Introduction
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:
z “Installation and Configuration Overview” on page 4
z “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 retrieved using SNMP via 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.
2
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 network link even if the OC-3 ATMProbe has an interruption
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 uses
FLASH EPROM. Future upgrades to the probe’s firmware are easily downloaded
over the LAN to multiple probes simultaneously. You can also download
firmware using the probe’s serial port.
The ATMProbe 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 using SNMP and selected RMON MIB groups, the 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 peaks of network load. An additional Out-of-Band connection to
the probe can be established using Serial Link Internet Protocol (SLIP), either
directly, using a modem, or by using a data switch.

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 communicate with your probe after
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, trap destinations, filters,
and packet captures), to manage the information collected by the probe (including
statistics, historical studies, alarms, and captured packet traces), and to monitor
local or remote networks (by gathering network statistics from Agilent Probe
agents as network monitors).
Refer to your NetMetrix documentation for more information.
Access Security
The probe’s configuration menu allows network administrators 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 probe to prevent network users from viewing network traffic. TFTP
firmware downloads can be disabled to prevent users from downloading earlier
versions of the probe firmware which did not support these new security features.
For more information, refer to “Modify/View Security Values” on page 24.
The probe’s private MIB uses a four-level access control scheme. An access level
is assigned for each community string to be used with the probe. The access 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 on
page 9 shows specific access privileges by level.

Status LEDs
Your probe has status LEDs for the base hardware configuration (the 10Base-T/
100Base-TX telemetry interface), for the OC-3 ATM interface, and for the
optional Token-Ring telemetry interface.
The following sections cover the possible status LEDs on your OC-3 ATMProbe:
z “10Base-T/100Base-TX Telemetry Interface Status LEDs” below
z “Token-Ring Telemetry Interface Status LEDs” on page 12
z “OC-3 ATM Interface Status LEDs” on page 13
10Base-T/100Base-TX Telemetry Interface Status LEDs
The status LEDs for the 10Base-T/100Base-TX telemetry interface are visible on
the front and back of the probe. Figure 1-3 on page 11 shows the LEDs on the
front of the probe and Figure 1-4 on page 12 shows the LEDs on the back of the
probe.
The ~ Line On, Activity, and Fault LEDs are on the front of the probe.
On the back of the probe, there are LEDs associated specifically with each
interface and a Power LED. The 10Base-T/100Base-TX telemetry interface has
LEDs for Activity, Link and Collision.
Refer to the following list for information on how these LEDs work:
~ Line On or Power. This green LED is turned on when the probe is receiving
power.
Activity. This green LED is turned on when data is being received from the
Ethernet telemetry network or transmitted by the probe. When flashing, the
frequency shows the amount of traffic. During periods of steady traffic, it may
appear to stay on solid.

ATM interface from the network. When flashing, the frequency shows the amount
of traffic. During periods of steady traffic, the LED may appear to stay on solid.
Cell Sync. This yellow LED is turned on when the OC-3 ATM interface detects a
loss of cell synchronization.
The following LED is on the Agilent J3972A probe only:
Fault. This yellow LED is turned on when the processor on the Agilent J3972A
probe is not running. The Fault LED can turn on during the power-on self-test, but
should be off when the probe is running.
CONFIG Button
The CONFIG button is used to configure the probe from a terminal or to restart
the probe. The CONFIG button is recessed and located on the back of the probe
near the RS-232C connector. You will need to use a narrow, pointed object (like a
pen) to press the CONFIG button.
To configure the probe using a local terminal (or PC emulating a terminal),
connect a terminal to the probe using a null modem cable and push the CONFIG
button to display the probe’s Main Menu. This operation is described in Chapter 2
“Local Terminal Configuration”.
You can restart the probe (with a warm start or cold start) using the CONFIG

parameters.
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 interface or the Token-Ring interface as the telemetry interface. 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 only 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 telemetry port. Refer 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 communications to the probe.

Selecting a Location
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:
z A flat surface that is large enough to support the probe (requires clearance at
rear and sides for cooling and rear panel access), adequate wall space, or
double high space in a 19 inch rack or cabinet.
z A grounded power outlet (either 100-120/VAC or 220-240/VAC).
z Access to a Fast Ethernet connection tap or to a Token-Ring network MsAU
connection (if the Token-Ring Telemetry option is installed).
z Access to the ATM connection to monitor.
z Access to an RS-232C connection (required only for Out-of-Band
communication).
z Access to a phone line and a modem within 50 feet (required only for Outof-Band communication using a modem connection).
NOTE
The MAC addresses for the probe can be found on the rear panel. It is a good idea
to make a note of the interface and its address prior to installing your probe
because some installation methods make it difficult to see the rear panel without
removing the probe.

“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 screws (included). Some

Connecting the Probe
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 communicating with the probe 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 link in case of a failure on your telemetry network.
The disadvantage of using only the serial connection is that it is a slower 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:

z 10Base-2 MAU (Agilent 28641B) - for ThinLAN cabling
NOTE
If the SQE test is available on the MAU, disable it.
Connecting to 10Base-T/100Base-TX Telemetry Networks
You can connect the probe to the network either by connecting the RJ-45
connector to a 10Base-T/100Base-TX half-duplex or full-duplex network or by
connecting the AUI connector to a 10MB/s Ethernet network.
52
Installation
Connecting the Probe
Use the following procedures to connect the probe’s RJ-45 connector to a 10MB/s
or 100MB/s Ethernet network for telemetry communications. Never use both the
AUI and RJ-45 connectors.
1. Connect the probe’s 10Base-T/100Base-TX (RJ-45) port, located on the rear
panel, to the network using a category 5 cable. Figure 3-5 on page 54 shows
how to connect the probe to a 10Base-T or 100Base-TX network.
2. Select RJ-45 as the Physical Connector parameter from the Modify/View
Interface Values menu.
3. If you are connecting to a device that supports the auto-negotiation protocol,
select Auto Negotiate for the Link Speed parameter from the Modify/View
Interface Values menu. Otherwise, select 10MB/s (for 10MB/s Ethernet) or
100MB/s (for 100MB/s Ethernet).
The probe will automatically negotiate the speed of the interface if the Link
Speed parameter is set to Auto Negotiate and if the connected device
supports the auto-negotiation protocol.
4. If you selected 10MB/s or 100MB/s for the Link Speed parameter, you must
also select Half-Duplex for the Full/Half Duplex parameter from the
Modify/View Interface Values menu.
53
Installation
Connecting the Probe
Figure 3-5: Connecting the Probe to a 10Base-T/100Base-T Network
Connecting to Token-Ring Telemetry Networks
The Token-Ring option must be installed to connect the probe to a Token-Ring
telemetry network.
CAUTION
Connecting the Token-Ring interface to your network when the interface is
configured to the wrong network speed (4Mb/16Mb) can cause disruption of all
traffic on your network and it will prevent the probe from properly inserting into
the ring.
You can configure the Token-Ring Speed from the Modify/View Configuration
Values Menu. The probe is configured with a default setting for 16Mbps
networks.
You connect the Token-Ring interface to your network by using the appropriate
cables. The probe has both RJ-45 and DB-9 connectors on the rear panel for
connecting to Token-Ring networks. Figure 3-3 on page 51 shows the back panel
with the Token-Ring option installed.
54
Installation
Connecting the Probe
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.
Token-Ring networks typically 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 to any open port of a Media Station 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.

If your network uses the Token-Ring Data Connectors, you need a Type 1 cable
with a Token-Ring Data Connector on one end and a DB-9 connector on the other
end to connect the probe to the ring. Connect the Token-Ring Data Connector plug
to any open port (excluding the RI or RO ports) of a MsAU and connect the DB-9
connector to the probe’s DB-9 connector. Figure 3-8 on page 57 shows the TokenRing interface connected to a Type 1 MsAU using Token-Ring Data and DB-9
connectors.

About the Information in the Following Sections
It is assumed that you understand the basic terminology and concepts of ATM
network test interfaces.
Comprehensive coverage of network test connections and physical layer testing is
beyond the scope of this Installation/User’s Guide. Consequently, the information
provided here covers only the basics, and only very common or generic
connection schemes are shown.
Connecting to an OC-3 ATM Network (In-Band)
To connect the probe to an OC-3 ATM network, you connect the probe in-line
with the network connection by using the two fiber-optic connectors and a
fiber-optic cable. Figure 3-9 on page 58 shows the details of the OC-3 interfaces.

Figure 3-9: Close-up of the OC-3 Interfaces
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:
NOTE
If the output of the probe’s OC-3 ATM Interface is transmitted into a multi-mode
fiber without using a 10db attenuator, it can saturate the receiver’s photodiode and
cause bit errors, but no damage can occur. You can order a set of 2 10dB
attenuators from Agilent (Agilent J2928A).
58
Installation
Connecting the Probe
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 in Step 1. Figure 3-11 shows how to connect the 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.

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:
z 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).
z Optical Splitters are used when you want to passively monitor network
traffic. You can order a multi-mode SC-to-SC Optical 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 interruption. The result is no interruption 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.
60
Installation
Connecting the Probe
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
appropriate for this example.
63
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 (refer
to “Connecting to the Network (Out-of-Band)” on page 50) and then refer to your
NetMetrix documentation to configure the following probe parameters:
z
z

Serial Port IP Address
Serial Port Subnet Mask
Serial Port Speed
Hardware Flow Control (if unsure, ask your local network administrator)
Modem Init String
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).
64
Installation
Connecting the Probe
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 work with low-speed and medium-speed
Hayes compatible modems. The following modem settings are recommended for
low-speed to medium-speed modem connections:
Modem Flow Control:
Data Compression (if applicable):
Error Correction (if applicable):
Off
Off
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:
Carrier Detect:
Data Compression:
Error Correction:
Hardware Flow Control (RTS/CTS signaling)
Always On
Enabled

After appending the appropriate commands to the modem initialization string,
warm start your probe.
Refer to your NetMetrix documentation for information on how to establish
communications with the probe over the SLIP link.
65
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 management
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 server method of configuration, do not attach 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.
68
Installation
Verifying the 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 activity. 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
Activity
State
Flashing, if connected to a network with traffic, or may
appear to stay on solid during periods of steady traffic.
~ Line On or Power

You can use NetMetrix to verify that the probe can be reached (refer to your
NetMetrix documentation).
69
Installation
Verifying the Installation
Out-of-Band Troubleshooting
For the Ethernet or Token-Ring telemetry interface, if the Activity LED is off,
verify that the probe is properly connected to the telemetry network and that there
is traffic on the network. Also, verify that you have the correct Physical Connector
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 verification of installation. If you have an option installed, 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 still having difficulty, call your
local Agilent service representative. For the Ethernet telemetry interface, continue
with the following “Ethernet Telemetry Interface” section.
Ethernet Telemetry Interface
If you selected Auto Negotiate for the Link Speed parameter, verify that the
connected Hub or switch supports this mode of operation. If you are not sure,
configure the link speed and full-duplex or half-duplex manually.
CAUTION
If you manually selected the Link Speed, be careful to configure it correctly. If
you configure the Link Speed for 100 MB/s and you connect the probe to a
10MB/s network, the probe will generate 100% utilization for that segment.
If you manually selected the link speed, verify that you are using the correct
speed. Also, if you manually selected the link speed, verify that you are using the
correct mode of operation (full-duplex or half-duplex). 10MB/s Ethernet is always
half-duplex.
If you are still having difficulty, call your local Agilent service representative.

Installation
Verifying the Installation
OC-3 ATM Troubleshooting
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
Probe Configuration Using a Bootp Server
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 system acting as a Bootp server. The system
that is operating as the Bootp server must be connected to your network. 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 subnet, the router
involved must support Bootp Relay (the transfer of a Bootp request). For example,
if you have multiple probes that you want to configure from a single 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 probes. You can configure multiple probes on one subnet and
then place them on their respective segments.

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 machine 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.
NOTE
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.

Starting the PC Bootp Server
You can start the PC Bootp server in one of the following ways:
z As a standalone executable program by entering the following:
bootpd -a IP address -s
z As a TSR (terminate-and-stay-resident) program by entering the following:
bootpd -a IP address
85
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 the Bootp daemon
to continually service bootp requests. This is preferable, since the Bootpd 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 packet and detects that the file has been updated. If hosts are 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 to the probe and to a power source (either 100120/VAC or 220-240/VAC). The probe 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), the probe automatically broadcasts Bootp requests that
trigger the Bootp server to provide its configuration parameters.

Restarting the Probe
The probe can be restarted by performing a warm start or a cold start. In either
case, the probe executes self-tests and re-initializes. There are differences in the
effects of each type of restart.
z A warm start resets the probe’s measurement data only.
z A cold start resets all of the probe’s measurement data, filters, alarms, and
user-defined statistics studies (excluding communications configuration
parameters) back to default values.
Warm Start
A warm start resets the probe’s measurement data only. You can warm start the
probe by doing one of the following:
z Cycling power (or a power outage).
z Selecting the menu item Warm start and Exit from the probe’s Main Menu
when you have a local terminal connected to the probe, as described in Step
3 on page 96.
z Using NetMetrix to execute a probe warm start. Refer to your NetMetrix

If you are experiencing tftp transfer timeouts or read errors, use the following
procedure to verify that tftp is configured correctly on your workstation.
1. Verify tftpd functionality by copying the firmware file to another directory
using the tftp command.
# cd /tmp
tftp 127.0.0.1
get firmware
quit
2. If the previous step fails, the problem is due to the tftpd configuration on the
workstation.

OC-3 ATM Interface Cables
The OC-3 ATM circuit connection is made using two fiber SC connectors that
support 155.52 Mbps ATM traffic. Optional transceivers support multimode and
single-mode.
Fiber-optic cables come in many different configurations depending on the
equipment you are connecting and the power levels of the network you are
monitoring.
Table A-1 lists some OC-3 ATM cables and their part numbers. The OC-3
ATMProbe connectors are type SC. The 1 at the end of each AMP part number
indicates that the length of the cable is one meter and a 2 at the end of the part
number indicates a cable length of two meters, and so on.

Probe Memory Allocation
The memory allocated to each parameter depends on how much memory is
installed in the probe. The memory parameter values relate to the various items in
the RMON or the Agilent private MIBs. These parameters were valid at the time
of publication.
Table B-2 on page 131 shows the memory allocated to each parameter for the
available probe memory configurations. The memory allocation shown for each
memory amount column assumes that all of the available memory within the
probe is allocated to the identified parameter.
NOTE
The parameter values shown in Table B-2 on page 131 are approximate and
subject to change without notice.
Network Statistics and Trace buffers (packet capture buffers) are allocated
dynamically from the same memory allocation. The values shown for Network
Statistics assume that no Trace buffers are configured. If Trace buffers are
configured, the number of Network Statistics are reduced.

134
Agent
A node (or software/hardware on a node) that supplies network management
information.

condition such as LOS, LOF, or LOP is detected. Different AIS signals are sent
depending on the level of the maintenance hierarchy.
ANSI (American National Standards Institute)
The United States coordinating organization for voluntary standards.
ASCII (American Standard Code for Information Interchange)
Seven bit code providing a total of 128 upper and lower case letters, numerals,
punctuation marks, and control characters. Also referred to as CCITT Alphabet
Number 5.
Asynchronous
A transmission process such that there is always an integer number of units
between any two significant instances in the same signal but there is not always an
integer number of units between significant instances in two independent signals.
Asynchronous Transfer Mode (ATM)
Asynchronous Transfer Mode (ATM) is a fast packet-switched technology based
on fixed length cells. Data is divided into individual units and routed across an
ATM network in a constant stream. Unused packets are filled with idle cells.
Flexible bandwidth is possible with ATM - a service can use as many ATM cells
as it needs. Voice, video, and data can be sent in a consistent manner over an ATM
network, making ATM a valuable solution for many different services.
ATM Adaptation Layer (AAL)
The ATM Adaptation Layer isolates the higher layers from the specific
characteristics of the ATM Layer and provides a way to map data from variable
length frames into the fixed size of ATM cells. Different Adaptation layers are
used (AAL-1, AAL-3/4, and AAL-5) to implement different types of service.
135
ATM Adaptation Layer 0 (AAL-0)
ATM Adaptation Layer 0 (AAL-0) supports raw cell transport. It has an SARPDU header or trailer.
ATM Adaptation Layer 1 (AAL-1)
ATM Adaptation Layer 1 (AAL-1) supports constant bit rate data such as voice,
video, or other continuous user data. AAL-1 transfers data at a fixed speed. AAL1 contains a 47-byte payload and a 1-byte header.
ATM Adaptation Layer 3/4 (AAL-3/4)
ATM Adaptation Layer 3/4 (AAL-3/4) supports variable bit rate data with
connection oriented (type 3) or connectionless (type 4) data services. AAL-3/4
supports two modes of operation - Message Mode which is used for framed data,
and Stream Mode which is used for low-speed continuous data. AAL-3/4 contains
a 44-byte payload with a 2-byte header and a 2-byte trailer.
ATM Adaptation Layer 5 (AAL-5)
ATM Adaptation Layer 5 (AAL-5) supports variable bit rate data with connection
oriented or connectionless data services. AAL-5 was designed as a simple
protocol that assumes some of the functions such as error detection, timing and
other overhead information is accomplished by the next level protocol. AAL-5
contains a 48-byte payload with control information in the normal ATM 5-byte
header.
ATM Cell
An ATM Cell is a 53-byte protocol data unit made up of a 5-byte cell header and a
48-byte payload (information field).
ATM Layer
The layer in ATM that switches cells to their correct destinations within the
network.
ATMProbe

Auto-Negotiation
The process by which a probe determines the network speed and automatically
sets its own configuration to match that speed.
136
Bandwidth
The range of frequencies within which transmission equipment (such as electric
cable or fibre-optic waveguide) can transmit data.
Battery-backed RAM
The probe’s memory that contains a copy of the probe configuration. If power is
removed from the probe (either by unplugging the power cord or from a power
outage), this memory is preserved by power provided by the probe's internal
battery.
BIP-8
Bit Interleaved Parity 8 bits wide
Bit Interleaved Parity (BIP)
Bit Interleaved Parity (BIP) is a data integrity checking method. If even parity is
used, an N-bit code is generated by the transmitting equipment over a specified
portion of the signal in such a manner that the first bit of the code provides even
parity over the first bit of all N-bit sequences in the covered portion of the signal,
the second bit provides even parity over the second bit of all N-bit sequences and
so on. Even parity is generated by setting the BIP-N bits so that there are an even
number of 1s in each of the N-bit sequences including the BIP-N.
Bit Interleaved Parity 8 bits wide (BIP-8)
Bit Interleaved Parity 8 bits wide (BIP-8) provides for 8 separate even parity
codes covering the corresponding bit of each octet.
Bit Rate
The speed at which bits are transmitted, usually expressed in bits per second (bps).
bps
Bits per second.
Bridge
A device providing an intelligent connection between two otherwise independent
LANs. Bridges operate at layer 2 of the ISO OSI reference model. A bridge
inspects every packet originating on either LAN and creates a table of nodes and
137
their locations. It isolates the LANs from each other, allowing both sides to pass
traffic internally. If a transmission from one LAN is addressed to a node on the
other LAN, the bridge transmits it onto the other LAN for the destination node.
Broadcast address
The station address FFFFFF-FFFFFF. Packets intended for all nodes on a LAN
use this address as the destination address.
Broadcast packet
A packet sent to all nodes on a LAN.
Cell
A cell is a fixed-length packet of bytes.
Cell Delineation
Cell delineation is the process of identifying the beginning of cells. This can be
based on the HEC byte of individual ATM cells.
Cell Layer
A cell layer is the layer where cell level management, routing, traffic control and
multiplexing happen.
Cell Loss Priority (CLP)
CLP is a 1-bit field in the fourth byte in the header of an ATM cell. It is used to set
priorities for cell discarding. A CLP value of 0 gives the cell a 'higher priority'
telling the network this cell should not be discarded. A CLP value of 1 assigns the
cell a 'lower' priority informing the network that this cell can be discarded
depending on traffic conditions.
Cell Payload
A field of 44, 47, or 48 bytes in an ATM cell that carries service data.
Cell Segmentation
The process of mapping a service into an ATM cell stream.
Cell Stream
A continuous signal of ATM cells. Also known as stream.
138
CLIP (Classical IP)
IP over ATM conforming to RFC 1577.
CLP
Cell Loss Priority
Collision
The result of two or more nodes on a LAN transmitting at the same time,
producing a garbled transmission.
Common Part Convergence Sublayer (CPCS)
The Common Part Convergence Sublayer (CPCS) is a part of the ATM
Adaptation layer and provides message identification and error detection
depending on the AAL type being used.
Concentrator
An FDDI or Token-Ring network device that connects as a Dual Attachment
Station and has connections for additional devices (such as; stations,
concentrators, or bridges).
Connectionless-mode Network Protocol (CLNP)
The Connectionless-mode Network Protocol is a Network layer protocol which
has been defined by the International Organization for Standardization (ISO). A
complete description of the protocol is contained in ISO 8473, Information
processing systems - Data communications - Protocol for providing the
connectionless-mode network service.
Console
The ASCII terminal, or PC emulating an ASCII terminal that is connected to the
probe and used to configure, monitor, and troubleshoot the probe.
Convergence Layer
The Convergence Layer maps ATM cells into the transmission medium being
used. It is responsible for identifying the beginning of cells (cell delineation), and
for some simple management functions corresponding to the cell mapping. It also
decouples the rate of cell transmissions from the physical media by inserting and
removing idle cells.
139
Convergence Sublayer
The AAL is divided into two sublayers: the convergence sublayer and the
segmentation and reassembly sublayer (SAR). These two sublayers convert
whatever user data is to be transmitted into 48-byte cell payloads while
maintaining the integrity and a certain amount of identity of the data involved.
The result of each sublayer process is a Protocol Data Unit (PDU). The CS-PDU
is variable in length and is determined by the particular AAL and the length of the
higher layer data block passed to it. The SAR-PDU is always 48 bytes long to fit
in the payload of an ATM cell.
Convergence Sublayer Indicator (CSI)
The Convergence Sublayer Indicator (CSI) is a 1-bit field in the AAL-1 cell
format that handles clock recovery.
Convergence Sublayer Protocol Data Unit (CS-PDU)
A Convergence Sublayer Protocol Data Unit (CS-PDU) is a sublayer of the AAL.
See also Convergence Sublayer.
CRC (Cyclic Redundancy Check)
A mathematical algorithm to derive the frame check sequence (FCS) in bitoriented link protocols or the block check characters in character-oriented
protocols.
Cross Cell PRBS
A PRBS pattern inserted in successive cell payloads, crossing payload boundaries.
CSMA/CD (Carrier Sense Multiple Access/Collision Detection)
The network access-control mechanism that is based on collisions and utilized by
Ethernet networks. On contention-based networks, like Ethernet networks, each
station must detect an idle network prior to transmitting. If more than one station
transmits simultaneously, a collision occurs, all stations are notified, and the
colliding stations try retransmitting after waiting a random amount of time.
Customer Premises Equipment (CPE)
Customer owned equipment used to terminate or process information from the
public network. For example, a T1 multiplexer or a PBX.
140
Cycle/Stuff Counter (C1)
The Cycle/Stuff Counter (C1) is a 1-byte field in a PLCP frame that controls bit
stuffing and length indication. The C1 byte occurs in the P0 (12th) cell of a PLCP
frame. The value of C1 and its corresponding Trailer length is:

topology. The IEEE 802.3 standard evolved from Ethernet, but they are not
141
exactly the same. Network devices based on both standards can co-exist on the
same medium, but they cannot exchange data directly without special, bilingual
software that can decode packets of both types.
EtherTwist
The Agilent Company’s version of 10Base-T.
Extended LAN
A network consisting of two or more LANs that are connected by bridges, routers,
or other similar devices. Resources on the LANs can be accessed by users on any
of the LANs. See also LAN.
Far End Alarm and Control (FEAC)
The Far End Alarm and Control signal is used to send an alarm or status
information from the far end terminal to the near end terminal and to initiate
loopbacks from the far end terminal to the near end terminal. When there are no
status or alarm conditions, the FEAC has a value of all ones.
Far End Block Error (FEBE)
The Far End Block Error (FEBE) is a 4-bit field in the Path Status octet (G1) of a
PLCP frame. The value in the FEBE field is the count of BIP-8 errors received in
the previous frame (0000 through 1000). If FEBE checking is not implemented,
the field is set to all 1s (1111).
FEAC Signal

UNI cell. The GFC field is used for flow control in various ATM applications.
Two modes of operation have been designed for the GFC field - Controlled and
Uncontrolled. A GFC field set to all zeros denotes no flow control or uncontrolled
transmission. A GFC field set to some non-zero value indicates a flow control
condition or controlled transmission.

alignment, routing, operations or similar purposes.
Header Error Control (HEC)
The Header Error Control (HEC) is an 8-bit field and the fifth byte in the header
of an ATM cell. The HEC value is calculated from the first four bytes of the cell
header. If an error occurs in an ATM Cell header, it will be detected in the HEC
field. Cells with HEC errors that cannot be corrected are discarded by the
receiving node. The HEC field can also be used to determine the boundaries of a
packet for cell delineation.

have the same address. The address assigned according to the IEEE plan is
referred to as a device’s globally-administered station address. Some devices
provide an option for the user to assign a different station address that will
override the original. This type of address is referred to as a locally-administered
station address. The station address is also commonly called a MAC address,
Ethernet address, Token-Ring address, or physical address.

Physical Layer (PL)
Level 1 of the seven level OSI reference model defined by ISO. The physical
layer provides for the physical transportation of cells across the network. It
consists of physical medium dependent (PMD) and transmission convergence
(TC) sublayers. Important categories are PDH, SDH and the physical media used
on local premises for LANs.
Physical Layer Convergence Protocol (PLCP)
The Physical Layer Convergence Protocol (PLCP) is used to map cells into the
DS3 bit stream. There are 12 cells in a PLCP frame. Each cell is preceded by a 2byte framing pattern (A1,A2) to enable the receiver to synchronize to the cells.
After the framing pattern is an indicator consisting of one of 12 fixed bit patterns
used to identify the cell location within the frame (POI). This is followed by a
151
byte of overhead information used for path management. The entire frame is
padded with either 13 or 14 nibbles of trailer to bring the transmission up to the
exact bit rate used.
DS3 was intended to accommodate clock slips so PLCP frames have to be padded
with variable amounts to accommodate the extra “stuff” bits DS3 needs inserted
for this clock slip feature. The C1 overhead byte indicates the length of the
padding.
The payload and the overhead functions are checked by a Bit Interleaved Parity
(BIP) function to measure errors and performance degradation. This performance
information is transmitted in the overhead.
