83-1 enable ptp
Description
This command is used to enable the PTP function globally. The device will enter the P2P-
transparent clock mode when the PTP global state is enabled. The PTP function can only work
when both the global PTP state and the per port PTP state are enabled.
When the stacking mode is enabled and the member ports of a trunk group exists in different stack
units, the PTP function will:
Execute normally when the sending and receiving of PTP messages are to member ports that are
on the same stack unit.
Execute abnormally, when the sending and receiving of PTP messages are to member ports that
are on different stack units.
Format
enable ptp
Parameters
None.
