Step 8: Set Duplex LAN Configuration

The NEC Express5800/ft series builds a duplex LAN configuration by using "Stratus emb-82576
2-Port Gigabit Adapter" mounted as standard on the CPU/IO module and the extended PCI slot
"Stratus 82576 2-Port Copper Gigabit Adapter.".

Overview

The duplex LAN configuration types are described below:
Adapter Fault Tolerance (AFT)
Adapter Fault Tolerance (AFT) is a feature that places more than one LAN controller on the
same LAN (same segment), and automatically switches the process of the primary controller to
the backup controller when any trouble occurred on the primary.
Adaptive Load Balancing (ALB)
Adaptive Load Balancing (ALB) is a feature that connects more than one LAN controller to
the same hub and enhances the throughput by operating packet transmission from the server.
Receive Load Balancing (RLB) is enabled by default. Disable RLB. When RLB is enabled,
the network duplex configuration may fail.
