[Praveen Rai]

Hi Folks,

I am very new to traffic Generator world. Today I download TRex Docker version I read the documentation available on TRex portal but not much useful documentation available on the website. I follow steps mentioned over there but I am only able to see 1 interface in my docker but I added 3 interfaces to my docker Unit.

getting so many error.

The docker image intended for tutorials.

We have a startup script that creates two interfaces (veth0 and veth1) in loopback for making traffic command works.

You can create other interface if you want and change the configuration file accordingly

I suggest to keep this configuration and learn the basic first using the manuals

Thanks,

Hanoh

Thanks, Hanoh for a response.

Suppose I have topology like this :--

                                 (eth1) TRex(eth2)_____

                                     |                                  |

                                     |                                  |

                                     |__(eth0)DUT(eth1)__|

                                         

so int his case how default config of TRex works with ports veth0 & veth1. as in my topology, TRex connected with DUT on eth1 & eth2 port respectively.

as per my understanding, I have to change default config to match these 2 interfaces. 

Sorry but in your docker TRex documentation section not much discussed or written on this .how to use docker version.

please clear my doubts if possible.

Try reading the manual, configuration file descriptions is there.
