Example for Configuring 1588v2 Time Synchronization

Example for Configuring 1588v2 Time Synchronization

Networking Requirements

In Figure 14-19, the bearer network carries wireless services between NodeBs, and all bearer network nodes support 1588v2. IN addition, NodeB1 and NodeB2 support 1588v2. In this way, wireless base stations and bearer network devices achieve frequency and time synchronization. Because all the devices on the bearer network support 1588v2, clock information can be transmitted in network-wide BC mode.

Figure 14-19  Networking diagram for clock synchronization

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure input of external clock signals.

  2. Configure the type of 1588v2-capable devices on the bearer network as BC.

  3. Configure PE1 and PE2 as system master clocks and connect them to external clocks. PE1 and PE2 back up each other.

  4. Set the delay mechanism to Pdelay.

Procedure

  1. Configure a clock source.

    # Configure PE1 to input clock signals from the PTP clock source to implement frequency synchronization. The configurations of PE2, CE1, and CE2 are similar to the configuration of PE1.
    <HUAWEI> system-view
    [HUAWEI] sysname PE1
    [PE1] clock ethernet-synchronization enable
    [PE1] clock source ptp synchronization enable slot 0
    [PE1] clock source ptp priority 10 slot 0
    [PE1] clock source ptp ssm prc slot 0
    

  2. Globally enable PTP and configure the device type as BC.

    # Configure PE1. The configurations of PE2, CE1, and CE2 are similar to the configuration of PE1.

    [PE1] ptp enable
    [PE1] ptp device-type bc slot 0
    

  3. Enable PTP on the interface.

    # Configure PE1. The configurations of PE2, CE1, and CE2 are similar to the configuration of PE1.

    [PE1] interface XGigabitEthernet 0/0/1
    [PE1-XGigabitEthernet0/0/1] ptp delay-mechanism pdelay
    [PE1-XGigabitEthernet0/0/1] ptp enable
    [PE1-XGigabitEthernet0/0/1] quit
    [PE1] interface XGigabitEthernet 0/0/2
    [PE1-XGigabitEthernet0/0/2] ptp delay-mechanism pdelay
    [PE1-XGigabitEthernet0/0/2] ptp enable
    [PE1-XGigabitEthernet0/0/2] quit
    [PE1] interface XGigabitEthernet 0/0/3
    [PE1-XGigabitEthernet0/0/3] ptp delay-mechanism pdelay
    [PE1-XGigabitEthernet0/0/3] ptp enable
    [PE1-XGigabitEthernet0/0/3] quit
    

  4. Verify the configuration.

    After completing the configurations, run the display ptp all command on CE1 and CE2 to view the PTP synchronization status. The following example uses the command output on CE1.
