CHAPTER 11
Static Multicast Forwarding
Use these screens to configure static Multicast address forwarding.
11.1 Static Multicast Forwarding Overview
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. Figure 49 shows such unknown multicast frames flooded to all ports.
With static multicast forwarding, you can forward these multicasts to port(s) within a VLAN
group. Figure 50 shows frames being forwarded to devices connected to port 3. Figure 51
shows frames being forwarded to ports 2 and 3 within VLAN group 4.
