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.
