Igmp Snooping Configuration - Lenovo RackSwitch G8332 Command Reference Manual

IGMP Snooping Configuration

© Copyright Lenovo 2016
IGMP Snooping allows the switch to forward multicast traffic only to those ports
that request it. IGMP Snooping prevents multicast traffic from being flooded to all
ports. The switch learns which server hosts are interested in receiving multicast
traffic, and forwards it only to ports connected to those servers.
The following table describes the commands used to configure IGMP Snooping.
Table 305.
