Trex: Issue running Traffic out designated ports

I'm having an issues running traffic out of the specified ports in the configuration yaml file.  I am trying to run out of the interfaces as such:

cisco@sre-ubjh2:/opt/trex/v2.91$ cat /etc/trex_cfg_mac.yaml
### Config file generated by dpdk_setup_ports.py ###

- version: 2
interfaces: ['13:00.0', '04:00.0']
port_info:
- dest_mac: 00:50:56:a8:d6:c0 # TS 1 - 3
src_mac: 00:50:56:a8:e3:3b
- dest_mac: 00:50:56:a8:e3:3b
src_mac: 00:50:56:a8:d6:c0

platform:
master_thread_id: 0
latency_thread_id: 1
dual_if:
- socket: 0
threads: [2]

- socket: 0
threads: [3]

 

In that file you can see I have specified the correct masks and you can see that output from the ports here:

 

cisco@sre-ubjh2:/opt/trex/v2.91$ sudo ./dpdk_setup_ports.py -t

When I run traffic the Total-Tx always matches the drop-rate as shown here:

*** TRex is shutting down - cause: 'CTRL + C detected'

 

Is there something that sticks out in my configuration file that is causing the traffic not to go out the correct interface?
