Importing an External Clock Source

Importing an External Clock Source

Context

An external clock source can provide reference time signals for devices. If the dynamic BMC algorithm is used, you can configure multiple 1588v2 devices to import external clock signals and enable these devices to participate in BMC calculation and then determine the grandmaster clock (GMC). The GMC can provide time signals for the entire 1588v2 network, and other 1588v2 devices need to obtain clock synchronization information from the GMC through 1588v2.

Perform the following steps on the 1588v2 device connected to an external clock source as required.

Procedure

  • Configure a PTP clock source.
    1. Run system-view

      The system view is displayed.

    2. Run clock source ptp synchronization enable

      Clock synchronization is enabled for the PTP clock source.

      By default, clock synchronization is disabled for a PTP clock source.

    3. Run clock source ptp priority priority-value

      A priority is configured for the PTP clock source.

      By default, a PTP clock source does not have a priority, indicating that it cannot participate in clock source selection. A smaller priority value indicates a higher priority.

    4. (Optional) Run clock source ptp ssm { dnu | prc | sec | ssua | ssub | unk }

      An SSM quality level is set for the PTP clock source.

      By default, no SSM quality level is set for a PTP clock source.

    5. Run commit

      The configuration is committed.

  • Configure a line clock source.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The view of the interface connected to the line clock source is displayed.

    3. Run clock synchronization enable

      Clock synchronization is enabled for the line clock source.

      By default, clock synchronization is disabled for a line clock source.

    4. (Optional) Run clock priority priority-value

      A priority is configured for the line clock source.

      By default, a line clock source does not have a priority, indicating that it cannot participate in clock source selection. A smaller priority value indicates a higher priority.

    5. (Optional) Run clock ssm { dnu | prc | sec | ssua | ssub | unk }

      An SSM quality level is set for the line clock source.

      By default, the SSM quality level of a line clock source is sent from the remote device.

    6. Run commit

      The configuration is committed.
