7 Selecting Duplex Mode
(Optional)
Duplexing is a performance option that lets you choose how the
adapter sends and receives data packets over the network. The
adapter can operate at full duplex only when connected to a full
duplex 10BASE-T or 100BASE-TX switch, or to another full
duplex adapter.
The possible settings for duplexing are:
• Auto (requires a full duplex adapter or switch with
auto-negotiation capability). The adapter 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 adapter runs
at half duplex.
• Full duplex (requires a full duplex switch or
adapter). The adapter can send and receive packets
at the same time. This mode can increase adapter
performance capability. If the full duplex switch
provides auto-negotiation, the adapter runs at full
duplex. If the full duplex switch does not provide
auto-negotiation, you need to set the adapter duplex
mode manually (see the following sections), because
it defaults to half duplex.
• Half duplex. The adapter performs one operation at
a time; it either sends or receives.
NOTE If an adapter is running at 100 Mbps and
half-duplex, your potential bandwidth is
higher than if you run it at 10 Mbps and full
duplex.
