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. The frame with a destination MAC address matching the entry is sent out of
multiple ports.
For example, in NLB unicast mode:
All servers within the cluster uses the cluster's MAC address as their own address.
•
Frames destined for the cluster are forwarded to every server.
•
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 through all
ports connected to the servers within the cluster.
Figure 3 NLB cluster
Do not configure an interface as the output interface of a multiport unicast MAC address entry if the
interface receives frames destined for the multiport unicast MAC address. Otherwise, the frames are
flooded on the VLAN to which they belong.
You can configure a multiport unicast MAC address entry globally or on an interface.
