Understanding the T-Rex output

[sukeerthi bj]

Hi,

I am initiating T-Rex with following command:

sudo ./t-rex-64 --cfg /etc/trex_cfg_lsn.yaml -f cap2/lsn_traffic.yaml -c 1  -l 1000 -d 10 -m 30  --learn-mode 1

And following is output:

We see multiple global stats output.Why so much time this output comes.How much traffic is the command triggering with following as traffic file:

- duration : 0.1

          distribution : "seq"
          clients_start : "16.0.0.1"
          clients_end   : "16.0.0.1"

          udp_aging      : 0
