Hello, I am trying to run the basic http_simple.yaml file and am getting output with tx_ok and rx_ok packet counters going up, but the bytes counter is not going up. The setup is two port with ports 0 and 1.

First off, here is the dpdk port output:

tester@trex:~/trex/v2.00$ ./dpdk_setup_ports.py --s

Network devices using DPDK-compatible driver

============================================

0000:00:07.0 '82540EM Gigabit Ethernet Controller' drv=igb_uio unused=

0000:00:08.0 '82540EM Gigabit Ethernet Controller' drv=igb_uio unused=

Network devices using kernel driver

===================================

0000:00:03.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio

Other network devices

=====================

<none>

Next is the trex_cfg.yaml file using these ports:

tester@trex:~$ more /etc/trex_cfg.yaml

- port_limit : 2 # this option can limit the number of port of the platform

version : 2

interfaces : ["00:07.0","00:08.0"] #the interfaces using ./dpdk_setup_ports.py -s

port_info : # set eh mac addr

- dest_mac : [0x52,0x54,0x00,0xf4,0x88,0xc3] # router mac addr should be taken from router

src_mac : [0x52,0x54,0x00,0x1d,0x83,0x37] # source mac-addr - taken from ifconfig

- dest_mac : [0x52,0x54,0x00,0xda,0x6f,0xc8] # router mac addr taken from router

src_mac : [0x52,0x54,0x00,0xf1,0xf9,0x4b] #source mac-addr taken from ifconfig

Next is the http_simple.yaml . No changes made except to the client and server IP ranges.

Finally, verbose mode enabled output :

The test is for a duration of 10 seconds and no latency, and output is pasted below:
