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.
