Command Line Interface The command "show interfaces ?" will display the following information: Console# show interfaces ? counters Information of interfaces counters protocol-vlan Protocol-vlan information status s Information of interfaces status switchport Information of interfaces switchport Console# Partial Keyword Lookup If you terminate a partial keyword with a question mark, alternatives that match the initial letters are provided. (Remember not to leave a space between the command and question mark.) For example "s?" shows all the keywords starting with "s." Console# show s? snmp sntp system Console# spanning-tree ssh startup-config Negating the Effect of Commands For many configuration commands you can enter the prefix keyword "no" to cancel the effect of a command or reset the configuration to the default value. For example, the logging command will log system messages to a host server. To disable logging, specify the no logging command. This guide describes the negation effect for all applicable commands. Using Command History The CLI maintains a history of commands that have been entered. You can scroll back through the history of commands by pressing the up arrow key. Any command displayed in the history list can be executed again, or first modified and then executed. Using the show history command displays a longer list of recently executed commands. Understanding Command Modes The command set is divided into Exec and Configuration classes. Exec commands generally display information on system status or clear statistical counters. Configuration commands, on the other hand, modify interface parameters or enable certain switching functions. These classes are further divided into different modes. Available commands depend on the selected mode. You can always enter a question mark "?" at the prompt to display a list of the commands available for the current mode. Exec Commands When you open a new console session on the switch with the user name and password "guest," the system enters the Normal Exec command mode (or guest mode), displaying the "Console>" command prompt. Only a limited number of the commands are available in this mode. You can access all commands only from the Privileged Exec command mode (or administrator mode). 1-4 www.hp.com CLI Reference Guide
