Basic device management commands
clock datetime
Use clock datetime to set the system time.
Syntax
clock datetime time date
Default
The system time is the factory-default time.
Views

Predefined user roles
network-admin
Parameters
time: Specifies a time in the hh:mm:ss format. The value range for hh is 0 to 23. The value range for mm is 0 to 59. The value range for ss is 0 to 59. The leading zero in a segment can be omitted. If the seconds segment is 0 (hh:mm:00), you can omit it. If both the minutes and seconds segments are 0 (hh:00:00), you can omit both of the segments. For example, to specify 08:00:00, you can enter 8.
date: Specifies a date in the MM/DD/YYYY or YYYY/MM/DD format. The value range for YYYY is 2000 to 2035. The value range for MM is 1 to 12. The value range for DD varies by month.
Usage guidelines
|
|
CAUTION: This command changes the system time, which affects execution of system time-related features (for example, scheduled tasks) and collaborative operations of the device with other devices (for example, log reporting and statistics collection). Before executing this command, make sure you fully understand its impact on your live network. |
Correct system time is essential to network management and communication. You must configure the system time correctly before you run the device on the network.
The system time set by this command takes effect immediately. The device uses the clock signals generated by its built-in crystal oscillator to maintain the system time.
Examples
# Set the system time to 08:08:08 01/01/2019.
<Sysname> clock datetime 8:8:8 1/1/2019
# Set the system time to 08:10:00 01/01/2019.
<Sysname> clock datetime 8:10 2019/1/1

clock protocol
Use clock protocol to specify the system time source.
Use undo clock protocol to restore the default.
Syntax
clock protocol { none | ntp }
undo clock protocol
Default
The device obtains the UTC time from an NTP time source.

network-admin
Parameters
none: Uses the system time set by using the clock datetime command.
ntp: Uses NTP to obtain the UTC time. You must configure NTP correctly. For more information about NTP and NTP configuration, see Network Management and Monitoring Configuration Guide.
Usage guidelines
Correct system time is essential to network management and communication. You must configure the system time correctly before you run the device on the network.
· If you execute the clock protocol none command, the device uses the locally set system time. The device then uses the clock signals generated by its built-in crystal oscillator to maintain the system time.
· If you execute the clock protocol { ntp } command, the device obtains the UTC time through NTP and calculates the system time. The device then periodically synchronizes the UTC time and recalculates the system time.
The system time calculated by using the UTC time from an NTP or PTP time source is more precise.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Configure the device to use the local system time.
<Sysname> system-view
[Sysname] clock protocol none
clock summer-time
Use clock summer-time to set the daylight saving time.
Use undo clock summer-time to restore the default.
Syntax
clock summer-time name start-time start-date end-time end-date add-time

Default
The daylight saving time is not set.

Usage guidelines
Correct system time is essential to network management and communication. You must configure the system time correctly before you run the device on the network.
After you set the daylight saving time, the device recalculates the system time. To view the system time, use the display clock command.
Make sure all devices on the network are using the same daylight saving time as the local time.
Examples
# Set the system time ahead 1 hour for the period between 06:00:00 on 08/01 and 06:00:00 on 09/01.

Parameters
legal: Configures the banner to be displayed before a user inputs the username and password to access the CLI.
login: Configures the banner to be displayed before password or scheme authentication is performed for a login user.
motd: Configures the greeting banner to be displayed before the legal banner appears.
shell: Configures the banner to be displayed before a user accesses user view.
text: Specifies the banner message. You can enter the banner message on the same line as the keywords or on different lines. For more information, see Fundamentals Configuration Guide.

reboot
Use reboot to reboot the device.
Syntax
reboot [ slot slot-number ] [ force ]
Views
User view
Predefined user roles
network-admin
Parameters
slot slot-number: Specifies an IRF member device by its member ID. If you do not specify an IRF member device, the command reboots all IRF member devices.
force: Reboots the device immediately without performing software or hard disk check. If this keyword is not specified, the system first identifies whether the reboot might result in data loss or a system failure. For example, the system identifies whether the main system software image file exists and whether a write operation is in progress on a storage medium. If the reboot might cause problems, the system does not reboot the device.
Usage guidelines
|
|
CAUTION: · A reboot might interrupt network services. · Use the force keyword only when the device fails or a reboot command without the force keyword cannot perform a reboot correctly. A reboot command with the force keyword might result in file system corruption because it does not perform data protection. |
If the main startup software images are corrupt or missing, you must re-specify a set of main startup software images before executing the reboot command.
For data security, the device does not reboot if you reboot the device while the device is performing file operations.
Examples
# Reboot the device. Save the running configuration at prompt.
<Sysname> reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
Current configuration will be lost after the reboot, save current configuration? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
