CHAPTER 11
Static Multicast Forward
Setup
11.1 Static Multicast Forward Setup Overview
This chapter discusses how to configure forwarding rules based on multicast MAC addresses of devices
on your network.
Use these screens to configure static multicast address forwarding.
11.1.1 What You Can Do
Use the Static Multicast Forward Setup screen (Section 11.2 on page 135) to configure rules to forward
specific multicast frames, such as streaming or control frames, to specific port(s).
11.1.2 What You Need To Know
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 105 on page 135 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 106 on
page 135 shows frames being forwarded to devices connected to port 3. Figure 107 on page 135 shows
frames being forwarded to ports 2 and 3 within VLAN group 4.
