In a distributed network, you can configure Precision Time Protocol (PTP) master and
slave clocks to help synchronize the timing across the network. The synchronization is
achieved through packets that are transmitted and received in a session between the
master clock and the slave clock or clock client.
To configure Precision Time Protocol (PTP) options:
In configuration mode, go to the
