Configuration Guide - Device Management

Procedure

1. Run system-view

   The system view is displayed.

2. Run ptp enable

   PTP is enabled globally.

   By default, PTP is not enabled globally.

3. Run ptp device-type oc

   The device type is configured as OC.

   By default, no device type is configured for a PTP device.

4. (Optional) Run ptp slaveonly

   The OC is configured to work in slave-only mode.

   By default, an OC port can be a master or slave port. When a device functions as an OC to synchronize with other clocks, configure the device to work in slave-only mode. After the device is configured to work in slave-only mode, ports of the device are in slave state. This indicates that the device can only function as a slave clock to receive clock signals from other clocks but cannot function as a master clock to provide clock signals for other clocks.

5. (Optional) Run ptp domain domain-value

   The PTP domain to which the device belongs is configured.

   By default, a PTP device belongs to domain 0.

   NOTE:

   Devices that perform clock synchronization through PTP messages must belong to the same PTP domain.

6. (Optional) Run ptp virtual-clock-id clock-id-value

   A virtual clock ID is configured for the device.

   Each device in a PTP domain has a virtual clock ID. By default, no virtual clock ID is configured for a PTP device, and the system generates a clock ID based on the MAC address of the device. You can configure a virtual clock ID to identify the device.

   NOTE:

   When running the ptp virtual-clock-id command, ensure that the configured virtual clock ID is unique in the entire PTP domain.

7. (Optional) Run ptp acl enable

   Access control of the clock source is enabled.

   By default, access control of the clock source is disabled.

8. (Optional) Run ptp acl-permit-clockid clockid-value

   A specified master clock source is added to the clock source whitelist.

   By default, no clock source whitelist is configured.
