 {{%notice note%}}
 - To use Noise Transfer Servo, you need to enable SyncE on the switch and on PTP interfaces. 
 - Cumulus Linux supports Noise Transfer Servo on Spectrum ASICs that support SyncE.
-- NVIDIA recommends you do not change the default Noise Transfer Servo configuration parameters.
 - NVIDIA recommends you use Noise Transfer Servo with PTP Telecom profiles. If you use other profiles or choose not to use a profile, make sure to set the sync interval to -3 or better.
