Function name: IGMP Snooping Status
Function Description: IGMP is used to snoop the status of IP multicast
groups and display its associated information in both tagged VLAN and
non-tagged VLAN networks. Enabling IGMP with either passive or active
mode, you can monitor the IGMP snooping information, which contains
the multicast member list with the multicast groups, VID and member
port.
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 Mul-
ticast table. By the way, this also reduces the unnecessary multicast
traffic.
Passive: In Passive Snooping mode, the IGMP snooping will not peri-
odically poll the hosts in the groups. The switch will send a Member-
ship Query message to all hosts only when it has received a
Membership Query message from a router.
IP Address: how all multicast groups IP addresses that are registered
on this device.
