Configuring PTP on a BC

Configuring PTP on a BC

BC Deployment

As shown in Figure 5-10, NodeBs need to synchronize clocks with the BITS clock source. All devices on the bearer network support PTP. Each device on the bearer network receives clock signals from an upstream device and sends clock signals to a downstream device. In this manner, NodeBs can synchronize clocks with the BITS clock source. Devices are configured as BC nodes to connect to a BITS device, synchronize with the BITS clock, and send clock information to other devices on the bearer network. Other backbone nodes on the bearer network are deployed as BCs, which can synchronize with the BITS clock source and send clock information to downstream devices.

Pre-configuration Tasks

Before configuring PTP on a BC, complete the following tasks:

  • Set link layer protocol parameters for interfaces to ensure that the link layer protocol status of the interfaces is Up.

  • Ensure that the BC obtains the clock signal and time signal from the BITS device correctly.

Configuration Process

The process of configuring PTP on a BC is as follows.
