■ Management interfaces for the Switches 2512/2524
■ Advantages of using each interface
Selecting a Management
Understanding Management Interfaces
Management interfaces enable you to reconfigure the switch and to monitor
switch status and performance. The HP Switches 2512/2524 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 4-12.
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
• Security
• Port and Static Trunk Group
• Stack Management
• Spanning Tree
• System information
• Passwords and other security features
• SNMP communities
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.

Figure 1-3. Example of the HP Web Browser Interface
■ Easy access to the switch from anywhere on the network
■ Familiar browser interface--locations of window objects consistent
with commonly used browsers, uses mouse clicking for navigation, no
terminal setup
■ Many features have all their fields in one screen so you can view all
values at once
■ More visual cues, using colors, status bars, device icons, and other
graphical objects instead of relying solely on alphanumeric values
■ Display of acceptable ranges of values available in configuration list
boxes

Overview
Overview
This chapter describes the following features:
■ Overview of the Menu Interface (page 4-1)
■ Starting and ending a Menu session (page 2-3)
■ The Main Menu (page 2-7)
■ Screen structure and navigation (page 2-9)
■ Rebooting the switch (page 2-12)
The menu interface operates through the switch console to provide you with
a subset of switch commands in an easy-to-use menu format enabling you to:
■ Perform a "quick configuration" of basic parameters, such as the IP
addressing needed to provide management access through your network
■ Configure these features:
• Manager and Operator passwords
Using the Menu Interface
• System parameters
• IP addressing
• Ports
• One trunk group
■ View status, counters, and Event Log information
■ Download new software system
■ Reboot the switch
• A network monitoring port
• Stack Management
• Spanning Tree operation
• SNMP community names
• IP authorized managers
• VLANs (Virtual LANs)
For a detailed list of menu features, see the "Menu Features List" on page 2-14.
Privilege Levels and Password Security. HP strongly recommends that
you configure a Manager password to help prevent unauthorized access to
your network. A Manager password grants full read-write access to the switch.
An Operator password, if configured, grants access to status and counter,
Event Log, and the Operator level in the CLI. After you configure passwords
on the switch and log off of the interface, access to the menu interface (and
the CLI and web browser interface) will require entry of either the Manager
or Operator password. (If the switch has only a Manager password, then
someone without a password can still gain read-only access.) For more
information on passwords, see "Using Password Security" on .

menu command.
Starting and Ending a Menu Session
You can access the menu interface using any of the following:
■ A direct serial connection to the switch’s console port, as described in the
installation guide you received with the switch
■ A Telnet connection to the switch console from a networked PC or the
switch’s web browser interface. Telnet requires that an IP address and
subnet mask compatible with your network have already been configured
on the switch.
■ The stack Commander, if the switch is a stack member
Using the Menu Interface
Note This section assumes that either a terminal device is already configured and
connected to the switch (see the Installation Guide shipped with your switch)
or that you have already configured an IP address on the switch (required for
Telnet access).

How To Start a Menu Interface Session
In its factory default configuration, the switch console starts with the CLI
prompt. To use the menu interface with Manager privileges, go to the Manager
level prompt and enter the
1. Use one of these methods to connect to the switch:
• A PC terminal emulator or terminal
• Telnet
(You can also use the stack Commander if the switch is a stack member.
See "HP ProCurve Stack Management" on ).
2. Do one of the following:
• If you are using Telnet, go to step 3.
• If you are using a PC terminal emulator or a terminal, press [Enter] one

or more times until a prompt appears.
Password: _
Using the Menu Interface
Type the Manager password and press [Enter]. Entering the Manager
password gives you manager-level access to the switch. (Entering the
Operator password gives you operator-level access to the switch. See
"Using Password Security" on .)
• If no password has been configured, the CLI prompt appears . Go to
the next step.
4. When the CLI prompt appears, display the Menu interface by entering the
menu command. For example:
