Configuration procedure:
CONFIGURATION PROCEDURE:
Step Operation Description
1 Enable IGMP Snooping Enable IGMP Snooping globally on the Switch and for the
Ports on
Multicast>>IGMP Snooping>>Snooping Config and
Port Config pages.
2 Configure the Multicast
parameters for VLANs Configure the Multicast parameters for VLANs on
Multicast>>IGMP Snooping>>VLAN Config page. If a VLAN
has no Multicast parameters configured it indicates IGMP
Snooping is not enabled in the VLAN, any Multicast Data in
the VLAN will be broadcasted.
8.1.4 Multicast VLAN
In the original implementation of Multicast, when users in different VLANs applied
to join the same Multicast group, the Multicast Router would duplicate the
Multicast Data and deliver each VLAN its own copy of the Data. This utilizes
large amounts of bandwidth.
This problem can be solved by configuring a Multicast VLAN. By adding Switch Ports to
the Multicast VLAN and enabling IGMP Snooping, you can allow client devices in differ-
ent VLANs to share the same Multicast VLAN. This preserves bandwidth since Multicast
streams are transmitted only within the Multicast VLAN and also adds security as the
Multicast VLAN is isolated from the other VLANs on the Switch.
