The Multicast Forwarding Table window displays the following parameters:
VLAN ID — VLAN identifier which uniquely identifies the VLAN to which a frame belongs, and for which this entry contains information on Multicast group MAC addresses.
MAC Address — The destination Group MAC address in a frame to which this entry filtering information applies.
Egress Ports — The complete set of ports in this VLAN, to which frames destined for this group MAC address are being explicitly forwarded. This does not include ports for which this address is only implicitly forwarded. These ports are configured through SNMP.
Learnt — The subset of ports listed in the in Group Egress Ports list which were learnt by the IGMP Snooping dynamic mechanism into this Multicast Filtering database.
