VIAVI TestCenter: How does genConfigIndexStart, in stcbll.ini, affect the initial Stream ID?

• Under the [result] section of stcbll.ini, the setting genConfigIndexStart can be included (by default it is not there). For example:      [result]      genConfigIndexStart=123 • This value affects the stream ID on the first stream block on the first port in a STC configuration. • Note that if multiple tests are being run from the same PC/VM, they will all share the same starting Stream ID.  • There is a way to get around that. See FAQ19411 - VIAVI TestCenter: How does "Start index" in Settings -> Traffic Options tab -> Streams, work? • The number used is not a number per se, but rather a string of digits, where each digit is used as a multiplier and base 10 shift. • Step 1: Each digit is multipled by 65,536 • Step 2: The product from step 1 is then shifted over by the number of position that digit is in. • The result of the operation of each digit is then added together to result in the initial Stream ID. • For example, using genConfigIndexStart=123, STC would use the following initial stream ID calculation. • Digit by digit for "123" • 123 • step 1: 1 * 65,536 = 65,536 • step 2: 65,536 is base 10 left shifted over 2 places      65,536 23 • step 1: 2 * 65,536 = 131,072 • step 2: 131,072 is base 10 left shifted over 1 place      131,072 3 • step 1: 3 * 65,536 = 196,608 • step 2: 196,608 is base 10 left shifted over 0 places      196,608 • Attached is spreadsheet to help with this calculation.       • Please note that for genConfigIndexStart to take effect: • changes to stcbll.ini must be completed; and • then a new GUI instance needs to be launched. • This way, the new GUI instance will read the changes made to stcbll.ini .
