Select Duplex Mode (Optional)
Duplexing is a performance option that lets you choose how the NIC sends and
receives data packets over the network. The NC3131 Fast Ethernet NIC can
operate at full duplex only when connected to a full duplex 10Base-T/100Base-
TX switch, or another full duplex NIC.
Full duplex (requires a full duplex switch and NIC). The NIC can
send and receive packets at the same time. This mode can increase NIC
performance. If the full duplex switch does not provide auto-
negotiation, you must manually set the NIC and the switch to full
duplex.

Writer: Weldon W. Rowan Project: NIC Installation Comments:
File Name:TOR_2.DOC Last Saved On:7/24/98 2:51 PM
Auto (requires a full duplex NIC and switch with auto-negotiation
capability). The NIC negotiates with the switch to send and receive
packets at the highest rate. This is the default setting. If the switch does
not provide auto-negotiation, the NIC runs at half duplex.
Half duplex. The NIC performs one operation at a time; it either sends
or receives.
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,
there are a few switches in the current installed base that do not support auto-
negotiation. Check with your network system administrator to verify. These
installations will require manual configuration to change to full duplex.
Configuration is specific to the driver you are loading for your network
operating system (NOS).
To set up the duplex mode, refer to the section below that corresponds to your
operating system. In some installations, you may need to force “speed” and
“duplex” to establish connections properly with some network topologies.
CAUTION: NIC performance may suffer or your NIC may not operate if
your switch does not support full duplex and you configure the NIC to full
duplex.
NetWare Server
In AUTOEXEC.NCF, load N100.LAN and add the following statement (you
must include the equal sign):
FORCEDUPLEX=2
SPEED=100 (or 10 if 10Base-T)
For more information, see the README file for NetWare servers.
