Introduction
Introduction
This Access Security Guide is intended for use with the following switches:
■ HP Procurve Switch 4104GL
■ HP Procurve Switch 4108GL
Together, these two devices are termed the Series 4100GL switches.
This guide describes how to use the command line interface (CLI), Menu
interface, and web browser interface to configure, manage, and monitor
switch operation. A troubleshooting chapter is also included.
For information on other product documentation for Series 4100 switches,
refer to “Related Publications” on page xx.
The Product Documentation CD-ROM shipped with the switch includes a
copy of this guide. You can also download a copy from the HP Procurve
website. (See “Getting Documentation From the Web” on page xxi, below.)
Conventions
This guide uses the following conventions for command syntax and displayed
information.
Command Syntax Statements
Syntax: aaa port-access authenticator < port-list >
[ control < authorized | auto | unauthorized >]
■ 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:
xviii
Syntax: aaa port-access authenticator < port-list >

Simulating Display Output
Simulating Display Output
Commands or command output positioned to simulate displays of switch
information in a computer screen are printed in a monospace font.
Command Prompts
In the default configuration, your Series 4100GL switch displays one of the
following CLI prompts:
HP Procurve Switch 4104#
HP Procurve Switch 4108#
To simplify recognition, this guide uses HPswitch to represent command
prompts for all models. For example:
HPswitch#
(You can use the hostname command to change the text in the CLI prompt.)
Screen Simulations
Figures containing simulated screen text and command output look like this:
Figure 1. Example of a Figure Showing a Simulated Screen
In some cases, brief command-output sequences appear without figure identification. For example:
HPswitch(config)# clear public-key
HPswitch(config)# show ip client-public-key
show_client_public_key: cannot stat keyfile

IP Addressing. If you just want to give the switch an IP address so that it
can communicate on your network, or if you are not using VLANs, HP
recommends that you use the Switch Setup screen to quickly configure IP
addressing. To do so, do one of the following:
■ Enter setup at the CLI Manager level prompt.
HPswitch# setup
■ In the Main Menu of the Menu interface, select
8. Run Setup
For more on using the Switch Setup screen, see the Installation and Getting
Started Guide you received with the switch.
To Set Up and Install the Switch in Your Network
Important! Use the HP Procurve Series 4100 Installation and Getting Started Guide
(shipped with the switch) for the following:
■ Notes, cautions, and warnings related to installing and using the switch
and its related modules
■ Instructions for physically installing the switch in your network
■ Quickly assigning an IP address and subnet mask, set a Manager pass-
word, and (optionally) configure other basic features.
■ Interpreting LED behavior.

Selecting a Management Interface
Overview
Overview
This chapter describes the following:
■ Management interfaces for the Series 41008GL switches
■ Advantages of using each interface
Understanding Management Interfaces
Management interfaces enable you to reconfigure the switch and to monitor
switch status and performance. The HP Series 41008GL switches offer the
following interfaces:
■ Menu interface—a menu-driven interface offering a subset of switch
commands through the built-in VT-100/ANSI console—page 1-3
■ CLI—a command line interface offering the full set of switch commands
through the VT-100/ANSI console built into the switch—page 1-4
■ Web browser interface --a switch interface offering status information
and a subset of switch commands through a standard web browser (such
as Netscape Navigator or Microsoft Internet Explorer)—page 1-5
■ HP TopTools for Hubs & Switches--an easy-to-use, browser-based
network management tool that works with HP proactive networking
features built into managed HP hubs and switches
This manual describes how to use the menu interface (chapter 2), the CLI
(chapter 3), the web browser interface (chapter 4), and how to use these
interfaces to configure and monitor the switch.
For information on how to access the web browser interface Help, see “Online
Help for the Web Browser Interface” on page 4-11.
To use HP TopTools for Hubs & Switches, refer to the HP TopTools User’s
Guide and the TopTools online help, which are available electronically with
the TopTools software. (To get a copy of HP TopTools for Hubs & Switches
software, see the Read Me First document shipped with your switch.)

■ Provides quick, easy management access to a menu-driven subset of
switch configuration and performance features:
• IP addressing
• VLANs and GVRP
• Port Security
• Port and Static Trunk Group
• Stack Management
• Spanning Tree
• System information
• Passwords
• SNMP communities
• Time protocols
The menu interface also provides access for:
• Setup screen
• Event Log display
• Switch and port
status displays
■ Offers out-of-band access (through the RS-232 connection) to the
• Switch and port statistic and counter
displays
• Reboots
• Software downloads
switch, so network bottlenecks, crashes, lack of configured or correct IP
address, and network downtime do not slow or prevent access
■ Enables Telnet (in-band) access to the menu functionality.
■ Allows faster navigation, avoiding delays that occur with slower
display of graphical objects over a web browser interface.
■ Provides more security; configuration information and passwords are
not seen on the network.
