Configuring 1588v2 on a TC

Configuring 1588v2 on a TC

TC Deployment

As shown in Figure 14-15, NodeBs synchronize with the external clock and support 1588v2. Core devices on the bearer network synchronize clocks with the grandmaster clock and send clock signals to downstream devices. Devices functioning as TCs transmit PTP messages between BCs or OCs. In this manner, BCs and OCs can synchronize their clocks. This deployment allows devices that do not have high clock requirements to only transmit 1588v2 messages, ensures synchronization precision, and improves synchronization efficiency.

Pre-configuration Tasks

Before configuring 1588v2 on a TC, 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 Grandmaster clock correctly receives clock and time signals from the external clock source.

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

Configuration Procedure

The process of configuring 1588v2 on a TC is as follows.
