Parameter description:
IGMP snooping mode selection:
The switch supports three kinds of IGMP Snooping status, including
“Passive”, “Active” and “Disable”.
Disable:
Set “Disable” mode to disable IGMP Snooping function.
Default: Disable
Active:
In Active mode, IGMP snooping switch will periodically issue the
Membership Query message to all hosts attached to it and gather
the Membership report message to update the database of the
Multicast table. By the way, this also reduces the unnecessary
multicast traffic.

In Passive Snooping mode, the IGMP snooping will not periodically
poll the hosts in the groups. The switch will send a Membership
Query message to all hosts only when it has received a
Membership Query message from a router.
IP Address:
Show all multicast groups IP addresses that are registered on this device.
VLAN ID:
Show VLAN ID for each multicast group.
Member Port:
Show member ports that join each multicast group. Member port may be
only or more than one.
