cpu cpu-number: Displays the historical CPU usage statistics. The cpu-number argument must be 0.

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.

· Consecutive pound signs (#) indicate the CPU usage at a specific time. 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 for the entire system.

Usage guidelines

Password recovery capability controls console user access to the device configuration and SDRAM from Boot ROM 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 Boot ROM menu options varies by 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 this option, the command reboots all member devices.

force: Reboots the device immediately without performing any software check. If this keyword is not specified, the system first checks whether the reboot might result in data loss or a system failure. For example, the system checks 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 device reboot might interrupt network services.

· If the main startup software images are corrupted 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.

Use the force keyword only when you cannot reboot the device without using it.

Examples

# Reboot the device when no configuration change has occurred since the last time you saved the running configuration.

<Sysname> reboot

Start to check configuration with next startup configuration file, please wait.........DONE!

This command will reboot the device. Continue? [Y/N]:y

shutdown-interval

Use shutdown-interval to set the detection timer.

Use undo shutdown-interval to restore the default.

Syntax

shutdown-interval time

undo shutdown-interval

Default

The detection interval is 30 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

time: Specifies a detection timer in the range of 0 to 300 seconds. Setting it to 0 disables the detection function.

Usage guidelines

The device starts a 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 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, if you change the timer from 30 seconds to 10 seconds two seconds after the port is shut down, the port will come up 8 seconds later. If you change the timer from 30 seconds to 2 seconds ten seconds after the port is shut down, the port comes up immediately.

Examples

# Set the detection timer to 100 seconds.

<Sysname> system-view

[Sysname] shutdown-interval 100

2: Sets the table capacity mode to 2.

3: Sets the table capacity mode to 3.

4: Sets the table capacity mode to 4.

5: Sets the table capacity mode to 5.

Usage guidelines

The switch supports multiple table capacity modes. The capacities of the MAC address table, ARP/ND table, and routing table vary by the following items:

· Table capacity mode.

· Whether the switch-routing-mode ipv6-128 command is configured. For more information about the switch-routing-mode ipv6-128 command, see Layer 3—IP Routing Command Reference.

For table capacities in different scenarios, see Fundamentals Configuration Guide.

Mode 4 and the switch-routing-mode ipv6-128 command are mutually exclusive.

Mode 5 and the switch-routing-mode ipv6-128 command are mutually exclusive.

This setting takes effect after a reboot. Before rebooting the switch, make sure you know the possible impact on the network.
