Spirent TestCenter: How to configure Dynamic Result View (DRV) to monitor Dead Streams/flows?

Environment/Versions
  • Spirent TestCenter
    • PGA
    • DRV - Dynamic Results View
    • Analyzer Preload
Answer
  •  To monitor the dead streams/flows the following need to be configured
    • 1.       The “Analyzer Preload” on all streamblocks should be enabled.
    • 2.       DRV filter condition should be set with StreamBlock.RxSigFrameRate = 0 (preferable
  •  Why Analyzer Preload need to be enabled to monitor the dead flows? 
    • Which pre-load the streamblock configuration information including expected Rx ports, Destination IP, Vlan etc. information to the port Analyzer.
    • If the expected streams do not reach the port(s), then analyzer able to apply the condition(s) set in the Dynamic Result View.
  • How to set the DRV and conditions!
    • 1.       Result Browser -> Change Result View
    • 2.       Select “Create Dynamic/Query View”
    •  
    • 3.       Name the DRV
    • 4.       Select the object (based on the requirement Default Port)
    • 5.       Counter(s) can be selected from the Counter Tab including
      • a.       Drop Frame count (based on Sequencer number)
      • b.      Frame Loss (based on TX-RX counters)
      • c.       Frame Loss Duration
        • Calculation is get the total bits of the lossed frames then divide by stream rate.
        • Ex. 128 byte frame = 148 * 8 = 1184 bits, if frame lost is 10, total bits lost is 11840 bits. If stream rate is 1,000,000bps, 11840/1000000 = 0.01184s = 11.84ms
      • d.      16 bit Analyzer Filter #4 (Expected Vlan ID)
      • e.      Headers such as port name, Expected Rx Port Name, Stream ID etc
    • 6.       Configuration Fields can be added to the result columns including
      • a.       Source IP address
      • b.      Destination IP address
      • c.       Vlan ID
    • 7.       Select and Insert Counters/config fields based on your requirement
    • 8.       Make sure you have added RxSigRate(fps) and/or Rx Sig Counts (Frames) since one of the field needed to set the condition to monitor the Dead Flows
    • 9.       Once Added the Fields click next to Add the Filter Condition for Dead Flows
      • a.       Click Add Filter
      • b.      Set the condition as follows StreamBlock.RxSigFrameRate = 0
      • c.       Any other filter conditions can be added with the above filter based on your requirement
      •  
    • 10.   Click next and Finish to complete the DRV
    • 11.   Refresh and check the results
