Introduction

This chapter introduces the Agilent J3919A and J3972A OC-3 ATMProbes, shown in Figure 1-1 on page 3, including its installation and configuration options. The OC-3 ATMProbe supports the OC-3c, STS3C and STM-1 standards.

You can use your ATMProbe with the NetMetrix/UX software, supported by HP-UX and Solaris. The term “NetMetrix” is used in this manual to refer to Agilent NetMetrix/UX.

The following sections are included in this chapter:

“Installation and Configuration Overview” on page 4

“Probe Overview” on page 5

The Agilent J3919A and J3972A OC-3 ATMProbes are MIPS-based, SNMP-managed ATM interface monitor for OC-3 Asynchronous Transfer Mode (ATM) networks. The ATMProbe is an intelligent device that must be physically located at the site where the ATM circuits reside.

The base hardware configuration supports an OC-3 ATM interface, a 10Base-T/ 100Base-TX telemetry interface, and a SLIP connection. The OC-3 ATMProbe can also be ordered with an optional Token-Ring telemetry interface. The OC-3 ATM interface supports monitoring both directions of a full-duplex circuit simultaneously. Probe data is retrieve d using SNMP v ia a LAN or SLIP connection.

The 10Base-T/100Base-TX telemetry interface uses a RJ-45 connector. The Ethernet telemetry interface uses an AUI connector. The telemetry port retrieves data associated with the other interfaces on probe, but does not maintain RMON or other network statistics for its own network. The optional Token-Ring telemetry interface uses either an RJ-45 or DB-9 connector. The OC-3 ATM interface uses either multimode or single-mode transceivers with two Fiber SC connectors.

Introduction

The OC-3 ATMProbe also has a 6-pin mini-DIN connector (Bypass Power) that allows ATMProbe to be connected to an external optical bypass. The optical bypass maintains the net work link even if the OC-3 ATMProbe has an interrup tion in power; it functions only when using fiber SC connectors.

Figure 1-1: The Probe

The OC-3 ATMProbe has 32 MB of memory (optionally 64 or 128 MB), and use s FLASH EPROM. Future upgrades to the probe’s firmware are easi ly downloaded over the LAN to multiple probes simultaneously. You can also download firmware using the probe’s serial port.

The AT MProbe maintains a variety of statistical measurements on network performance, continuously keeping track of traffic levels, errors, and other important trends. Alarm thresholds can be set on any of these parameters, immediately alerting the network manager or initiating a packet trace to capture the details of the event for later analysis. AAL-5 traffic and error levels are monitored for the ATM connection. This information is available on a per-PCV basis or as an aggregate of all active SVCs. Information related to SVCs is aggregated into a single set of statistics representing all SVCs.

In addition to usi ng SNMP and selected RMON MIB group s, t he ATMProbe uses Agilent private MIB extensions to give additional capabilities. Multiple SNMP trap addresses, or groups of addresses, can be defined for event notification. A real-time utilization variable has been added, which provides the ability to alarm on instantaneous pe aks of netwo rk lo ad. An addi tiona l Out- of-Band co nnection to the probe can be established using Serial Link Internet Protocol (SLIP), either directly, using a modem, or by using a data switch.

Introduction

Installation and Configuration Overview

To quickly install and configure your probe, it is important for you to understand the available configuration and installation options. Configuration consists of setting the probe parameters (IP address, for example). Installation consists of physically installing the probe and connecting it to the network.

You will reference different chapters of this Installation/User’s Guide depending on which of the following installation and configuration options you select:

“Local Terminal Configuration and Installation” below

“Installation and Bootp Server Configuration” below

Local Terminal Configuration and Installation

This method of installation and configuration requires that you configure the probe first and then install the probe. These procedures are detailed in Chapter 2 “Local Terminal Configuration” and Chapter 3 “Installation”.

Installation and Bootp Server Configuration

This method of installation and configuration requires that you install the probe first and then configure the probe. These procedures are detailed in Chapter 3 “Installation” and Chapter 4 “Bootp Server Configuration”.

Introduction

Probe Overview

This section provides some general information on the Agilent J3919A and J3972A OC-3 ATMProbes.

CAUTION

Since the OC-3 ATMProbe repeats the received signal, a loss of power to the probe results in an interruption of the network signal on the monitored fiber link. To eliminate this possibility, you must install the optio nal Optical Bypass (Option

125).

The ATMProbe implements groups 3, 7, 8, and 9 of RFC 1757, the Remote Network Monitoring Management Information Base (RMON-1 MIB). Refer to the RFC for more information.

The ATMProbe also implements the Agilent Private MIB, which contains all ATM statistics and allows for configuration and administration of the probe. It provides enhanced authentication features, specification of trap destinations, remote download of new firmware revisions, serial line control, and other features. The Agilent Private MIB is available electronically with NetMetrix.

Introduction

Probe Overview

Management Stations

Management stations gather network data collected by Agilent probes. They present this information in easy-to-use and easy-to-understand text and graphic formats. You can use a management station to communicat e with your probe af ter it has been installed and configured.

The probe communicates with the NetMetrix software running on your management station. NetMetrix management applications allow you to review and reconfigure the probe parameters (such as IP address, tra p destinations, fi lters, and packet capture s), to manage the i nfor mation colle ct ed by the probe ( incl uding statistics, historical studies, alarms, and cap tured packet traces), and to monitor local or remote networks (by gathering network statistics from Agilent Probe agents as network monitors).

Refer to your NetMetrix docu mentation fo r more information.

Access Security

The probe’ s con figuration menu a llows network administrat ors to disable standard RMON functions which could be considered a security risk. The security menu allows network administrators to disable the RMON-1 packet capture capabilities of the prob e to prevent network use rs from viewi ng network t raffic. TFTP firmware downloads can be disabled to prevent users from downloading earlier versions of the probe f ir mwa re which did not support these new se cur it y features. For more information, refer to “Modify/View Security Values” on page 24.

The probe’s private MIB uses a four-level acces s control scheme. An acce ss l eve l is assigned for each community st ring to be used with the probe. The access lev el is an integer value between one and four, with increasing degrees of authorization granted for higher authorization numbers. Each higher level is granted the rights of all lower levels in addition to the specific privileges of that level. Table 1-1 on page 9 shows specific access privileges by level.

Local Terminal Configuration

Using a Local Terminal

NOTE

If the optional Token-Ring telemetry interface is not installed, the probe will not allow you to change the Fast Ethernet interface’s port type from telemetry.

If the Token-Ring telemetry interface is installed, you can configure either the Fast Ethernet int erfac e or the Token-Ring interface as the telem etr y inter face . The Fast Ethernet interface comes from the factory configured as Telemetry and the Token-Ring interface comes configured as Monitor/Transmit and is disabled. “Disabled” in this case means that the interface does not function at all, not as a Telemetry port nor as a Monitor/Transmit port. If you configure the Token-Ring interface as Telemetry, the Fast Ethernet interface automatically becomes configured as Monitor/Transmit and is disabled.

Port Type The Fast Ethernet interface can onl y be used as a Telemetry

port. The telemetry port does not maintain network statistics for the Fast Ethernet interface. The telemetry interface only allows the retrieval of ATM network statistics. Port 1 is the Fast Ethernet interface and it is the telemetry port by default. If the Token-Ring interface is also installed, you can select either the Fast Ethernet or the Token-Ring interface (but not both) as the tele metry port. Refe r to “Token-Ring Telemetry Interface Configuration” on page 29 for information on configuring the Token-Ring interface. The probe must be configured with exactly one telemetry port.

The Telemetry port only receives packets destined to the telemetry port’s IP address, can transmit packets onto the network, and is used for SNMP co mmunications to t he probe.

Installation

This chapter describes how to install Agilent J3919A or J3972A OC-3 ATMProbe. Installing an Agilent probe consists of the following tasks:

“Selecting a Location” on page 43

“Installing the Probe” on page 44

“Connecting the Probe” on page 49

“Starting the Probe” on page 68

“Verifying the Installation” on page 69

If you plan to configure the probe from a local ter mina l and have not yet done so, go to Chapter 2 “Local Terminal Configuration”, and perform the configuration now.

Selecting a Location

Installation

Selecting a Location

Select a location for your probe where it will be the most useful. The probe must be connected to a LAN to retrieve data. The data that can be retrieved was previously monitored from traffic present on the ATM where it is attached.

Consider the following installation requirements when selecting a location for your probe:

A flat surface that i s lar ge enough to suppo rt the probe (requires clear ance at rear and sides for cooling and rear panel access), adequate wall space, or double high space in a 19 inch rack or cabinet.

A grounded power outlet (either 100-120/VAC or 220-240/VAC).

Access to a Fast Ethe rnet connect ion t ap or to a Token-Ring network MsAU connection (if the Token-Ring Telemetry option is installed).

NOTE

Access to the ATM connection to monitor.

Access to an RS-232C connection (required only for Out-of-Band communication).

Access to a phone line and a modem within 50 feet (required only for Outof-Band communication using a modem connection).

The MAC addresses for the probe can be found on the r ear pane l. It is a good id ea to make a note of the interface and its address

prior

to installing your probe because some installation methods make it difficult to see th e rear panel without removing the probe.

Installation

Installing the Probe

This section describes how to install your probe. First decide which installation method you are going to use and then install the probe using one of the following methods:

“Table Installation” on page 45

“Rack or Cabinet Installation” on page 45

“Wall Installation” on page 47

CAUTION

not

attach the power cord to the probe until the probe is completely installed. If the power cord is already attached to the probe, remove it now (you will not lose any configuration parameters). The probe does not have a power switch but becomes operational when the power is attached.

Table Installation

Use the following procedure to install the probe on a table:

1. Attach the self-adhesi ve ru bber fee t t o the bot t om of the probe as marked in each corner.

2. Place the probe on a flat surface (refer to the requirements as listed in “Selecting a Location” on page 43).

Rack or Cabinet Installation

You can install the probe in a rack or cabinet with either the front or rear panel facing out. You may want the rear panel facing out so that you can see the status LEDs for each port. (The front panel Fault and Activity LEDs indicate when the 10Base-T/100Base-TX telemetry interface LEDs are lit.)

Make sure you have screws that fit your rack (or cabinet) before installing the probe as noted in Step 3 below.

Use the following procedure to install the probe in a rack or cabinet:

1. Attach the installation brackets to the probe with the 10-mm #M4 screws

(included), using a POZIDRIV #2 or cross-head screwdriver as shown in Figure 3-1 on page 46.

2. Position the probe in the rack (or cabinet) and slide it up or down until the rack holes line up with the holes in the brackets.

3. Attach the probe to the rack with the 5/8-in. #12-24 scre ws (included). Some cabinets require 5/8-in. #10-32 screws (available as Agilent part number 2680-0302) instead of the 5/8-in. #12-24 screws.

Connecting the Probe

Installation

Connecting the Probe

The probe communicates with Agilent NetMetrix through Out-of-Band connections using the 10Base-T/100Base-TX or Token-Ring (optional) telemetry interfaces or by using a serial connection. You can connect to an ATM network using the OC-3 ATM interface.

You can establish both telemetry and serial Out-of-Band connections to give you the option of communicati ng with the pro be either over the telemetry network or over the serial link, respectively. The telemetry connection has the advantage of being faster than the serial connection. The disadvantage of using only the telemetry connection is that certain network or component failures can result in a loss of communications with the probe.

The Out-of-Band serial connection can be used as the primary means of communication or as a backup l ink in ca se of a f ailur e on your t elemet ry network. The disadvantage of usi ng only the ser ial connec tion is tha t it is a slowe r means of communications.

You can connect an Optical Bypass switch and cable (optional) to the probe’s Bypass Power connector as specified in the bypass switch instructions. The bypass switch allows uninterrupted network performance if the probe losses power. The probe does not require the bypass switch to function properly.

Refer to one of the following sections in this chapter for specific information on connecting the probe:

disruption of all

Connecting the Probe

Installation

Do not attach cables to both the Token-Ring DB-9 and RJ-45 connectors simultaneously. This causes the probe to malfunction, and can disrupt your network. You must use only one network connector at a time for correct probe operation.

CAUTION

The Token-Ring interface is not compatible with Token-Ring expansion modules (Local Ringhub from Madge and other vendors, for example) which require power from the Token-Ring interface. The Token-Ring interface must be connected directly to the MsAU.

T oken-Ri ng networks typical ly use Type 3 (Unshielded Twisted Pair (UTP)) cable or Type 1 (Shielded Twisted Pair (STP)) cable. Networks using UTP cable typically use the RJ-45 type connectors and networks using STP cable typically use Token-Ring Data Connectors or DB-9 type connectors.

If your network uses RJ-45 connectors, you will need the standard cable with RJ-45 connectors on both ends to connect the probe to the ring. Connect one end of this cable t o any op en port of a Medi a Stat ion Access Unit ( MsAU) and connect the other end to the RJ-45 connector on the probe. Figure 3-6 shows the TokenRing interface connected to a Type 3 MsAU.

Figure 3-6: Connecting the Probe using RJ-45 Connectors

Installation

Connecting the Probe

NOTE

Do not connect the probe to either the ring-in (RI) or ring-out (RO) connection port.

The T oken-Ri ng interfa ce can also be connect ed to a Type 3 MsAU using a Media Filter. The Media Filter is used to connect from STP (DB-9) to UTP (RJ-45). Figure 3-7 shows the Token-Ring interface connected to a MsAU using a Media Filter.

Figure 3-7: Connecting the Probe using a Media Filter

If your network uses the Token-Ring Data Connectors, you need a Type 1 cable with a Token-Ring Data Connector on on e end and a DB-9 connector on the other end to connect the probe t o the ring. Connect the Token-Ring Data Connector plug to any open port (excludin g the RI or RO por ts) of a MsAU and con nect th e DB-9 connector to the probe’s DB-9 connector .

Figure 3-9: Close-up of the OC-3 Interfaces

NOTE

Figure 3-10: OC-3 System

Reference Figure 3-10 and use the following procedure to connect the OC-3 ATMProbe to an OC-3 ATM network with a momentary interruption to service:

If the output of the probe’s OC-3 ATM Interface is transmitted into a multi-mode fiber without using a 10d b attenuat or , it ca n saturat e the receive r’s photodiode and cause bit errors, but no damage can occur. You can order a set of 2 10dB attenuators from Agilent (Agilent J2928A).

Connecting the Probe

Installation

1. Disconnect the cable between the ATM/OC-3 switch and router.

2. Connect the OC-3 ATMProbe’s Port 1 to the ATM/OC-3 Switch port that was just disconnected i n Step 1. Figure 3-1 1 sh ows how to connect th e probe to an OC-3 ATM network.

3. Connect the OC-3 ATMProbe’s Port 2 to the router port that was just disconnected in Step 1.

In this connection scheme, the probe monitors network traffic as if the signal between the switch and Router is sent straight-through the probe.

NOTE

Port 1 of the probe’s OC-3 ATM Interface is for connecting to an ATM/OC-3 switch and Port 2 is for connecting to a router. It might be necessary to swap cables.

Agilent OC-3 ATMProbe

Figure 3-11: Connecting the Probe to an OC-3 ATM Network

Installation

Connecting the Probe

Depending on what type of testing you want to do with the probe’s OC-3 ATM Interface, you may need some of the following equipment:

You may need to put an Attenuator on the output of the probe’s OC-3 ATM

Interface or the output of the laser source when you are connecting to a network. You can order a set of 2 10dB attenuators (Agilent J2928A).

Optical Splitters are used when you want to passively monitor network

traffic. You can order a multi-mode SC-to-SC Optica l Power Splitter (Agilent J2929A).

Bypass Mode

The probe has a 6-pin mini-DIN connector that allows the probe to be connected to an external optical bypass. The optical bypass is optional and only functional when using the fiber SC connectors. The probe’s optical bypass is used to maintain the network link even if the probe experiences a power interruption.

Optical Bypass Switches (optional equipment) are required to create a fault tolerant application with fiber networks.

For the Fiber connections, the Bypass Mode is accomplished by using the probe’s optical bypass connector. This 6-pin mini-DIN connector is located on the back of the probe, refer to Figure 3-3 on page 51. The optical bypass connector provides power to an external, optical-bypass switch that bypasses the probe when it experiences a power inter ruption. The res ult is no int erruption to the network. The external, optical-bypass switch must be ordered separately. Refer to the instructions that come with the optical-bypass switch to connect it to the probe.

Connecting to the Serial Port (Out-of-Band)

Out-of-Band communications with the probe are conducted through the serial port, not over the network. This mode of communications is optional.

Connecting the Probe

Installation

The following methods are available for Out-of-Band connections:

Configure the Management Station and the Probe

Refer to your NetMetrix documentation for information on configuring the management station for use with a modem. Verify that the packet retransmission timeout is set appropriately. For example, a 1500-byte SNMP packet requires about one second to transmit over a 9600 baud connection, with another one second for the reply. A packet retransmission timeout of three to five seconds is appropria te for this example.

Installation

Connecting the Probe

The probe can be configured for Serial Line Internet Protocol (SLIP) link communications either by using a local terminal through the serial port or by using a NetMetrix management station over the network.

If you use the network to configure the probe, make the network connection (r efer to “Connecting to the Network (Out- of-Band)” on page 50) and then refer to your NetMetrix documentation to configure the following probe parameters:

Serial Port IP Address

Serial Port Subnet Mask

Serial Port Speed

Hardware Flow Control (if unsure, consult your modem’s documentation)

Modem Init St ring

If you use an ASCII terminal to configure the probe as described in Chapter 2 “Local Terminal Configuration”, attach the terminal and configure the following probe parameters:

Serial Port IP Address

Serial Port Subnet Mask

Serial Port Speed

Hardware Flow Control (if unsure, ask your local network administrator)

Modem Init St ring

The Serial Port IP Address must be on the same IP subnet as the management station’s serial IP address.

Normally, each company has one subnet mask that is used for all machines on their network. Enter this subnet mask value into the Serial Port Subnet Mask field. The Serial Subnet Mask used for the probe should match the subnet mask used for the SLIP port on the management station.

Set the Serial Port Speed to a value that is less than or equal to the maximum speed at which your modem can operate.

Set the Hardware Flow Control to Off (On is the default), unless you are using high speed modems (14.4K baud or faster) with advanced features, such as error correction and data compression. If the Hardware Flow Control is set to On, you can set it to Off by using the probe’s menu or over the network from a NetMetrix management station (refer to your NetMetrix documentation for details).

Connecting the Probe

Installation

Verify that the Modem Init String is properly initialized for the attached modem by referencing the modem’s documentation. The probe’s default modem initialization string is configured to w ork with low-speed and medium-speed Hayes compatible modems. The following modem setting s ar e r ec ommended for low-speed to medium-speed modem connections:

Modem Flow Control: Off Data Compression (if appl icable): Off Error Correction (if applicable): Off

Not all Hayes commands are the same for all Hayes-compatible modems. Refer to your modem’s documentation to determine the commands required for each of the above settings and append these commands to the end of the default Modem Init String.

NOTE

Your modem’s documentation discusses the features that are relevant to your modem. If your modem does not support a feature (data compression, for example), you do not need to turn it off in the Modem Init String.

Some modems require you to set register values explicitly, rather than sending Hayes style commands. In this case, follow your modem’s documentation to set these registers.

If you are using a high-speed modem, you probably need to modify the default modem initialization string. The following modem settings are recommended for high-speed modem connections:

Modem Flow Control: Hardware Flow Control (RTS/CTS signaling) Carrier Dete ct: Always On Data Compression: Enabled Error Correction: Enabled

After appending the appropriate commands to the modem initialization string, warm start your probe.

Refer to your NetMetrix docu mentation fo r information o n how to establ ish communications with the probe over the SLIP link.

Installation

Connecting the Probe

Data Switch Connection

Use the data switch connection to provide the flexibility of using more than one management station to communicate with more than one probe.

To make a data switch connection to the probe, connect a NetMetrix manag ement station to the probe’s RS-232C port through a data switch. Set the Serial Port Mode to Direct, if your probe is directly connected to the data switch, or set it to Modem, if your probe must dial through a modem to another modem that is attached to the data switch.

To allow traps to be sent from the probe to your management station, specify a Serial Trap Destination of type Switch or Modem Switch, using NetMetrix.

Refer to your data switch documentation for information on setting up your data switch. There are many variations available for this connection method. Figure 314 on page 67 shows a possible data switch connection scheme.

NOTE

If you are using the Bootp serv er method of configur ation, do not atta ch the power cord to the probe until told to do so in Chapter 4 “Bootp Server Configuration”.

If you used the local terminal method of configuration, attach the power cord to the probe. The probe does not have a power switch, but is powered on when power is attached. When powered on or reset, the probe runs self-tests and transmits ICMP echo frames to the default gateway for the purpose of allowing the probe to be discovered by the routers (ARP cache). The probe transmits four ICMP echo request packets about 10 seconds after booting and again every autodiscovery echo interval. Refer to Chapter 5 “Probe Operation” for more information on resetting the probe.

Verifying the Installation

Installation

Verifying the Installation

You can verify the probe’s installation by looking at the status LEDs on the front or back of the probe. LEDs on the back of the probe show the status of each port and the LEDs on the front of the probe indicate the status of the 10Base-T/ 100Base-TX telemetry interface. After the probe restarts (boots), it runs a poweron self-test (POST) and then starts normal operations.

The Fault LED is briefly turned on (about three seconds) during the POST. After the probe passes the POST, the Fault LED turns off. The Activity LED flashes during network activit y . The ~ Line On or Power LED should be on to indicate that power is applied to the probe.

After the probe has passed its self-tests, look at the status LEDs to verify your installation. The status LEDs should be in the following states:

LED State

Activity Flashing, if connected to a network with traffic, or may

appear to stay on solid during periods of steady traffic.

~ Line On or Power On solid

Fault Off

You can use NetMetrix to verify that the probe can be reached (refer to your NetMetrix do cumentation) .

Installation

Verifying the Installation

Out-of-Band Troubleshooting

For the Ethernet or Token-Ring telemetry interface, if the Activity LED is off, verify that t he probe is proper ly connected to th e tel em et r y network and that there is traffic on the network. Also, verify th at you have the corr ect Physical Connect or selected from the Modify/View Interface Values menu.

If the ~ Line On or Power LED is off, verify that power is properly connected to the probe and to the correct power source.

If the Fault LED is on, the probe failed the self-test. Repeat the installation procedures and verifi cation of instal lation. If y ou have an option inst alled, you can look at each port’s Fault LED to see which port is generating the fault condition.

For the Token-Ring telemetry interface, if you are st il l ha vin g difficulty, call yo ur local Agilent se rvice re presenta tive. For the Eth ernet te lemetr y interf ace, c ontinue with the following “Ethernet Telemetry Interface” section.

There should be a cable connected to both connectors. Both Activity LEDs (from network and from equipment) should turn on when

there are cells present on the network and the Cell Sync LED should be off. If both the Cell Sync LED and the Activity LED are turned on, the ATMProbe is

sensing traffic on the network but is not able to synchronize on the cell stream. Verify the configuration of the probe’s OC-3 interface as described in See “OC-3 ATM Interface Configuration” on page 33.

If the Cell Sync LED is turned on and the activity LED is turned off, and you know that there is data on the network, try switching the connectors as they are attached to the ATMProbe. Each connector has a specific purpose. If the cables are attached to the wrong connectors, the probe will not receive data.

Bootp Server Configuration

This chapter describes how to use the Bootp server method to configure the Agilent J3919A or J3972A OC-3 ATMProbe so that it can communicate over the network. This chapter assumes th at you have al ready i nstal led the pr obe, but have not attached the power cord. If you plan to use the local terminal method of configuration, skip this chapter and refer to Chapter 2 “Local Terminal Configuration”.

The following sections are covered in this chapter:

“Probe Configuration Using a Bootp Server” on page 75

“Bootp Server Setup on an HP or Sun System” on page 77

“Bootp Server Setup on a PC” on page 81

“Configuring the Bootptab File” on page 87

Probe Configuration Using a Bootp Server

Bootp Server Configuration

Probe Configuration Using a Bootp Server

You can use a Bootstrap Protocol (Bootp*) server to load the probe’s IP configuration. This method requires that a Bootp server maintains a file containing client configuration information, maps from MAC addresses to IP addresses, and responds to requests from clients. You can configure the probe from an HP-UX, Solaris, or MS-DOS syst em acting as a Bootp server. The system that is operat ing as t he Bootp server must be connected to your n etwork. Table 4-1 on page 76 shows the minimum requirements for a Bootp server operating on HP 9000, Sun SPARC, and PC systems.

Before you can use the Bootp server, you must edit the bootptab file to configure the required probe parameters. Refer to “Configuring the Bootptab File” on page 87 for more information.

The probe’s MAC address is twelve characters long and is printed on a tag on the back of the probe. You must determine the IP Address, Default Gateway IP Address, and Subnet Mask from the network.

To allow the probe to use a Bootp server that is not on the same subne t, t he router involved must support Boot p Relay (the tra nsfer of a Bootp req uest). For exampl e, if you have multiple probes th at you want to configu re from a singl e Bootp server, be sure that the routers in the path between your Bootp server and the probes support Bootp Relay. Otherwise, you will need to operate the Bootp server on the same subnet as your pro bes. You can configure multiple probes on one subnet and then place them on their respective segments.

Bootp Server Setup on an HP or Sun System

If your Bootp server is an HP-UX or Solari s system, use the followi ng instructions to configure the probe:

1. Determin e the IP address to be used for the probe.

2. Determine the name to be used as the probe’s Domain Name Services (refer to the HP ARPA Services manual) or configure an IP address and name for the probe in your loca

3. Make sure that the Bootp ser ver can communicate with th e probe ( if they a re separated by a router, the router must support Bootp Relay).

4. From the Bootp server, edit the client configuration file and enter the following parameters to be used for the probe (do not specify any other parameters):

l /etc/hosts file.

NOTE

MAC Address

IP Address

Default Gateway IP Address (if avai lable)

Subnet Mask

The Bootp server must support the vendor specific subnet mask field and the default gateway field.

5. Start the Bootp daemon as des cribed i n “Star ting t he Bootp Server on an HP or Sun System” on page 79.

6. Connect the power cord to the probe and to a power source (either 100-120/ VAC or 220-240/VAC). The probe does not have a power switch but becomes operational when power is attached.

Bootp Server Configuration

Bootp Server Setup on an HP or Sun System

The probe automatically broadcasts Bootp requests when its IP address is

0.0.0.0 (the default). The probe broadcasts Bootp requests to signal its

need to be configured.

7. For HP-UX systems: Log in as root , then use SAM to fol low the i nstructi ons presented on the screen.

For HP-UX 9.x, choose:

Networking/Communications -> Service:Enable/Disable

For HP-UX 10.x and 11.x, choose:

Networking and Communications -> Network Services

NOTE

If the last screen presented in Step 7 displays bootp server enabled, (for either HP-UX 9.x, HP-UX 10.x, or HP-UX 11.x) then your machi ne is already set up as a bootp server.

8. Edit the /etc/bootptab file to configure the probe and add descriptive comments to the file for reference. Refer to “Configuring the Bootptab File” on page 87, the bootpd(1M) man page or the HP ARPA Services manual for more information on configuring the /etc/bootptab file.

9. Use tail -f to check the system log file to ensure that the Bootp server responded correctly to the Bootp request. The log file is /var/adm/

messages (Solaris), /usr/adm/syslog (HP-UX 9.x), or /usr/ adm/syslog/syslog.log (HP-UX 10.x and 11.x).

10. If you are using HP OpenView, you can verify that the probe has been assigned the correct IP address and shows up on the management station map as a network analyzer. The discovery process that places the probe in the management station map can take several minutes to complete.

You may be able to decrease the required time for discovery of the probe by pinging it continuously from your HP NetMetrix management station. You can also ping the probe to verify that it responds to the new IP address.
