Configuration

The Configuration of the GM is partially done by the Preset and then by the Con-
figuration Tab under the Timing > External Reference (GM) section.
If the user selects the Custom Preset it might be able to configure the following
parameters when expanding (+) to the Advanced View for the GM source type:
3.7110.x
3.7110.2
3.7110.4
3.7110.7
The user can also configure the following parameters independently from the
chosen preset:
3.7110.x

Note:
PTP in management ports (Eth): In scenarios with a high load
of traffic, a non-optimal amount of timestamps is lost through cop-
per ports (eth management ports). However, this behavior does not
appear in optical ports. Hence, even though this functionality has
been saved to keep the compatibility with previous firmware archi-
tectures, it is not recommended to use PTP through management
ports.

external reference as PPS might be shifted
from 10MHz after each GNSS relock.
