47-1 create nlb unicast_fdb
Description
This command is used to create the NLB unicast FDB entry.
The network load balancing command set is used to support 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.
The server can work in two different modes – unicast mode and multicast mode. In unicast mode,
the client use unicast MAC address as the destination MAC to reach the server. In multicast mode,
the client use the multicast MAC address as the destination MAC to reach the server. Regarding of
the mode, this destination Mac is the named the shared MAC. The server uses its own MAC
address (rather than the shared MAC) as the source MAC address of the reply packet.
Format
create nlb unicast_fdb <macaddr>
Parameters
