IGMP enables hosts to inform routers when they join or leave groups.
Routers periodically query hosts (query interval) for the groups in which the
hosts are members. When there is more than one router in a broadcast
domain (subnet), one of the routers becomes the designated querier. Only
the designated router queries the hosts.
Both IGMP Version 1.0 and IGMP Version 2.0 are supported. After
selecting the specific IGMP version for an interface, you can manually
configure the Version 1.0 querier. The selection of the querier for Version
2.0 is dynamic but can be overridden.
Configuring IGMP includes enabling IGMP and the MTRACE globally on
the switch. You can do this from either the Web Agent or the CLI.
