Manually Configuring for Full Duplex

If your switch supports auto-negotiation with the N-way standard, duplex configuration is automatic and no action is required on your part. However, few switches in the current installed base support auto-negotiation. Check with your network system administrator to verify. Most installations will require manual configuration to change to full duplex.

Configuration is specific to the driver you’re loading for your network operating system (NOS), as shown in the following paragraphs.

To set up the duplex mode, refer to the section below that corresponds to your operating system.

Adapter performance may suffer or your adapter may not operate if your hub does not support full duplex and you configure the adapter to full duplex. Leave the adapter on half duplex if you are not sure what type of hub you are connected to.
