PTP Commands
ptp
Syntax [no] ptp
Context config>system
Description
This command enables the context to configure parameters for IEEE 1588-2008, Precision Time
Protocol.
This command is only available on the control assemblies that support 1588.
shutdown
Syntax [no] shutdown
Context config>system>ptp
Description
This command disables or enables the PTP protocol. If PTP is disabled, the router will not transmit
any PTP packets, and will ignore all received PTP packets. If the user attempts to do a 'no shutdown'
on hardware that does not support PTP, an alarm will be raised to indicate limited capabilities.
When ptp is shutdown, the PTP slave port is not operational. It shall not be considered as a source for
system timing.
Default
shutdown
clock-type
Syntax clock-type {{ordinary [slave]}
Context config>system>ptp
Description
This command configures the type of clock. The clock-type can only be changed when ptp is
shutdown.
The clock-type cannot be changed to master-only if PTP reference is no shutdown. In addition,
clock-type cannot be changed to master-only if there are peers configured.
Default
ordinary slave
Parameters
ordinary — The clock is capable of being either a PTP grandmaster or slave.
slave — The clock supports boundary-clock functionality (master and slave concurrently).
