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.

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.

mdc mdc-id: Specifies the MDC to be used for time synchronization. The value range is 1 to 5.

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 configure 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 configure 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.

If you execute this command multiple times, the most recent configuration takes effect.

All MDCs on the device use the same system time. After obtaining the system time from an MDC, the device automatically synchronizes the system time to the other MDCs.

Examples

# Configure the device to use the local UTC time.

If you do not specify any options, this command displays the statistics for all processes in the IRF fabric. (In IRF mode.)

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.

If you do not specify a file name at the "Please input the file name" prompt, the system saves the information to a new file. The file name contains the device name and the time when the file was generated. If the device name contains any one of the following special characters, the system uses an underscore (_) to replace each special characters: forward slashes (/), backward slashes (\), colons (:), asterisks (*), question marks (?), less than signs (<), greater than signs (>), and vertical bars (|). For example, the file name is like flash:/diag_A_B_20160101-000438.tar.gz if the device name is A/B.

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.

This command is not supported on S7502E, S7503E-M, and S7503M-H switches.

Examples

# (In standalone mode.) Display the load modes for MPUs.

<Sysname> display xbar

The configured system HA xbar load mode is BALANCE

The activated system HA xbar load mode is SINGLE

The output shows that the configured load mode is the load-balance mode but the running load mode is the load-single mode.

Usage guidelines

The port-down feature applies to scenarios where two devices (one active and one standby) are used for high availability, for example, a network deployed with VRRP. This feature shuts down all service ports on the active device immediately after both MPUs on the active device are removed or reboot abnormally. The shutdown operation ensures quick service switchover to the standby device.

NOTE:

This feature takes effect only when no available MPU exists.

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.

Availability of BootWare menu options depends on the password recovery capability setting. For more information, see Fundamental Configuration Guide..

Parameters

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual chassis number. (In IRF mode.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. (In IRF mode.)

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.

In standalone mode:

· To reboot the entire device, do not specify the slot number option.

· To reboot a card, specify the slot number.

· To reboot the active MPU, perform the following tasks:

· Identify whether the standby MPU is installed and operating correctly.

· Use the display system stable state command to display system stability and status information.

· If the standby MPU is not installed, the entire device will be rebooted. If the standby MPU is installed and is operating correctly, a switchover will occur.

IMPORTANT:

To ensure correct operation of the system and cards, do not trigger a switchover by rebooting the active MPU if the status of a card is not Stable.

In IRF mode:

· To reboot all IRF member devices and PEXs, do not specify the member ID option.

· To reboot an IRF member device or PEX, specify only the IRF member ID or virtual chassis number.

· To reboot a card or PEX, specify both the IRF member ID and the slot number.

· To reboot the global active MPU, perform the following tasks:

· Identify whether the IRF fabric has global standby MPUs and whether the global standby MPUs are operating correctly.

· Use the display system stable state command to display system stability and status information.

· If the IRF fabric has only one MPU, the IRF fabric will be rebooted. If the IRF fabric has a global standby MPU and the MPU is operating correctly, a switchover will occur.

IMPORTANT:

To ensure correct operation of the IRF fabric and MPUs, do not trigger a switchover by rebooting the global active MPU if the status of a card is not Stable.

Parameters

time: Specifies the reboot time in the hh:mm format. The value range for hh is 0 to 23. The value range for mm is 0 to 59.

date: Specifies the reboot 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:

Device reboot interrupts network services.

When the date argument is not specified, the system uses the following rules to determine the reboot time:

If the reboot time is later than the current time, a reboot occurs at the reboot time of the current day.

If the reboot time is earlier than the current time, a reboot occurs at the reboot time the next day.

The device supports only one device reboot schedule. If you execute both the scheduler reboot delay and scheduler reboot at commands or execute one of the commands multiple times, the most recent configuration takes effect.

For data security, the system does not reboot at the reboot time if a file operation is being performed.

shutdown-interval

Use shutdown-interval to set the port status detection timer.

Use undo shutdown-interval to restore the default.

Syntax

shutdown-interval interval

undo shutdown-interval

Default

The port status detection timer setting is 30 seconds.

Views

System view

Predefined user roles

network-admin

mdc-admin

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.

Examples

# Set the port status detection timer to 100 seconds.

<Sysname> system-view

[Sysname] shutdown-interval 100
