4.5.6 IGMP snooping
IGMP snooping helps reduce the multicast traffics 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 enabled on the
switch. When globally enabled or disabled, it is also enabled or disabled in
all existing VLAN interfaces.
If global snooping is disabled, you cannot enable VLAN snooping. If global
snooping is enabled, you can enable or disable VLAN snooping.
