Command Groups

Introduction

The Command Language Interface (CLI) is a network management application operated through an ASCII terminal without the use of a Graphic User Interface (GUI) driven software application. By directly entering commands, you have greater configuration flexibility. The CLI is a basic command-line interpreter similar to the UNIX C shell.

An Ethernet Switch Module can be configured and maintained by entering commands from the CLI, which is based solely on textual input and output with commands being entered from a terminal keyboard and the output displayed as text via a terminal monitor. The CLI can be accessed from a VT100 terminal connected to the console port of the Ethernet Switch Module or through a Telnet connection from a remote host.

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

This guide also provides information for configuring the PowerConnect Ethernet Switch Module, details the procedures and provides configuration examples. Basic installation configuration is described in the

Command Groups

User’s Guide

and must be completed before using this document.

The system commands can be broken down into the functional groups shown below.
