Enabling Multicast Filtering
Use the USB console or web interface to enable or disable IGMP Snooping and IGMP querying. If IGMP
Snooping is not enabled, then IP multicast traf f ic is always f orwarded, f looding the network.
IGMP Snooping
IGMP Snooping provides the ability to prune multicast traf fic so that it travels only to those end destinations
that require that traf f ic, thereby reducing the amount of traf f ic on the Ethernet LAN.
NOTE
IGMP Snooping will be disabled when Port-Based VLAN is enabled.
