Adding or modifying a multiport unicast MAC address entry
About multiport unicast MAC address entry configuration
You can configure a multiport unicast MAC address entry to associate a unicast destination MAC
address with multiple ports. The frame with a destination MAC address matching the entry is sent out
of multiple ports.
For example, in NLB unicast mode (see Figure 1):
• All servers within a cluster uses the cluster's MAC address as their own address.
• Frames destined for the cluster are forwarded to every server in the group.
In this case, you can configure a multiport unicast MAC address entry on the device connected to the
server group. Then, the device forwards the frame destined for the server group to every server
through all ports connected to the servers within the cluster.
