what is netsteam?

it looks well, what is the problem? The sampling, it's quite aggressive, you sample to 1! Note that this might bring some risks, you may overload the CPU.

ip netstream sampler fix-packets 1 inbound
ip netstream sampler fix-packets 1 outbound

The problem is that before huawei I did not have that risk straight.

I always collect all packages. My traffic is low

If the traffic it's low, then it may be okay. I recommend to monitor the CPU for while and also keep in mind to check it in the future if the traffic passing through the system is increasing.

There's something wrong.
Is the number of packages exactly the same all day long?:(

CPU, I will monitore it. tks

What's wrong?
the number of packets may vary based on the traffic characteristics from that day.

In the image has the graphic before the huawei and after.

You can see the difference, after the huawei seems to be limited the number of packages.

The huawei in the graphic is yellow and blue.

The others are other equipment.
