Configuring PTP Globally

Configuring PTP Globally

Context

If different carriers synchronize clocks with clients through the switch, configure the switch as a TCandBC. On a TCandBC, a BC interface receives clock signals from the master clock and sends the clock signals to a downstream device, and a TC interface only transmits clock signals. A TC interface on a TCandBC is responsible for forwarding PTP messages of PTP domains.

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 on a device.

  3. Run ptp device-type tcandbc

    The device type is configured as TCandBC.

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

  4. Run ptp domain domain-value

    The domain to which the BC interface of the TCandBC 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.

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

    A virtual clock ID is set for the device.

    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 also 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.

  6. (Optional) Run ptp acl enable

    Access control of the clock source is enabled.

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

  7. (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.
