Operation Manual – MulticastH3C S5100-SI/EI Series Ethernet Switches Chapter 3 Common Multicast Configuration3-1Chapter 3 Common Multicast Configuration3.1 Common Multicast Configuration3.1.1 Configuring a Multicast MAC Address EntryIn Layer 2 multicast, the system can add multicast forwarding entries dynamicallythrough a Layer 2 multicast protocol. Alternatively, you can statically bind a port to amulticast MAC address entry by configuring a multicast MAC address entry manually.Generally, when receiving a multicast packet for a multicast group not yet registered onthe switch, the switch will flood the packet within the VLAN to which the port belongs.You can configure a static multicast 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-addressargument must be amulticast MAC address.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-addressargument must be amulticast MAC address.
