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 an HPE 5510 HI switch restores the default system time settings. Reconfigure the
settings after the switch starts up.
To specify the system time source:
1. Enter system view.
system-view
N/A
2. S
source.
clock protocol
{
none
|
ntp
}
By default,
the device uses the NTP
time source.
If you configure this command
multiple times, the most recent
configuration takes effect.
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:
1. Set the UTC time.
clock datetime
time date
By default, the UTC time is the
factory-default time.
2. Enter system view.
system-view
N/A
3. Set the local time zone.
clock timezone
zone-name {
add
|
minus
} zone-offset
The default local time zone is the
UTC time zone.
4. Set the daylight saving time.
clock summer-time
name
start-time start-date end-time
end-date add-time
By default, daylight saving time is
disabled.
