PTP Ordinary Master Clock For Frequency

The router supports the PTP ordinary clock in master mode. Normally, a IEEE 1588v2 grand

master is used to support many slaves and boundary clocks in the network. In cases where

only a small number of slaves and boundary clocks exist and only frequency is required, a

PTP integrated master clock can greatly reduce hardware and management costs to

implement PTP across the network. It also provides an opportunity to achieve better

performance by placing a master clock closer to the edge of the network, as close to the slave

clocks as possible.
