(Required.)
Specifying a clock node type

(Optional.) Specifying the number of announcement intervals before the receiving node stops receiving
announce messages
(Optional.) Configuring the interval for sending Pdelay_Req messages
(Optional.) Configuring the interval for sending Sync messages

(Optional.) Configuring the correction date of the UTC
(Optional.) Configuring ToD clock parameters
(Optional.) Configuring a priority for a clock
(Optional.) Specifying the system time source as PTP
(Required.) Enabling PTP on a port
Specifying a PTP standard
Before you configure PTP, specify a PTP standard. 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.
system-view N/A
2. Specify a PTP standard.
ptp profile { 1588v2 | 8021as }
By default, no PTP standard is
configured, and PTP is not running
on the device.
Specifying a clock node type
You can configure only one of the following types of clock nodes for a device: OC, BC, E2ETC, P2PTC,
E2ETC+OC, or P2PTC+OC.
Follow these guidelines when you specify a clock node type:
• Before you specify the clock node type, specify a PTP standard.
•
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.
