Duplex Modes 2-73

Bridging
Figure 2-23. Port ConÞguration Window
This window will indicate which mode is being used on the interface, standard
mode or full duplex mode.
Standard Mode
Standard mode is being used on this interface. In standard mode, the interface can
transmit or receive packets. The interface has to wait for one activity to be
completed before switching to the next activity (receive or transmit).
Full Duplex
Full duplex mode is being used on this interface. In full duplex mode, the
interface receives and transmits packets at the same time.
You set an interface to use standard or full duplex by selecting the appropriate
mode from this window. When you open the Port ConÞguration window the
currently used mode appears selected.
To change the mode from standard to full duplex mode or from full duplex to
standard mode, click in the option button of the appropriate option and then click
on Apply. To cancel the action without applying any changes, click on Cancel.
Fast Ethernet Port Configuration
You can use the port-level Fast Ethernet ConÞguration window to manually
conÞgure 100Base-TX Fast Ethernet ports and FE100-TX Fast Ethernet Interface
Modules (FEPIMs) for 10Base-T and 100Base-TX full or half duplex operation.
You can also conÞgure them to auto-negotiate with the device at the other end of
the connection, based upon each deviceÕs Advertised and Remote Capabilities.
If you are monitoring a device with 100Base-FX Fast Ethernet ports, you can use
the Fast Ethernet ConÞguration window to manually conÞgure them to full or
half duplex operation. No auto-negotiation is available for the 100Base-FX ports,
and by extension, no Advertised or Remote capabilities.
