Precision Time Protocol (PTP) provides high-precision time synchronization
at an accuracy within the sub-microsecond range. PTP Version 2 (based on
IEEE 1588-2002) is used to provide clock synchronization for measurement
and control systems in a local area network.
Table 76: PTP Commands
Command Function Mode
ptp adjust Adjusts the system time based information in received
Sync messages
GC
ptp domain-number Specifies the PTP clock synchronization domain to
which the switch belongs
GC
ptp e-latency Specifies the egress latency added to the timestamp GC
ptp in-latency Specifies the ingress latency added to the timestamp GC
ptp mode Sets the operating mode to boundary clock or
transparent clock
GC
ptp priority1 Sets a preference level used in selecting the master
clock
GC
ptp priority2 Sets a secondary preference level used in selecting the
master clock
GC
ptp announce-receipt-
timeout
Sets the transmit timeout for PTP announcement
messages
IC
ptp delay-mechanism Sets the delay measurement method in a boundary
clock to use peer-to-peer or end-to-end mode
IC
ptp log-announce-interval Sets the announce message transmit interval IC
