50-7 config igmp_snooping multicast_vlan_group
Description
This command is used to configure the multicast group learned with the specific multicast VLAN.
The following cases can be considered for examples:
Case 0- If the IGMP Snooping is enabled on the VLAN of the join packet, the multicast VLAN won't
process the packet.
Case 1- The multicast group is not configured, multicast VLANs do not have any member ports
overlapping and the join packet received by the member port is learned on only the multicast
VLAN that this port is a member of.
Case 2- The join packet is learned with the multicast VLAN that contains the destination multicast
group. If the destination multicast group of the join packet cannot be classified into any multicast
VLAN to which this port belongs, it will be forwarded or dropped according to forward unmatched
mode.
Note that a profile cannot overlap in different multicast VLANs. Multiple profiles can be added to a
multicast VLAN.
