Spirent TestCenter : How do I adjust Tx port output frequency Parts Per Million (PPM) on 1 Gigabit cards or ports?
Environment/Versions
Spirent TestCenter
TX Clock frequency output settings
Answer
PPM adjustment is not supported on 1 Gigabit cards
IEEE 802.3 takes into consideration and allows up to +/- 100ppm tolerance levels.
If we observe packet drops at the line rate due to less clock tolerance levels on DUTs, only way is to reduce the traffic rate
