About Hub Management Interfaces
This chapter describes the following topics:
■understanding hub management interfaces for manageable HP 10Base-T Hubs
■advantages of using each interface
Understanding Hub Management Interfaces
The interfaces enable you to reconfigure the hub and to monitor hub status
and performance.
Manageable HP 10Base-T Hubs provide the following interfaces:
■the Web Browser Interface --an interface that can be accessed using a
standard Web browser (Netscape Navigator or Microsoft Internet
Explorer)
■the hub console--an ASCII console interface
■HP AdvanceStack Assistant (ASA)--a Microsoft Windows and Unix SNMP
graphical user interface
Note The interfaces only apply to the manageable HP 10Base-T Hubs:
■HP J3301A 10Base-T Hub 12M
■HP J3303A 10Base-T Hub 24M
Each interface consists of a series of management features, accessed either
through a menu-driven screen system or a split Window with tab navigation,
both that begin at a home environment. Each approach has its advantages that
are described in the next sections.
See chapter 2 for information on connecting up and using the hub console.
Chapter 4 tells you how to use the Browser Interface. Chapter 6 is a manage-
ment screen reference for both the Browser Interface and the hub console.
For coverage of HP AdvanceStack Assistant (ASA), see the HP AdvanceStack
Assistant User’s Guide or the online help available with that product. HP ASA
comes on a separate CD-ROM with the HP 10Base-T Hubs that have built-in
SNMP management capabilities.

Interfaces
Advantages of Using the Browser Interface
The following are advantages of using the Browser Interface:
■easy access of the hub from anywhere on the network, if you know the
device IP address
■familiar browser interface--locations of window objects consistent
with known standard
■faster configuration, avoiding cycling through a series of prompts—
enables less keystrokes, using mouse clicking for navigation; no terminal
setup and console menu access necessary
■many features have all their fields in one screen so you can view all
values at once (the console scrolls through a series of prompts)
■more visual cues, using colors, status bars, device icons, and other
graphical objects to represent values rather than numeric values
■display of acceptable ranges of values available in configuration list
boxes
■port security configuration available
Advantages of Using the Hub Console Interface
The following are advantages of using the hub console:
■more comprehensive set of features to work with than the Browser
Interface
■out-of-band access (through RS-232 connection) to hub, so is not
affected by network bottlenecks, crashes, and downtime
■management access configuration, for example, creating an IP
address, and setting Community Names and Authorized Managers
■several environment access variables available for setting, for
example Web and Telnet access
■rebooting the hub is available
■faster navigation, avoiding having to wait for slower display of graphical
objects over a browser interface

HP AdvanceStack Assistant
The manageable HP 10Base-T Hubs enable you to use HP AdvanceStack
Assistant (HP ASA). Operate HP ASA from a PC on the network to monitor
traffic and manager your hubs and switches. Easy to install and use, HP ASA
(formerly HP Interconnect Manager) is the answer to your management
challenges.
Network Devices:
■Enables fast installation of hubs and switches.
■Notifies you when HP hubs and switches use “self-healing” features to fix
or limit common network problems.
■Identifies users by port and lets you assign easy-to-remember names to
any network device.
■Enables you to configure and monitor network devices from your PC.

Overview of the Hub Console
The hub console interface enables you use a PC, running a terminal emulator,
or a standard ASCII terminal to do the following:
■modify the hub’s configuration
■configure the hub with an IP address that enables the hub to be managed
from an SNMP-based network management station, through the hub’s
Browser Interface, described in chapter 4, “Running the Browser Inter-
face”, or through Telnet access to the console interface.
■control console security by configuring passwords
■monitor the hub and its port status
■monitor the network activity through a set of counters
■download new software to the hub
Note The 10Base-T hubs are “plug-and-go” network devices. They are shipped with
a factory default configuration that will work for most network situations. All
the hub ports are enabled, and the DHCP/BOOTP is enabled so the hub can
automatically acquire an IP address from a properly configured DHCP or
BOOTP server.
For this basic hub operation, it is not necessary to use the console, but you
can use the console for the uses listed above.
Starting a Hub Console Session
The hub console interface can be run on a PC that has a terminal emulator
program, or on a standard ASCII or ANSI terminal. You can connect the
console to the hub in the following ways:
■directly, through an out-of-band RS-232 serial connection (using a serial
cable)
■remotely, using an out-of-band modem connection
■over the network (in-band) through a Telnet session (requires that the hub
have an IP address)

Starting a Session Through a Direct Serial Connection
To serially connect a console to a hub, follow these steps:
1. Connect an a PC emulating an ASCII terminal, or a standard ASCII
terminal to the Console port on the hub using the serial cable supplied
with your hub. (For pin-outs on the cable and Console port connector, see
the Cables and Connectors appendix in the HP 10Base-T Hubs Installa-
tion Guide.) If the PC or terminal has a 25-pin serial connector, first attach
a 9-pin to 25-pin “straight-through” adapter at one end of the console cable
and attach that end to the terminal.
2. Power on the PC and start the terminal emulation program, or power on
the terminal. Configure the terminal emulator or terminal as follows:
• ASCII, ANSI, or VT-100 emulation or terminal
• 8 bits per character
• 1 stop bit
• no parity
• Xon/Xoff flow control
• a baud rate of 115200, 57600, 38400, 19200, 9600, 4800, 2400, or 1200.
3. Press [Enter] a few times until the console displays some hub version
information followed by the message:
Type MENU to access the ASCII menu system
or HE or ? for help on console commands.
and the => prompt is displayed. The baud rate for communication
between the hub and the terminal is set automatically when you press
[Enter].
Note: If you have previously set a username and password for the console, you will
first be prompted to enter those values. For more information on the password
response process, see “Responding to an Enter username Prompt” at the end
of this chapter.
You are now in the command prompt region of the console interface. You can
enter HE at the prompt to see what commands are available. To enter the
console menu system, enter MENU at the prompt.
For more information on the commands, see “The Command Prompt Region”
on page 2-7. For information on the console menus, go to the section, “The
Console Menu System” on page 2-9.

Starting a Session Through a Modem Connection
To establish a remote session, using a pair of modems and terminal, follow
these steps:
1. Use full-duplex, asynchronous (character-mode) modems only. For the
list of supported modems and their initialization strings, go to the HP
networking products web page, http://www.hp.com/go/network_city.
Then, select Support and from the Support page, select 10Base-T hubs.
On the 10Base-T hubs page, select Modem Configuration.
2. Initialize both modems according to the initialization strings found on the
web page.
3. Connect the modem for the hub end to the hub’s Console port using a
“straight-through” RS-232-C modem cable. (For pin-outs and recom-
mended cables see the “Cables and Connectors” appendix in your HP
10Base-T Hubs Installation Guide.
4. At the remote site, connect the modem for the console end to the serial
port on the PC or terminal.
5. Make sure the terminal and modems are functioning properly, then estab-
lish the link between the console’s modem and the hub’s modem according
to the modem instructions. See your modem manufacturer’s configuration
guide for details.
6. Press [Enter] a few times until the console displays some hub version
information followed by the message:
Type MENU to access the ASCII menu system
or HE or ? for help on console commands.
and the => prompt is displayed. The baud rate for communication
between the hub and the terminal is set automatically when you press
[Enter].
Note: If you have previously set a username and password for the console, you will
first be prompted to enter those values. For more information on the password
response process, see “Responding to an Enter username Prompt” at the end
of this chapter.
You are now in the command prompt region of the console interface. You can
enter HE at the prompt to see what commands are available. To enter the
console menu system, enter MENU at the prompt.

Starting a Session Through a Telnet Connection
The HP 10Base-T Hubs support accessing the hub console over Telnet.
Note Running a Telnet session with the hub requires that the hub first be configured
with an IP address. If you have not set an IP address for your hub, go to one
of the previous two procedures to first start an out-of-band console session
through which you can set an IP address on the hub. The hub ships with DHCP/
BOOTP enabled, though, so if you have a properly configured server on your
network, the hub will automatically acquire an IP address from the server.
To establish a Telnet session, follow these steps:
1. Verify that the hub has been configured with an IP address, and that it is
accessible through IP from your PC or workstation. (You can use the Ping
command from your PC to verify the hub accessibility.) Go to the IP
Address reference page in chapter 6 for details on setting an IP address.
2. Enter the command telnet followed by the IP address or system name
of the hub, for example:
telnet 192.1.1.10
or
telnet your_hub
(Your Telnet syntax depends on your TCP/IP software or your terminal
server. You can use a system name if you have name resolution system
such as Domain Name Server--DNS.)
The console then displays some hub version information followed by the
message:
Type MENU to access the ASCII menu system
or HE or ? for help on console commands.
You are now in the command prompt region of the console interface. You can
enter HE at the prompt to see what commands are available. To enter the
console menu system, enter MENU at the prompt.
For more information on the commands, see “The Command Prompt Region”
on page 2-7. For information on the console menus, go to the section, “The
Console Menu System” on page 2-9.
To end the Telnet session, select Logout from the console Main menu to
terminate the console session, and then use your Telnet application’s
command to close or quit the Telnet session.

Using the Hub Console
The hub console is an easy to use, intuitive interface that prompts you for
input and guides you through any configuration. The hub console consists of
two regions as described in the next section.
The Console’s Two Regions
The hub console interface has two regions:
■the Command Prompt region which you enter at first. This region
enables you to perform tasks by issuing commands. For details on using
commands in this region, see Table 2-1.
■the Menu System region which you access by entering ME from the
command prompt. The menus enable you to configure hub, port, and
network settings through screens that contain fields and prompts. See
“The Console Menu System” later in this chapter, and for details on each
of the menus in this region, see chapter 6.
