How to add multicast MAC addresses to a static Port

Multicast MAC addressIs a type of logical MAC address. This MAC address represents a multicast group. All members in this group receive data frames with the target address of the multicast MAC address corresponding to this group. To better understand the concept of multicast and MAC address, let's look at the following Configuration:

Case requirements

1. in the process of layer-2 multicast, in addition to dynamically creating a multicast Forwarding Table item through the layer-2 multicast protocol, you can also manually configure the multicast MAC Address Table item, statically bind the port to the multicast address table. Generally, if the multicast address in the multicast data packet received by the switch is not registered on the local computer, the message is broadcasted in the VLAN where the port is located, this situation can be avoided by configuring the multicast static MAC Address Table item;

2. This case applies to the following products at the same time:

H3C 3100-SI, 5100, 3500, 3600, 5600, 3610, 5500-SI, 5510 series switches.

3. The networking diagram of this case is as follows:

Procedure

1. Go to the System View

<H3C> system-view

2. Add the multicast MAC Address Table item statically and add the Ethernet1/0/1 ports in vlan 2 to the multicast group corresponding to the multicast MAC 0180-C2FF-FFFF.

[H3C] mac-address multicast 0180-C2FF-FFFF interface Ethernet1/0/1 vlan 2

The process of adding multicast MAC addresses is over. Although it is not very complicated, it is also an indispensable step.
