you can use the command ntp update-calendar for the hardware clock as per:

http://www.cisco.com/en/US/docs/ios/netmgmt/command/reference/nm_10.html#wp1096194


This way the hardware clock is synced from the ntp source.


If you want to sync the hardware clock from the software clock, then the command you can use is:

clock update-calendar

Yes, you only need ntp master and the stratum level you want to assign to it.


Example: router(config)# ntp master 2

And is there any way to set up the harware clock manual or this can be only via synchronization with the software clock.


thanks again
