8.1.4 Multicast VLAN

In old multicast transmission mode, when users in different VLANs apply for join the same
multicast group, the multicast router will duplicate this multicast information and deliver each
VLAN owning a receiver one copy. This mode wastes a lot of bandwidth.
The problem above can be solved by configuring a multicast VLAN. By adding switch ports to the
multicast VLAN and enabling IGMP Snooping, you can make users in different VLANs share the
same multicast VLAN. This saves the bandwidth since multicast streams are transmitted only
within the multicast VLAN and also guarantees security because the multicast VLAN is isolated
from user VLANS.
Before configuring a multicast VLAN, you should firstly configure a VLAN as multicast VLAN and
add the corresponding ports to the VLAN on the 802.1Q VLAN page. If the multicast VLAN is
enabled, the multicast configuration for other VLANs on the VLAN Config page will be invalid, that
is, the multicast streams will be transmitted only within the multicast VLAN.
Choose the menu Multicast→IGMP Snooping→Multicast VLAN to load the following page.

Description
Snooping Required. Enable IGMP Snooping globally on the switch
and for
Snooping→Snooping Config and Port Config page.
multicast Optional. Configure the multicast parameters for VLANs on
Multicast→IGMP Snooping→VLAN Config page.
If a VLAN has no multicast parameters configuration, it
indicates the IGMP Snooping is not enabled in the VLAN,
thus the multicast data in the VLAN will be broadcasted.
