NOTES:
l
Do not assign reserved multicast IP addresses to a DM NVX device for streaming. For
additional information, go to
https://www.iana.org/assignments/multicast-
addresses/multicast-addresses.txt
.
l
Multicast collision is a concern with IPv4. For example, multicast IPv4 addresses 224.8.7.6
and 229.136.7.6 translate to the same MAC address (01:00:5E:08:07:06).
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.
