PTP master clock capability for time of day/phase distribution is implemented on the following platforms:
7705 SAR-H with a GPS Receiver module
7705 SAR-Wx variants with a GPS RF port
7705 SAR-8 Shelf V2 with a GNSS Receiver card
7705 SAR-18 with a GNSS Receiver card
Time of day input must be enabled using the use-node-time command before the node can be used as a PTP grand master clock. GNSS must also be the active system time reference for nodes that are being used as a grand master clock. When the use-node-time command is enabled, the PTP master clock uses the system time as a source of PTP time and can be used for time of day/phase distribution. When the use-node-time command is disabled, the PTP master clock can be used for frequency only.
