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
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.
For the device to use the local system time, execute the clock protocol none command and this command in turn. The specified system time takes effect immediately. Then, the device uses the clock signals generated by its built-in crystal oscillator to maintain the system time.
A device power cycling operation restores the local system time to the default. After the device is power cycled, you must execute this command again to set the local system time.
Examples
# Set the system time to 08:08:08 01/01/2015.
<Sysname> clock datetime 8:8:8 1/1/2015
# Set the system time to 08:10:00 01/01/2015.
<Sysname> clock datetime 8:10 2015/1/1

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.
The device can use the locally set system time, or obtain the UTC time from a time source on the network and calculate the system time.
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 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 UTC 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

Parameters
job job-id: Specifies a process by its ID. The value range for job-id is 1 to 2147483647. If you do not specify a process, this command displays the statistics for the entire system's CPU usage (the total CPU usage of all processes). To view the IDs and names of the running processes, use the display process command. For more information, see Network Management and Monitoring Configuration Guide.
slot slot-number: Specifies an IRF member device by its member ID. If you specify a process but do not specify a member device, this command displays the statistics for the process on the master device. If you do not specify any options, this command displays the statistics for all processes on all member devices.
cpu cpu-number: Specifies a CPU by its number. If you specify a process but do not specify a CPU, this command displays the statistics for the default CPU. If you do not specify a process or CPU, this command displays the historical statistics for all CPUs.
Usage guidelines
After CPU usage monitoring is enabled, the system regularly samples CPU usage and saves the samples to the history record buffer. This command displays the most recent 60 samples in a coordinate system as follows:
· The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is rounded up or down to the closest multiple of the usage step. For example, if the CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded down to 50%.
· The horizontal axis represents the time.
· Pound signs (#) indicate the CPU usage. The value on the vertical axis for the topmost pound sign at a specific time represents the CPU usage at that time.
Examples
# Display the historical CPU usage statistics.

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.
To execute the display diagnostic-information command, make sure the CPU usage is less than 100% and the memory usage is equal to or less than 90%. To view the CPU usage and the memory usage, use the display cpu-usage and display memory commands.
While the device is executing this command, do not execute any other commands. Executing other commands might affect the collected operating information.

Parameters
summary: Displays brief information about system status, redundancy status, and NSR status. If you do not specify this keyword, the command displays detailed information about system status, redundancy status, and CPU role and status.
Usage guidelines
Before performing an ISSU or a switchover, execute this command multiple times to identify whether the system is operating stably. If the value of the System State field is not Stable, you cannot perform an ISSU. If the value of the Redundancy Stable field is not Stable, you cannot perform a switchover.
The device startup process takes some time. If the values of the status fields do not change to Stable, execute this command multiple times to identify the devices that are not in Stable state. You can also use other commands to identify the faulty components. For example:
· Use the display device command to identify the device operating status.
· Use the display system internal process state command in probe view to display service operating status.

Usage guidelines
To ensure correct operation and improve memory efficiency, the system monitors the amount of free memory space in real time. If the amount of free memory space decreases to or below the minor, severe, or critical alarm threshold, the system issues an alarm to affected service modules or processes.
The system monitors only the amount of free low-memory space. You can use the display memory command to display memory usage information.
If a memory alarm occurs, delete unused configuration items or disable some features to increase the free memory space. Because the memory space is insufficient, some configuration items might not be able to be deleted.
For more information about the thresholds, see Fundamentals Configuration Guide.

Usage guidelines
Password recovery capability controls console user access to the device configuration and SDRAM from BootWare menus.
If password recovery capability is enabled, a console user can access the device configuration without authentication to configure new passwords.
If password recovery capability is disabled, console users must restore the factory-default configuration before they can configure new passwords. Restoring the factory-default configuration deletes the next-startup configuration files.
To enhance system security, disable password recovery capability.
To access the device configuration without authentication, you must connect to the master device and access the BootWare menu while the master device is starting up.
Availability of BootWare menu options depends on the password recovery capability setting. For more information, see the release notes.

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.
If the IRF fabric has only one member device, rebooting the member device reboots the entire IRF fabric. If the IRF fabric has a subordinate member and the member is operating correctly, rebooting the master triggers a master/subordinate switchover.
To ensure correct operation of the IRF fabric and member devices, do not trigger a switchover by rebooting the master if no subordinate member devices are in Stable state. To view the status of subordinate member devices, execute the display system stable state command.

Parameters
interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. To disable port status detection, set this argument to 0.
Usage guidelines
The device starts a port status detection timer when a port is shut down by a protocol. Once the timer expires, the device brings up the port so the port status reflects the port's physical status.
If you change the timer setting during port detection, the device compares the new setting (T1) with the time that elapsed since the port was shut down (T).
If T < T1, the port will be brought up after T1 – T seconds.
If T ≥ T1, the port is brought up immediately.
For example, the timer setting is 30 seconds. If you change it to 10 seconds 2 seconds after the port is shut down, the port will come up 8 seconds later. If you change the timer setting to 2 seconds 10 seconds after the port is shut down, the port comes up immediately.

Parameters
slot slot-number: Specifies an IRF member device by its member ID.
hotspot: Configures temperature alarm thresholds for hotspot sensors. A hotspot sensor is typically located near a high-heat chip to monitor the chip temperature.
sensor-number: Specifies a sensor by its number. To view the value range, enter a question mark (?) in the place of this argument.
lowlimit: Specifies the low-temperature threshold in Celsius degrees. The value range varies by temperature sensor. To view the value range, enter a question mark (?) in the place of this argument.
warninglimit: Specifies the high-temperature warning threshold in Celsius degrees. This threshold must be greater than the low-temperature threshold. To view the value range, enter a question mark (?) in the place of this argument.
alarmlimit: Specifies the high-temperature alarming threshold in Celsius degrees. This threshold must be greater than the warning threshold. To view the value range, enter a question mark (?) in the place of this argument.
Usage guidelines
When the device temperature drops below the low-temperature threshold or reaches the high-temperature warning or alarming threshold, the device performs the following operations:
· Sends log messages and traps.
· Sets LEDs on the device panel.
Examples
# Set temperature alarm thresholds for hotspot sensor 1 in a slot.
<Sysname> system-view
[Sysname] temperature-limit slot 1 hotspot 1 -10 50 60
