Enabling 1588v2 Globally

Enabling 1588v2 Globally


When the master clock needs to transmit clock signals to multiple devices, configure the master node as a BC. A BC provides multiple physical ports to participate in 1588v2 time synchronization. One port receives clock signals from an upstream device, and the other ports send the clock signals to downstream devices.

Perform the following steps on each 1588v2 device.


  1. Run system-view

    The system view is displayed.

  2. Run ptp enable

    1588v2 is enabled.

    By default, 1588v2 is disabled on a switch.

  3. Run ptp device-type bc

    The 1588v2 clock mode is set to BC.

    By default, no 1588v2 clock mode is configured for a switch.

  4. (Optional) Run ptp domain domain-value

    A clock domain ID is specified.

    By default, a 1588v2 device belongs to domain 0.


    Devices in the same clock domain can exchange 1588v2 messages to synchronize the time.

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

    A virtual clock ID is set.

    By default, a 1588v2 device has only the default clock ID and does not have a virtual clock ID. The default clock ID is generated by padding fffe in the middle of the system MAC address. For example, if the system MAC address is 111122223333, the default clock ID is 111122fffe223333.

  6. (Optional) Run ptp max-steps-removed max-steps-removed-value

    The maximum number of hops is set.

    By default, the maximum number of hops is 255.

  7. Run commit

    The configuration is committed.
