Specifying the system time source as PTP
Specifying a PTP standard
Before configuring PTP, specify a PTP standard first. Otherwise, PTP cannot operate. Changing the PTP
standard for the device clears all PTP configurations defined by the standard.
To specify a PTP standard:
Step Command
Remarks
1.
Enter system view.

N/A
2.
Specify a PTP standard.

}
By default, no PTP standard is
configured, and PTP is not running
on the device.
Specifying the clock node type
You can configure only one of the following six types of clock nodes for a device: OC, BC, E2ETC, P2PTC,
E2ETC+OC, or P2PTC+OC.
Follow these guidelines when you specify the clock node type:
•
Before specifying the clock node type, specify a PTP standard first.
•
If the PTP standard is IEEE 802.1AS, the clock node type cannot be E2ETC or E2ETC+OC.
•
Changing the clock node type clears all PTP configurations except the PTP standard.
To specify the clock node type:
