Go back to top

MX120+ Introduction

The MX120+ is part of the MX product family - in essence the MX120+ is similar to having two MX100+'s in one chassis. The default configuration of the MX120+ allows for single port operation (same as the MX100+), dual port operation, and pass through monitor mode.

Pass through monitor mode enables bidirectional monitoring between the two 100BaseFX/1000Base-X ports or the two 10/100/1000

Base-T ports.

Dual Port operation

When the dual port interfaces and software options are enabled, the test set can operate a combination of two ports at the same time with the following physical port operation combinations:

Port 1 10/100/1000Base-T and Port 2 10/100/1000Base-T (copper ports only)

Port 1 100Base-FX/1000Base-X and Port 2 100Base-FX/1000Base-X (fiber ports only)

Port 1 10/100/1000Base-T and Port 1 1000Base-X (copper and fiber port combination)

Port 1 and Port 2

Port 1 (Loopback) and Port 2 (any application)

Port 1 (any application) and Port 2 (Loopback)

Port 1 (Loopback) and Port 2 (Loopback)

Test Applications: When operating in single port operation, any of the following test applications are available. When operating in dual port operation, one port can run any of these test applications while the other port provides loopback.

BERT: Unframed / Framed Layer 1, and Framed Layer 2/3 Ethernet traffic generation with user selectable test pattern for Bit

6.6 Dual Port Navigation (MX120+ only)

When Dual Port mode is selected in the Home/Setup/Port menu, the MX120+ operates a combination of two ports independently. The

MX100+/MX120+_e-manual_D07-00-008P_RevC00

Setup shows what interface combinations are possible in dual port mode. Whatever the combination, the User Interface (UI) navigation remains the same.

If you are already familiar with the MX100+, then the MX120+ simply adds one small navigation change. This change is the port window and drop-down menu at the top of the screen.

If drop-down selection shows "P1" this means that the UI that you are currently viewing (including all associated configurations) all apply to port 1 only

If the selection is changed to "P2" this means that UI you are currently viewing (including all associated configurations) all apply to port 2 only

MX120+ Port Selection Window

The same navigation principle that is applied in the Home/Setup menu (shown above), applies when the test set is being operated in any of the test applications (BERT, RFC 2544, Throughput, Loopback).

An example of independent BERT applications running on port 1 and 2 are shown below.

Port 1 is configured for Layer 3 testing

Port 2 is configured for Layer 2 testing with VLAN tag

Both ports will run the same application (e.g., BERT & BERT, RFC & RFC, except for loopback mode), where any one port can be configured in loopback mode. Loopback must be configured first however, but the second port can run any selected application.

MX120+ Measurement Setup - Port 1 MX120+ Measurement Setup - Port 2

Dual Port Navigation and Operation Tips

MX100+/MX120+_e-manual_D07-00-008P_RevC00

If one port is going to be operated in loopback mode, first configure the desired port in loopback mode. Once completed, configure the second port with any application (BERT, RFC 2544, Throughput).

Remember to switch between ports, by selecting the correct port number from the top drop-down menu, when configuring both ports for operation.

Operating in dual port mode limits the same application to both ports, except for loopback.

Dual Port Testing

Even if the application on each port is the same, ports can still be operated independently. This applies to both the configuration and the start/stop of the results.

7.0 BERT

7.1 BERT Setup

Overview:

BER testing at Layer 1, 2, 3 and 4 is supported. The test can be configured to use either regular PRBS patterns, stress patterns or user defined test patterns to simulate various conditions. All patterns are encapsulated into an Ethernet frame to verify bit-per-bit performance of the circuit under test. Prior to testing, the test layer, frame header, traffic profile, error injection, and control settings of the far-end device (if applicable) must be configured.

Layer 1: Unframed mode (fiber ports only) or Framed mode

Unframed mode: Test traffic consists of a bit stream of the selected test pattern

Framed mode: Test pattern is encapsulated into a valid Ethernet frame with SOF, Preamble and CRC field

BERT Setup - Header (Layer 1 Unframed) BERT Setup - Header (Layer 1 Framed)

Layer 2: Framed BERT (same as Layer 1 Framed)

VLAN Tab: In the VLAN tab the following parameters are configured:

VLAN ID: Can be configured in the range 1 to 4094.

VLAN ID is the identification of the VLAN, which is basically used by the standard 802.1Q.

It has 12 bits which allows the identification of 4096 (2^12) VLANs.

Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved.

Maximum possible VLAN configurations are therefore set to 4094.

VLAN Priority: Can be configured in the range 0 to 7.

Set by the Priority Code Point (PCP), a 3-bit field which refers to the IEEE 802.1p priority.

It indicates the frame priority level from 0 (lowest) to 7 (highest), which can be used to prioritize different classes of traffic (voice, video, data, etc.).

Type: The following selections are possible:

8100 (IEEE 802.1Q tagged frame)

88a8 (IEEE 802.1ad Provider Bridging)

Drop Eligible: If enabled, drop eligibility flag will be set.

VLAN Flooding: Enable/Disable.

VLAN Flooding Range: Specifies the number of VLAN IDs. Enter a number from 0-4096. The VLAN IDs will be incremented by 1 until it reaches the number of times entered in the flood range.

CoS: Can be configured in the range 0 to 7.

Note: This field is three bits in length and maps directly to IP Precedence TOS bits to provide Class of Service (COS).

S-bit: Can be configured 0 or 1.

Note: The S field is one bit in length and is used for stacking labels. This is important as it is used to indicate the last label in the label stack.

TTL: Can be configured in the range 0 to 255. The default setting is 128 hops.

Note: Used to decrement the time-to-live counter.

8.0 RFC 2544 Conformance Testing

Overview:

Service providers often need to test the end-to-end performance of the link when deploying Ethernet services to customers. The Internet

Engineering Task Force (IETF) RFC 2544 “Benchmarking Methodology for Network Interconnect Devices” defines tests that describe the performance characteristics of a network interconnecting device.

RFC 2544 recommendations are well accepted in the test and measurement industry for network performance testing. The RFC 2544 test suite consists of and performs a set of four automated tests (throughput, latency, frame loss, and burst or back-to-back) to qualify the performance of a network link under test. The tests are especially popular for the verification of network links with certain service level agreements (SLA).

The following settings must be configured prior to RFC 2544 testing:

Test layer (Layer 1/2/3/4)

Frame header (MAC, VLAN, MPLS, IP, UDP, and Data)

Test frames selection

Pass/fail thresholds (optional)

Far-end unit loop control

8.1.4 Throughput, Latency, Frame Loss, and Burst Settings

The RFC 2544 test suite allows the user to run all of the four tests, one of the four tests, or a combination of any of the four tests. The user simply has to enable/disable which tests to perform by checking/unchecking a selection box in the respective tab for each test. By

MX100+/MX120+_e-manual_D07-00-008P_RevC00 default all of the four tests are enabled.

The following parameters must be configured before running the RFC 2544 conformance test suite.

Throughput tab:

Max Rate: Up to 100% of the negotiated line rate. The default value is 100%.

This is the maximum transmit rate to perform the throughput test for each test frame size.

The user may configure this rate as a % of the total line rate or in Mbps. For example, if the user configures the Max Rate to be 90% and the negotiated line rate of the link is 100Mbps, then the maximum transmit rate will be 90Mbps or 90% of the line rate.

Resolution: Input any value between 0.001% and 1%. The default value is 1%. Resolution refers to the resolution in searching for the throughput rate. If 1% is selected, the throughput rate will be searched with ±1% accuracy.

Duration: 5 to 999 seconds. The default value is 20 seconds.

The duration is the amount of time the throughput test is run for, for each frame size at a given rate.

Frame Loss Limit (%): Configures the frame loss tolerance used in the throughput rate search algorithm. If the frame loss count stays below the configured Frame Loss limit, the throughput rate search will stop, otherwise the throughput rate search will continue to the next step.

RFC 2544 Setup - Throughput

Go back to top

Latency tab: User configures:

Test: Throughput Rate or Custom Rate. The default value is throughput.

Throughput rate: Latency test will be performed at the throughput rate found for each of the tested frame sizes.

Custom rate: User configures a custom rate in % or Mbps.

Rate: Only available if Custom Rate is selected. Enter up to 100% of the negotiated line rate or enter the rate in Mbps.

Duration: 5 to 999 seconds. The default value is 20 seconds.

This is the amount of time that the latency test will be performed for each test frame size.

Repetitions: 1 to 100. The default value is 1.

This is the amount of times that the latency test will be repeated for each test frame size.

MX100+/MX120+_e-manual_D07-00-008P_RevC00

Go back to top

Frame Loss tab:

Max Rate: Up to 100% of the negotiated line rate. The default value is 100%.

This is the maximum transmit rate to perform the frame loss test for each test frame size.

The user may configure this rate as a % of the total line rate or in Mbps. For example, if the user configures the Max Rate to be 90% and the negotiated line rate of the link is 100Mbps, then the maximum transmit rate will be 90Mbps or 90% of the line rate.

Step Size: 1 to 10%. The default value is 10%.

The step size is the rate % that the frame loss test will be reduced by in the event of any frame loss. For example, if the

Max Rate is 100Mbps (or 100%) and frames are lost at this rate, then the transmit rate will be reduced to 90Mbps (or 90%).

The frame loss test will now be performed at the new rate until there is zero frame loss at two consecutive rate settings.

This means that the test will have to be performed at 80% (assuming that there was zero frame loss at 90%).

Duration: Selectable in the range of 5 to 999 seconds. The default value is 20 seconds.

The duration is the amount of time the throughput test is run for, for each frame size at a given rate.

RFC 2544 Setup - Frame Loss

Go back to top

Burst (Back-to-Back) tab:

Max Rate: The default value is 100%.

MX100+/MX120+_e-manual_D07-00-008P_RevC00

In the burst test, frames are always transmitted at the maximum rate for a given minimum and maximum burst duration.

Minimum Duration: Selectable in the range 2 to 999 seconds. Default value is 2 seconds.

This is the duration of the first burst.

Maximum Duration: Selectable up to 999 seconds. The default value is 20 seconds.

This is the duration of the second burst, which must be greater than the minimum burst.

Repetitions: Selectable in the range 1 to 100. The default value is 1.

This is the amount of times that the burst test will be repeated for each test frame size.

RFC 2544 Setup - Burst

Go back to top

8.1.5 Control Settings

Overview:

Asymmetrical links provide different line rates in the two directions. To verify the information for both the low and the high rates of the link, the user needs to send a test signal from one instrument located at one end of the link to an instrument at the other end of the link and vice versa to test traffic capacity. The two test instruments have to be synchronized, because the tests defined in RFC 2544 require the receiver to know the contents of the test signal to be transmitted in detail.

The MX100+/MX120+ offers an automated RFC 2544 test application to perform throughput, frame loss and burstability tests in a localremote unit setup. The user first configures the test setup in the local test set. Once initiated, the local unit transfers the setup information to the remote unit via the line under test. Upon completion, the remote MX100+/MX120+ transfers the test results back to the local

MX100+/MX120+, enabling the user to read the results for both directions of the link on the local unit.

8.1.6 Starting/Stopping an RFC 2544 Test

Once all configurations have been made, the user can start the RFC 2544 test. The following are two scenarios of how to prepare and start the unit for RFC 2544 testing.

Note: If testing on fiber ports, make sure the LASER is turned on before starting the test.

Far-End Unit in Manual Loopback Mode:

If the far-end unit (another MX) is already in a manual loopback mode, do not send a loop up command since it is not necessary

Once the correct control settings are configured, the user can start the test

The selected tests will run automatically. When all the tests are complete the test will stop automatically. If the RFC 2544 test suite needs to be stopped before they are done, then simply press the Stop button, located in the Action drop-down menu. The status of each selected test can be seen in the Results tab.

Far-End Unit Controlled with Loop Up/Down Commands

If the far-end unit is not manually looped back, then it must first receive a loop up command from the control unit before the RFC

2544 test suite can be started

To loop up the far-end unit with the manual mode loop up/down commands, configure the control settings mode to manual

Enter the MAC and/or IP address of the far-end unit

Send the loop up command by pressing Loop Up

Once the far-end unit has been looped back, start the test by pressing Start. When the all of the selected tests are completed, the RFC

2544 test suite will stop automatically. Once all tests have been completed and there is no need to test again, go back to the Control tab, and press the Loop Down button. This will send a loop down command to the far-end unit to remove the loopback that is in place.

Start the RFC 2544 test, and loop down the far-end unit when all tests have been completed.

9.0 Throughput Testing (Multiple Streams)

Overview:

The throughput application (or the multiple streams application) performs the following measurements:

Throughput performance

Frame loss analysis

Delay analysis

Frame/packet arrival analysis

Received traffic type analysis

Received traffic frame size analysis

MX100+/MX120+_e-manual_D07-00-008P_RevC00

On the transmit side, the throughput application allows for the configuration of up to 8 traffic streams with their own MAC and IP addresses, VLAN tags (up to 3 per stream), bandwidth/rate, frame size, and L2 and/or L3 quality of service (QoS) parameters. On the receiver end, the traffic is analyzed on a per stream (up to 8 streams) basis as well as a global or aggregate measurement.

This application is very useful in verifying the transport of traffic with different prioritization settings across a network link. The test helps verify that the network can handle high priority traffic and low priority traffic accordingly.

10.3 Definitions

10.3.1 802.3ah OAM Discovery

Discovery is the first phase of the 802.3ah protocol. During Discovery, local and remote units exchange Information OAM PDUs indicating capabilities and configuration information (e.g., mode, PDU size, loopback support, etc.). After successful negotiation, the OAM protocol is enabled on the link. If no OAM PDU is received after 5 seconds, Discovery is restarted. The device can be configured in Active or

Passive mode combinations.

10.3.2 IEEE 802.1ag Definitions

Maintenance Domain (MD): Management space on a network that is owned and operated by a single network provider. There is a maintenance level (from 0 to 7) to define the hierarchical relationship between domains. Maintenance domains can be nested but never intersect. MD is defined by Operational or Contractual Boundaries (e.g., Customer, Service Provider, Operator).

Maintenance Association (MA): Association of Maintenance. Elements that comprise the Maintenance domain.

Maintenance Elements can either be MEPs (End Points) or MIPs (Intermediate Points):

MEPs are at the edge of the network. They can generate and respond to OAM messages. A point-to-point EVC has only 2

MEPs, a multi-point EVC has multiple MEPs.

MIPs are located between the MEPs and can be used to isolate network problems. MIPs cannot generate OAM messages but can respond.

Maintenance Level: Identifies the network hierarchy. Higher Level = Largest network. Level information present in all OAM PDU frames.

Level 0,1,2 = Operator domain

Level 3,4 = Service Provider domain

Level 5,6,7 = Customer domain

Some terms differ between the two protocols. The chart below describes the differences.

10.3.3 Measurement Definitions

Continuity Check Messages (CCM)

CCM Messages are multicast messages sent from MEP to MEP at configurable intervals. Loss of continuity is detected after no CCM is received for 3.5 times the CCM interval.

Note: There can be 4,094 VLANs per port and up to eight maintenance levels. This yields a worst case CCM transmission rate of 9.8

million CCMs per second if 3.3ms interval is used.

Continuity Check Message (CCM)

RDI Flags added in CCM Messages indicates loss of continuity in the remote direction.

12.0 Loopback

The Loopback application in the main menu allows the user to establish a manual loopback on the test set. The loopback function is used when an end-to-end test needs to be performed with one of the test partners in software loopback mode. The Loopback function will loopback the incoming traffic to the test set back into the network under test.

The type of traffic that the loopback function loops back will depend on the type of test layer configured (Layer 1, 2, 3, or 4). Additional criteria can be set to allow only messages with specific criteria to be looped back. To specify loopback parameters, select the desired parameter and choose Enable from the drop-down menu. Tap on the box and input a value or select one of the drop-down menu choices:

Layer 1: All incoming traffic to the Rx loopback interface will be sent out unaltered to the Tx loopback interface.

Layer 2, 3, & 4 : In a Layer 2 or 3 loopback all incoming test traffic will be looped back.

The loopback function will swap the MAC destination and MAC Source addresses (for Layer 2) or MAC and IP destination and source addresses (for Layer 3).

All incoming frames with CRC errors will be dropped, similar to what an Ethernet switch does.

All broadcast and multicast frames will be dropped including any incoming unicast frames that have the MAC Source address equal to the MAC Destination address.

Loopback Parameters: The following parameters are available on Layer 2, 3 and 4. For more information on the parameters, please see 7.1.1 Header Settings in the BERT section. It is possible to enable any of these parameters to create a customer loopback filter. For example, if you enable a filter with VLAN 64, Priority 7, only traffic corresponding to these values will be looped back.

13.0 V-SAM

V-SAM (VeEX Service Activation Methodology) is an automated Ethernet service activation test feature conforming to the ITU-T Y.1564

standard, created to address and solve the deficiencies of RFC 2544:

• RFC 2544 was limited to test at the maximum throughput line rate for a single service. SAM is able to run multiple services on a single 10/100/1000 or 10G Ethernet line at a bandwidth ranging from 0 to the line rate, allowing for more realistic stream testing.

• The Frame Delay Variation, also known as (packet) jitter was not included in RFC 2544. Jitter is a critical parameter for real time voice and video services. It is now part of the SAM test suite.

• RFC 2544 validates the service parameters like frame loss, throughput and latency, one after the other, while SAM allows testing all the service critical parameters simultaneously. This results in significant time saving compared to RFC 2544.

Comparison of RFC 2544 and Y.1564

Test Methodology

MX100+/MX120+_e-manual_D07-00-008P_RevC00

The purpose of the SAM test suite is to verify that the service is compliant to its Bandwidth Profile and Service Acceptance Criteria. The test is broken down into two phases:

Phase 1: Service Configuration test : The services running on the same line are tested one by one to verify the correct service profile provisioning

Phase 2: Service Performance test : The services running on the same line are tested simultaneously over an extended period of time, to verify network robustness

Test Application

Phase 1: Service Configuration Test

The service configuration test is broken down into three steps. The steps are tested individually for all the services delivered on the same line.

Step 1: Committed Information Rate (CIR) Test : Traffic is transmitted at the CIR for a short period of time and the received traffic is evaluated against the Service Acceptance Criteria (FLR, FTD, FDV) measured simultaneously. The CIR test passes if the measurements on the received traffic stay below the performance objectives.

Step 2: Excess Information Rate (EIR) Test : Traffic is transmitted at the CIR+EIR rate for a short period of time; the EIR test passes if the received traffic rate is between the CIR (minus the margin allowed by the FLR) and CIR+EIR.

Step 3: Traffic Policing (Overshoot Test) : The purpose of the Traffic Policing Test is to ensure that when transmitting at a rate higher than the allowed CIR+EIR, the excess traffic will be appropriately blocked to avoid interference with other services. For this test, traffic is transmitted at 25% higher than the CIR+EIR for a short period of time. The test passes if the received traffic rate is at least at the CIR (minus the margin allowed by the FLR) but does not exceed the allowed CIR+EIR.

At this time the Committed Burst Size (CBS) and Excess Burst Size (EBS) tests are considered experimental and not an integral part of the standard.

Service Bandwidth Profile

Phase 2: Service Performance Test

Services running on the same line are tested simultaneously over an extended period of time, to verify network robustness. Service

Acceptance Criteria (SAC) including Frame Transfer Delay (FTD), Frame Delay Variation (FDV), Frame Loss Ratio (FLR) and Availability

(AVAIL) are verified for each service.

13.1.2 Bandwidth Profile

The Bandwidth Profile specifies how much traffic the customer is authorized to transmit and how the frames are prioritized within the network. Under the Bandwidth tab, the user specifies the following bandwidth criteria:

Traffic Flow (MX100+ only): Defines the Frame Size Type - Fixed or EMIX (Ethernet Mix)

MX100+/MX120+_e-manual_D07-00-008P_RevC00

Frame Size:

10000 bytes by tapping the value box.

For EMIX: The default value is abceg. Tap the zoom (magnifying glass) icon to define other values. Select the values from the drop down lists on the next screen.

Note: Any EMIX configuration of 5 frames is allowed.

V-SAM Services - Bandwidth V-SAM Services - Bandwidth MX100+ V-SAM Services - EMIX Configuration

CIR: Committed Information Rate. This is the guaranteed maximum rate at which the customer can send frames that are assured to be forwarded through the network without being dropped. Tap on the box to enter a rate and choose between IR Mbps or ULR

Mbps. Allowed values range from 0.01Mbps to the line bandwidth.

Information Rate (IR): Measures the average Ethernet frame rate starting at the MAC address field and ending at the CRC.

Utilized Line Rate (ULR): Measures the average Ethernet frame rate starting with the overhead and ending at the CRC.

Excess Information Rate (EIR): Maximum rate above the CIR at which the customer can send frames that will be forwarded on a best effort basis, but may be dropped in the event of congestion within the network. The combined CIR and EIR must not exceed the line bandwidth. Traffic beyond CIR + EIR will be dropped when it enters the carrier's network. Tap on the box to enter a rate.

EIR is expressed in terms IR Mbps or ULR Mbps. Select a term to express EIR or select Disable to disable the test.

Traf. Policing: Enable or Disable the traffic policing test. For this test, traffic is transmitted at 25% higher than the CIR+EIR. The

Policing test fails if the higher traffic rate is allowed through the network.

13.1.3 Thresholds

The user establishes Pass/Fail test criteria for the following Service Acceptance Criteria. Values define the minimum requirements to ensure that the service meets the Service Level Agreement (SLA):

FLR: Ratio of lost frames to the total transmitted frames.

FTD: Measures the transfer time that the frames can take to travel from source to destination. Values are measured in us, ms, or sec. Input a value within the digital range of .001-999 and 1 us-999sec. The user can also choose to Disable the FTD threshold evaluation. FTD will be measured regardless, but the value will not contribute toward passing or failing the service.

IFDV: Measures the frame jitter.

AVAIL: Minimum percentage of service availability allowed to still be compliant with the SLA. The service becomes unavailable if more than 50% of the frames are errored or missing in a one second interval. Availability is only guaranteed for traffic conforming to the CIR. Enter a percentage from 0-100. The user can also choose to Disable the AVAIL threshold evaluation. AVAIL will be measured regardless, but the value will not contribute toward passing or failing the service.

Go back to top

MX120+ Introduction

The MX120+ is part of the MX product family - in essence the MX120+ is similar to having two MX100+'s in one chassis. The default configuration of the MX120+ allows for single port operation (same as the MX100+), dual port operation, and pass through monitor mode.

Pass through monitor mode enables bidirectional monitoring between the two 100BaseFX/1000Base-X ports or the two 10/100/1000

Base-T ports.

Dual Port operation

When the dual port interfaces and software options are enabled, the test set can operate a combination of two ports at the same time with the following physical port operation combinations:

Port 1 10/100/1000Base-T and Port 2 10/100/1000Base-T (copper ports only)

Port 1 100Base-FX/1000Base-X and Port 2 100Base-FX/1000Base-X (fiber ports only)

Port 1 10/100/1000Base-T and Port 1 1000Base-X (copper and fiber port combination)

Port 1 and Port 2

Port 1 (Loopback) and Port 2 (any application)

Port 1 (any application) and Port 2 (Loopback)

Port 1 (Loopback) and Port 2 (Loopback)

Test Applications: When operating in single port operation, any of the following test applications are available. When operating in dual port operation, one port can run any of these test applications while the other port provides loopback.

If you are already familiar with the MX100+, then the MX120+ simply adds one small navigation change. This change is the port window and drop-down menu at the top of the screen.

If drop-down selection shows "P1" this means that the UI that you are currently viewing (including all associated configurations) all apply to port 1 only

If the selection is changed to "P2" this means that UI you are currently viewing (including all associated configurations) all apply to port 2 only

MX120+ Port Selection Window

The same navigation principle that is applied in the Home/Setup menu (shown above), applies when the test set is being operated in any of the test applications (BERT, RFC 2544, Throughput, Loopback).

An example of independent BERT applications running on port 1 and 2 are shown below.

Port 1 is configured for Layer 3 testing

Port 2 is configured for Layer 2 testing with VLAN tag

Both ports will run the same application (e.g., BERT & BERT, RFC & RFC, except for loopback mode), where any one port can be configured in loopback mode. Loopback must be configured first however, but the second port can run any selected application.

MX120+ Measurement Setup - Port 1 MX120+ Measurement Setup - Port 2

Dual Port Navigation and Operation Tips

MX100+/MX120+_e-manual_D07-00-008P_RevC00

If one port is going to be operated in loopback mode, first configure the desired port in loopback mode. Once completed, configure the second port with any application (BERT, RFC 2544, Throughput).

Remember to switch between ports, by selecting the correct port number from the top drop-down menu, when configuring both ports for operation.

Operating in dual port mode limits the same application to both ports, except for loopback.

Dual Port Testing

Even if the application on each port is the same, ports can still be operated independently. This applies to both the configuration and the start/stop of the results.

7.0 BERT

7.1 BERT Setup

Overview:

BER testing at Layer 1, 2, 3 and 4 is supported. The test can be configured to use either regular PRBS patterns, stress patterns or user defined test patterns to simulate various conditions. All patterns are encapsulated into an Ethernet frame to verify bit-per-bit performance of the circuit under test. Prior to testing, the test layer, frame header, traffic profile, error injection, and control settings of the far-end device (if applicable) must be configured.

Layer 1: Unframed mode (fiber ports only) or Framed mode

Unframed mode: Test traffic consists of a bit stream of the selected test pattern

Framed mode: Test pattern is encapsulated into a valid Ethernet frame with SOF, Preamble and CRC field

BERT Setup - Header (Layer 1 Unframed) BERT Setup - Header (Layer 1 Framed)

Layer 2: Framed BERT (same as Layer 1 Framed)

MAC Address: A default or user configured Media Access Control (MAC) address is added to the frame

8.1.5 Control Settings

Overview:

Asymmetrical links provide different line rates in the two directions. To verify the information for both the low and the high rates of the link, the user needs to send a test signal from one instrument located at one end of the link to an instrument at the other end of the link and vice versa to test traffic capacity. The two test instruments have to be synchronized, because the tests defined in RFC 2544 require the receiver to know the contents of the test signal to be transmitted in detail.

The MX100+/MX120+ offers an automated RFC 2544 test application to perform throughput, frame loss and burstability tests in a localremote unit setup. The user first configures the test setup in the local test set. Once initiated, the local unit transfers the setup information to the remote unit via the line under test. Upon completion, the remote MX100+/MX120+ transfers the test results back to the local

MX100+/MX120+, enabling the user to read the results for both directions of the link on the local unit.

10.3.2 IEEE 802.1ag Definitions

Maintenance Domain (MD): Management space on a network that is owned and operated by a single network provider. There is a maintenance level (from 0 to 7) to define the hierarchical relationship between domains. Maintenance domains can be nested but never intersect. MD is defined by Operational or Contractual Boundaries (e.g., Customer, Service Provider, Operator).

Maintenance Association (MA): Association of Maintenance. Elements that comprise the Maintenance domain.

Maintenance Elements can either be MEPs (End Points) or MIPs (Intermediate Points):

MEPs are at the edge of the network. They can generate and respond to OAM messages. A point-to-point EVC has only 2

MEPs, a multi-point EVC has multiple MEPs.

MIPs are located between the MEPs and can be used to isolate network problems. MIPs cannot generate OAM messages but can respond.

Maintenance Level: Identifies the network hierarchy. Higher Level = Largest network. Level information present in all OAM PDU frames.

Level 0,1,2 = Operator domain

Level 3,4 = Service Provider domain

Level 5,6,7 = Customer domain

Some terms differ between the two protocols. The chart below describes the differences.

Continuity Check Messages (CCM)

CCM Messages are multicast messages sent from MEP to MEP at configurable intervals. Loss of continuity is detected after no CCM is received for 3.5 times the CCM interval.

Note: There can be 4,094 VLANs per port and up to eight maintenance levels. This yields a worst case CCM transmission rate of 9.8

million CCMs per second if 3.3ms interval is used.

Continuity Check Message (CCM)

RDI Flags added in CCM Messages indicates loss of continuity in the remote direction.

12.0 Loopback

The Loopback application in the main menu allows the user to establish a manual loopback on the test set. The loopback function is used when an end-to-end test needs to be performed with one of the test partners in software loopback mode. The Loopback function will loopback the incoming traffic to the test set back into the network under test.

The type of traffic that the loopback function loops back will depend on the type of test layer configured (Layer 1, 2, 3, or 4). Additional criteria can be set to allow only messages with specific criteria to be looped back. To specify loopback parameters, select the desired parameter and choose Enable from the drop-down menu. Tap on the box and input a value or select one of the drop-down menu choices:

Layer 1: All incoming traffic to the Rx loopback interface will be sent out unaltered to the Tx loopback interface.

Layer 2, 3, & 4 : In a Layer 2 or 3 loopback all incoming test traffic will be looped back.

The loopback function will swap the MAC destination and MAC Source addresses (for Layer 2) or MAC and IP destination and source addresses (for Layer 3).

All incoming frames with CRC errors will be dropped, similar to what an Ethernet switch does.

All broadcast and multicast frames will be dropped including any incoming unicast frames that have the MAC Source address equal to the MAC Destination address.

Loopback Parameters: The following parameters are available on Layer 2, 3 and 4. For more information on the parameters, please see 7.1.1 Header Settings in the BERT section. It is possible to enable any of these parameters to create a customer loopback filter. For example, if you enable a filter with VLAN 64, Priority 7, only traffic corresponding to these values will be looped back.

13.0 V-SAM

V-SAM (VeEX Service Activation Methodology) is an automated Ethernet service activation test feature conforming to the ITU-T Y.1564

standard, created to address and solve the deficiencies of RFC 2544:

• RFC 2544 was limited to test at the maximum throughput line rate for a single service. SAM is able to run multiple services on a single 10/100/1000 or 10G Ethernet line at a bandwidth ranging from 0 to the line rate, allowing for more realistic stream testing.

• The Frame Delay Variation, also known as (packet) jitter was not included in RFC 2544. Jitter is a critical parameter for real time voice and video services. It is now part of the SAM test suite.

• RFC 2544 validates the service parameters like frame loss, throughput and latency, one after the other, while SAM allows testing all the service critical parameters simultaneously. This results in significant time saving compared to RFC 2544.

Comparison of RFC 2544 and Y.1564

Test Methodology

MX100+/MX120+_e-manual_D07-00-008P_RevC00

The purpose of the SAM test suite is to verify that the service is compliant to its Bandwidth Profile and Service Acceptance Criteria. The test is broken down into two phases:

Phase 1: Service Configuration test : The services running on the same line are tested one by one to verify the correct service profile provisioning

Phase 2: Service Performance test : The services running on the same line are tested simultaneously over an extended period of time, to verify network robustness

Test Application

Phase 1: Service Configuration Test

The service configuration test is broken down into three steps. The steps are tested individually for all the services delivered on the same line.

Step 1: Committed Information Rate (CIR) Test : Traffic is transmitted at the CIR for a short period of time and the received traffic is evaluated against the Service Acceptance Criteria (FLR, FTD, FDV) measured simultaneously. The CIR test passes if the measurements on the received traffic stay below the performance objectives.

Step 2: Excess Information Rate (EIR) Test : Traffic is transmitted at the CIR+EIR rate for a short period of time; the EIR test passes if the received traffic rate is between the CIR (minus the margin allowed by the FLR) and CIR+EIR.

Step 3: Traffic Policing (Overshoot Test) : The purpose of the Traffic Policing Test is to ensure that when transmitting at a rate higher than the allowed CIR+EIR, the excess traffic will be appropriately blocked to avoid interference with other services. For this test, traffic is transmitted at 25% higher than the CIR+EIR for a short period of time. The test passes if the received traffic rate is at least at the CIR (minus the margin allowed by the FLR) but does not exceed the allowed CIR+EIR.

At this time the Committed Burst Size (CBS) and Excess Burst Size (EBS) tests are considered experimental and not an integral part of the standard.

Service Bandwidth Profile

Phase 2: Service Performance Test

Services running on the same line are tested simultaneously over an extended period of time, to verify network robustness. Service

Acceptance Criteria (SAC) including Frame Transfer Delay (FTD), Frame Delay Variation (FDV), Frame Loss Ratio (FLR) and Availability

(AVAIL) are verified for each service.

13.1.3 Thresholds

The user establishes Pass/Fail test criteria for the following Service Acceptance Criteria. Values define the minimum requirements to ensure that the service meets the Service Level Agreement (SLA):

FLR: Ratio of lost frames to the total transmitted frames.

FTD: Measures the transfer time that the frames can take to travel from source to destination. Values are measured in us, ms, or sec. Input a value within the digital range of .001-999 and 1 us-999sec. The user can also choose to Disable the FTD threshold evaluation. FTD will be measured regardless, but the value will not contribute toward passing or failing the service.

IFDV: Measures the frame jitter.

AVAIL: Minimum percentage of service availability allowed to still be compliant with the SLA. The service becomes unavailable if more than 50% of the frames are errored or missing in a one second interval. Availability is only guaranteed for traffic conforming to the CIR. Enter a percentage from 0-100. The user can also choose to Disable the AVAIL threshold evaluation. AVAIL will be measured regardless, but the value will not contribute toward passing or failing the service.
