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 the slot number of the device, 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.

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.
