The NEs in the same clock subnet can exchange clock information.
PTP Clock Subnet According to the actual networking situation, the network planning personnel need to divide the entire network into different clock subnets in planning the clock network. Within each subnet, time synchronization can be implemented for all clocks, to meet customer requirements. In this user interface, you can set the clock subnet to ensure that the clocks in the same clock subnet are synchronized according to the network planning.
BMC (Clock Subnet)
In this user interface, you can set the BMC algorithm that the local clock source uses, so that the system can calculate and select the best clock source according to the preset attributes, such as precision and priority.
