Ethernet-USB converter

[Amir Reza Azmoode]

Hi all,

I have set up TRex on my CentOS laptop to getting familiar with this traffic generator. I also bought an Ethernet-USB converter to have two ports for TRex (this link).
By " ifconfig" or "ip address show" in the Linux terminal, both interfaces are detected.
But when I do "sudo ./dpdk_setup_ports.py  -i ", TRex just detects the built-in laptop NIC.

Is there any way to help TRex to detect Ethernet-USB convertors too?

Hi, 

You can use the linux interface instead of PCI (DPDK)

see here:
