Configuring NTP-PTP Interworking

Use this task to configure NTP to use PTP as the time source.
Before You Begin
PTP must be supported and enabled on the router before NTP-PTP interworking can be configured. If PTP
is not enabled, you receive an error message similar to the following when you try to commit the configuration:
RP/0/RP0/CPU0:router(config)# ntp master primary-reference-clock
RP/0/RP0/CPU0:router(config)# commit
% Failed to commit one or more configuration items. Please issue
'show configuration failed' from this session to view the errors
RP/0/RP0/CPU0:router(config)# show configuration failed
[:::]
ntp
master primary-reference-clock
!!% 'ip-ntp' detected the 'fatal' condition 'PTP is not supported on this platform'
!
end
Purpose
Use the master command with caution. It is very easy to override
Note
valid time sources using this command, especially if a low stratum
number is configured. Configuring multiple machines in the same
network with the master command can cause instability in time keeping
if the machines do not agree on the time.
Saves configuration changes.
• When you issue the end command, the system prompts you to commit
changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
◦ Entering yes saves configuration changes to the running configuration
file, exits the configuration session, and returns the router to EXEC
mode.
◦ Entering no exits the configuration session and returns the router to
EXEC mode without committing the configuration changes.
◦ Entering cancel leaves the router in the current configuration session
without exiting or committing the configuration changes.
• Use the commit command to save the configuration changes to the running
configuration file and remain within the configuration session.
