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 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

# Display the historical CPU usage statistics.

Default

The port status detection timer setting is 30 seconds.

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.

Views

System view

Predefined user roles

network-admin

Parameters

timeout: Specify the handshake timeout time between an MPU and an interface module, in the range of 10 to 55 seconds.

Usage guidelines

After starting up, an interface module will actively register with an MPU so that it can be managed by the MPU. During device operation, the MPU will periodically send handshake packets to the interface to identify whether the interface module is operating correctly. If the interface module does not reply to the MPU before the specified timeout time expires, the MPU considers the interface module to be faulty and will restart the interface module.

In some scenarios with handshake timeout requirements, you can execute this command to specify a handshake timeout time as needed to identify faulty interfaces as soon as possible. For example, some scenarios might require a short traffic interruption due to card restart.

Examples

# Set the handshake timeout time to 40 seconds between the MPU and an interface module.

Parameters

optical-channel-number: Specifies an optical channel by its channel number, which is fixed at 1.

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

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

Usage guidelines

This command is available only for the QSFPDD-400G-ZR transceiver module.

Before executing this command, use reference frequency 193100000 MHz and the specified operating frequency grid to calculate an operating frequency value as follows:

The operating frequency of an optical channel = 193100000 MHz ± the operating frequency grid × n, where n represents an integer.

If the operating frequency value is calculated incorrectly, the configuration fails.

If you do not specify the grid grid-value option, you can use any supported value for the grid-value argument to calculate the operating frequency value.

If you specify the grid grid-value option, you must use the specified value for the grid-value argument to calculate the operating frequency value. If you fail to do so, the configuration fails.
