Features of HP Hub & Switch Management

■ Scalable solutions from 10 Mbps t o Gig ab it Et hernet

■ Blocks unwanted traffic with Protocol Filtering

HP Proactive Networking produc t s 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 webserver.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.

Y ou can now use most W eb browsers that supports Java and frames. There is no need to learn a new application. Y ou see th e same interface wi th 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 networkingdevices (managedhubs andswitches), andto 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 functions 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 t hat 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 configur ed on the manager station, and on all rou t ers and gatewayhosts that supportSNMP . Otherwise, the automaticallygenerated map could contain incorrect networks with nodes from outsidethe administrative domain.

■ Network design that aids isolation of network faults and traffic, by doing

the following:

• Logically subdividing an internetwork into manag eable-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 (RFC 1213) compliant agents

running on management stations, routers, and gateway hosts at a minimum, and running on bridge s and hubs for manageable segments. This ensures speed and accuracy of map generation.

■ All HP 9000 Systems (manager stations or hosts) that a re running HP-UX

version 10.20 or HP-UX ve rsion 11.00 should also be running the HP OpenView SNMP Agent software as part of their ne tworking software.

■ All managed HP devices should contain a supported version of ag en t

firmware.

Before Installing HP Hub & Switch Management

Before you can begin installing HP Hub & Switch Management, you must have successfully completed installing y our 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 sta ti ons on y our network. Each manager on which you install the manager produc t set does its own p olling, 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 instal l 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 curr ent OpenView application (especially your network map) before proceeding with the installation of new applications.

Installation Directories

The HP Hub & Switch Management pr oduct 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 a ll th e 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 arra ngements for the required space:

• having the requi r ed 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 b oth 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.

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 pla t form, which allows multivendor enterprise-wide network man age me nt. For communications with managed devices, Hub & Switch Ma nagement uses the Simple Network Management

Protocol (SNMP)—an industry standar d ne twork management communications protocol.

Introduction to HP Hub &

Switch Managemen t

HP Hub & Switch Management is integrated with HP OpenView Network Node Manager applications.

When using Hub & Switch Manag e me nt, you can do the following:

■ use HP OpenView functions to automatically discover and display the IP

map (and submaps). HP hubs, bridges, and sw it ches 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 networ k

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 & Swit ch 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 de vices on an OpenView map

■ an event notification and logging system

■ generic SNMP device m a nagement

■ graphing and logging of traffic

■ client/server architecture enabling processes to be run on other worksta-

tions

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 Manage ment is referred to as an SNMP manager system. HP devices with SNMP agents ar e 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.

Introduction to HP Hub &

Switch Managemen t

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 fo r t he 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.

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, yo u should ensure that the network devices ar e properly set up for IP operation. For information on setting up HP network devices, see

Starting the Manager Application

Appendix A

The entire product set that you have installed is started as one application,

“the manager”, on your management stat ion. In other words, HP Hub & Switch Management starts along w it h Ne twork 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/ sh

/bin/csh� setenv PATH “$PATH:/opt/OV/bin:/usr/

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

sbin”

2. Optionally, execute the /opt/OV/bin/ovstatus command to verify that the trapd, ovwdb, ovtopmd , and netmo n 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, whic h gi ve s you more information. The ovstart command starts the background proc esses. (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 displa y to a system other than the management system:

a. Set your X Windows

management system using one of the commands below. Replace hostname with the host name of the sy stem to w hich you are redirecting the display.

For these shells Use these commands

DISPLAY

variable onthe HP OpenView network

Running HP Hub & Switch

Management

/bin/ksh or /bin/ sh

/bin/csh setenv DISPLAY hostname:0.0

DISPLAY=hostname:0.0

export DISPLAY

5. Make sure that the management system has permission to display windows on hostname. If the management system 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 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 ter minal

window for other uses. In some cases, ovw prints error messages to standard output and stand ar d 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 interfa ce (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 pr ocesses—netmon, trapd,

ovwdb, ovtopmd, and snmpCollect—w ill continue to run and you need only run /opt/OV/bin/ovw to return to the map and in terface. 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, a nd snmpCollect—in the correct order.

If you select Manual, you must then enter an IP Address, Subnet Mask, Default Gateway, and Time to Live for the device. If you select Bootp/DHCP, the IP address will be assigned automatically.

Switching Hub IP Configuration

For the switching hubs, you must select a segment to configure before you select Manual or Bootp/DHCP. If you select Manual, you must then enter an IP Address, Subnet Mask, Default Gateway, and Time to Live for the device.

Accessing Hub Features

If you select Bootp/DHCP, the IP address will be assigned automatically.

Characteristics of Bootp and DCHP. The Bootp protocol is designed for a network in which each host has a permanent network connection. It is not adaptable to a mobile computing environment.

The Dynamic Host Configuration Prot ocol (DHCP) manages the alloca tion 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 device for a specified period of time. The time period depends on the situation; one device may only need the address for an hour, while another device may use the same address for several days . DHCP is more suitable in environments where the number of IP addresses needed exceeds the number available. It also allows a device to obtain its configuration information, such a s the IP Address and Subnet Mask, in one me ssage, 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.

Configuration - Backup Links

A backup link (hubs only) configures two ports on one hub to create a redundant connection to another device. This provides a connection with fault-tolerant capability for highly reliable networking. One port is designated the primary port; the second port is the backup port. The backup port becomes active only if the primary port becomes i noperativ e. Any of the network ports (twisted-pair, ThinLAN, or AUI/Xcvr) can be used as the primary port or backup po rt.

Graph Area

The bar graph gives a quick overview of the performance of the switch. Each bar shows the highest percentage of transmitted (TX) or received (RX) traffic utilization for that port in the last five seconds.

The graph area proport ionally depicts three attributes for each por t:

Managing Switches

■ Unicast packets - The percent utilization for packet s that were not

addressed to a multicast or broa dcast address.

■ Non-Unicast packets -The percent utilization of received non-unicast

packets (bothbroadcast andmulticast). If there is abroadcast storm,only the portreceiving these packets shows high utilization, letting you quickly pinpoint the problem.

■ Errors - The percent utilization for error packets received. A high

percentage may indicate possible network problems.

Place the cursor over a bar in t he graph to display the exact percentages for each attribute and the speed of that port. The above graph displays a high percentage of non-unicast packets on port 2 (a 10 Mbps port) becau se this port is running video. Port 5 is indicating some errors.

The graph only scales to 40% utilization. Network utilization above this level indicates serious performa nce problems.

The graph also shows you if a port is active, dis a bled, or not connected.

Alert Log Area - Find/Fix/Inform

The “Find/Fix/Inform” capability of a device helps you proactively manage your network by displaying netw ork traps and problem conditions in one easily accessible browser page. The device itself monitors counte rs, in ternal hardware information, and network t ra f f ic. When a problem is discovered, such as loss of link, a problem cable, or a broadcast storm, the Alert Log displays clear messages about the problem. When you double -c lick on an alert in the Alert Log (or select the alert and click on the Open Event button), the Alerts page displays more information about the alert as well as some suggestions for fixing the problem.

For example, the Alert Log may display the alert “Cable Length”. The following information is available:

Description: Packet loss detected on port 4. This may be due to an overextended LAN

topology or faulty hardware . The loss was detected on this port, but the actual problem can be occurring elsewhere on this segment.

Solution:

Managing Switches

■ Verify the ne twork topo logy is within IEEE 802.3 topology standards. All

ThinLan coaxial cabling must be 185 meters or shorter. No more than 4 repeaters are allowed between any two stations in the network.

■ Insertbridges or switches between repeaters to extendnetwork topology

if needed.

■ Also, check for faulty cablin g, transceivers, and NICs.

Using the Find/Fix/Inform capability, the device can isolate a problem that occurs on one port, preventing it from affecting the entire network.

Using VLANS

Virtual LANs, or VLANs, are generally defined as broadcast domains created with software rather than being a funct ion of t he hardware. They can be viewed as a group of end nodes, possibly on different physical LAN segments, that can commu nicate 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 broad cast 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

■ Providing an easy, flexible, less costly way to modify logical groups in

changing environments

■ Preserving current investment in equipment and cabling

■ Allowing administrators to “fine tune” the network

■ Providing independence from the physical topology of the network

Managing Switches

7-11

Managing Switches

Configuration

VLANs make large networks more manageable. You can group users according to some shared characteristic, such as a common business function or a common protocol. A single switch may have several independent VLANs within it.

Note: VLANs must be created with the device console.

Configuration - Device Features

The Device Features page (only found on sw itches) lets you set some or all of these features:

■ Automatic Broadcast Control (ABC)

■ Multicast Filtering (IGMP)

■ Spanning Tree

Automatic Broadcast Control (ABC)

Automatic Broadcast Control (ABC) is a feature that controls broadcasts through IP/IPX Broadcast Reduction. IP /I PX Broadcast Reductio n reduces the number of broadcas ts propagated through the network.

Using ABC, the switch acts as a proxy server, replying to Address Resolution Protocol (ARP) requests, Nearest Server Query (NSQ) requests, and GetLocalTarget requests on behalf of the destination node. An ARP cache (learned address table) is created for each subnet allowing the swit ch to proxy reply with the resolved MA C address instead of forwarding the requests out all ports. This limits the broadcasts within the switching domain. The Service Advertising Prot ocol (SAP) table performs the same function in an IPX network. By using these tables, the switch can resolve

Managing Switches

addresses for any node in the network that it already knows about.

Routing Information Protocol. The switch also intercepts Routing Information Protocol (RIP) and SAP broadcasts and forwards these only to ports where routers and servers have been detected. This also reduces the number of broadcasts on t he network.

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 switch. When th e s e rver 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.

7-12

Managing Switches

Configuration

Enabling Broadcast Control for IP

The IP protocol uses Address Resolution Protoc ol (ARP) packets to find the MAC address of a node that corresponds to the network layer address. When Broadcast Control is enabled, 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 source and destinat ion MAC addresses and layer 3 addresses in its ARP cache. This information 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 unicast packet 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 periodically (every 30 seconds) to distribute routing information. By enabling Automatic IP RIP Control, the switch will only forw a rd R I P packet s out the ports on which RIP packets have been received. Since routers are the only devices that generate RIP packets, this ensu res that RIP packets are only sent out ports with routers attached to t hem. When this featu re is not enabled, IP RIP packets are forwarded to all ports.

Enabling Broadcast Control for IPX

The IPX protocol broadcasts all of its kno wn routes and services every minute by using IPX, RIP and Service Adv e rtising Protocol (SAP) packets. When servers are booted u p, they advertise their services using SAP. These frames must be forwarded by routers, which maintain a database of this information, allowing clients on the netw ork 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 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 ena bled, the switch will modify replies from the DHCP server so that the Default Gateway IP address

of client becomes the client’s own IP address. This is useful in a multinetted

7-13

Configuration

environment (where more than one I P network is configured in a single broadcast domain).

See Routing Information Protocol.

Internet Group Management Protocol (IGMP)

Multimedia and email applic ations need the ability to communicate to multiple destinations efficiently. IP multicasting allows hosts to dynamically register for sending or receiving multicast traffic.

The Internet Group Management Prot ocol is a method for automatically controlling multicast traffic through the ne twork. Using multicasting, applications can send one copy of a packet addressed to a g roup of computers that wish to receive it. This method is more efficient than sending a separate copy to each node. Other advantages of multicasting includ e:

■ information delivered in a timely, synchronized manner because all desti-

nation nodes receive the sam e pa c ke t

■ 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 receive 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

Managing Switches

which hosts are in which multicast groups, then allowing IP multicast traffic to be sent only to ports with valid host gro up members.

When a switch receives an IGMP packet, it updates the internal IP multicast forwarding table with the IGMP me mbership read from that packet. The switch then sends the packet to the ports with members of the destination multicast group.

Special multicast routers/queriers com municate b y 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 gr oup. Each host responds to the query message with a repor t message that tell s 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.

7-14

Managing Switches

Configuration

Note: Using the console you can designate specific ports to always or never forward multicast packets.

Forward with High Priority

When “Forward with High Priority” is checked, any IGMP packets received by the switch will be forwar ded 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 one active path between them at any time. The Spanning Tree Protocol uses the most efficien t path be t w een 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 t he original network configuration.

HP Admin gives you two check boxes in th e Make Device Symbols Execut- able at OpenView Startup section that allow you to change the state of the device symbols the next time OpenView is started. If the check box for Hubs/ Bridges/Switches is enabled (box is darker), the next time that OpenView is started the associated device symbols will be executable. If the check box is not enabled, the next time that OpenView is started the state of the symbols will not have changed. If the symbols were in the executable state when you exited OpenView , theywill remain inthe executable state.If the symbols were in the explodable state when you exited OpenView, they will remain in the explodable state.

Note: When an HP Admin check box is disabled, no change in the existing device symb ol st ate occurs when Op e nView is restarted.

Note: If you enable a Hub/Bridge/Switch check box while OpenView is running, the change in symbol state to executable will not occur until OpenView is restarted. OpenView checks these parameters at startup.

A Closeup View is an interactive, visual display of a device. You can use the Closeup View to obtain device 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 availabl e function icons depending on the device type. Icons for functions that are not available for some devices will either not be selectable (gray ed out) or will not appear. Also, menu options launched from icons that are not available for some devices eith er will not appear, or if they appear, they will not be selectable. For information on device management functions for any particular device, refer to the online help in the Closeup View.

ForHP AdvanceStack hubs, CloseupViews are available for managing allhubs on a Distributed Mana gement Chain. Closeu p Views for chaine d hubs that are without SNMP modules are accessed through the appropriate SNMP-based hub’s Closeup View. Functions that are not available for chained hubs will not be selectable.

Agent Firmware Versions

Appendix A

HP Hub & Switch Management communica t es wit h network devices using SNMP (Simple Network Manage ment Protocol).To access device features, each network device must contain a compatible version of agen t software or firmware.

Note: The latest firmware agents can be obtained from the Support section of the HP networking Web page. The URL is:

http://www .hp.com/go/network_city

Verifying Device Agent Versions

Y o u 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 the device’s Installation and Reference Guide for use of the device’s RS-232 console port.

• For HP devices, you can use an ASCI I terminal or computer with VT 100 terminal emulation.

■ Use an available network application (a network connection).

Appendix A

Appendix A

Preparing Network Device s

For HP devices, use an existing version of HP Hub & Swit ch Management or other device management utility.

Update the device’s software or firmware to the current supported version.

Note: HP Hub & Switch Management may be able to discover devices that have previous versions of device agent firmware. However, the use of some functions may be limited.

Preparing Network Devices

For HP Hub & Switch Management to communicate with devices on your network, the network devices must :

■ have SNMP agent firmware that is compatible with this version of HP Hub

& Switch Management.

■ for IP networks, have a uniq ue IP network address.

Note: Hubs and bridges shipped prior to July 1992 must be upgraded.

Appendix A

Basic hub management features are available for chained AdvanceStack 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

Onan IP network,each managed devicemust have an IP address. If you intend to run HP Hub & Switch Management on an IP netwo rk, you must configure the IP address for each device you want to manage.

IP addresses are normally configured 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.

Note: You can use HP Hub & Switch Management to change an IP address on a hub after it has been assigned, but not on a switch or a

Configuring IP Parameters

T o run HP Hub and Switch Management on an IP network, you mustconfigure the management station and all managed devices for IP.

A-3

Appendix A

Configuring IP Parameters

The network management station is configured for IP using the TCP/IP stack utilities. To configure a device for IP, you typically connect to the device’s console port and use the console port interface. (Refer to the device’s installation manual for more information.)

Before you configure the network management statio n and manageable devices for IP , make a list of all the devices 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 desc ribed 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 decimal number between 1 and 254. Every IP address on a network must be unique.

The default value, 0. 0.0.0, disa bles IP communications. Use the default va lue only if you are not going to manage the device with HP Hub & Switch Management and you want to d isable IP communications 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 generat ed and depends on the class of IP addre ss th at you entered. See your network administ rator 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 of the nearest router in your network. The default is 0.0.0.0.

Backup Default Router. The IP address of the router to 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 discarded. The default value is 32. Increase this value if the hub, bridge, or switch is managed from a network management station that is more than 32 routers away. The maximum allowable v a lue i s 255.

name “public” on the device to allow the device to be discovered and managed by HP Hub and Switch Management. Typically, the community name on HP hubs and bridges will automatically default to “public”.

T o configure a device for IP networks, use the device ’s console port interface. Refer to the device’s Installation and Reference Guide for use of the device’s RS-232 console port.

Note: For HP hubs, HP Hub & Switch Management can be used to change IP addresses after 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 configuration from a server on the network. A device’s IP configu ra tion must be configured in a file on the Bootp server. When the device is powe red 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 m an age me nt application (such as HP Hub & Switch Management).

■ For more information on IP configurat ion using Bootp, refer to your

device’s Installation and Reference Guide.
