EXAMPLE
Console(config)#ptp e-latency 10
Console(config)#
ptp in-latency This command specifies the ingress latency added to the timestamp. Use
the no form to restore the default setting.
SYNTAX
ptp in-latency latency
no ptp in-latency
latency – The ingress latency added the actual timestamp.
(Range: 0-1000000 nanoseconds; Default: 0 nanoseconds)
DEFAULT SETTING
0 nanoseconds
COMMAND MODE
Global Configuration
COMMAND USAGE
Failure to make this correction will result in a time offset between the slave
and master clocks.
EXAMPLE
Console(config)#ptp in-latency 10
Console(config)#
ptp mode This command sets the operating mode to boundary clock or transparent
clock. Use the no form to restore the default setting.
SYNTAX
ptp mode {boundary-clock | disable |
transparent-clock {end-to-end | peer-to-peer}}
no ptp mode
boundary-clock – A boundary clock can have multiple network
connections and can accurately bridge synchronization from one
network segment to another.
disable – Disables PTP on the switch.
transparent-clock – A transparent clock modifies PTP messages
as they pass through the switch, updating the time stamps to
correct for time spent traversing the network.
end-to-end – This method measures the residence time
required for PTP event messages to cross from the input port to
