CHAPTER 11

Static Multicast Forward Setup

11.1 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 104) 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. You can configure this in the Advanced Application > Multicast > Multicast

Setting screen (see Section 23.3 on page 171). Figure 63 shows such unknown multicast frames

flooded to all ports. With static multicast forwarding, you can forward these multicasts to port(s)
