Introduction
Introduction
This guide is intended for use with the HP ProCurve 6120G/XG and 6120GX switches.
It describes how to use the command line interface (CLI), Menu interface, and web browser to configure, manage, monitor, and troubleshoot switch operation. For an overview of product documentation for the above switches, refer to “Product Documentation” on page xiii. You can download documentation from the following web sites:
www.procurve.com/manuals
www.hp.com/go/bladesystem/documentation
h18004.www1.hp.com/products/blades/components/c-class-tech-installing.html
Conventions
This guide uses the following conventions for commands and screen displays.
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.
■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 executing the command. For example, in this command syntax, you must provide one or more port numbers:
Syntax: aaa port-access authenticator < port-list >

Conventions
Command Prompts
In the default configuration, your switch displays a CLI prompt similar to the following examples:
ProCurve 6120G/XG Blade Switch#
ProCurve 6120XG Blade Switch#
To simplify recognition, this guide uses ProCurve to represent command prompts. 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:
ProCurve> show version
Image stamp: /sw/code/build/vern Feb 20 2009 14:56:49 Z.14.XX
427
Boot Image: Primary
Build Options: QA
Watchdog: ENABLED
Figure 1-1. Example of a Figure Showing a Simulated Screen
In some cases, brief command-output sequences appear without figure identification. For example:
ProCurve(config)# clear public-key ProCurve(config)# show ip client-public-key show_client_public_key: cannot stat keyfile
Configuration and Operation Examples
Keys
Simulations of actual keys use a bold, sans-serif typeface with square brackets. For example, the Tab key appears as [Tab] and the “Y” key appears as [Y].
