from 0 to 3.

Description
Use the ntp-service refclock-master command to configure an external reference
clock or the local clock as an NTP master clock.
Use the undo ntp-service refclock-master command to cancel the NTP master clock
settings.
By default, no NTP master clock is configured. When ip-address is not specified, the
local clock is set to the NTP master clock by default. When stratum is not specified, the
local clock is located at stratum 8 by default.
You can use this command to designate an external reference clock or the local clock
as an NTP master clock to provide synchronized time to other devices. ip-address
specifies the IP address of an external clock as 127.127.1.u. If no IP address is
specified, the local clock is configured as the NTP master clock by default. You can
also specify the stratum at which the NTP master clock is located.
Example
# Specify the local clock as the NTP master clock to provide synchronized time for its
peers and locate the master clock at stratum 3.
