Introduction

This guide will help you use HP Hub & Switch Management for basic manage­ ment of HP network devices.

We assume that you are a knowledgeable HP-UX system and network admin­ istrator, and have supervisory access to your network system and devices. For example, you should know the following:

how to update your HP-UX system with new software

how to kill processes

how to write scripts

how to modify X Window/Motif resources

how to view, search, and edit files

You should understand the functions and correct operation of your network devices, such as hubs, bridges, routers, and switches. Your system should be set up to support the use of the HP OpenView platform and HP Hub & Switch Management. You should already have the appropriate network software running and know how to use your network utilities.

Features of HP Hub & Switch Management

Scalable solutions from 10 Mbps to Gigabit Ethernet

Blocks unwanted traffic with Protocol Filtering

HP Proactive Networking products save time, money and increase produc­ tivity. 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 Web agent and an embedded web server. In the past, if you wanted to see a graphical representation of your network or get devicespecific information, you had to first load management software on a specific station and then be at that station to view the screens.

You can now use most Web browsers that supports Java and frames. There is no need to learn a new application. You see 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 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 effort anytime, anywhere, and with any platform.

Using your Web browser, you can now perform network management func­ tions for several HP devices.

Note: The device must have an IP address in order to be managed with a browser. The management station must also have an IP address.

Required Network Configuration

* The more OpenView Windows (ovw) sessions you run, the more OS configured swap space will be necessary. A good guideline is to configure 25 megabytes of swap space for each additional ovw session that you expect to run.

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 gateway hosts that support SNMP. Otherwise, the automatically generated map could contain incorrect networks with nodes from outside the admin­ 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 manageablesized 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 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.

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)

For HP-UX 11.00 — S700_800 11.00 HP aC++ runtime library components (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).

Removing HP Hub & Switch Management

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 CDROM drive.

Consult the README file on the HP Hub & Switch Management CD for installation procedures.

Removing HP Hub & Switch

HP Hub & Switch Management Overview

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 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.

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

Definitions, Processes, and Files

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. 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 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.

Optional SNMP module for HP 100 VG hubs is J2414A or J2414B

Optional SNMP module for 10Base-T hubs is J2603A/B. HP AdvanceStack 10Base-T hubs provided with SNMP module preinstalled include: HP J2630A (12-port), HP J2631A/B (24-port), HP J2632A/B (48port).

SNMP module J3133A available for J2610B and J2611B.

HP J2980A 10/100 LAN Switch-16 is not supported on IPX networks. To discover this device on an

IP network, the SNMP community name “public” must be configured on the device. 100VG module J2981A and 100BaseTX module J2984A available for HP J2980A.

Note 5 No IPX Network Management support. Note 6 Requires Management Module J3178A. Note 7 Requires Management Module J3210A. Note 8 No Closeup View provided. Use telnet.

Note: HP AdvanceStack hubs can be chained together on a nonnetwork connection called a Distributed Management Chain. For Hub & Switch Management to access a chain of AdvanceStack hubs, at least one hub in the chain must contain an SNMP module. Chained hubs must be of the same media type (100VG or 10Base-T). For more information, refer to the device’s installation and reference manual.

For general management of generic SNMP devices (from HP and other vendors), use the HP OpenView Network Node Manager functions (such as

SNMP Configuration and SNMP MIB Browser).

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 along with Network 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/

PATH=$PATH:/opt/OV/bin:/usr/sbin

sh

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 systems), 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 variable on the HP OpenView network management system using one of the commands below. 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/

DISPLAY=hostname:0.0

sh

export

DISPLAY

/bin/csh

setenv

DISPLAY hostname:0.0

 

 

 

5.Make sure that the management system has permission to display windows on hostname. If the management system does not have permis­ sion, 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 is 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 network map (user interface) by typing:

ovw

ovw is executable by anyone.

Alternatively, you can run ovw in the background to free up the terminal window for other uses. In some cases, ovw prints error messages to standard output and standard error. To capture these messages and to

Stopping and Restarting the Manager

Application

Stopping the Manager

Stopping the manager consists of:

1.Exiting the manager’s graphical network map and user interface, 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.

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 OpenView 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.
