The fields that can be configured in Multicast VLAN Global Settings are described below: 
Parameter  Description 
Multicast VLAN IPv4 State 
Select to enable or disable the IPv4 IGMP control packet process in multicast 
VLANs. 
Forward Unmatched 
Select the enable or disable the Forward Unmatched feature here. This specifies 
that if the received IGMP or MLD control packet is untagged, does not match any 
profile, and the associated default VLAN is a multicast VLAN, or is tagged with a 
multicast VLAN, but does not match the associated profile, then the packet will be 
forwarded or dropped based on this setting. By default, the packet will be 
dropped. 
Multicast VLAN IPv6 State 
Select to enable or disable the IPv6 MLD control packet process in multicast 
VLANs. 
Ignore VLAN 
Select the enable or disable the ignore VLAN feature here. This specifies the 
setting for tagged IGMP or MLD control packets. If enabled, then the packet’s 
VLAN is ignored and taken to match the profile to find its multicast VLAN. When 
this option is enabled, the Switch will ignore the VLAN of the receiving IGMP or 
MLD control packet and try to find a match profile. 
VID 
Enter the VLAN ID of the multicast VLAN that will be created or deleted here. The 
range is 2 to 4094. 
VLAN Name 
Enter the VLAN name of the multicast VLAN that will be created or deleted here.
