on the VLAN
Caution:
Although both Layer 2 and Layer 3 multicast protocols can run on the same switch
simultaneously, they cannot run simultaneously on a VLAN or its corresponding
VLAN interface.
Before configuring IGMP Snooping in VLAN view, you must enable IGMP Snooping
globally in system view. Otherwise, the IGMP Snooping feature cannot be enabled
in VLAN view.

2.2.2 Configuring Timers

This configuration task is to manually configure the aging timer of the router port, the
aging timer of the multicast member ports, and the query response timer.
If the switch receives no general IGMP query message from a router within the
aging time of the router port, the switch removes the router port from the port
member lists of all MAC multicast groups.
If the switch receives no IGMP host report message, it sends an IGMP
group-specific query packet to the port and enable the query response timer of the
IP multicast group.
If the switch receives no IGMP host report message within the aging time of the
member port, it sends IGMP group-specific query to the port and enables the
query response timer of the IP multicast group.
