Introduction

This chapter introduce s the Agil ent 498 6B Etherne t LanPro be (shown i n Figu re 11 on page 2), including its installation and configuration options.

You can use your LanProbe with NetMetrix/UX (for HP-UX and Solaris) The term “NetMetrix” is used in this manual to refer to Agilen t NetMetrix/UX.

The following sections are included in this chapter:

“Installation and Configuration Overview” on page 4

“LanProbe Overview” on page 5

The Agilent 4986B Ethernet LanProbe is a Motorola 68040-based, SNMPmanaged segment monitor fo r distrib uted Ethernet net works. Its netwo rk interface (port) consists of a single RJ-45 connector.

Figure 1-1: LanProbe

Introduction

The Ethernet LanProbe has 16 MB of memory (optionally 32 MB), and uses FLASH EPROM. Future upgrades to La nProbe’s firmware are easily do wnloaded over the LAN to multiple probes simultaneously. You can also download firmware using LanProbe’s serial port.

LanProbe maintains a variety of statisti cal 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. Traffic and error levels are also monitored per node for each station on the segment.

Private MIB extensions give LanProbe additional capabilities beyond RMON. Multiple SNMP trap addresses, or groups of addresses, can be defined for event notification. The probe maps MAC addresses to IP addresses for node identification, and provides duplicate IP address detection. A real time utilization variable has been added, which provides the ability to alarm on instantaneous peaks of network load . An additional Out-of -Ban d connection to the pr obe ca n be established using Serial Link Internet Protocol (SLIP), either directly, using a modem, or by using a data switch.

You can configure the LanProbe to perform Echo Test Monitoring (tests to verify communications) of network nodes from your network management station. LanProbe allows the netw or k manag er t o select one or several no des t o pe rf orm a one-time test or specify an interval for periodic testing. You can view the results of the Echo Test Monitoring from your NetMetrix management console. This can be very useful for monitoring critical nodes to verify connectivity. This test can also be performed from several points on the network (using several LanProbes) to verify connectiv ity from each point . When a node becomes unr eachable an aler t can be sent from LanProbe to your management station. To provide testing of a large range of nodes, Echo Test Monitoring supports ICMP, IEEE 802.2, and IEEE 802.3 for Novell IPX. This extension is supported by the NetMetrix software.

Introduction

Installation and Configuration Overview

To quickly install and configure your LanProbe, it is important for you to understand the available configuration and installation options. Configuration consists of setting the LanProbe 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:

RMON Conformance

The LanProbe implements groups 1 through 9 of RFC 1757 and groups 11 through 20 of RFC 2021. Refer to RFC 1757 for more informati on on the Remo te Network Monitoring Manage ment Inf ormati on Base Pr otocol I dentif iers (RMON1 MIB), to RFC 2021 for information on the RMON-2 MIB, and to RFC 2074 for information on Protocol Identifiers. LanProbe also supports MIB-II.

Introduction

LanProbe Overview

LanProbe also contains the Agilent Private MIB which 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.

You can refer to Table B-8 on page 104 for specific information on your probe’s protocol directory.

Management Stations

Management stations gather network data collected by Agilent LanProbes. They present this information in easy-to-use and easy-to-understand text and graphic formats. You can use a management station to communicate with your LanProbe after it has been installed and configured.

The LanProbe communicates with the NetMetrix software running on your management station. NetMetrix management applications allow you to review and reconfigure LanProbe parameters (such as IP address, trap destinations, filters, and packet captures), to manage the information collected by LanProbe (including statistics, historical studies, alarms, packet size distribution, and captured packet traces), and to monitor local or remote networks (by gathering network statistics from Agilent LanProbe agents as network monitors).

Refer to your NetMetrix docu mentation fo r more information.

Access Security

The LanProbe configuration menu allows network administrators to disable standard RMON functions which c ould be consi dered a se curity risk . The securit y menu allows network administrators to disable the RMON-1 packet capture capabilities of LanProbe to prevent network users from viewing network traffic. TFTP firmware downloads can be disabled to prevent users from downloading earlier versions of the LanProbe firmware which did not support these new security features. For more information, refer to “Modify/View Security Values” on page 20.

LanProbe Overview

Introduction

The LanProbe private MIB uses a four-level access control scheme. An access level is assigned for each communi ty stri ng to be used with Lan Probe. The acc ess level 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 shows specific access privileges by level.

This chapter describes how to install the Agilent 4986B Ethernet LanProbe Installing the Agilent LanProbe consists of the following tasks:

“Selecting a Location” on page 31

“Installing the Probe” on page 32

“Connecting the Probe” on page 37

“Starting the Probe” on page 47

“Verifying the Installation” on page 48

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 LanProbe where it will be the most useful. The LanProbe can only monit or tr affic that is present on the LAN where it i s attached. Because interconne ct device s (bridges , for ex ample) fil ter tra ffi c, a LanP robe may need to be attached on each si de of an int erconne ct devi ce fo r complet e colle ction of network statistics. In this respect, the placement of LanProbe affects the statistics collected.

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

NOTE

The Fault and Activity LEDs on the front of LanProbe will light if any of the individual port LEDs on the rear panel l igh t. To determine which port has activity or a fault, you are requ ired to lo ok at the por t LEDs on the ba ck panel. Thi s should be considered when selecting a location or LanProbe’s orientation in a rack.

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 space in a 19 inch rack or cabinet.

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

Access to one or more Ethernet connection taps.

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 address for the probe can be found on the rear labe l. It is a good id ea to make a note of this address

prior

to installing your LanProbe because some installation methods make it difficult to see the rear label without removing the probe.

Connecting the Probe

Installation

Connecting the Probe

LanProbe communicates with Agilent NetMetrix either through the In-Band network connection or by using an Out-of-Band serial connection. You can establish both In-Band and Out-of-Band connections to give you the option of communicating with the probe either over the network or over the serial link, respectively.

The In-Band connection adds a slight amount of traffic to the network, but is faster than the Out-of-Band connection. The disadvantage of using only the In-Band connection is th at certain networ k or component fai lures can resul t in loss of communication with LanProbe.

The Out-of-Band serial connection can be used as the primary means of communication or as a ba ckup link in case of a network failure. The dis advantage of using only the Out-of-Band connection is that it is a slower means of communications.

CAUTION

Connecting to the Network (In-Band)

You can connect LanProbe to the network by connecting the 10Base-T (RJ-45) port. Figure 3-13 on page 38 shows the rear panel of LanProbe.

Do not touch the probe connector pins or the cable connector pins. Static discharge may damage equipment.

Configure the Management Station and LanProbe

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.

Connecting the Probe

Installation

The LanProbe 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 config ure LanProbe, make the network connection (r efer to “Connecting to the Network (In-Band)” on page 37) and then refer to your NetMetrix documentation to configure the following LanProbe 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 LanProbe as described in Chapter 2 “Local Terminal Configuration”, attach the terminal and configure the following LanProbe 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 LanProbe’s menu or over the network from a NetMetrix management station (refer to your NetMetrix documentation for details).

Installation

Connecting the Probe

Verify that the Modem Init String is properly ini tialized 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 applicable): 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 LanProbe.

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

Connecting the Probe

Installation

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 LanProbe.

T o mak e a da ta switch co nnec tion to LanP robe, c onnect a NetMet rix manage ment station to LanProbe’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 317 on page 46 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 and Agilent Power Module (0950-2546) 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 and Agilent Power Module to LanProbe. The probe doe s not have a power switc h, but is powered on when power i s a tt ac hed. When powered on or re set , La nPr obe 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 autodiscove ry echo interval. Refer to Cha pter 5 “LanPro be Operation” for more information on resetting the probe.

Installation

Verifying the Installation

You can verify the LanProbe installation by looking at the status LEDs on the front of the pro be. Af t er the LanProbe restar ts (boots), it runs a power-on self-test (POST) and then starts normal operations.

The Fault LED is briefly turned on (about three seconds) during the POST. After LanProbe 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 LanProbe 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

Link On when attached to a 10Base-T network

Collision Off (or flashing if connected to a network with collisions)

You can use NetMetrix to verify that LanProbe can be reached (refer to your NetMetrix documentation).

Verifying the Installation

Installation

Troubleshooting the Installation

If the Activity LED is off, verify that LanProbe is properly connected to the network and that there is traffic on the network.

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

If the Fault LED is on, the probe failed the self-test. Repeat the installation procedures and verification of installation.

If you are still having d iff iculty, call your local Agilent service represent ative.

Bootp Server Configuration

This chapter describes how to use the Bootp server method to configure the Agilent 4986B Ethernet LanProbe so that it can communicate over the network. This chapter assumes that you have already installed LanProbe, but have not attached the power cord and Agilent Power Module (0950-2546). If you plan to use the loca l terminal m ethod of configuration, skip this cha pter and refer to Chapter 2 “Local Terminal Configuration”.

The following sections are covered in this chapter:

“Probe Configuration Using a Bootp Server” on page 53

“Bootp Server Setup on a PC” on page 59

“Configuring the Bootptab File” on page 65

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 LanProbe’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 4-2 on page 54 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 LanProbe parameters. Refer to “Configuring the Bootptab File” on page 65 for more information.

LanProbe’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.

T o all ow LanProbe to use a Bootp ser ver tha t is not on th e same subnet , the router involved must support Boot p Relay (the tra nsfer of a Bootp req uest). For exampl e, if you have multiple LanProbes that you want to configure from a single Bootp server, be sure that the routers in the path between your Bootp server and the LanProbes support Bootp Relay. Otherwise, you will need to operate the Bootp server on the same subnet as your LanProbes. You can configure multiple LanProbes on one subnet and then place them on their respective segments.

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 57.

6. Connect the power cord and Agilent Power Module (0950-2546) to

LanProbe and to a power source (either 100-120/VAC or 220-240/VAC). LanProbe 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 requestswhen 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 65, 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 LanProbe has been assigned the correct IP address and shows up on the management station map as a network analyzer. The discovery process that places LanProbe in the management station map can take several minutes to complete.

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

As a TSR (terminate-and-stay-resident) program by entering the following:

bootpd -a IP address

Bootp Server Configuration

Bootp Server Setup on a PC

Where:

-a IP address is required and specifies the IP address of the PC where you are running bootpd.

-s specifies that you are running bootpd as a standalone executable (not as a TSR). You may want to use the -s option if you do not need t he Bootp daemon to continually service boo tp reques ts. This is pre ferable , since the Boot pd TSR may consume a large amount of memory (depending on the size of your bootptab file).

Upon startup, Bootpd reads the bootptab file and then listens for bootp request packets from the network. Bootpd re-reads the bootptab file when it receives a bootp request packe t and detec ts tha t the fi le has been u pdated. If hosts a re added, deleted, or modified, their entries in Bootpd’s internal database are also updated when the bootptab file is re-read. All Bootp status messages are logged to the BOOTPD.LOG file.

You can now attach the power cord and Agilent Power Module (0950-2546) to LanProbe and to a power source (either 100-120/VAC or 220-240/VAC). LanProbe does not have a power switch but becomes operational when power is attached. When powered on and when its IP address is 0.0.0.0 (the default), LanProbe automatically broadcasts Bootp request s that trigge r the Bootp ser ver to provide its configuration parameters.

LanProbe Operation

Restarting the Probe

Cycling Power

A power outage or cycling power to LanProbe causes a warm start. LanProbe does not have a power switch; therefore, cycling the power consists of disconnecting and reconnecting the power cord.

Selecting the Warm Start Menu Item

Use the following procedure to warm start the probe using LanProbe’s Main Menu:

1. Connect a local terminal (or a PC emulating a terminal) to LanProbe. Refer to Chapter 2 “Local Terminal Configuration” for informat io n on connecting a local terminal.

2. Press the CONFIG button once (on the back of the probe) to place La nProbe into the configuration mode. Use a narrow, pointed object (like a pen) to press the recessed CONFIG button. LanProbe then displays its Main Menu on the terminal. Figure 5-18 shows LanProbe’s Main Menu.
