network-operator

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 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 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.

Parameters

ratio: Specifies free-memory thresholds in percentage. If you do not specify this keyword, the command sets free-memory thresholds in MB.

minor minor-value: Specifies the minor alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the minor-value argument. Setting this threshold to 0 disables the minor alarm feature.

severe severe-value: Specifies the severe alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the severe-value argument. Setting this threshold to 0 disables the severe alarm feature.

critical critical-value: Specifies the critical alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the critical-value argument. Setting this threshold to 0 disables the critical alarm feature.

normal normal-value: Specifies the normal state threshold. To view the value range for this threshold, enter a question mark (?) in the place of the normal-value argument.

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command sets free-memory thresholds for the master device.

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.

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.

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

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.

Parameters

optical-channel-number: Specifies an optical channel by its number. The value is 1.

frequency-value: Specifies an operating frequency for the transceiver optical channel, in the range of 191300000 to 196100000 MHz.

grid grid-value: Specifies the frequency grid for the transceiver optical channel. The value for the grid-value argument varies by transceiver module model. The typical values for 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.

Examples

# Set the frequency for optical channel 1 of the transceiver module in FourHundredGigE 1/0/1.

Parameters

optical-channel-number: Specifies an optical channel by its number. The value is 1.

power-value: Specifies the transmit power, in dBm, with accuracy to 0.01. The value range varies by transceiver module model.

Usage guidelines

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

This device does not save this command setting to the configuration file but to the transceiver internal register. If the transceiver module is hot swapped or reset, you must re-execute this command for it to take effect.

Examples

Usage guidelines

A transceiver module generally operates in high power mode. If the transceiver module does not work for a long time, you can switch the transceiver module to low power mode to reduce power consumption. In low power mode, the transceiver module does not transmit signals.

The power mode setting is saved in a register on the transceiver module. It is not saved to the configuration file.
