120 | Configuring Interfacesw w w . d e l l . c o m | s u p p o r t . d e l l . c o m Enabling an InterfacePorts are shut down by default. To enable them, you can do so in bulk mode or per port. For more on bulkconfiguration, see Bulk Configuration on page 126.To enable an individual port, use the following sequence of commands:Configuring Speed and Duplex ModeAs stated above, ports are set by default to auto-negotiate their speed and duplex mode. While you are stillin Interface Config mode, you can use the following commands to manually set the speed and duplexmode. (See also Bulk Configuration on page 126.)The show port unit/slot/port command indicates in the Admin Mode field whether the port isadministratively enabled or shut down, in the Physical Mode field whether auto-negotiation is selected, thespeed and duplex, and, in the Physical Status field, the speed and duplex mode.Step Command Syntax Command Mode Purpose1 interface unit/slot/port Global Config To access the Interface Config mode for the selected port, enterthe keyword interface followed by the port number in unit/slot/port format. For example, to configure port 4 on stack member2, enter interface 2/0/4.2 no shutdown Interface Config Enable the selected interface.Step Command Syntax Command Mode Purpose1 no auto-negotiate Interface Config Disable auto-negotiation on the selected port.2 speed {{10 | 100 |1000} {half-duplex |full-duplex}}Interface Config Manually set the speed and duplex mode on the selected port.For example, you would do this if your port is to be connectedto a port that does not support auto-negotiation.Note: The 10G ports that are in the optional rear moduleof the S50 do not support the speed command or the noauto-negotiate command. You must let themauto-negotiate their connections.3 exit Interface Config Exit to the Global Config mode.4 exit Global Config Exit to the Privileged Exec mode.5 show port unit/slot/portPrivileged Exec Verify that the port is enabled and that the speed is set. SeeFigure 7-86.
