Interface breaks down after TRex is started

[thof...@gmail.com]

Hi,

I am new to TRex and I want to setup an environment for performance testing.

I have an Ubuntu machine running TRex with two interfaces:
* p2p1: 11.1.1.2
* p2p2: 12.1.1.2

Also I have a NFVIS machine running a router (ISRv) with the ip addresses:
* G2: 11.1.1.1
* G3: 12.1.1.1

I have connected the two interfaces of Ubuntu with NFVIS with a cable and I'm able to ping the one machine from the other.

My configuration file for TRex looks as follows:
- port_limit: 2
version: 2
interfaces: ['04:00.0', '04:00.1']
port_info:
- default-gw: 11.1.1.1
ip: 11.1.1.2
- default-gw: 12.1.1.1
ip: 12.1.1.2
platform:
master_thread_id: 0
latency_thread_id: 15
dual_if:
- socket: 0
threads: [1,2,3,4,5,6,7,8,9,10,11,12,13,14]

wheras 04.00.0 is p2p1 and 04.00.1 is p2p2.

Now when I try to run the command:
sudo ./t-rex-64 -f cap2/dns.yaml -c 4 -m 1 -d 10

It always fails with: Failed resolving dest MAC for default gateway:0.0.0.0 on port 0
... and my two interfaces p2p1 and p2p2 are down and I can only bring them up again by rebooting.

Now, I'm wondering why my interfaces are always brought down as soon as I start TRex. I would be grateful for any help or ideas.

Thanks!
Tobias

Hi,

1. default_gw

   
   
2. TRex uses it's own driver for higher speeds.
   To avoid such behavior, use 'p2p1' and 'p2p2' in interfaces list of config file.
   
   
3. You can return them to usual driver with command:
   sudo ./dpdk_setup_ports.py -L
   
   

Thanks,

Yaroslav.
