Feature s of HP Hub & Switch Managem ent
■Scalable solution s fro m 10 Mbps to Gigabit Ethernet
■Blocks unwanted traffic with Protocol Filtering
HP Proactive Networking products save time, money and increase productivity. The agent-enabled, web-based management component of Proactive
Networking is embedded in newly introduced HP managed hubs and switches.
It consists of a Java-based W eb agent and an embedded web server. In the past,
if you wanted to see a graphical representation of your network or get devicespecific informa tion, you had to fir st load management s oftware on a specif ic
station and then be at that station to view the screen s.
Y ou can now use most W e b browsers that supports Java and frames. There i s
no need to learn a new applicati on . You see the same interface w ith the s ame
look and feel —Java is operating-system independent. You can use a Web
browser on any networked computer, day or night, to configure, control, and
monitor networking devices (managed hubs and switches), and to query faults
from any of these devices. You will immediately see the reduced cost of
ownership, since the devices can be managed with minimal effor t any time,
anywhere, and with any platform.
Using your Web browser, you can now perform network management functions for several HP devices .
Note: The device must have an IP addr ess in order to be managed with
a browser. The management station must also have an IP address.

each additional ovw session that you expect to run.
Required Networ k Config ura t ion
The installation starts the automatic discovery and layout of the network
map, based on your internetwork's IP addressing scheme. This depends on
the following:
■Correct IP addressing. The IP addresses and subnet masks must be
correctly conf igu red on the manager station, and on all routers and
gateway hosts that support SNMP . Otherwise, the automatically generated
map could contain incorrect networks with nodes from outside the administrative domain.
■Network design that aids isolation of network faults and traffic, by doing
the following:
•Logically subdividing an internetwork into manageable-sized
networks and subnetworks, using routers, gateway hosts and IP
subnet addressing.
•Physically subdividing networks and subnetworks into manageablesized segments using hubs, bridges, and gateway hosts. HP recommends that the segments have no more than 200 nodes each.
■SNMP-based, MIB-I (RFC 1156) or MIB-II (R FC 1213 ) compl ian t agen ts
running on management stations, routers, and gateway hosts at a
minimum, and running on bridges and hubs for manageable segments.
This ensures speed and accu ra cy of ma p generation.
■All HP 9000 Systems (manager statio ns or hosts) that are running HP-UX
version 10.20 or HP-UX version 11.00 should also be running the HP
OpenView SNMP Agent software as part of their networking software.
■All managed HP devices should contain a supported version of agent
firmware.

Before Installing HP Hub & Switch
Management
Before you can begin installing HP Hub & Switch Management, you must
have successfully completed installing your Network Node Manager
product. See the HP OpenView Network Node Manager Products Installation Guide for instructions on installing the HP Network Node
Manager and obtaining your software license.
You may set up multiple manager stations on your network. Each manager
on which you install the manager product set does its own polling, so the
manager traffic on your network will increase i n proportion to the number of
managers.
Note: This applies only if you buy multiple copies. Your license only
entitles you to install one copy.
If you are installing this product set on a workstation with an existing
application, be sure you first exit any ovw sessions currently running, then
stop all HP OpenView processes using the ovstop command (available to
root user).

Note: It is also a good practice to make a backup of your current
OpenView application (especially your network map) before
proceeding with the installation of new applications.
Installation Directories
The HP Hub & Switch Management product is installed in the following
directories:
•/var/opt/HPASA
•/opt/HPASA
In compliance with the OSF standards, the /opt/HPASA directories hold the
read-only files, which include all the executables, libraries, release notes,
and Device Model Files. The /var/opt/HPASA directories contain the
writeable directories such as product data directories. Be sure you have the
required amount of free disk space before you install the products. You can
make one of the following arrangements for the required space:
•having the required amount of disk space in /opt and /var
•mounting a dedicated volume for /var/opt/HPASA and
/opt/HPASA
•making /var/opt/HPASA and /opt/HPASA symbolic links to a
file system with enough disk space.
The management system must have both manager and agent software
installed.
Make sure the drive that you will be loading fr om is connected to the

HP Hub & Sw itch Management Overv iew
HP Hub & Switch Management for OV-UX is a network management
application that al lo ws yo u to manage and control Hewlett-Packard (HP)
hubs, bridges, and switches on a TCP/IP network. HP Hub & Switch
Management runs on the HP OpenView platform, which allows multivendor
enterprise-wide networ k management. For communications with managed
devices, Hub & Switch Management uses the Simple Network Management
Protocol (SNMP)—an industry standard network management
communications protocol.

HP OpenView Netw ork Management Platform
HP OpenView Network Management
Platform
HP OpenView is a “platform” for network management applications. As a
platform, it allows multiple network management applications that are
OpenView compliant—such as HP Hub & Switch Managemen t—to share
platform functionality and a common display.
Using the HP OpenView, Network Node Manager provides many shared
management functio ns, wh ich include:
■automatic discovery and mapping of IP networks and objects
■dynamic submap creatio n
■map navigation Tool Bar
■Quick Navigator
■a map zoom viewer
■device polling to monitor devices on an OpenView map
■an event notificati on and loggin g system
■generic SNMP device management
■graphing and logging of traffic

Switch Management
Introduction to HP Hub &
Definitions, Processes, and Files
The basic concepts and processes of management for networks are
described briefly in the following paragraphs.
3-2
Introduction to HP Hub & Switch Management
Definiti ons, Processes, and Files
SNMP Manager and Agents
HP Hub & Switch Management uses SNMP (Simple Network Management
Protocol) to communicate with managed d evices. SNMP commands are
transmitted and received on the network using the Inte rnet Protocol (IP).
The network management station used to run Hub & Switch Management is
referred to as an SNMP manager system. HP devices with SNMP agents are
called agent systems. Each network management operation requested by
the manager system is executed by one or more agent systems.
The manager system communicates with HP devices to retrieve or modify
management informati on. The devices contain Network Management SNMP
Agent software to support this communication.
Note: For Hub & Switch Management operation, you must set up HP
network devices for SNMP/IP operation. See Appendix A for more
information.
Communit y Na mes for Manager and Agent Interaction
Most SNMP exchanges involve a community name, which can be thought
of as a password for a managed device or gro up of dev ices.
Depending on the device, SNMP get requests for information from a devi ce
agent may require the manager to suppl y a community name that is
configured on the device.
Introduction to HP Hub &
Switch Management
If a password has been specif ically configured on a devic e, th en pa ssword
authentication i s required to perform any SNMP set operations that alter the
configuration or invoke self-test or reset on that device. The manager system
automatically asks you for the password, then puts the encrypted password
in the community name field of subsequent set operations.
Configuring a password on HP devices is recommended but not required. As
described late r in this manual, you can use Hub & Switch Manageme nt to set
a device password.

Running HP Hub & Switch Management
This chapter describes how to start and stop HP Hub & Switch Management.
It includes the following topics:
■Starting the Manager Application
■Verifying Installation of the Manager Product Set
■Stopping and Restarting the Manager Application
Note: Before you begin, you should ensure that the network devices are
properly set up for IP operation. For information on setting up HP
network devices, see
Appendix A
Starting the Manager Application
.

The entire product set that you have installed is started as one application,
“the manager”, on your management station. In other words, HP Hub &
Switch Management starts alon g with Networ k Node Manager.
Starting HP OpenView
Do the following steps to start your product.
1.Add /opt/OV/bin to your path using one of the commands below. Note
that you only need to do this the first time you start the HP OpenView
manager software.
For These ShellsUse These Commands
/bin/ksh or /bin/shPATH=$PATH:/opt/OV/bin:/usr/sbin
export PATH
/bin/cshsetenv PATH “$PATH:/opt/OV/bin:/usr/
sbin”

2.Optionally, execute the /opt/OV/bin/ovstatus command to verify
that the trapd, ovwdb, ovtopmd, and netmon background processes are
running. If the background processes are not running, execute the
/opt/OV/bin/ovstart command. If you are surprised that a background process is not running, run ovstart -v, which gives you more
information. The ovstart command starts the background processes.
(You must be root to perform this step.)
3.If you are not running X Windows (X Windows, HP VUE or HP CDE for
HP-UX syst e ms), start it.
4.Optionally, if you want to redirect your X Windows display to a system
other than the management system:
a.Set your X Windows DISPLAY v ariable on the HP OpenView network
management system using o n e of the comma nds bel o w. Replace
hostname with the host name of the system to which you are
redirecting the display.
For these shellsUse these commands
/bin/ksh or /bin/shDISPLAY=hostname:0.0
export DISPLAY
Running HP Hub & Switch
/bin/cshsetenv DISPLAY hostname:0.0
5.Make sure that the management system has permission to display
windows on hostname. If the management sy stem does not have permission, and if the hostname is using the host-based authorization, use the
xhost command to add the management system to the xhost table on the
hostname system. To do so, on hostname type:
xhost + <managementsystem name>
where managementsystem name i s the host name of the management
system. If the hostname is using the MIT-MAGIC-COOKIE-1
authorization, please refer to the xauth man pages to set up the
.Xauthority file.
6.Start the graphical networ k map (user inter face) by typing:
ovw
ovw is executable by anyone.

Stopping and Restarting the Manager
Application
Stopping the Manager
Stopping the manager consists of:
1.Exiting the manager' s graphical network map and user interf ace, and
2.Optionally stopping the manager's background processes.
To exit from the network map and interface (ovw ), select Exit in the map's
File menu.
Running HP Hub & Switch
If you want the manager to continuously collect data and monitor changes
even when the map and interface are not up (that is, even if you exit from
ovw), do step 1 and not step 2. The background processes—netmon, trapd,
ovwdb, ovtopmd, and snmpCollect—will continue to run and you need only
run /opt/OV/bin/ovw to return to the map and interface. For more
information on these background processes, refer to the HP Open Vie w Network Node Manager Reference manual or read the man page for the
process.
If you want to stop the background processes, use the command /opt/OV/bin/ovstop. Using ovstop without arguments stops all of the
processes—netmon, trapd, ovwdb, ovtopmd, and snmpCollect—in the
correct order.

Characteristics of Bootp an d D C HP. The Bootp protocol is designed for
a network in which each h o st has a permanent network connection. It is not
adaptable to a mobile computing envir o n ment.
The Dynamic Host Configuration Protocol (DHCP) manages the allocation
of TCP/IP configuration information by automatically assigning IP
addresses.When a device connects to the network, it requests an address
from the DHCP server. In dynamic mode, the address is used by the devic e
for a specified period of time. The time period depends on the situation; one
device may only need th e ad d ress for an hour, while another device may use
the same address for severa l da ys. DHCP is more suitable in environments
where the number of IP addresses needed exceeds the number available. It
also allows a device to obtain i ts con f igu ration information, such as the IP
Address and Subnet Mask, in one message, reducing the demand on the
network.

The bar graph gives a quic k overvi ew of the per formance o f the swit ch. Eac h
bar shows the highest percentage of transmitted (TX) or recei ved (RX)
traffic utilization for that port in the last five seconds .
The graph area proportionally depicts three attributes for each port:
■Unicast packets - The percent utilization for packets that were not
addressed to a multicast or broadcast address.
■Non-Unicast packets - The percent utilization of received non-unicast
packets (both b roadcast and multicas t). If there is a broadcast sto rm, only
the port receiving these packets shows high utilization, lettin g you quickly
pinpoint the problem.

Configuration - IP Configuratio n
Select the way that you want IP addresses configured for your network:
■Manual - Set the IP address through the console.
■Disabled - IP is disabled, there is no access to management or telnet. Not
Recommended.
■Use Bootp - The Bootp (or DHCP) protocol sets the IP address automat-
ically.
If you select Manual configuration, you can change the IP address, a subnet
mask, and a default gateway for the device.
Some switches let you configu re an IP address for every VLAN you have
created.

The Dynamic Host Configuration Protocol (DHCP) manages the allocation
of TCP/IP configuration information by automatically assigning IP
addresses.When a device connects to the network, it requests an address
from the DHCP server. In dynamic mode, the address is used by the devic e
for a specified period of time. The time period depends on the situation; one
device may only need th e ad d ress for an hour, while another device may use
the same address for severa l da ys. DHCP is more suitable in environments
where the number of IP addresses needed exceeds the number available. It
also allows a device to obtain i ts con f igu ration information, such as the IP
Address and Subnet Mask, in one message, reducing the demand on the
network.
A static IP address is a unique address that is assigned to one client only.
Static addresses are used for an extended time period.

Using VLANS
Virtual LANs, or VLANs, are generally defined as broadcast domains created
with software rather than being a functio n of the hardware. They can be
viewed as a group of end nodes, possibly on different physical LAN
segments, that can communicate with each other.
As networks expand, more routers are needed to separate users into
broadcast domains. Latency degrades network performance, and is a special
problem for multimedia applications. Switches using VLANS create the same
division of the network into broadcast domains, but do not have the latency
problems of a router. Switches are also a more cost-effective solution. You
can create virtual LANs by assigning selected ports of your HP switch to a
VLAN.
The benefits of VLANs include:
■Grouping users into logical networks for increased performance
7-11
Managing Switches
Managing Switches
Configuration
■Providing an easy, flexible, less cos t ly way to modify logical gr oups in
changing environments
■Preserving curren t investment in equipment an d cabling
■Allowing administrators to “fine tune” the network
■Providing independence from the physical topology of the network
VLANs make large networks more manageable. You can group users
according to some shared characteristic, such as a common busin ess
function or a common protocol. A single switch may have severa l
independent VLANs within it.
Note: VLANs must be created with the device console.
Configuration - Device Features

of these features:
■Automatic Br oadcast Cont rol (ABC)
■Multicast Filtering (IGM P)
■Spanning Tree
Managing Switches
Automatic Broadcast Control (ABC)
Automatic Broadcast Control (ABC) is a feature that controls broadcasts
through IP/IPX Broadcast Reduction. IP/IPX Broadcast Reduction reduces
the number of broadcasts propagated through the network.
Using ABC, th e switch acts as a proxy se rv er, replying to Address Resolut io n
Protocol (ARP) requests, Nearest Server Query (NSQ) requests, and
GetLocalTarget reques ts on behalf of the destination node . An ARP cache
(learned address table) is created for each subnet allowing the switch to
proxy reply with the resolved MAC address instead of forwarding the
requests out all ports. This limits the broadcasts within the switching
domain. The Service Advertising Protocol (SAP) table performs the same
function in an IPX network. By using these tabl es, the switch can resolve
addresses for any node in the network that it already knows about.
Routing Information Protocol. The switch also intercepts Routin g
Information Protocol (RIP) and SAP broadcasts and forwards these only to
ports where routers and servers have been de tected . This also reduces the
number of broadcasts on the network.
7-12
Managing Switches
Configuration
For example, if User A sends out a broadcast message to connect to its
server, the request is sent out of all ports on the swit ch . When the serv er
responds to User A, the switch intercepts the response and learns that the
server is on that port. When User B sends a request to the same server, the
switch already knows which port that server is on and sends that
information to User B, just as if the server had responded to the request.
User B’s request is not broadcast out any of the switch ports.
Enabling Broadcast Control for IP
The IP protocol uses Address Resolution Protocol (ARP) packets to find the
MAC address of a node that corresponds to the network layer address. When
Broadcast Contr ol is enab led, the switch intercepts the ARP packet on its
way to the destination node. If this destination is unknown to the switch, the
switch floods the ARP request to all ports. When the destination port
responds, the switch stores information about the destination MAC address
and layer 3 address in its ARP cach e. T hi s info rmation allows the switch to
proxy a reply containing the MAC address of a destination to the source of
an ARP request. The source can then send a unicas t pac ket directly to the
destination. The amount of broadcast traffic has been decreased.
Automatic IP RIP Control. To further reduce broadcast traffic, you can
check Automatic IP RIP Control. IP RIP packets are sent out perio d ically
(every 30 seconds) to distribute routing information. By enabling Automatic
IP RIP Control, the switch will only forward RIP packets out the ports on
which RIP packets have been received. Since routers are the onl y de vices
that generate RIP packets, this ensures that RIP packets are only sent out
ports with routers attached to them. When this feature is not enabled, IP RIP
packets are forwarded to all ports.
Managing Switches
Enabling Broadcast Control for IPX
The IPX protocol broadcasts all of its known routes and services every
minute by using IPX, RIP and Service Advertising Protocol (SAP) packets.
When servers are booted up, they advertise their services using SAP. These
frames must be forwarded by routers, which maintain a database of this
information, allowing clients on the network to obtain the internetwork
addresses of the servers where they can access services.
Automatic IPX RIP/SAP Control. To further reduce network traffic, you
can check the Automatic IPX RIP/SAP Control check box. The switch will
intercept RIPs and SAPs, broadcasting them only to ports where IPX routers
or servers have been detected, or to ports that have been configured to
7-13
Managing Switches
Configuration
transmit RIPs or SAPs. When this feature is not enabled, IPX RIP/SAP
packets are forwarded to all ports.
Automatic IP Gateway Configuration
When Automatic IP Gateway Configuration is enabled, the swi t ch wil l
modify replies from the DHCP server so that the Default Gateway IP address
of a client becomes the client’ s own IP address. This is useful in a
multinetted environment (where more than one IP network is configured in
a single broadcast domain).
See Routing Information Protocol.
Internet Gro up Management Pr otocol (IGMP)
Multimedia and email applications need the ability to communicate to
multiple destinations efficiently. IP multicasting allows host s to d yn amically
register for sending or receiving multicast traffic.
The Internet Group Management Protocol is a method for automatically
controlling multicast traffic through the network. Using multicasting,
applications can send one copy of a packet addressed to a group of
computers that wish to receive it. This method is more efficient than sending
a separate copy to each node. Other advantages of multicasting include:
Managing Switches
■information delivered in a timely , synchronized manner because all desti-
nation nodes receive the same packet
■information can be sent to destinations whose addresses are unknown
■reduces the number of packets on the network because only one multicast
packet is sent.
IGMP uses multicast queriers and hosts that support IGMP to manage
multicast traffic on the network. It specifies how the host informs the
network that it is a member of a multicast group. A set of queriers and hosts
that send and re ceive data from the same set of sources is a multicast group.
The HP switches have a standards-based IGMP implementation. The
switches process IGMP packets by learning which of the switch’s interfaces
are linked to hosts that are members of multicast groups and multicast
routers. It limits multicast traffic by monitoring the IGMP traffic to learn
which hosts are in which multicast groups, then allowing IP multicast traffic
to be sent only to ports with valid host group members.
When a switch receives an IGMP packet, it u pdates the internal IP multic ast
forwarding table with the IGMP membership read from that packet. The
7-14
Managing Switches
Configuration
switch then sends the packet to the ports with members of the destination
multicast group.
Special multicast routers/queriers communicate by using three message
types - query, report, and leave group. The query message, sent by a querier,
is used to discover which network interfaces belong to a multicast group.
Each host responds to th e query message with a report m essage that tel ls the
querier the host is a member of the multicast group. The host also can send a
report message to join a group or a leave message to leave a group.
Note: Using the console you can designate specific ports to always or
never forward multicast packets.
Forward with High Priority
When “Forward with High Prior ity” is checked, any IGMP packets received
by the switch will be forwarded in a prioritized manner, preceding packets
with normal priority.
The Spanning Tree Protocol
The Spanning Tree Protocol (IEEE 802.1d) maintains a loop-free topology in
networks with redundant bridges or switches. The spanning tree devices
determine which devices will be active and which will be backups so that no
two nodes in a network have more than o ne active p ath between them at any
time. The Spanning Tree Protocol uses the most efficient path between
segments. If a bridge or switch fails, the other bridges and switches
reconfigure the network automatically. When the problem is repaired, the
bridges and switches automatically return to the original network
configuration.

About Closeup Views
HP Hub & Switch Management provides direct acce ss to HP hub, bridge, and
switch management for devi ces that are no t manageab le with a W e b browser
through graphical co n trol panels, or Closeup Views. If you have switching
hubs, you can also use the Closeup View to create and modify segments in
your network.

Management for Non-
Browserable Devices
A Closeup View is an interactive, visual display of a devi ce. Y o u can use the
Closeup Vie w to obtai n devi ce status, and run Hub & Switch Management
command functions through push-button icons and menus. There is a Closeup
View for most HP managed devices.
There will be differences in the available function icons depending on the
device type. Icons for fun ctions that are not available fo r s ome de vices will
either not be selectable (grayed out) or will not appear. Also, menu options
launched from icons that are not available for some devices either will not
appear , or if they appear, they will not be selectable. For information on device
management funct ions for any particul ar device, refer to the o nline help in the
Closeup View .
For HP AdvanceStack hubs, Closeup Views are available for managing all hubs
on a Distributed Management Chain. Closeup Vi ews for chained hubs that are
without SNMP modules are accessed through the appropriate SNMP-based
hub's Closeup View . F unctions that are not avai lable for chained hubs will not
be selectable.

Agent Firmware Versions
HP Hub & Switch Management communicates with network devices using
SNMP (Simple Network Management Protocol).To access device features,
each network device must conta in a compatibl e version of agent softw are or
firmware.
Note: The latest firmware agents can be obtained from the Support
section of the HP networking W eb page. The URL is:
http://www.hp.com/go/procurve
Verifying Device Agent Versions
You can check the agent version on an HP device using one of the following
methods:
■Use the device's console port interface (a non-network connection).
Y ou can connect a terminal or computer directly to the device or through
a modem. Refer to t he devi ce' s Installation and Reference Guide for use
of the device's RS-232 console port.
•For HP devices, you can use an ASCII terminal or computer wi th
VT 100 terminal emulation.
■Use an available network application (a network connection).

Preparing Network Devices
For HP devices, use an existing version of HP Hub & Switch Management
or other device management utility.
Update the device's softwar e or firmware to the current supported version.
Note: HP Hub & Switch Management may be able to discover devices
that have previo us versions of device agent firmware. However, the use
of some functions may be limited.
Preparing Networ k De vices
For HP Hub & Switch Management to communicate with devices on your
network, the network devices must:
■have SNMP agent firmware th at is compatible with this version of HP Hub
& Switch Management.
■for IP networks, have a unique IP network address.
Note: Hubs and bridges shipped prior to July 1992 must be upgraded.
Appendix A
Basic hub management feature s are avail able for chained Adva nceStack hubs
if they are connected to an SNMP-based hub of the same media type (10BaseT or 100VG) over a Distributed Management chain.
Device Network Addresses
On an IP network, each managed device must have an IP address. If you intend
to run HP Hub & Switch Management on an IP network, you must configure
the IP address for each device you want to manage.
IP addresses are normally co n figured when the device is installed. For
HP hubs, bridges, and switches, IP addresses are configured using the console
port interface. For more details on console port connection and available
commands, see the device 's Installation and Reference Guide.

A-3
Appendix A
Appendix A
Configuring IP Parameters
The network management statio n is co nfigured for IP using the TCP/IP st ack
utilities. To configure a device for IP, you typically connect to the device's
console port and use the cons ol e port in terface. (Refer to the device's installation manual for more information.)
Before you configure the network management station and manageable
devices for IP, make a list of all the device s on the network and what their IP
addresses will be.
Note: Make sure that every device has a unique IP address. Make sure
that all devices on a given IP network number have the same subnet
mask.
The IP configuration parameters are described below.
IP Address . The IP address of the hub, bridge, or switch is written in the
format X.X.X. X, where each X is a d ecimal nu mber betwe en 1 and 254. Every
IP address on a network must be unique.
The default val u e, 0.0.0.0, dis ab les IP communications. Use the default value
only if you are not going to manage the device with HP Hub & Switch
Management and you want to disable IP communicatio n s for that device.
Appendix A
Subnet Mask. The bit mask defines which portion of the IP address is the
subnet address and is written in the format X.X.X.X. The default value is
automatically generated and depends on the class of IP address that you
entered. See your network administrator for the subnet mask address. All
devices on a given IP network number must use the same subnet mask
address.
Primary Default Router . The routing IP address o f the nearest r outer in
your network. The default is 0.0.0.0.
Backup Default Route r. Th e IP address of th e router t o use when the
primary default router is inaccessible. The default value is 0.0.0.0. If there is
no backup router and no primary default router, use the default.
Time To Live . The number of IP routers a packet is allowed to cross before
the packet is di scarded. The d efault value is 32. Increa se thi s value if t he hub,
bridge, or switch is managed from a network management station that is more
than 32 routers away. The maximum allowable value is 255.
Note: For selected devices, such as the HP J2980A AdvanceStack 10/

name “public” on the device to allow the device to be discover ed and
managed by HP Hub and Switch Management. Typically, the
community name on HP hubs and bridges will automatically default to
“public”.
T o confi gure a device for IP network s, use the devi ce's console port inter face.
Refer to t he d evice's Installation and Reference Guide fo r use of the de vice's
RS-232 console port.
Note: For HP hubs, HP Hub & Switch Management can be used to
change IP addresses afte r they have been initially assigned during
installation.
Network Bootp Server
HP EtherTwist Hub Plus/24S and HP AdvanceStack 10Base-T hubs (with
SNMP modules installed) support the use of Bootp (Bootstrap Protocol) to
automatically retrieve their IP config uration from a server on the network. A
device's IP configuration must be configured in a file on the Bootp server.
When the device is powered on, Bootp is used to automatically download the
IP configuration to the device.
■Each device that supports Bootp must have Bootp enabled to retrieve its
IP configuration from the server. The factory default setting is for Bootp
operation to be enabled. You can enable or disable Bootp operation
through the device's console port, or from a network management application (such as HP Hub & Switch Management).
■For more information on IP configuration using Bootp, refer to your
device's Installation and Reference Guide.
