IGMP Snooping Querier Commands
The IGMP/MLD Snooping Querier is an extension to the IGMP/MLD
Snooping feature. IGMP/MLD Snooping Querier allows the switch to
simulate an IGMP/MLD router in a Layer 2-only network, thus removing the
need to have an IGMP/MLD Router to collect and refresh the multicast
group membership information. The querier function simulates a small
subset of the IGMP/MLD router functionality.
In a network with IP multicast routing, an IP multicast router acts as the
IGMP/MLD querier. However, if it is required that the IP-multicast traffic in
a VLAN be switched, the PowerConnect can be configured as an IGMP/MLD
querier. When IGMP/MLD Snooping Querier is enabled, the Querier sends
out periodic IGMP/MLD General Queries that trigger the Multicast
listeners/member to send their joins so as to receive the Multicast data traffic.
IGMP/MLD Snooping listens to these reports to establish the appropriate L2
forwarding table entries.
The PowerConnect supports version IGMP V1 and 2 for snooping IGMP
queries.
