Chapter 5 Multicast MAC Address Entry
Configuration
5.1 Overview
In Layer 2 multicast, the system can create 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 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. However, you can configure a static multicast MAC address entry to avoid
this case.
5.2 Configuring a Multicast MAC Address Entry
You can configure multicast MAC address entries in system view.
Follow these steps to configure a multicast MAC address entry in system view:
