Configuration Guidelines - HP 1910 User Manual

Configuring date and time
Configure the local clock as the reference clock, with the stratum of 2. Enable NTP authentication,
1.
set the key ID to 24, and specify the created authentication key aNiceKey is a trusted key. (Details
not shown.)
On Switch B, configure Device A as the NTP server.
2.
Select Device > System Time from the navigation tree.
a.
Click the Network Time Protocol tab.

Verifying the configuration
After the above configuration, you can see that the current system date and time on Device A is the same
as those on Switch B.

Configuration guidelines

A device can act as a server to synchronize the clock of other devices only after its clock has been
synchronized. If the clock of a server has a stratum level higher than or equal to that of a client's clock,
the client will not synchronize its clock to the server's.
The synchronization process takes a period of time. Therefore, the clock status may be unsynchronized
after your configuration. In this case, you can refresh the page to view the clock status and system time
later on.
If the system time of the NTP server is ahead of the system time of the device, and the difference between
them exceeds the web idle time specified on the device, all online web users are logged out because of
timeout. In this case, you can log in to the device again.
