Indigo - Open Source OpenFlow Switches
Table of Contents
Overview
This is a place to accumulate information about the Indigo CLI. It needs to be worked in to a full reference manual
The help command in the CLI provides the most up to date information for the version of software running on the switch.
Running the CLI
The CLI is normally invoked interactively with the command cli. A single CLI command may be run with the cmd command. This is useful as you can use shell pipes. For example:
cmd flowtable | grep 192.168.1.150
A file of CLI commands can be executed with cmd -f <filename>.
Command Line Options
The command line options below require the CLI be invoked from the switch_cli directory.
The commands -e, -f and -b are non-interactive commands.

Command Line Editing
In general, commands can be edited while being entered with arrow or special command keys. Command completion is done with the 'tab' key. Currently command completion The following keys provide editing functions.
Command history is supported up to 100 lines. Empty lines and repeated lines are not stored in history.

Command Parameters
There are two types of command line parameters:
- Positional parameters
- Keyword parameters
Positional parameters determine their meaning from their position (first parameter means...) Keyword parameters are usually of the form "keyword=value". Some keyword parameters may not take a value and thus are considered "flags". They typically start with a hyphen, -.
Positional parameters must precede keyword parameters. Positional parameters are ended by:
- The parsing description specifies no more positional parameters
- A = occurs after the next token
- The next token starts with - (indicating a "flag" keyword parameter)
- End of the line
Examples
SwitchCLI# port set 3 speed=1000 mtu-1600
- 'set' is a positional parameter, the subcommand.
- '3' is a positional parameter, the port specification
- 'speed' and 'mtu' are keyword parameters
SwitchCLI# port show 1-10 -l
- 'show' is a positional parameter, the subcommand.
- '1-10' is a positional parameter, the port specification
- '-l' is a keyword flag parameter
SwitchCLI# ps -l
- '-l' is a keyword flag parameter; the first positional parameter (port spec) is undefined and, in this case, is given a default value of '*'.
Command Details
cli_stat
Show debug info on CLI
No parameters
config
Show or set configuration parameters
The config command is the primary mechanism for updating the values that determine the initialization sequence of the system. There are a set of known configuration keywords that are documented in the Indigo Initialization and Configuration document. Additional keywords may be added which can be referenced in user generated scripts which source either /etc/find-env or the appropriate sysenv file.
Syntax
config <sub-command> [<variable> [<value>] ]
Examples:
command |

Set dp_mgmt to yes in saved config |
config delete dp_mgmt |
Delete dp_mgmt from saved config |

Limitations
- Command completion is only supported at the end of a line. Hitting 'tab' when the cursor is in the middle of a line will move the cursor to the end of the line and perform completion on that token.
