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 traffic is always forwarded, flooding the network.
IGMP Snooping
IGMP Snooping provides the ability to prune multicast traffic so that it travels only to those end destinations
that require that traffic, thereby reducing the amount of traffic on the Ethernet LAN.
NOTE
IGMP Snooping will be disabled when Port-Based VLAN is enabled.
