■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 Switches 1600M/2424M/4000M/8000M offer the following interfaces:
■the web browser interface --an interface that is built into the switch and
can be accessed using a standard web browser (such as Netscape
Navigator or Microsoft Internet Explorer). For specific requirements, see
“Web Browser Interface Requirements” on page 3-2.
■the switch console—a VT-100/ANSI console interface built into the switch
■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 (included on a CD with
the switch at no extra cost)

Selecting a Management
Interface
Each interface consists of a series of management features, accessed either
through a menu-driven screen system or a split Window with tab navigation.
Each approach has its advantages that are described in the next sections.
This manual describes how to use the web browser interface (chapter 3) and
the switch console (chapter 4), and how to configure the switch using either
interface (chapter 6).
To use HP TopTools for Hubs & Switches, refer to the HP TopTools User’s
Guide and the TopTools online help, both of which are available on the
CD-ROM shipped with your HP switch. For information on the methods for
accessing browser interface Help, refer to “Online Help for the Web Browser
Interface” on page 3-10.

Configuring an IP Address on the Switch
This chapter helps you to quickly assign an IP (Internet Protocol) address and
subnet mask to the switch. In the factory default configuration, the switch
does not have an IP address and subnet mask, so it can be managed only by
using a direct connection to the switch console.
2
Configuring an IP (Internet Protocol) address and subnet mask enables the
switch to operate as a managed device in your network, giving you in-band
(networked) access to these interfaces:
■HP web browser interface built into the switch
■HP TopTools for Hubs & Switches—SNMP-based network management
software shipped with the switch
■the switch console through a telnet connection
For a listing of switch features available with and without an IP address, refer
to “How IP Addressing Affects Switch Operation” on page 6-8.
For more information on this topic, refer to “IP Configuration” on page 6-4.
NoteThe IP address and subnet mask assigned for the switch should be compatible
with the IP addressing used in your network. If your network is a standalone
network, your IP addressing and subnet mask scheme can be set up in any
way that meets your local needs. However, if you will be connecting your
network to other networks that use globally assigned IP addresses, refer to
“Globally Assigned IP Network Addresses” on page 6-13.

Methods for Configuring an IP Address
and Subnet Mask
If the switch has not already been configured with an IP address and subnet
mask compatible with your network, use either of the following two methods
to do so:
■Manually through the switch console: This is the easiest method if you
have direct-connect or modem access to a terminal emulator on a PC
(such as HyperTerminal in Windows 95 or Windows NT), or a direct
connection to a VT-100 terminal. Refer to “Manually Configuring an IP
Address” below.
■Configure your DHCP/Bootp server to support the switch: By
default, the switch is configured to acquire an IP address configuration
from a DHCP or Bootp server. To use DHCP/Bootp, refer to “DHCP/Bootp
Operation” on page 6-9.

Configuring an IP Address
Manually Configuring an IP Address
This section describes how to use the switch console to configure an IP
address. The following assumes that no VLANs have been configured on the
switch.
NoteIn its factory default configuration, all ports on the switch belong to one,
default virtual LAN (VLAN), and only one IP address is needed. If you
configure the switch with more than one VLAN, each VLAN may have its own
IP address. For more on VLANs, refer to “Port-Based Virtual LANs (VLANs)”
on page 6-51.
