Throughput Testing
In Layer 2 Throughput testing, you can run a
BERT
between two testers.
See the
.
Layer 2 devices (switches) keep track of MAC address information in order to forward
traffic to the appropriate port, therefore each test set has to be configured with valid
source and destination MAC address.
Layer 2 testing is often performed to verify the quality of service provided over an
Ethernet network. Unlike a Layer 1
BERT
, the Layer 2
BERT
generates valid MAC
frames so that the test traffic can traverse through bridges and switches.
How to perform Layer 2 BER testing
Local Configuration
1. From the drop down
, select Throughput as the test type.
2. Configure the port.
Augo-Negotiation: On
Port Rate: Match the rate of the line under test; 10M, 100M, 1000M
Port Duplex: FULL
Pause: OFF
RJ-45 Polarity: AUTO
Pause Frame Delay: 0 ms
Pause: Off
Pause Frame Delay: 0 ms
Pause: Off
Pause Frame Delay: 0 ms
is on for testing.
3. Configure the
tab.
Test Type
: BERT
Test Layer
: Layer 2: Framed
• Set the desired frame size.
4. Configure the
5. Configure the
Traffic Shape
: Constant
•
Set the Constant Bandwidth at 100%.
•
Use the 2^31 test pattern.
Far End Tester Configuration
•
If performing this test between two units back-to-back, configure both units
as above.
•
If performing to a software loopback, configure the far end module as follows:
Test Mode
: LOOP BACK
Mode
: Manual
Layer
: Layer 1
•
Otherwise, make sure the far end has a hardware loop back.
