1. The MLD snooping function in a VLAN will take effect when global MLD Snooping function is

enabled in 9.2.1 Snooping Config and the VLAN is created in Chapter 6 VLAN.

2. When the router port time or member port time is set for a VLAN, this value overrides the

value configured globally in 9.2.1 Snooping Config.

9.2.4 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 MLD 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→MLD Snooping→Multicast VLAN to load the following page.
