T-BERD®/MTS-5800 Network Tester
TCP Throughput Testing to an iPerf v3 Server
This document provides instructions on how to configure and execute TCP Wirespeed Throughput test
from a T-BERD/MTS 5800 instrument to an iPerf v3 server.
Equipment Requirements:
•T-BERD/MTS-5800 equipped with the
following:
oBERT software release V28.1 or greater
oEthernet and Layer4 test options:
▪C510M1GE and C5LSLAYER4 for
10/100 Megabit or 1 Gigabit Ethernet
▪C510GELAN and C510GLAYER4 for
10 Gigabit Ethernet
oSFP or SFP+ optical transceiver to match the
line under test
•Patch Cables to match the optical
transceiver and line under test (CAT5E,
Single mode or Multimode Fiber)
•Fiber optic inspection microscope (VIAVI
P5000i or FiberChek Probe)
•Fiber Optic Cleaning supplies
Figure 1: Equipment Requirements
The following information is required to complete the test:
•Physical Interface (10/100/1000BASE-T, 1000BASE-SX, 1000BASE-LX, 10GBASE-LR, etc.)
•Auto Negotiation settings of the port under test.
Fiber Inspection Guidelines:
•All fiber end-faces must be clean and pass
an inspection test prior to connection.
•Use the VIAVI P5000i, FiberChek Probe, or
Sidewinder microscope to inspect both
sides of every connection being used
(SFP/QSFP Port, bulkhead connectors,
patch cables, etc.)

Connect to Fiber Under Test (FUT):
1. For copper 10/100/1000BASE-T interface
testing with the T-BERD/MTS 5800v2,
connect the Port 1 10/100/1000 RJ-45 jack
to the port under test using CAT 5E or
better cable.
2. For copper 10/100/1000BASE-T interface
testing with the T-BERD/MTS 5800-100G,
insert a copper SFP into the Port 1
SFP+/SFP28 slot and connect to the port
under test using CAT 5E or better cable.
3. For optical interfaces:
•Insert desired SFP or SFP+ into the Port
1 slot on the top of T-BERD.
•Inspect and, if necessary, clean all SFPs,
fibers, and bulkheads, as described on
page 1.
•Connect the SFP, QSFP, or CFP4 to
the port under test using a Single
Mode or Multimode jumper cable
compatible with the interface
under test.
Launch and Configure Test:
1. Press the Power button to turn on the
test set and view the startup screen.
2. Using the Select Test menu, Quick Launch
menu, or Job Manager, launch an
Ethernet, Layer 4 TCP Wirespeed, IPv4,
Terminate test on port 1 for the desire
physical interface. For example:
Ethernet►10/100/1000►Layer 4 TCP
WIrespeed►IPv4►P1 Terminate.
3. If the test is not in the default settings, tap
the Tools icon , and select
. Press to
continue and wait for test to reconfigure.
4. Press the Setup Soft Key, to display
the Interface settings tab.If you are
testing a 10/100/1000 Electrical or 1GigE
Optical tests with auto negotiation
disabled, select the Physical Layer tab, and
configure settings to match the Ethernet
port under test.

5. Navigate to All Streams settings.
6. Configure appropriate Source IP, Subnet
Mask and Default Gateway parameters for
the TBERD 5800 test port, leave all other
parameters at defaults.

7. Navigate to TCP Host settings.
8. If the circuit under test uses VLAN tagging,
select Ethernet tab, set the Encapsulation
parameter to VLAN, and configure the
appropriate VLAN ID and Priority values.

9. Select TCP Host Settings tab.
10. Set the iPerf Version parameter to 3.
11. Set the Direction parameter to Upstream
to test in the TBERD 5800 to iPerf server
direction or to Downstream to test in the
iPerf server to TBERD 5800 direction.
12. Set the Connect to Server parameter to
the IP address of the iPerf server.
13. Set the Connect to Port parameter to TCP
port the iPerf server is listening on.
14. Set the Window Size parameter to
4194304 bytes.
15. If required adjust the Max Seg Size
parameter to match the circuit under test
configuration, otherwise leave at default.
16. If required configure the TOS or DSCP
values to match the circuit under test
configuration, otherwise leave at defaults.
17. Set the Transmit Mode parameter to Time
and set the Time parameter to desired test
duration in seconds.
18. Set the Number of Connections parameter
to desired value.
19. The T-BERD 5800 is configured for the test.
