Use the options in this window to select the desired mode:

Standard Mode

In Standard Mode, an interface can only either transmit or receive at any given
time, and must wait for one activity to be completed before switching to the next
activity (receive or transmit). In this mode, standard wire speeds (10 Mbps for
Ethernet, 100 Mbps for FDDI) are available.

Full Duplex

In Full Duplex Mode, an interface can both receive and transmit packets at the
same time, effectively doubling the available wire speed to 20 Mbps (for Ethernet)
or 200 Mbps (for FDDI).

Be sure to click on

to set your changes; note that the interfaceÕs current

mode can be determined by the Þeld selected in the window.

Configuring Fast Ethernet Ports

If you have any Fast Ethernet NIMs installed in your SmartSwitch 7000 chassis,
the Port ConÞguration window available for those ports allows you to both view
and set that portÕs available modes. All 100Base-TX Fast Ethernet ports can be
conÞgured to operate in either standard Ethernet (10 Mbps) or Fast Ethernet (100
Mbps) mode, and in each mode can be conÞgured to operate in Full Duplex,
effectively doubling the available wire speed (from 10 to 20 Mbps in standard
Ethernet mode, or from 100 to 200 Mbps in Fast Ethernet mode); 100Base-FX
(Þber) ports can be conÞgured to operate in their standard 100 Mbps mode, or in
full duplex mode. This window also displays the mode currently in effect on the
selected interface, and provides some information (where it is available) about the
interfaceÕs link partner.

TIP

Note that, if you select the ConÞguration option available for a Fast Ethernet interface, an
entirely different window will appear; see ConÞguring Fast Ethernet Ports, below, for
information on conÞguring these ports.
