stratum: The stratum level at which the local clock operates, which is in the range of 1 
to 15.
 
Description 
Using the ntp-service refclock-master command, you can set an external reference 
clock or the local clock to be the NTP master clock. Using the undo ntp-service 
refclock-master command, you can remove the settings of NTP master clock.
 
X.X.X.X is not specified, and stratum is 1.
 
This command can set an external reference clock or local clock as the NTP master 
clock providing reference for time synchronization of other devices. X.X.X.X 
represents the IP address, that is, 127.127.t.u, of the reference clock. If it has not 
been specified, the local clock works as the NTP master clock by default. With this 
command, you can specify the stratum level where the NTP master clock operates.
 
Example 
Set the local device to be the NTP master clock at stratum 3, which provides 
reference for the time synchronization of other peers.
