Query Interval Enter the number of seconds the VMG sends a query message to hosts to get the group
membership information.
Query Response Enter the maximum number of seconds the VMG can wait for receiving a General Query
Interval message. Multicast routers use general queries to learn which multicast groups have members.
Last Member Enter the maximum number of seconds the VMG can wait for receiving a response to a Group-

member remains in a specific multicast group.

Value network congestion.
Maximum Enter a number to limit the number of multicast groups an interface on the VMG is allowed to
Multicast join. Once a multicast member is registered in the specified number of multicast groups, any
Groups new IGMP or MLD join report frames are dropped by the interface.
