Introduction

This guide is intended for use with the following switches:

■HP ProCurve 2520-8-PoE Switch

■HP ProCurve 2520-24-PoE Switch

It describes how to use the command line interface (CLI), Menu interface, and web browser to configure, manage, monitor, and troubleshoot switch opera tion. For an overview of other product documentation for the above switches, refer to “Product Documentation” on page xi. You can download documenta tion from the ProCurve Networking web site, www.procurve.com.

Conventions

Configuration and Operation Examples

Unless otherwise noted, examples using a particular switch model apply to all switch models covered by this guide.

Protocol Acronyms

IP Refers to the IPv4 protocol unless otherwise noted.

IPv6 Refers to the IPv6 protocol.

Command Syntax and Displayed Information

Command Syntax Statements

Syntax: ip < default-gateway < ip-addr >> | routing >

Syntax: show interfaces [port-list ]

■Vertical bars ( | ) separate alternative, mutually exclusive elements.

■Square brackets ( [ ] ) indicate optional elements.

■Braces ( < > ) enclose required elements.

1-2

Getting Started

Conventions

■Braces within square brackets ( [ < > ] ) indicate a required element within an optional choice.

■Boldface indicates use of a CLI command, part of a CLI command syntax, or other displayed element in general text. For example:

“Use the copy tftp command to download the key from a TFTP server.”

■Italics indicate variables for which you must supply a value when execut ing the command. For example, in this command syntax, you must provide one or more port numbers:

Syntax: aaa port-access authenticator < port-list >

Command Prompts

In the default configuration, your switch displays a CLI prompt similar to the following example:

ProCurve 2520-8-PoE#

To simplify recognition, this guide uses ProCurve to represent command prompts for all switch models. For example:

ProCurve#

(You can use the hostname command to change the text in the CLI prompt.)

Screen Simulations

Displayed Text. Figures containing simulated screen text and command output look like this:
