SmartBits Chassis Models and Cards
SmartBitsChassisModelsandCards
SmartBits chassis models are available in several different models. The chassis you choose
will depend on the requirements of your system.
SmartCards are custom-designed printed circuit boards (PCBs) that fit within a SmartBits
chassis to generate, capture and track network traffic. They fit into the SMB-10, SMB2000, and SMB-200 chassis.
Modules consist of one PCB, but have a higher port density than the SmartCard. Each card
is attached to a tray specially designed for the SMB-600 and the SMB-6000B.
The term “card” can refer to any SmartCard or module.
The various models of SmartBits chassis are listed in Ta bl e 2- 1.:

• SMB-200 does not have the DB-37 connectors for the SmartBits stack configuration,
therefore does not support multiple users and the SMB-10 extension hub.
• SMB-200 has front panel Fan, Link, and Power LEDs, and a reset switch. The SMB-
2000 has only Power and Link LEDs and no reset switch.
• SMB-200 SmartBits System is the portable version of the SMB-2000 chassis.
• SMB-200 has a 4-slot chassis vs. SMB-2000 which has a 20-slot chassis.

Traffic Generation and Performance Analysis
Traffic Generation and Performance Analysis
Each SmartBits port physically generates one frame at a time, at a user-defined rate. The
port traffic can be varied, tracked, and analyzed in different ways, depending on the
processor technology of each card (Traditional, SmartMetrics, or TeraMetrics).
The following terms will assist you in understanding SmartBits terminology:
• Stream. A common template, pattern or packet structure based on a single protocol; a
single basic frame blueprint with a user-defined custom format or a selected standard
protocol format. A stream acts like virtual host on a SmartBits card and simulates the
traffic of a workstation or server on a network. Depending on the processor types, the
individual frames may or may not have specialized tracking and reporting capabilities.
• Traditional Stream. A single frame blueprint generated from a single port, with
varied frames generated via Variable Field Definitions (VFDs). These frames are
counted at the receiving ports but do not include a signature field for specialized
tracking.
• SmartMetrics Stream. Retains its own signature field with a unique timestamp and
sequence ID and may generate many varied frames with specialized tracking and
reporting capabilities. The signature field is the mechanism for advanced tracking and
analysis methods, namely latency histograms, sequence tracking of every frame, and
raw tag reporting.
• TeraMetrics Stream. Has SmartMetrics stream capabilities with special variations
available for very high speed technologies.
• Flow. An industry-wide term referring to transmitted traffic sent from point A to point
B, tracked based on unique source and destination combinations. In SmartBits
products and documentation, this term is used as an abbreviation for the term
SmartFlow described below.
• SmartFlow. A Spirent Communications term that is a superset of the above definition
of “flow.” A SmartFlow may include a single flow of traffic from point A to point B,
and may transmit many-to-one, one-to-many, or a set of different flows from either
receiving or transmitting ports for statistical analysis.
A SmartFlow is one or more frames from one or more sources to one or more destinations that are tracked as a single entity. The sources and destinations can be defined at
t he M AC , I P, T C P, o r U D P l ev e l .
SmartBits System Reference 19
Chapter 2: System Architecture
Traffic Generation and Performance Analysis
Traditional Cards and Traffic
The first series of SmartBits cards, called Traditional, generates one standard stream, or
one frame blueprint, plus one or two alternate streams per port, with the primary
processing located in the chassis controller.
For a summary of Traditional card features, please refer to Table 2-4 on page 22.
Each stream may also generate thousands of continuously varied frames by incrementing
or decrementing source or destination addresses, or varying the frame content via VFDs
(variable field definitions) in SmartWindow and SmartLib. These frame variations
exercise the DUT or system under test at up to full wire rate but do not have latency
measurements or out-of-sequence tracking for each frame.
Figure 2-6. Traditional Cards and Traffic
The Traditional architecture refers to the basic capabilities of all cards, including most or
all of the following features for the individual cards, available in SmartWindow and
SmartLib.
• Generate Packets Up to and Beyond Wire Speed. Uses a variety of transmission
modes, with the ability to dynamically vary packet gap and length during
transmission, adjust preamble length, auto negotiate speed and duplex mode, and
capture frames.
• Each Port Generates a Standard Stream. Also known as the Background template
or frame blueprint, the standard stream generated from a Traditional card is based on
one protocol (IP, UDP, or UDP) and capable of thousands of varied frames defined
through Variable Field Definitions (VFDs).
• Variable Field Definitions (VFD). You can use the three Variable Field Definitions
(VFDs) to customize a single stream per port in that each frame may be altered via
incrementing or decrementing data bits. For more details, refer to the glossary
definitions on page 340 and to the online help in the applications.
• Alternate Streams. In Traditional mode, there is an additional, simple Alternate
stream that can be defined, that is inserted in the traffic pattern at specified intervals
and can be used to simulate management frames. Gigabit Ethernet Cards have two
Alternate streams.
20 SmartBits System Reference
Chapter 2: System Architecture
Traffic Generation and Performance Analysis
• Round-Robin Traffic Loading. This method transmits the frame blueprints (streams)
in the sequence of the stream numbers, and repeats the sequence in a round-robin
fashion throughout the transmission.
• Customized Frame Content. You can customize frame content with a protocol
editor, including the ability to intersperse alternate traffic with regular streams and to
add VLAN tags.
• Tracking Frames via Triggers. You can monitor and validate packets with user-
definable triggers.
• Trigger. A pattern tracking tool that identifies any packet with a specific pattern
located inside any of the packets received by a receiving SmartBits card. The
receiving card then counts the number of triggers received with the specific pattern.
Most Traditional applications automatically insert triggers and add user-selectable
errors depending on the application.
Enhanced Traditional Architecture.
The Enhanced Traditional cards have the ability to increment and decrement source and
destination IP addresses, as well as MAC addresses.
This feature is only available with the following cards:
• GX-1420B, Gigabit Ethernet for the SMB-200/2000.
• GX-1421A, Gigabit Ethernet for the SMB-200/2000.
• LAN-3100A, 10/100 Mbps Ethernet for the SMB-600/6000B.
• LAN-3150A, 10/100 Mbps Ethernet RMII/SMII for the SMB-600/6000B.
For more details on these cards, refer to Chapter 9, “Ethernet Cards,”.
ATM with Traditional-Plus Architecture
ATM Cards are a type of Traditional card that have a single basic frame blueprint and can
retain hundreds or thousands of PVC/SVC addresses assigned per port, depending on
AT M t y p e .
Similar to the Traditional cards, ATM cards have additional capabilities, ranging from one
tracked trigger per port to over 2,000 triggers per port, depending on the card. For more
information, refer to Chapter 11, “ATM Cards,”.

SmartMetrics Cards and Traffic
The SmartMetrics processors are located on each card instead of on the chassis controller.
They offer Traditional mode as well as SmartMetrics mode performance analysis.
For a summary of SmartMetrics card features, please refer to Table 2-5 on page 25.For
details on individual cards, please refer to Chapter 9, “Ethernet Cards”.
The SmartMetrics mode offers extensive sequence and latency tracking, histograms, and
analysis for every frame via a time-stamped signature field inserted into each transmitted
SmartMetrics frame; this capability is also offered on TeraMetrics cards.
SmartMetrics Frame Blueprints
Hundreds of IP streams (frame blueprints), per port, feed into a sequenced, time-stamped
individually tracked series of frames (see Figure 2-7).
Within each stream, there can be thousands of “SmartFlows” per port. Each SmartFlow
within a stream carries the same protocol format but offers a number of variables which
are individually time-stamped and tracked according to the test configuration.
Chapter 2: System Architecture
Traffic Generation and Performance Analysis
Figure 2-7. SmartMetrics Frame Blueprints
SmartMetrics Signature Field
SmartMetrics mode, streams, and measurements support the use of an embedded Signature
field specific to each frame. The Signature field is used by the receiving card to analyze
network traffic and to display the results in spreadsheets and/or histograms.
The SmartMetrics Signature field resides in the last 18 bytes of the payload of each frame
and contains the following:
• Stream ID based on stream number, chassis, card slot, and port #.
• Frame sequence number.
• Transmit timestamp.
Important: If enabled, the Signature field overwrites the last 18 bytes of data at the end
of payload of each frame, therefore, do not insert significant data into that area.

Figure 2-8. Three Streams (frame blueprints) on a single SmartMetrics port
There are three different traffic loading methods used with SmartBits cards:
• Round-Robin Traffic Loading. The default transmit order for SmartCards that
support multiple stream definitions is a round-robin order based on the stream index.
One frame is sent from each stream definition starting at index 1 until all streams have
been transmitted. Then the process is repeated.
This means that the percentage of a given type of traffic is dependent on the number of
stream definitions that have been defined with the given characteristics. If thirty
streams are defined with a high QOS, and seventy streams are defined with a low
QOS, thirty percent of the traffic will have the high QOS.
• Sequencer Traffic Loading. This method sets the rate and transmit mode on a per-
port basis.

• Scheduler Traffic Loading. Available with the POS-6500 and LAN-6201 card
families, the Scheduler method allows you to specify rate (frames per second) on a
per-stream basis, unlike other cards where the traffic rate is set with a global, per-port
interframe gap. These cards can calculate the gap for you. If you oversubscribe the
card, (i.e., specify a combination of number of streams and frame rates that causes
more traffic than the medium is capable), an error is generated.
This feature provides the ability to set multiple rates on a single port, and allows you
to calculate percentages of different traffic types by setting frames-per-second on a
per stream basis.
For basic rate calculation, refer to the SmartLib User Guide.Foraquick,easyGUI
representation, you can also use the SmartWindow Rate/Load calculator, available in
the Transmit Setup for the POS-6500 and LAN-6201 cards.

Requirements for Multi-User Operation
Requirements for Multi-User Operation
To use the multi-user function, you must meet the following requirements.
• Use SmartBits applications that support multi-user operation. The following list
specifies the minimum version required for each program to use the multi-user
feature.
Applications with Multi-User Functionality
– SmartWindow 6.51
– SmartLib 3.07
– SmartApps 2.30
– SmartxDSL 1.01
– SmartMulticastIP 1.20
– SmartFlow 1.00
– SmartVoIPQoS 1.00
– SmartCableModem Test 1.10
– BGP Router Test 1.00
• A stand-alone SmartBits chassis must be Multi-User Ready. This includes all SMB-
600, SMB-6000B, SMB-2000 and SMB-10 chassis. [This excludes all SMB-200s.]
– SMB-600 and SMB-6000B: All SMB-600 and SMB-6000B chassis have
multi-user capability.
– SMB-2000 and SMB-10: All new SmartBits 2000 and SmartBits 10 chassis
have an identifying Multi-User Chassis label to support multiple users. To
check your chassis (controller) firmware version (must be version 6.60 or
later), connect to the chassis and select the application’s Help > About
command.
If you have an older chassis, you can retrofit your SmartBits chassis by purchasing the
hardware upgrade and sending the chassis to Spirent Communications to install the
SMB-2000 multi-user compliant backplane and controller firmware.
– SMB-200: The SmartBits 200 is a single-user only chassis and cannot be
accessed by multiple users in a stacking configuration or run multiple
programs simultaneously. However, it can be used in an expansion
configuration.
• ALL CONNECTED SmartBits chassis must be Multi-User Ready.
You can connect SMB-10s and SMB-2000s in a stack with the DB-37 connectors. If
one chassis is not Multi-User Ready, all other chassis are disabled from the multi-user
function.
Note: In a stacked multi-user environment of interconnected SMB-2000 and SMB-10
chassis, all chassis must be fitted with the multi-user compliant backplanes and firmware
in order to use the multi-user capability.
28 SmartBits System Reference
Chapter 3: Multiple Users Accessing a Chassis
Preparing for Multi-User Operation
In a multi-user environment, it is helpful to schedule and assign users to desired chassis
slots for specific time periods.
The SmartBits programs identify ports available to you and the ports reserved by other
users and are not available to you. When you have reserved one or more cards, you have
the ability to release them for other users to use.
Since your test requirements may dramatically vary at times and others may need the same
ports, we highly recommend that each multi-user location set up a scheduling board, either
posted or via a computer program scheduler.
The following example shows one style of scheduling boards. Design a schedule that is
best suited for your environment.

How Does the Multi-User Feature Work?
With the multi-user feature, SmartBits chassis can be accessed and used by a maximum of
10 users simultaneously, after the users have accessed the chassis sequentially and
reserved their necessary ports.
Multi-user chassis allow multiple users to connect to the same chassis simultaneously, as
long as they each use different cards in that chassis. While connected to a multi-user
chassis, users can reserve available ports and:
• run multiple applications
• run multiple instances of a program that supports multi-users
Evening

• run any other Spirent Communications application
SmartBits System Reference 29
Chapter 3: Multiple Users Accessing a Chassis
How Does the Multi-User Feature Work?
SmartBits programs that support the multi-user feature identify the available and
unavailable ports:
• through ownership LEDs on the main window of the program, or
• through ownership LEDs in reservations windows, or
• through multi-user checkboxes in card setup windows
The color convention of triangle LEDs (SmartWindow and SCMT) or circle LEDs (other
applications) next to port numbers or hub/slot/port numbers provides the following status
informatio shown in Figure 3-1:
Figure 3-1. Multi-User LEDs
Multi-user operation provides current status of each port and allows the user to change the
status by releasing reserved ports.
The following examples of multi-user functions demonstrate how the feature is used. For
more details, please refer to the user guide or online help for each supporting application.
• All reserved cards are released when you disconnect from the SmartBits chassis.
• You can connect SMB-200s, SMB-2000s, SMB-600s, and SMB-6000Bs via the
synchronizing Expansion RJ-45 ports. If you include an SMB-200 in the connected
series of chassis, all the chassis are disabled from the multi-user function. The SMB-
200isdesignedtobesingleuseronly.
• All connected SmartBits chassis must be multi-user ready in order to perform the
multi-user function.
• If you are working in a multi-user SmartBits chassis environment, you cannot test or
configure a port if you do not have ownership of that port.

Modules you have ownership of have an off-white background. Modules displayed with a
gray background are unreserved or owned by another user.
Ownership Status
Indicator
Figure 3-2. Ownership Status Indicator for the SMB-600
The ownership status indicator, located in the bottom left corner, displays the ownership of
the card in a multi-user environment, and is explained as follows:
• Blue – the card is reserved to you
• Green – the card is available to other users
• Red – thecardisreservedtoanotheruser
The ownership status light only reflects the status of the modules as of the most recent
refresh. It is possible in a multi-user environment for a module to be reserved by another
user in the time between the last refresh and your attempt to reserve the module.
Important: You cannot use a module unless you have reserved it. Note that once you
have connected to a chassis, the chassis link is independent of any modules reserved.
Therefore, even if no cards are reserved by you and all cards have been released or
reserved by other users, the chassis link will remain until disconnected.

You can run a test without manually reserving the ports. SmartFlow will automatically
reserve the test ports while the test is running, and automatically release them when the
test finishes. However, by not reserving the port prior to the test, the test may fail if
someone else reserved the port before you tried to start it.
Check a Port’s Availability after Connecting to the Chassis
Display the Card Setup tab that reflects the port’s current availability or click the Refresh
command. The SmartFlows > Traffic tab and Group Wizard reflect ports that were
available at the time you connected to the chassis, but do not show changes since that time.
What to Do if a Port is Unavailable
You can either select another port, omit that port from the test, or wait until the port is
again available.
Release a Port for Another User to Reserve
Select the Card Setup tab.ClicktheboxintheMultiuser field for the port. That will
clear the check mark.

Chapter 3: Multiple Users Accessing a Chassis
How Does the Multi-User Feature Work?
In SmartCableModem Test
Once connected to a SmartBits chassis, the SmartCard ports that are appropriate to SCMT
testing display their Port ID, Model number, and the multi-user ownership status of each
port. If you are the first user to access the SmartBits, all ports (blue status light) are
automatically reserved by you.
In the above SmartCableModem Test example, the ownership status light indicates the
multi-user status of each port:
• Blue – the port is reserved to you.
• Green – the port is available to other users (has been released by you). With a single-
user chassis, the port is a member of the Released Service Group, and acts like any
other group.
• Red – the port is reserved by another user. This color does not appear automatically; it
appears when you try to use the port or when you apply the Actions > Refresh button.
Ownership Status of All Ports
The ownership status light only reflects the status of the SmartCards since the initial
connection to SmartBits or since the last Refresh. It is possible for a port to be reserved by
another user in the time between the last refresh and your attempt to configure or use the
port.
To see the latest, most current ownership status of all ports, select the Actions > Refresh
command.

Chapter 3: Multiple Users Accessing a Chassis
How Does the Multi-User Feature Work?
Changing Multi-user Status
You must give ports a "Released" group (green status light) assignment in the Group
column to make those ports available to other users. The second user automaticallly
accesses and reserves all port numbers (now blue status for the second user) that have been
released by the first user. Therefore, the second user must give ports a "Released" group
(green status light) assignment in the Group column to make those ports available to the
third user.
If any user fails to give the Released group assignment to ports presented to him, all
subsequent users will access the SmartBits chassis and see no ports as available.
Cards reserved by you are released:
• when you disconnect from the chassis with the Actions > Disconnect command
or
• when you assign the Group column Released parameter to a port.
When you connect to a SmartBits chassis, all ports are automatically reserved for your use
unless otherwise specified in the Setup menu Preferences window or already reserved by
another user. While the chassis is reserved, it is not available to another user or to any
other Spirent Communications application.
When you connect to a multi-user chassis, only cards available (not in use by another user)
AND appropriate to the specific set of tests, will be displayed in Available Trunk and
Access ports columns.
By default, the program reserves all cards and releases cards not selected after 10 minutes.
However, if a test is begun during the 10-minute reserved time, the cards not selected will
not be released until the test finishes and a new 10-minute reserved time period expires.
In the Setup > Preferences window, you can specify that the program automatically
reserves all cards upon connection and does not release them after a time period.
To see all ports available in each chassis, select Setup > SmartBits Reservations.Upto8
chassis controllers may be accessed at one time; each chassis controller may control up to
4 chassis or 80 ports.
The ownership status light (left-hand LED) indicates the multi-user status of each port:
• Blue – the port is reserved to you.
• Green – the port is available to other users (has not been reserved by you).
• Red – the port is reserved by another user.
The ownership status light only reflects the status of the SmartCards since the initial
connection to SmartBits or since the last Refresh. It is possible for a port to be reserved by
another user in the time between the last refresh and your attempt to configure or use the
port.

Chapter 3: Multiple Users Accessing a Chassis
How Does the Multi-User Feature Work?
Multi-User
Status LEDs
To keep maximum resources available for testing, the SmartBits chassis does not update
SmartxDSL on the port status unless you click the Refresh button.
Changing Multi-user Status
Basic operations in viewing and changing user status include the following steps:
• To check the latest status of all ports, click the Refresh button.
• To release cards and make them available to other users, highlight the port row, and
click the Release button.
You must click the Release button to make ports available to other users. The second
user automaticallly accesses and reserves all available port numbers (now blue status
for the second user) and have been released by the first user. Therefore, the second
user must click on ports with a Release button to make those ports available to the
third user.
• To reserve cards released by another user or by yourself, highlight the port row, and
click the Reserve button.
To ensure that the port you have selected does not get reserved by another user prior to
running your test, reserve the port by highlighting the port and clicking the Reserve
button. While it is reserved, it is not available to anyone else either using another copy of
SmartxDSL or any other Spirent Communications application.
If any user fails to release ports presented to him, any subsequent users will access the
SmartBits chassis and see no ports as available.

Testing Frame Relay Switches
Applications available to set up and test frame relay switches:
• SmartWindow for a customized virtual front panel application.
• SmartLib for a programming library.
• SmartApplications for automated RFC-1242 testing.
Frame Relay testing uses the WAN SmartCards in the SmartBits 200 or 2000 chassis.
The Frame Relay switch is designed to support data in bursts and at high speeds in a bidirectional, conversational method of communication. The switch operates primarily on
Layers 1 and 2 of the network model, and works via a virtual circuit connection,inthat
dynamic links act like a pipe for moving traffic.
There are three types of virtual circuits:
• Switched (SVC). The SVC is similar to voice connections made through the
telephone network: when the network receives a connection request, it sets one up,
data is sent, and then the call is terminated.
• Permanent (PVC). The PVC is a point-to-point connection that is similar to a leased
data line. It is dedicated and used over long periods of time.
• Multicast (MVC). The MVC is a connection between groups of users, who can use
both SVCs and PVCs.
70 SmartBits System Reference
Currently, the PVC is the only type of Frame Relay circuit tested by SmartBits. The local
address for the Frame Relay switch is the data link connection identifier (DLCI).
Service fees are based on the committed information rate (CIR), which is equal to the
bandwidth available from one end to another. The frame size ranges from 32-bytes to the
maximum of 8,191-bytes.

Testing ATM
Chapter 7: Sample Test Topologies
Sample Devices and Networks to Test
Asynchronous Transfer Mode (ATM) is a connection-based technology. It requires that a
specific path be established between two endpoints before data can be transferred between
them.
The ATM series of SmartBits
ATM network traffic. Applications include testing:
™ compatible cards can be used to generate and monitor
• ATM-to-LAN internet working devices.
• Very high-performance ATM backbones.
• LAN-to-ATM edge devices.
Among the significant capabilities of these low cost/high performance ATM cards are:
• Frame-level testing at full-duplex, full-wire rate on edge devices and switches.
• Switch testing at full-cell rate.
• High-rate signaling testing for edge devices.
SmartWindow uses the concept of streams as a transmission engine. When you create a
stream, you define what to transmit, how and where to transmit it, and how fast to transmit it.
The what to transmit is the frame that a stream will use. Each time you create a stream,
you must give the card a data pattern (frame) to transmit for the specified stream. When
you click on the Start button, the stream transmits that data pattern repeatedly in its
assigned turn.
The how and where to transmit depend greatly on stream type and encapsulation. The two
stream types are Permanent Virtual Connections (PVC) and Switched Virtual Connections
(SVC). In ATM, one physical “pipe” is used to transmit and receive all data, but the pipe can
be divided into channels (as in television transmission). When a data cell is transmitted, its
data channel is indicated by two fields in the cell header that is included in each cell. These
are the Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) fields.
The how and where to transmit greatly depends on stream type and encapsulation.Thereare
two types of streams:
• Permanent Virtual Connections (PVC).
• Switched Virtual Connections (SVC).
For ATM, although there is one physical pipe that all data is transmitted and received on, it is
divided into channels much like it is for television. When a data cell is transmitted, the data
channel it belongs to is indicated by the Virtual Path Indicator (VPI) and the Virtual Channel
Indicator (VCI) fields in a Cell Header that accompanies every cell.

Feature Summary of 10/100 Mbps Cards
Comparison of ML-7710 vs LAN-3101A
The LAN-3101A module is a high-port density version of the ML-7710.
The single-port ML-7710 is used with the SMB-200 and SMB-2000. The 6-port LAN3101A module is used with the SMB-600 and SMB-6000B.
SmartLib Differences
In SmartLib Version 3.09 and higher, the following commands are used specifically for
the LAN-3101A and ML-7710:
• FST_CAPTURE_INFO (applies to both the ML-7710 and the LAN-3101A).
(None of the other "FST_CAPTURE_n" commands can be used with either the ML7710 or the LAN-3101A.)
• The following command is used to show data integrity errors:
ETH_EXTENDED_COUNTER_INFO and a parameter u64RxDataIntegrityErrors
(applies to LAN-3101A).
