Spirent TestCenter: How to set DRV to only use the Drop count from the expected Rx port instead of all the other ports that receiving the same stream ID?
Dynamic Results View - DRV
Use analyzer preload and add filter IsExpected > 0 in the DRV to remove flooded streams.
If you see unexpected streams show up as “Is Expected”, delete all analyzer streams if you had streams on analyzer before you enabled the preload.
One method to delete all analyzer streams is to first set "Delete inactive stream from memory". This can be found in Settings under the Traffic tab.
Next inactivate all streams and click apply.
Then set the Analyzer preload option if not already checked, then activate all streams and click apply.
Note that "Is Expected" column only works with Analyzer Preload.
If Analyzer Preload is not enabled, the "Is Expected" column will always show a value of "1"
There is a CR: 518517362 open to allow Analyzer Preload to be supported with Q-in-Q devices.
So currently if you have a configuration with Q-in-Q devices, the "Is Expected" column will not work since Analyzer Preload is not supported.
Work around is to use the Port Stray Frames column.
This can be enabled in Settings->L2L3 Results->Collect Stray Frames
Then in the DRV go to Streamblocks->Basic Counters
