Latency tab:
User configures the following:
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.
Custom Rate per frame size:
The user can configure a custom rate in % or Mbps for each test frame. Tap on
Rate Table Config
. to configure rates for each frame. After making edits tap
Apply
to confirm edits or
Apply to
All
to apply rates to all tests.
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.

Frame Loss 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 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
