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 a card by its slot number. If you specify a process but do not specify a card, this command displays the statistics for the process on the active MPU. If you do not specify any options, this command displays the statistics for all processes on all cards.

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 tracking is enabled, the system regularly samples CPU usage and saves the samples to a 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

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 any feature parameters, this command displays or saves the operating information for all features and modules.

If you do not specify a file name for the command, 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.

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.

Usage guidelines

This command takes effect only when the hardware-failure-detection forwarding isolate command is configured.

When the hardware-failure-protection aggregation command is configured, the system uses the following rules when it detects a hardware failure on an aggregation group member interface:

· If the undo hardware-failure-protection auto-down command is configured on the member interface and the member interface is the only member in up state in the group, the system does not shut down the interface.

· If the undo hardware-failure-protection auto-down command is configured on the member interface and the member interface is not the only member in up state in the group, the system shuts down the interface.

· If the hardware-failure-protection auto-down command is configured on the member interface, the system shuts down the interface, whether or not the member interface is the only member in up state in the group.

This command does not take effect on a member interface in the following situations:

· Loopback testing is enabled (using the loopback { external | internal } command).

· The interface is forcibly brought up (using the port up-mode command).

· The undo hardware-failure-protection auto-down command is not configured on the interface.

cpu cpu-number: Specifies a CPU by its number.

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.

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.

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] shutdown-interval 100

switch-fabric isolate

Use switch-fabric isolate to isolate a switching fabric module or channel from the data plane.

Use undo switch-fabric isolate to cancel the isolation of a switching fabric module or channel.

Syntax

switch-fabric isolate slot slot-number [ channel channel-number ]

undo switch-fabric isolate slot slot-number [ channel channel-number ]

Default

A switching fabric module is not isolated from the data plane and can forward traffic.

network-admin

Parameters

slot slot-number: Specifies a switching fabric module by its slot number. (In standalone mode.)

channel channel-number: Specifies a data channel by its number. If you do not specify this option, the command isolates the entire switching fabric module.

Usage guidelines

CAUTION:

· Do not isolate the only switching fabric module of the device.

· Use this command only if required. If the device has multiple switching fabric modules, isolating a switching fabric module or channel decreases the forwarding bandwidth and reduces the forwarding performance.

· Do not reboot the device when a switching fabric module is isolated.

This command does not isolate the MPU.

An isolated switching fabric module continues to communicate with the MPU, and can forward traffic immediately after the isolation is canceled. The isolation does not affect protocol packet parsing and protocol calculation on the control plane.

You can use this command to identify whether switching fabric modules can forward traffic correctly.

Before replacing a switching fabric module, isolate the module to prevent packet loss.

To use an isolated switching fabric module or channel, use the undo switch-fabric isolate command to cancel the isolation.

Examples

# Isolate the switching fabric module in slot 10.

<Sysname> system-view

[Sysname] switch-fabric isolate slot 10

The command will isolate the switch fabric from the system. Continue? [Y/N]y

switch-fabric removal-signal-suppression

Use switch-fabric removal-signal-suppression to suppress removal interrupt signals from switching fabric modules.

Use undo switch-fabric removal-signal-suppression to restore the default.

Syntax

switch-fabric removal-signal-suppression

undo switch-fabric removal-signal-suppression

Default

Removal interrupt signals from switching fabric modules are not suppressed.

Views

System view

Predefined user roles

network-admin

Usage guidelines

CAUTION:

Use this command with caution. This command might result in packet loss and service outage.

‌

Typically, removing a switching fabric module triggers one removal interrupt signal. Upon receiving the signal, the system switches traffic on the switching fabric module to other switching fabric modules to ensure service continuity. Upon hardware failure or signal interference, however, removal interrupt signals might be frequently triggered. To prevent the interrupt signals from affecting system operation, you can execute this command to suppress the interrupt signals.

Examples

# Suppress removal interrupt signals from switching fabric modules.

<Sysname> system-view

[Sysname] switch-fabric removal-signal-suppression

switch-linecard isolate

Use switch-linecard isolate to isolate a service card.

Syntax

switch-linecard isolate slot slot-number

Views

System view

Predefined user roles

network-admin

Parameters

slot slot-number: Specifies a service card by its slot number.

Usage guidelines

A service module reboot or device reboot cancels the isolation of the module or all service modules. To continue to isolate a service module after the service module starts up, you must use this command to isolate the module again.

When a service module fails, you can use this command to isolate it to prevent it from affecting traffic forwarding.

To view operating status of service modules, execute the display device command. An isolated service module is in Offline state.

Examples

# Isolate the service card in slot 2.

<Sysname> system-view

[Sysname] switch-linecard isolate slot 2

Parameters

slot slot-number: Specifies a card by its slot number.

hotspot: Configures temperature alarm thresholds for hotspot sensors. A hotspot sensor is typically near the chip that generates a great amount of heat and used to monitor the chip.

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.
