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
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.
static multicast forwarding, you can forward these multicasts to port(s) within a VLAN group.
