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 Command Reference.

slot slot-number: Specifies a device by its ID, which is fixed at 1.

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

# Display the historical CPU usage statistics.

slot slot-number: Specifies a device by its ID, which is fixed at 1.

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.

You can use the display memory command to display memory usage information.

The early warning feature warns you of an approaching insufficient-memory condition.

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 hardware resource management in System Management Configuration Guide.

The system will restart if one of the following conditions is met:

· After a critical alarm occurs, the remaining free-memory value has been smaller than the critical alarm threshold for 30 seconds.

· The interval between two consecutive critical alarms is shorter than 30 seconds.

· The critical alarm has occurred three times within three minutes.

· After a critical alarm occurs, the system will periodically sample free memory space and predict if the free memory space will be exhausted within 30 seconds. If the prediction result indicates that the free memory space will be exhausted within 30 seconds, the system will restart.

Once the free memory space reaches the minor, severe, or critical alarm threshold, the device will display the current memory usage information when you log in to the device through console or Telnet login, or execute every command.

The sending periods of memory alarm notifications are as follows:

· If the free memory space has consistently exceeded the minor threshold for 12 hours, a minor alarm notification is sent.

· If the free memory space has consistently exceeded the severe threshold for 3 hours, a severe alarm notification is sent.

· If the free memory space has consistently exceeded the critical threshold for 1 hour, a critical alarm notification is sent.

Views

System view

Predefined user roles

network-admin

Parameters

interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. The value of 0 indicates that port status detection is not automatically performed, and you need to execute the undo shutdown command to restore the port status manually.

Usage guidelines

On a network enabled with loop detection or STP, the device starts a port status detection timer when a port is shut down by a protocol. If the port has been in down state before the timer expires, the device will set the port status to 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.

grid grid-value: Specifies the frequency grid for the transceiver optical channel. The value for the grid-value argument varies by transceiver module model. Valid values typically include the grid-value argument include 3125 MHz, 6250 MHz, 12500 MHz, 25000 MHz, 33000 MHz, 50000 MHz, 75000 MHz, and 100000 MHz. To view the grid values supported by a transceiver module, enter a question mark (?) in the place of the grid-value argument.

Usage guidelines

Only the QSFPDD-400G-ZR transceiver module supports this command

Before executing this command, calculate the frequency for a transceiver optical channel based on the grid and the reference frequency of 193100000 MHz. If the frequency is calculated incorrectly, the configuration by this command will fail. To calculate the frequency for a transceiver optical channel:

Frequency for a transceiver optical channel = 193100000 MHz ± Frequency grid for a transceiver optical channel × n. The value for n is an integer.

If the grid grid-value option is not configured, you can use any supported frequency grid value to calculate the frequency for a transceiver optical channel.

If the grid grid-value option is configured, you must use the specified grid value to calculate the frequency for a transceiver optical channel. If you fail to do so, the system will fail to set the frequency.

Parameters

power-value: Specifies the high RX power threshold in dBm, accurate to 0.01 dBm. The value range for the power-value argument varies by transceiver module model.

Usage guidelines

Operating mechanism

You can execute the transceiver rx-power high-threshold command to configure the high RX power threshold for a transceiver module between the default high early-warning threshold and high alarm threshold. If the RX power of a transceiver module exceeds the user-defined threshold, the system generates an alarm message. For example, if the default high threshold range for a transceiver module is 3.00 to 5.00 dBm, you can set the high TX power threshold to 4.40 dBm.

To verify the alarm thresholds for a transceiver module, execute the display transceiver diagnosis command.

Restrictions and guidelines

This command is available only for the SFP, QSFP, QSFPDD, QSFP56, and DSFP transceiver modules that support digital diagnosis and is not available for the 400G ZR, 400G ZR+, or fiber-to-copper transceiver modules.

Parameters

power-value: Specifies the RX power change threshold in dBm, accurate to 0.01 dBm. The value range is 0 to 48.

Usage guidelines

Application scenarios

This command enables the device to monitor significant RX power changes on transceiver modules and generate alarm messages in time.

Operating mechanism

The device sets the initial RX optical power as the baseline for a transceiver module after the transceiver module starts up and operates correctly for the first time. After you execute the transceiver rx-power change-threshold command, the system checks the RX optical power of a transceiver module periodically. If an RX optical power change exceeds the user-defined threshold compared to the baseline, the system identifies it as a significant change and generates an alarm. For example, the RX power change threshold is set to 20.00 dBm, the initial RX optical power after the link starts up and operates correctly is –15.00 dBm. Then, if the RX optical power decreases to –36.00 dBm or increases to 6.00 dBm, an alarm occurs.

Restrictions and guidelines

If a transceiver module has multiple lanes, the configuration takes effect for all lanes.
