The SmartSwitch 7000 Chassis View2-24Managing the HubFigure 2-12. Port ConfigurationUse the options in this window to select the desired mode:Standard ModeIn Standard Mode, an interface can only either transmit or receive at any giventime, and must wait for one activity to be completed before switching to the nextactivity (receive or transmit). In this mode, standard wire speeds (10 Mbps forEthernet, 100 Mbps for FDDI) are available.Full DuplexIn Full Duplex Mode, an interface can both receive and transmit packets at thesame 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 interface’s currentmode can be determined by the field selected in the window.Configuring Fast Ethernet PortsIf you have any Fast Ethernet NIMs installed in your SmartSwitch 7000 chassis,the Port Configuration window available for those ports allows you to both viewand set that port’s available modes. All 100Base-TX Fast Ethernet ports can beconfigured to operate in either standard Ethernet (10 Mbps) or Fast Ethernet (100Mbps) 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 standardEthernet 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 infull duplex mode. This window also displays the mode currently in effect on theselected interface, and provides some information (where it is available) about theinterface’s link partner.TIPNote that, if you select the Configuration option available for a Fast Ethernet interface, anentirely different window will appear; see Configuring Fast Ethernet Ports, below, forinformation on configuring these ports.
