CHAPTER 11
Static Multicast Forward Setup
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. You can configure this in the Advanced Application > Multicast > Multicast
Setting screen (see Section 25.2.1 on page 190). Figure 51 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 52 shows frames being forwarded to devices connected to port 3.
Figure 53 shows frames being forwarded to ports 2 and 3 within VLAN group 4.
