VLAN.
Adding or modifying a multiport unicast MAC address entry
You can configure a multiport unicast MAC address entry to associate a unicast destination MAC
address with multiple ports, so that the frame with a destination MAC address matching the entry is
forwarded out of multiple ports. For example, when a group of servers are processing a request from a
client, the client is not concerned with the details of these servers and believes that only one server is
responding. In this case, you can configure a multiport unicast MAC address entry on the device
connected to the group of servers. In this manner, the device forwards the frame destined for the server
group (the one server from the perspective of the client) to every server.
To configure a multiport unicast MAC address entry globally:
Step Command Remarks
1. Enter system view. system-view N/A
2. Add or modify a multiport
unicast MAC address entry.

Make sure you have created the
VLAN and assigned the interface
