User
enables
or
disables
threshold settings for the throughput and latency tests.
When enabled, threshold settings can be configured for all of the test frames selected in the frame settings tab.
A Pass/Fail criteria will be applied when the threshold settings are enabled. Select a
rate type
from the drop-down menu
that will be used to determine pass/fail criteria. Options are % of Max Rate, % of Line Rate, Utlized Line Rate (Mbps).
For example, if the throughput threshold value for a 64 byte frame is configured for 80%, then a Pass criteria is
assigned if the throughput rate is 80% or better.
The threshold values for Throughput and Latency can be customized per user requirements. Tap on the selected
value to edit.
RFC 2544 Setup - Threshold Settings
13.4.1.4 Throughput, Latency, Frame Loss, and Burst Settings
The RFC 2544 test suite allows the user to run all 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 default all 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 1000 ULR (Mbps)
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. This can be
configured as a % of the total line rate or in Mbps.
Duration (s):
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.
