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

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.

display diagnostic-information
Use display diagnostic-information to display or save operating information for features and hardware modules.
Syntax
display diagnostic-information [ hardware | infrastructure | l2 | l3 | service ] [ key-info ] [ filename ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
hardware: Specifies hardware-related operating information.
infrastructure: Specifies operating information for the fundamental features.
l2: Specifies operating information for the Layer 2 features.
l3: Specifies operating information for the Layer 3 features.
service: Specifies operating information for Layer 4 and upper-layer features.
key-info: Displays or saves only critical operating information. The device might have a large amount of operating information if an exception occurs or after the device runs for a long period of time. Specifying this keyword reduces the command execution time and helps you focus on critical operating information. If you do not specify this keyword, the command displays or saves both critical and non-critical operating information.
filename: Saves the information to a file. The filename argument must use the .tar.gz extension. If you do not specify this argument, the command prompts you to choose whether to save the information to a file or display the information.
Usage guidelines
You can use one of the following methods to collect operating statistics for diagnostics and troubleshooting:
· Use separate display commands to collect operating information feature by feature or module by module.
· Use the display diagnostic-information command to collect operating information for multiple or all features and hardware modules.
To save storage space, this command automatically compresses the information before saving the information to a file. To view the file content:
1. Use the tar extract command to extract the file.
2. Use the gunzip command to decompress the extracted file.
3. Use the more command to view the content of the decompressed file.
If you abort the display diagnostic-information command, the gunzip command might not be able to decompress the extracted file. To decompress the extracted file, export the extracted file to a PC that is running Linux, and use the gunzip -c command.
If you do not specify a file name for the command, the system prompts you to choose whether to display or save the information. If you choose to save the information, the system automatically assigns a file name and displays the file name in brackets. For file name uniqueness, the file name includes the device name and the current system time. If the device name contains any of the following special characters, the system uses an underscore (_) to replace each special character: forward slashes (/), backward slashes (\), colons (:), asterisks (*), question marks (?), less than signs (<), greater than signs (>), pipeline signs (|), and quotation marks ("). For example, device name A/B will change to A_B in the file name, as in flash:/diag_A_B_20160101-000438.tar.gz.
If you do not specify any feature parameters, this command displays or saves the operating information for all features and modules.
This command does not support the |, >, and >> options.
While the device is executing this command, do not execute any other commands. Executing other commands might affect the collected operating information.
Examples
# Display the operating information for all features and modules.
<Sysname> display diagnostic-information
Save or display diagnostic information (Y=save, N=display)? [Y/N]:n

Views
User view
Predefined user roles
network-admin
Parameters
slot slot-number: Specifies a device by its ID, which is fixed at 1.
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
