Documentation
This guide is for network administrators who are responsible for operating and
maintaining network equipment. The guide assumes a basic working knowledge of
LANs (Local Area Networks), the Internet Protocol (IP), and Simple Network
Management Protocol (SNMP).
This guide describes the switch’s command line interface (CLI). For more detailed
information on the switch’s key features or information about the web browser
management interface refer to the Web Management Guide.
The guide includes these sections:
◆
Section I “Getting Started” — Includes information on initial configuration.
◆
Section II “Command Line Interface” — Includes all management options
available through the CLI.
◆
Section III “App en di ce s” — Includes information on troubleshooting switch
management access.
This guide focuses on switch software configuration through the CLI.
For information on how to manage the switch through the Web management
interface, see the following guide:
