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.
