Command GroupsIntroduction

1

The Command Line 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, the user has greater configuration flexibility. The CLI is a basic command-line interpreter similar to the UNIX C shell. A switch can be configured and maintained by entering commands from the CLI, which is based solely on textual input and output with commands being entered by a terminal keyboard and the output displayed as text via a terminal monitor. The CLI can be accessed from a console terminal connected to an EIA/TIA-232 port or through a Telnet session. This guide describes how the CLI is structured, describes the command syntax, and describes the command functionality. This guide also provides information for configuring the PowerConnect switch, details the procedures, 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 three sets of functional groups, Layers 2, Layer 3, and Utility.Table 1-1. System Command Groups Description Configures connection security including authorization and passwords. Configures and displays ACL information.
