    Navigating the CLI

    You can use the commands described in this topic to navigate the CLI. For a complete description of the CLI, see Unresolved xref.

    To navigate the CLI:

    • Move from User Exec to Privileged Exec mode. Privileged Exec mode allows you to access all other user interface modes. From here you can configure, monitor, and manage all aspects of the router. You can access the Privileged Exec commands using one of 16 levels of command privilege. If you do not enter a privilege level and you are not accessing the router through a RADIUS authentication account, the default CLI access level is 10. For information about CLI levels of access, see Unresolved xref in Unresolved xref.
      host1>enable 15host1#

      Set a password for this mode by using either the enable password or the enable secret command in Global Configuration mode. This protects the system from any unauthorized use. Once a password is set, anyone trying to use Privileged Exec mode will be asked to provide the password.

      host1>enablepassword:*******host1#
    • Enter Global Configuration mode. This mode provides access to other configuration modes, such as Interface Configuration mode. See Unresolved xref.
      • To allow other commands to be executed from a terminal:
        host1#configureConfiguring from terminal or file [terminal]?Enter configuration commands, one per line. End with CNTL/Z.host1(config)#
      • To allow other commands to be executed from a file:
        host1#configureConfiguring from terminal or file [terminal]? fileFile name: system1.scrProceed with configure? [confirm] host1(config)#

      Note: This command is not allowed for a short time after a warm restart (warm switchover) occurs. This delay allows some applications time to complete their warm-restart initialization. However, if the warm restart is not complete in 5 minutes, the warm start is cancelled and configuration access is restored.

    • Issue an Exec mode command from any CLI configuration command mode. The run command functions the same as the do command.
      host1(config)#run show configuration | begin interface
    • Issue an Exec mode command from any CLI configuration command mode. The do command functions the same as the run command.
      host1(config)#do show configuration | begin interface
    • Exit Global Configuration mode or any of the other Configuration modes and return to the User Exec mode. You may also use Ctrl+z to exit these modes.
      host1(config)#end host1#
    • Display basic information about the interactive help system.
      host1#helpUse the help options as follows:
      ?, or command<Space>? - Lists the set of all valid next keywords or argumentspartial-keyword? - Lists the keywords that begin with a certain character stringpartial-keyword<Tab> - Completes the partial keyword
    • Make the CLI pause for a specified period of time (in seconds). Pausing is very useful in configuration script files.
      host1#sleep 60
    • Move to a lower Privileged Exec mode level without returning to User Exec mode. Specifying a privilege level after the disable command changes the Privileged Exec mode to the lower level that you specify; you do not return to User Exec mode.
      host1#show privilege Privilege level is 10host1#disable 5 host1#show privilege Privilege level is 5
    • Exit Privileged Exec mode and return to User Exec mode.
      host1#disablehost1>
    • Exit the current command mode or the system when issued from the User Exec mode.
      host1#exithost1>
