Centos 7 network throttling

Post by majster-b » 2021/12/03 08:21:01

Hello Everyone,

I would like to simulate a very slow sftp server and use NetEm to limit the connection quality. The machine has two interfaces - ens192 and ens224.
The problem is that if you apply the following rule for an ens192...

Code: Select all

sudo tc qdisc add dev ens192 root netem corrupt 50%
interface, throttling works for both interfaces. If he applies the rule for ens224

Code: Select all

sudo tc qdisc add dev ens224 root netem corrupt 50%
the rule does not work at all. Anyone met with this?

Spec:
Virtualization: vmware
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-1160.45.1.el7.x86_64
Architecture: x86-64

Thank you for any help.
Majster
