M8 Ne8000 Process too high (more than 60%)

Thanks for contacting the Huawei community!

We are checking your question and will provide an answer to you shortly...

Hi, Carcara!

You can run the display cpu-usage command to check the CPU usage process and the module ID.

In addition, the CPU usage reaches 85%. If the value is less than 85%, ignore this parameter.

Hi!!!!

Itś not common to have this high load, here the display cpu-usage. Do you know how can i identify the process that is this high?

Good answer

Hi Dear,

Common Causes of High CPU Usage

A high CPU usage may be caused by:

Attacks

Network flapping (including STP and routing flapping)

Network loop

Flow sampling configuration on the device, consuming a large number of CPU resources

A large number of logs generated on the device, consuming a lot of CPU resources

According to the command you sent, the task with the highest cpu consumption is "system"

Table 1-1 Common tasks with high CPU usages and solutions

Task Name	Description	Reason for High CPU Usage	Solution
SYSTEM	System management	A large number of protocol packets are processed.	Check whether a network attack occurs.

Please access the following link, and follow the procedures described to know if your network is under attack.

i hope it help ful!

It's strange because it's permanent, so it's not a attack. Maybe the flow sampling but it was almost the same way at the beggining of the migration.

What could you say to me about this log:

display system os-process slot 9

Info: This operation needs several seconds.
Info: Operating, please wait for a moment........done.

This monitor thing, i couldn't find what it´s related.
