ntp-service refclock-master
Use ntp-service refclock-master to configure the local clock as a reference source for other devices.
Use undo ntp-service refclock-master to remove the configuration.
Syntax
ntp-service refclock-master [ ip-address ] [ stratum ]
undo ntp-service refclock-master [ ip-address ]
Default
The device does not use its local clock as a reference clock.

Parameters
ip-address: IP address of the local clock, which is 127.127.1.u, where u is the NTP process ID in the range
of 0 to 3. If you do not specify ip-address, i t d e f a u l t s t o 127.127.1.0 .
stratum: Stratum level of the local clock, in the range of 1 to 15. The default value is 8. A lower stratum
level represents higher clock accuracy.
Usage guidelines
Typically an NTP server that gets its time from an authoritative time source, such as an atomic clock has
stratum 1 and operates as the primary time server to provide time synchronization for other devices in the
network. The accuracy of each server is the stratum, with the topmost level (primary servers) assigned as
one and each level downwards (secondary servers) in the hierarchy assigned as one greater than the
preceding level.
If the devices in a network cannot synchronize to an authoritative time source, you can perform the
following tasks:
• Select a device that has a relatively accurate clock from the network.
• Use the local clock of the device as the reference clock to synchronize other devices in the network.
Use the command with caution to avoid time errors. Before you execute the command, HP recommends
that you adjust the local system time.
Examples
# Specify the local clock as the reference source, with the stratum level 2.
