3-13 Common Multicast ConfigurationCommon Multicast ConfigurationConfiguring a Multicast MAC Address EntryIn Layer 2 multicast, the system can add multicast forwarding entries dynamically through a Layer 2multicast protocol. Alternatively, you can statically bind a port to a multicast MAC address entry byconfiguring a multicast MAC address entry manually.Generally, when receiving a multicast packet for a multicast group not yet registered on the switch, theswitch will flood the packet within the VLAN to which the port belongs. You can configure a staticmulticast MAC address entry to avoid this.Table 3-1 Configure a multicast MAC address entry in system viewOperation Command RemarksEnter system view system-view —Create a multicast MACaddress entrymac-address multicastmac-address interfaceinterface-list vlan vlan-idRequiredThe mac-address argumentmust be a multicast MACaddress.Table 3-2 Configure a multicast MAC address entry in Ethernet port viewOperation Command RemarksEnter system view system-view —Enter Ethernet port view interface interface-typeinterface-number —Create a multicast MACaddress entry.mac-address multicastmac-address vlan vlan-idRequiredThe mac-address argumentmust be a multicast MACaddress.
