Since the IGMP querier is designed to work with IGMP snooping, it is necessary to enable IGMP snooping

when using it.The following figure shows a network application for video streaming service using the IGMP

querier feature.
