hello

i want to use the harware calendar of a 3925 router as a ntp server for the lan and i was wondering if the < NTP master > command is all i need? Or that command referce to the software clock . Im a little confused about that.

thanks

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

Example: router(config)# ntp master 2

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
