Configuring 1588v2 on an OC
OC Deployment
As shown in Figure 1, when two devices transmit wireless data on the IP bearer network, low-delay transmission must be guaranteed for real-time wireless services. The two devices function as OCs and transmit clock information through 1588v2 messages to ensure clock synchronization between them. OCs use 1588v2 messages to synchronize clock signals.
Pre-configuration Tasks
Before configuring 1588v2 on an OC, complete the following tasks:
Set link layer protocol parameters for interfaces to ensure that the link layer protocol status of the interfaces is Up.
Configure a grandmaster clock to correctly obtain clock and time signals from the external clock source.
Configure synchronous Ethernet to synchronize the clock frequency on the network.
