NOTE: ACX Series routers do not support transparent clock over MPLS
switched path.
NOTE: You might notice higher latency when you use copper SFP ports
instead of fiber SFP ports. In this case, you must compensate the latency
introduced by the copper SFP ports for the accurate CF (correction factor)
measurement.

Configuring Transparent Clock Mode for Precision Time Protocol
In a distributed network, you can configure transparent clock for Precision Time Protocol
(PTP) for synchronizing the timing across the network. Junos OS supports the
e2e-transparent CLI statement at the [edit protocols ptp] hierarchy level to configure
transparent clock for Precision Time Protocol (PTP).
NOTE: Starting in Junos OS Release 17.2 onwards, to configure PTP
transparent clock, include the e2e-transparent CLI command at the [edit
protocols ptp] hierarchy level. The transparent-clock CLI command to configure
transparent clock at the [edit protocols ptp] hierarchy level is supported only
in Junos OS Release 12.3X54.
To configure the transparent clock mode for Precision Time Protocol (PTP):
1. In configuration mode, go to the [edit protocols ptp] hierarchy level.
[edit]
user@host# edit protocols ptp
2. Specify transparent clock mode:
[edit protocols ptp]
user@host# set e2e-transparent
