■ 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
workstation and tha t your wor k station is configured to recognize the CDROM drive.
Consult the README file on the HP Hub & Switch Management CD for
installation procedures.

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
■ client/se rver archi tectur e enabli ng proces ses to be run o n other workst a-
tions
For more information on HP OpenView platform operation and functions,
refer to the HP OpenView Network Node Manager documentation.

Introduction to HP Hub &
Definitions, Processes, and Files
The basic concepts and processes of management for networks are
described briefly in the following paragraphs.

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 Shells Use These Commands
/bin/ksh or /bin/shPATH=$PATH:/opt/OV/bin:/usr/sbin
export PATH
/bin/csh setenv PATH “$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 shells Use these commands
/bin/ksh or /bin/shDISPLAY=hostname:0.0
export DISPLAY
Running HP Hub & Switch
/bin/csh setenv 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.

temporary file. To run ovw in the background and to redirect error
messages to a temporary file, type
ovw > /tmp/ovw.log 2>&1 &
This starts up the entire product set you have installed. The graphical
network map will be generated in a window, with the HP Hub & Switch
Management menu items available in the pull-down menus from the
menu bar.

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.
