Configuring the system time

Specifying the system time source

The device can use one of the following system time sources:
None—Local system time, which is manually configured at the CLI.
•
NTP—NTP time source. When the device uses the NTP time source, you cannot change the system
•
time manually. For more information about NTP, see Network Management and Monitoring
Configuration Guide.
If you configure the clock protocol none command together with the clock protocol ntp command, the
device uses the NTP time source.
Power cycling or using the reboot command to reboot an HP 5130 EI restores the default system time
settings. Reconfigure the settings after the switch starts up.
To specify the system time source:
Step
1. Enter system view.
2. Specify the system time
source.

Setting the system time

When the system time source is the local system time, the system time is determined by the UTC time, local
time zone, and daylight saving time. You can use the display clock command to view the system time.
A correct system time setting is essential to network management and communication. Set the system time
correctly or use NTP to synchronize the device with a trusted time source before you run it on the network.
To set the system time:
Step
1. Set the UTC time.
2. Enter system view.
3. Set the local time zone.
4. Set the daylight saving time.
