DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide Click the Delete button to remove the specified reboot schedule. 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 is usually not the source MAC address of a packet. When the received packet contains a destination MAC address that 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: Figure 4-106 NLB FDB Settings Window The fields that can be configured are described below: Parameter NLB Type VID MAC Address Unit From Port - To Port Description Select the NLB type here. Options to choose from are Unicast and Multicast. After selecting Multicast as the NLB type, enter the VLAN ID used in this configuration here. Enter the unicast or multicast MAC address of the entry here. If a received packet contains a destination MAC address that matches the specified MAC address, it will be forwarded to the specified interface. Select the Switch unit ID that will be used here.

multiple servers can share the same IP address and MAC address. The requests from clients will be forwarded to all

Unicast mode:

The client uses a unicast MAC address as the destination MAC address to reach the server.

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
