This chapter describes the following:
■ Management interfaces for the Switch 4108GL
■ 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 Switch 4108GL offers 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
1-2
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.)

■ 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.

■ 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

Hubs & Switches
You can operate HP TopTools from a PC on the network to monitor traffic,
manage your hubs and switches, and proactively recommend network
changes to increase network uptime and optimize performance. Easy to install
and use, HP TopTools for Hubs & Switches is the answer to your management
challenges.

Figure 1-4. Example of HP TopTools Main Screen
HP TopTools for Hubs & Switches enables greater control, uptime, and
performance in your network:
■ For networked devices
• Enables fast installation of hubs and switches.
• Enables you to proactively manage your network by using the Alert
Log to quickly identify problems and suggest solutions, saving valuable time.
Advantages of Using HP TopTools for Hubs & Switches
Selecting a Management Interface
• Notifies you when HP hubs use “self-healing” features to fix or limit
common network problems.
• Provides a list of discovered devices, with device type, connectivity
status, the number of new or open alerts for each device, and the type
of management for each device.
• Provides graphical maps of your networked devices, from which you
can access specific devices.
• Identifies users by port and lets you assign easy-to-remember names
to any network device.
• Enables you to configure and monitor HP networked devices from
your network management PC, including identity and status information, port counters, port on/off capability, sensitivity thresholds for
traps, IP and security configuration, device configuration report, and
other device features.
• Enables policy-based management through the Quality of Service
feature (QoS) to establish traffic priority policies for controlling and
improving throughput across all the HP switches in your network that
support this feature.
■ For network traffic:
• Watches the network for problems and displays real-time information
about network status.
• Shows traffic and “top talker” nodes on screen.
• Uses traffic monitor diagrams to make bottlenecks easy to see.
• Improves network reliability through real-time fault isolation.
• Lets you see your entire network without having to put RMON probes
on every segment (up to 1500 segments).
■ For network growth:
• Monitors, stores, and analyzes network traffic to determine where
upgrades are needed.
• Uses Network Performance Advisor for automatic traffic analysis
and easy-to-understand reports that give clear, easy-to-follow plans
for cost-effectivly upgrading your network.

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
Using the Menu Interface
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
• System parameters
• IP addressing
• Time protocol
• Ports
• Trunk groups
■ View status, counters, and Event Log information
■ Update switch software
■ Reboot the switch
• A network monitoring port
• Stack Management
• Spanning Tree operation
• SNMP community names
• IP authorized managers
• VLANs (Virtual LANs) and
GVRP
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 “Configuring Username and Password Security” on page 9-3.
Menu Interaction with Other Interfaces.
■ The menu interface displays the current running-config parameter set-
tings. You can use the menu interface to save configuration changes made
in the CLI only if the CLI changes are in the running config when you save
changes made in the menu interface. (For more on how switch memory
manages configuration changes, see Chapter 5, “Switch Memory and
Configuration”.)
■ A configuration change made through any switch interface overwrites
earlier changes made through any other interface.
■ The Menu Interface and the CLI (Command Line Interface) both use the
switch console. To enter the menu from the CLI, use the

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.
