NLB FDB Settings
This window is used to display and configure the Network Load Balancing (NLB) FDB settings.
The Network Load Balancing (NLB) function 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
the servers, but will only be processed by one of them. The server can work in two different modes:
• Unicast mode: The client uses a unicast MAC address as the destination MAC address to reach the server.
• Multicast mode: The client uses a multicast MAC address as the destination MAC address to reach the server.
This destination MAC address is called the shared MAC address. However, the server uses its own MAC address
(rather than the shared MAC address) as the source MAC address in the reply packet. In other words, a NLB unicast
address usually is not the source MAC address of a packet.
When the received packet contains the destination MAC address matches the configured unicast MAC address, it will
be forwarded to those configured ports, regardless of the VLAN membership configuration.
Administrators cannot configure a static address of the MAC address table as a NLB address. However, if a MAC
address is created as a NLB MAC address entry, the same MAC address can be still dynamically learnt in the Layer 2
MAC address table. In this situation, the NLB has higher priority; the dynamically learnt FDB entry won't take effect.
To view the following window, click Management > NLB FDB Settings, as shown below:
