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, it defaults to 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 a higher clock accuracy.
Usage guidelines
Usually 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 select a device that
has a relatively accurate clock from the network, and use the local clock of the device as the reference
clock to synchronize other devices in the network.
Use this 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.
<Sysname> system-view
[Sysname] ntp-service refclock-master 2
