Enabling the Transparent Clock 37.3
The IEEE1588 transparent clock is an intermediate device to connect the master and slave clocks. The
IEEE1588 transparent clock can effectively reduce time synchronization interference caused by switch's
delay processing and ensure ns-level time synchronization by verifying the dwell time when sync packets
pass through the transparent clock.
In global configuration mode, run the following command to enable the transparent clock:
Command Purpose
ptp enable
Enables the PTP transparent clock.
In global configuration mode, run the following command to shut down the transparent clock and delete all
already added PTP ports:
Command Purpose
noptp enable
Closes the PTP transparent clock.
The IEEE1588 clock synchronization protocol is independent from the underneath level protocols. It is based
on either Ethernet or IPv4/UDP. To enable the transparent clock to transmit and receive IPv4- or UDP-based
packets, you have to enable PTP in L3 port mode.
Run the following command in L3 port mode to enable PTP:
Command Purpose
ptp enable
Enables the PTP transparent clock.
