Introduction
This guide is designed to introduce you to the CN-100’s Ethernet Bit Error Rate Test (BERT) and to
provide a tutorial as to the functionality of the analyzer performing the BERT tests and the test results
provided. The BERT tests are incorporated in the CN-100 Manager GUI Tests.

3 Bit Error Rate Test Overview
The following BERT (Bit Error Rate Test) are designed to provide tests that users can use to
measure and report the performance characteristics of the network device. The CN-100 BERT
test provides a comprehensive test that can measure Bit Errors and can induce a known number of bit error’s to see how the DUT/SUT reacts to errors.

4 Port Configuration
The following instructions define how to configure the port mapping of the CN-100 for the BERT test. The
user may define the port parameters including MAC address, IP address and each individual IPv4 streams
to be used in the IPv4 BERT test.
1. Select Port Configuration
2. Set Port Test Type to LAN BERT3. Delete Existing streams or edit them.
4. Select Port 1 Configuration
5. Set Port Test Type to LAN BERT6. Define Port MAC Address
7. Define Port IP Address
8. Set Streams to IPv4 type, click IPv4 BERT.a. If streams already exist change stream type to IPv4 or
b. Add new IPv4 streams, set to IPv4 BERT
9. Click “OK”

5 Traffic Mapping
The following instructions define how to configure the port mapping of the CN-100 for the BERT test. The
user may configure the test source and destination ports.
6 Port BERT Parameters
The port BERT parameters tab allows the user to define the transmit and receive BERT pattern and insertederror rate if desired. The TX ID and RX ID, TX and RX pattern of the ports must match desired
configuration to function correctly.

7 BERT Status and Counters
The BERT status and counters is used to perform address learning, download confirmation, start/stop portsor groups of ports and display the following information:
Status: In frame or loss of frame.
RX Packets: Total number of Received BERT Packets.
RX Packets Rate: Current Rate of Received BERT Packets in packets per second.RX Bit Errors: Total received bit errors.
RX Bit Errors Rate: Rate of received bit errors.
Dynamic Bit Error Ratio: Error Bits/Total BERT frame bits.Static RX Bit Error Ratio: Error Bits/Total BERT Bits
RX BERT Words: Total Received BERT words.RX BERT bandwidth: Receive BERT packets Bandwidth.
Transmit Action: Start/Stop selected port.Insert: Inserts single Bit error.
Address Learning: For switch/router test to
Download Config: Download Current BERT parameters to CN-100.
Start group Tx: Starts transmitting allow ports.Stop Group Tx: Stop transmitting allow ports.
Clear Counters: Clears counters.

8 Ethernet Bit Error Rate Test Tutorial #1
This tutorial will walk you through the basic configuration of a Bit Error Rate Test. The test will transmit
traffic from the test source port through the system under test (SUT) or device under test (DUT). Please
configure the DUT/SUT so the traffic will be forwarded to the receive test ports. Each available test port
should be connected to the DUT/SUT with the appropriate cable for the DUT/SUT ports.
Once you have established a connection between the CN-100 Manager Software and the CN-100 chassisyou want to use for the test please follow the following steps.
1. Boot Up Chassis and connect appropriate Ethernet Management Cable or Serial cable on the back
of the chassis.2. Launch CN-100 Manager GUI.
3. Connect to the Chassis, a connection can be verified by the status bar on the bottom left corner of
the CN-100 Manager GUI.
4. Install a patch cord to connect the desired test ports. (with the cables connected a green link LED
should be seen on each of the connected ports)5. Select Port 1 Configuration
6. Set Port Test Type to LAN BERT
7. Define Port MAC Address
8. Define Port IP Address9. Set Streams to IPv4 type, click IPv4 BERT.
a. If streams already exist change stream type to IPv4 or
b. Add new IPv4 streams, set to IPv4 BERT
10. Click “OK”
11. From the main CN-100 Manager screen please click “tests”, select LAN IPv4 Frame BERT12. Define Port Traffic Mapping of the CN-100 transmit and receive.

13. Define BERT parameters, including PRBS pattern, error rate
14. Click “Down Load Configuration”
15. Click “Start Group TX”
16. BERT Status displays the counts and rates of the BERT test.
17. To insert Single Bit Error click “insert”
18. To change test parameters the test must be stopped first, than load new configuration prior to
starting new test.
