After you have configured the PTP master clock interface, enter the commit command
from configuration mode.
Example: Configuring a PTP Boundary Clock
This example shows how to configure a Precision Timing Protocol (PTP) boundary clock.
A boundary clock must include the configuration of at least one master and at least one
slave. The boundary master receives time from a remote master through the slave, and
in turn passes that time on to clock clients, which are in a slave relationship to the
boundary master. In this example, you configure a master, slave, clock source, and clock
client.
NOTE: ACX5048 and ACX5096 routers do not support boundary clock.

Requirements
This example uses the following hardware and software components:
NOTE: This example also applies to QFX Series switches. QFX Series switches
do not support Gigabit Ethernet interfaces. Instead, configure PTP boundary
clock parameters on 10-Gigabit Ethernet interfaces.

Junos OS Release 12.3 or later
Overview
In this example, the slave clock or clock client immediately receives announce and
synchronization packets after completion of the configuration.
