I found the misconfiguration. The DiffServ configuration at the core
router was done for the ingress network interface, therefore the only
packets treated were pings and not mgen or iperf. If the configuration
is done at the egress network interface then it works correctly.

Hello,
I have the following proplem. My DiffServ configuration is working fine
when I do ping, but when I use mgen the packets are not detected at the
core router.
Here is my core router configuration:
#!/bin/bash
