no need to learna new application. Yousee the same interface with the same
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
monitornetworkingdevices(managedhubsandswitches),andtoqueryfaults
from any of these devices. You will immediately see the reduced cost of
ownership, since the devices can be managed with minimal effort anytime,
anywhere, and with any platform.
Using your Web browser, you can now perform network management func-
tions for several HP devices.

Management Station Requirements
Hardware
The following table shows the recommendations for HP 9000 hardware.
Software
The following table shows the software that must be installed, configured,
and verified to run properly prior to installing HP Hub & Switch
Management. These prerequisites assume that you are running a single
HP OpenView Windows (ovw) session.

* The larger your IP network or the more HP OpenView Windows (ovw) sessions you run,
the more memory you will need. A good guideline is 10 megabytes for every additional 500
nodes,or25megabytesofmemoryforeveryadditionalovw sessionthatyouexpecttorun.

Required Network Configuration
Before Installing HP Hub &
Switch Management for OV-
Required Network Configuration
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 configured on the manager station, and on all routers and
gatewayhoststhatsupportSNMP.Otherwise,theautomaticallygenerated
mapcouldcontainincorrectnetworkswithnodesfromoutsidetheadmin-
istrative 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 manageable-
sized segments using hubs, bridges, and gateway hosts. HP recom-
mends that the segments have no more than 200 nodes each.
■SNMP-based, MIB-I (RFC 1156) or MIB-II (RFC 1213) compliant agents
running on management stations, routers, and gateway hosts at a
minimum, and running on bridges and hubs for manageable segments.
This ensures speed and accuracy of map generation.
■All HP 9000 Systems (manager stations orhosts) 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.
* The more OpenView Windows (ovw) sessions you run, the more OS configured swap
space will be necessary. A good guideline is to configure 25megabytes of swap space for
each additional ovw session that you expect to run.

Required Patches
The following patches must be installed before installing HP Hub & Switch
Management for OV-UX. Contact your HP Authorized Dealer or the nearest
HP Sales and Support Office, or download the patches from the HP
Electronic Support Center. The URL is:
http://us-support2.external.hp.com
The two patches are:
■For HP-UX 10.20 — PHSS_15043 S700_800 10.x HP aC++ runtime library
components (A.01.15)
■ForHP-UX11.00—S700_80011.00HPaC++runtimelibrarycomponents
(A.03.10)
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 in 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 from is connected to the
workstation and that your workstation is configured to recognize the CD-
ROM drive.
Consult the README file on the HP Hub & Switch Management CD for
installation procedures.
Removing HP Hub & Switch
Management
If necessary, you can remove products that you installed by using the
command that is appropriate for your operating system. You must be logged
on as root and you must remove them in the reverse order that you installed

This chapter introduces HP Hub & Switch Management and includes the
following topics:
■HP Hub & Switch Management Overview
■HP OpenView Network Management Platform
■Definitions, Processes, and Files
■What Devices Can Be Managed
HPHub&SwitchManagementOverview
HP Hub & Switch Management for OV-UX is a network management
application that allows you 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 network management. For communications with managed
devices, Hub & Switch Management uses the Simple Network Management
Protocol (SNMP)—an industry standard network management
communications protocol.
HP Hub & Switch Management is integrated with HP OpenView Network
Node Manager applications.
When using Hub & Switch Management, you can do the following:
■use HP OpenView functions to automatically discover and display the IP
map (and submaps). HP hubs, bridges, and switches that are set up for
SNMP/IP operation will be displayed as appropriate “connector” devices.
■use your Web browser to launch Device Views for Proactive network
management
■manage HP hub and switch security features
■run network tests to troubleshoot network or device problems

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 Management—to share
platform functionality and a common display.
Using the HP OpenView, Network Node Manager provides many shared
management functions, which include:
■automatic discovery and mapping of IP networks and objects
■dynamic submap creation
■map navigation Tool Bar
■Quick Navigator
■a map zoom viewer
■device polling to monitor devices on an OpenView map
■an event notification and logging system
■generic SNMP device management
■graphing and logging of traffic
■client/server architecture enabling processes to be run on other worksta-
tions
For more information on HP OpenView platform operation and functions,
refer to the HP OpenView Network Node Manager documentation.

SNMP Manager and Agents
HP Hub & Switch Management uses SNMP (Simple Network Management
Protocol) to communicate with managed devices. SNMP commands are
transmitted and received on the network using the Internet Protocol (IP).
The network management station used to run Hub & Switch Management is
referred to as an SNMP manager system. HPdevices 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 information. 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.
Community Names 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 group of devices.
Depending on the device, SNMP get requests for information from a device
agent may require the manager to supply a community name that is
configured on the device.
If a password has been specifically configured on a device, then password
authentication is 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 later in this manual, you can use Hub & Switch Management to set
a device password.
