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 opera-
tion. 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 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 >

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:
Figure 1-1. Example of a Figure Showing a Simulated Screen
In some cases, brief command-output sequences appear without figure iden-
tification. 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].
