NLB FDB Settings

The Switch supports Network Load Balancing (NLB). This is a MAC forwarding control for supporting the Microsoft

server load balancing application where multiple servers can share the same IP address and MAC address. The

requests from clients will be forwarded to all servers, but will only be processed by one of them. In multicast mode,

the client uses a multicast MAC address as the destination MAC to reach the server. Regardless of the mode, the

destination MAC is the shared MAC. The server uses its own MAC address (rather than the shared MAC) as the

source MAC address of the reply packet. The NLB multicast FDB entry will be mutually exclusive with the L2

multicast entry.

To view the following window, click L2 Features > NLB FDB Settings, as shown below.
