11.1.2 Wha t Yo u Ne e d T o Kno w
A multicast MAC address is the MAC address of a member of a multicast group. A static multicast
address is a multicast MAC address that has been manually entered in the multicast table. Static
multicast addresses do not age out. Static multicast forwarding allows you (the administrator) to forward
multicast frames to a member without the member having to join the group first.
If a multicast group has no members, then the switch will either flood the multicast frames to all ports or
drop them.
multicast forwarding, you can forward these multicasts to ports within a VLAN group.

frames being forwarded to ports 2 and 3 within VLAN group 4.
