Chapter 3 Multicast MAC Address Entry
3.1 Introduction
In Layer 2 multicast, the system can add multicast forwarding entries dynamically
through Layer 2 multicast protocol. However, you can also statically bind a port to a
multicast address entry by configuring a multicast MAC address manually.
Generally, when receiving a multicast packet whose multicast address has not yet been
registered on the switch, the switch broadcasts the packet in the VLAN. However, you
can configure a static multicast MAC address entry to avoid this case.
