Network Load Balancing (Nlb) Commands - D-Link xStack DGS-3400 Series Cli Reference Manual

xStack
The NLB indicates the Network Load Balancing: it is a MAC forwarding control for supporting Microsoft's Network Load
Balancing technique.
The Network Load Balancing (NLB) commands in the Command Line Interface (CLI) are listed (along with the
appropriate parameters) in the following table.
Command
create nlb multicast_fdb
delete nlb multicast_fdb
config nlb multicast_fdb
show nlb fdb
Each command is listed, in detail, in the following sections.

Parameters
[<vlan_name 32> | vlanid <vlanid>] <macaddr>
[<vlan_name 32> | vlanid <vlanid>] <macaddr>
[<vlan_name 32> | vlanid <vlanid>] <macaddr> [add | delete] <portlist>
Use to create the switch's NLB multicast FDB entry.
create nlb multicast_fdb [<vlan_name 32> | vlanid <vlanid>] <macaddr>
The create nlb multicast_fdb command creates a NLB multicast FDB entry. The number of
supported entries is project dependent.
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 multicast mode. 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.
The NLB multicast FDB entry will be mutual exclusive with the L2 multicast entry.
vlan_name - Specify the VLAN of the NLB multicast FDB entry to be created.
vlanid <vlanid> - Specify the VLAN by the VLAN ID.
<macaddr> - Specify the MAC address of the NLB multicast FDB entry to be created.
Only Administrator and Operator-level users can issue this command.
Use to delete the switch's NLB multicast FDB entry.
delete nlb multicast_fdb [<vlan_name 32> | vlanid <vlanid>] <macaddr>
The delete nlb multicast_fdb command is used to delete the NLB multicast FDB entry.
