1. The MLD snooping function in a VLAN will take effect when global MLD snooping function is
enabled in 8.2.1 Snooping Config
2. When the router port time or member port time is set for a VLAN, this value overrides the value
configured globally in

8.2.4 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.
Specify the forbidden router ports which is mainly used to forbid
ports becoming router ports.
