47Local Management: Overview, Setup, and NavigationEthernet Port Specific Configuration FieldsThe following explains each Ethernet Port Specific Configuration Screen field.Interface (Read-Only)Displays the Interface number.Physical Port (Read-Only)Displays the number of the physical port on the interface.Default Speed (Read-Only)Displays the current operational speed in Mbps. The 9H532-24 can operate at 10Mbps or 100 Mbps. The 9H531-24 and 9H539-24 modules operate at 100 Mbps.Default Duplex (Toggle)The choices are Half, for half duplex, or Full, for full duplex. If Auto-Negotiationis disabled for the port, then the port defaults to operate in the setting displayed.To choose the Default Duplex, see “Selecting and Changing Settings” on page 49.Auto-Negotiation State (Toggle)Determines whether Auto-Negotiation is Enabled or Disabled for the specificport. During auto-negotiation, the port “tells” the device at the other end of thesegment what its capabilities are. If Auto-Negotiation is disabled, the port revertsto the speed, duplex and flow control settings specified by Default Speed, DefaultDuplex, Half Duplex Flow Control and Full Duplex Flow Control fieldsrespectively.Advertised Ability (Selectable)In normal operation, with all capabilities enabled, the port “advertises” that it hasthe ability to operate in any mode. A user may choose to set up the port so thatonly a portion of the available capabilities are advertised and the others aredisabled. The left field displays the advertised ability of the port, but onlybecomes active on ports that have Auto-Negotiation enabled. The status of aparticular ability is displayed in the right field. The “T” in an ability stands fortwisted pair. Possible abilities are listed below. Not all choices listed below will beavailable, as the module will display only the choices available to it.• 10Base-T – 10 Mbps operation• 10Base-TFD – 10 Mbps full duplex operation• 100Base-TX – 100 Mbps operationAuto-Negotiation is not supported on the 9H531-24 and 9H539-24 modules.NOTE
