76-8 config ntp master_stratum
Description
This command is used to configure the system clock (RTC) as an NTP master clock to which
peers synchronize themselves when an external NTP source is not available. Because the
implementation of NTP does not directly support the attached radio or atomic clocks, the router is
normally synchronized, directly or indirectly, to an external system that has such a clock. In a
network without Internet connectivity, such a time source may not be available. This command is
used in such cases. If the system has NTP master stratum configured, and it cannot reach any
clock with a lower stratum number, the system will claim to be synchronized at the configured
stratum number, and other systems will be willing to synchronize to it via NTP.
Format
config ntp master_stratum <value 0-15>
Parameters
master_strutum – the stratum value of master NTP server that the system will claim to be
