Product Manual — Doc. 8918B
The following items provide recommendations for configuration of a network switch for IGMP
snooping:
l
Set the IGMP query interval to 60 seconds or 125 seconds. The recommended setting is the
default setting of the network switch.
l
For good network performance, ensure that there is only one IGMP querier in the network.
l
Set IGMP snooping to v2 or v3.
l
Enable IGMP snooping globally as well as for each specific VLAN for DM NVX connected
ports.
l
Configure the network switch to drop unknown multicast packets.
l
If the network switch supports IGMP fast leave, enable the configuration at the port,
global, or VLAN level.
l
If the network switch supports PIM snooping, enable the configuration to prevent flooding
IP multicast traffic toward multicast router (mrouter) ports.
