TRex and VPP

[linxing...@gmail.com]

Hi all,
I'm trying to use TRex to test VPP performance. I installed TRex and VPP on the same VM. How can I use TRex to send packages to VPP?

Thanks!

Hi Xingchen, 

It is a bit more difficult to run both VPP and TRex on the same machine. (DPDK init)

It is not clear if you want to use phy interfaces or not.

I would start by running each of them separately on the same machine (phy or virt interfaces)

then look into the thread (on this forum) for how to run L2FW and TRex on the same machine for the detail how to do them both

thanks,

Hanoh

Hi Hanoh,


 I installed them on VMware and binded some virtual Ethernet adapters to igb_uio.ko (dpdk). When configuring the trex_cfg.yaml file, I used two of them. Is the one used as server port and the other as client port?
 And then how can I configure the interfaces by VPP in order to make the packages sent to VPP?


Thanks!

Is that case try to run TRex in a separate VM first with two VMXNET3 interfaces .

not sure about the performance as vSwitch will limit you

If I run TRex in a separate VM first, and run VPP in the other separate VM, is there some methods to connect the interfaces between the two VMs?
I'm new here and don't konw much about it. Thanks a lot for your patience!




Thanks,

Hi,

You have several options:

1. Connect virtual interfaces via vSwitch or bridge.
2. Use VFs of real NICs (SR-IOV)
3. Give real NICs to VMs and connect them via loopback cable.

Thanks,

Yaroslav.
