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 118) 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
23.3on page 195). Figure 61 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 62 shows frames being forwarded to devices
