2. Select the PTP Trend Interval time setting.
The PTP Trend Interval setting is the extent of the horizontal axis on the
graph. Use the drop-down menu to change the interval to 1 minute, 5 minute,
10 minute, 30 minute, 1 hour, 3 hour, 6 hour, 12 hour, 1 day or 7 day.
NOTE.
The menu option for a 7 day trend interval has been removed. This option
will be reinstated in a future firmware release. Any presets that have been saved
with the 7 day trend interval will be changed to use the 1 day trend interval setting.

3. Close the settings box.
The PTP graphs are useful in observing the effects of traffic on the PTP messages
and the operation of transparent and boundary clocks. Non-PTP aware switches
may have significant PTP delay variations, while transparent and boundary clocks
will have much less variation and total delay.
