IntroductionThe Command Language Interface (CLI) is a network management application operatedthrough an ASCII terminal without the use of a Graphical User Interface (GUI) driven software

application. By directly entering commands, you achieve greater configuration flexibility. TheCLI is a basic command-line interpreter similar to the UNIX C shell.

You can configure and maintain a device by entering commands from the CLI, which is basedsolely on textual input and output; you enter commands using a terminal keyboard and thetextual output displays via a terminal monitor. You can access the CLI from a VT100 terminalconnected to the console port of the device or through a Telnet connection from a remote host.

The first time you use the CLI from the console a Setup Wizard is invoked. The Setup Wizard

guides you in setting up a minimum configuration, so that the device can be managed from theWeb Based Interface. Refer to the Getting Started Guide and User Guide for more informationon the Setup Wizard.

This guide describes how the Command Line Interface (CLI) is structured, describes thecommand syntax, and describes the command functionality.

This guide also provides information for configuring the PowerConnect device, details theprocedures, and provides configuration examples. Basic installation configuration is described in

the Users Guide and must be completed before using this document.

Command GroupsThe system commands can be broken down into functional groups as shown below.

AAA Configures connection security including authorization and

passwords.ACL Configures and displays ACL information.
