Configuring a Clock Source

Configuring a Clock Source

Context

To implement clock synchronization on a switch, configure a clock source first. The switch supports Precision Time Protocol (PTP) and line clock sources. The configuration varies depending on the clock source. Follow one of the following procedures based on the clock source used in your network.

Pre-configuration Tasks

Before configuring a clock source, complete the following tasks:
  • Connect devices that require clock synchronization over the Ethernet using Ethernet interfaces to establish a clock synchronization network.
  • Connect the clock source to the clock synchronization network using an Ethernet interface.

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.
