Configuring 1588v2 on a BC

Configuring 1588v2 on a BC

BC Deployment

As shown in Figure 14-15, NodeBs need to synchronize clocks with an external clock source. All devices on the bearer network support 1588v2. 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 external clock source. Devices are configured as BC nodes to connect to the external clock source, synchronize with the external clock source, 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 external clock source and send clock information to downstream devices.

Pre-configuration Tasks

Before configuring 1588v2 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 external clock source.

  • Configure synchronous Ethernet to synchronize the clock frequency on the network.

Configuration Procedure

The procedure of configuring 1588v2 on a BC is as follows.
