Chapter 4 Multicast MAC Address Entry
Configuration
4.1 Overview
In Layer 2 multicast, the system can add multicast forwarding entries dynamically
through a Layer 2 multicast protocol. Alternatively, you can statically bind a port to a
multicast address entry by configuring a multicast MAC address entry manually.
Generally, when receiving a multicast packet whose multicast address has not yet been
registered on the switch, the switch will broadcast the packet in the VLAN to which the
port belongs. You can configure a static multicast MAC address entry to avoid this.
4.2 Configuring a Multicast MAC Address Entry
You can configure multicast MAC address entries in system view or Ethernet port view.
