Be sure to click on to set your changes; note that the interface’s current

Conﬁguring Fast Ethernet Ports

For any Fast Ethernet interface, the Port Conﬁguration window allows you to

both view and set that port’s available modes. All 100Base-TX Fast Ethernet ports

can be conﬁgured to operate in either standard Ethernet (10 Mbps) or Fast

Ethernet (100 Mbps) mode, and in each mode can be conﬁgured 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 (ﬁber) ports can be conﬁgured 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 interface’s link partner.

To access the Port Conﬁguration Window:

1. From the Module View, click to select the port you wish to conﬁgure; the port

menu will display;

From the Bridge Status window, click to select the port you wish to conﬁgure;

the bridge port menu will display.

2. Drag down to Conﬁguration, and release. The Fast Ethernet Port

Conﬁguration window, Figure 2-9, will appear.
