DUPLEX LAN CONFIGURATION

NEC Express5800/ft series uses Bonding for duplex of 1000 BASE LAN cards controlled by the igb
driver and builds them as bond*(*=0,1,2...) device.

Functional overview

For duplicating a LAN, active backup for bonding is used. Active backup is a coupled-interface
using multiple LAN controllers. When only active LAN controller fails, this function allows for
continued operation by immediately switching to a backup controller.

Operable network configuration

For NEC Express5800/ft series, network interface names are based on the naming convention as
described in the table below. Network duplication is achieved by pairing network interfaces of PCI
slots in CPU/IO module 0 and network interfaces in the same PCI slots in CPU/IO module 1.
PCI slot and network interface name
PCI slot
On Board
PCI-e slot 1
PCI-e slot 2
PCI-e slot 3
PCI-e slot 4
*The number enclosed with brackets in the CPU/IO module
column is slot numbers allocated by vndctl described later. The
slot numbers are allocated one-to-one to each interface pair.

Configuring duplication

The following shows information on how to configure duplication by using the settings shown
below as an example.
