ntp master — global
stratumno ntp master
Network Time Protocol (NTP) service
The router is not a master
This command configures the router as the master NTP server from which other NTP peers can receive their NTP time. (See the
command for setting peer values.) This command should be used with extreme caution, as it can declare the router’s clock to be stratum 1 (most accurate) without any safeguards about how accurate the clock really is.
The NTP stratum number for this server. The value can be 1 through 15.
