Ntp-Service Reliable Authentication-Keyid - HPE FlexFabric 5930 Series Network Management And Monitoring Command Reference

Predefined user roles
network-admin
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 the command with caution to avoid time errors. As a best practice, adjust the local system time
to a correct value before you execute this command.
Examples
# Specify the local clock as the reference source, with the stratum level 2.

keyid: Specifies an authentication key number in the range of 1 to 4294967295.
Usage guidelines
When NTP authentication is enabled, a client can be synchronized only to a server that can provide
a trusted authentication key.
