7.7.6 IGMP Snooping
IGMP Snooping helps reduce the multicast traffic on the network by allowing the IGMP
snooping function to be turned on or off.
The first part provides the following settings,
Enable IGMP Snooping: Globally enable IGMP snooping in all existing VLAN
interfaces. By default, IGMP snooping is globally disabled on the switch. When
globally enabled or disabled, it is also enabled or disabled in all existing VLAN
interfaces.
If global snooping is disabled, the user cannot enable VLAN snooping. If global
snooping is enabled, the user can enable or disable VLAN snooping.
Last Member Query Interval: Without Immediate Leave, when the switch receives
an IGMP leave message from a subscriber on a receiver port, it sends out an IGMP
query on that port and waits for IGMP group membership reports. If no reports are
received in a configured time period, the receiver port is removed from multicast
group membership.
The second part provides the following settings:
Status: If global snooping is enabled, the user can enable or disable VLAN snooping.
