8. Command Line Interface

The Command Line Interface (CLI) offers a unified control interface to the router and can be used to get/set configuration parameters, apply updates, restart services or perform other system tasks.

The CLI should be started using cli -i command from system shell or when logging as root user. A list of available commands can be displayed by running cli -l. It will be started automatically in interactive mode when logging in as admin user.

$ cli
Name:
        cli (Command Line Utility)

Usage:
         [-ilvh] <command>
~ $ cli -i

Enter 'help' for a list of available commands
or hit the TAB key for auto-completion.

Ready to serve. 

>

The CLI supports the TAB completion, that is expanding entered words or fragments by hitting the TAB key at any time. This applies to commands but also to arguments and generally offers a convenient way for working on the shell.

Please note that each CLI session will perform an automatic logout as soon as a certain time of inactivity (10 minutes by default) have been reached. It can be turned off by the command no-autologout.

The CLI can be exited by running exit.

8.1. General usage

When operating the CLI in interactive mode, each entered command will be executed by the RETURN key. You can use the Left and Right keys to move the current point between entered characters or use the Up and Down keys to search the history of entered commands. Pressing CTRL-c twice or CTRL-d on an empty command line will exit the CLI.

List of supported key sequences:

Key SequenceAction
CTRL-aMove to the start of the current line.
CTRL-eMove to the end of the line.
CTRL-fMove forward a character.
CTRL-bMove back a character.
ALT-fMove forward to the end of the next word.
ALT-bMove back to the start of the current or previous word.
CTRL-lClear the screen leaving the current line at the top of the screen, with an argument given refresh the current line without clearing the screen.
CTRL-pFetch the previous command from the history list, moving back in the list.
CTRL-nFetch the next command from the history list, moving forward in the list.
ALT-<Move to the first line in the history.
ALT->Move to the end of the input history.
CTRL-rSearch backward starting at the current line and moving up through the history.
CTRL-sSession will be frozen.
CTRL-qReactivate frozen session.
CTRL-dDelete character at point or exit CLI if at the beginning of the line.
CTRL-tDrag the character before point forward moving point forward as well. If point is at the end of the line, then this transposes the two characters before point.
ALT-tDrag the word before point past the word after point, moving point over that word as well. If point is at the end of the line, this transposes the last two words on the line.
CTRL-kDelete the text from point to the end of the line.
CTRL-yYank the top of the deleted text into the buffer at point.

Please note, that it can be required to apply quotes (“) when entering commands with arguments containing whitespaces.

The following sections are trying to explain the available commands.

8.2. Print help

8.16. CLI–PHP

CLI-PHP, an HTTP front-end to the CLI application, can be used to configure and control the router remotely. It is enabled in factory configuration, thus can be used for deployment purposes, but disabled as soon as the admin account has been set up. The service can later be turned on/off by setting the cliphp.status configuration parameter:

> get cliphp.status
cliphp.status=0

> set cliphp.status=1
> get cliphp.status
cliphp.status=1
          cliphp.status=0           Service is disabled
          cliphp.status=1           Service is enabled

This section describes the CLI-PHP interface for Version 2, the general usage (GET requests) is defined as follows:

Usage:
    http (s)://cli.php?<key1>=<value1>&<key2>=<value2>..<keyN>=<
    valueN>
Available keys:
output             Output format ( html, plain )
usr                Username to be used for authentication
pwd                Password to be used for authentication
commandV           Command to be executed
arg0..arg31        Arguments passed to commands
Notes:
    The commands correspond to CLI commands as seen by 'cli −l', the arguments
   (arg0..arg31) will be directly passed to the cli application 

    Thus, an URL containing the following sequence:

      command=get&arg0=admin.password&arg1=admin.debug&arg2=admin.access

   will lead to cli being called as:

    $ cli get "admin.password" "admin.debug" "admin.access"

    It supports whitespaces but please be aware that any special characters in the URL
    must be specified according to RFC1738 (which usually done by common clients such
    as wget, lynx, curl).

Response:
    The returned response will always contain a status line in the format:

    <return>: <msg>

    with return values of OK if succeeded and ERROR if failed. Any output from the
    commands will be appended

Examples:

    OK: status command successful
    ERROR: authentication failed
