|
|
Setup:
|
|
|
|
TRex host VPP host

How to use TRex:
|
|
1) Copy configuration file to /etc/trex_cfg.yaml or use --cfg option in next step
|
|
2) Start TRex as a server 'sudo ./t-rex-64 -i'
|
|
3) Connect with console './trex-console'
|
|
4) Resolve destination addresses 'reset ; service ; arp ; service --off'
|
|
5) Start traffic to open sessions in2out 'start -f stl/nat_10ks.py -m 10mbps -p 1' or out2in 'start -f stl/nat_out2in_10ks.py -m 10mbps -p 0'
|
|
6) After all sessions are opened update stream rate to 100% 'update -a -m 100%'
|
|
7) Show dynamic statistic 'tui'
|
|
8) Exit dynamic statistic 'q'
|
|
9) Stop traffic 'stop -a'
|
|
10) Sessions per second (slowpath) test 'reset ; service ; arp ; service --off; start -f stl/nat_ses_open.py -m 100% -p 1 -d 1' and 'show nat44' in VPP CLI to see number of opened sessions
|
|
|
|
VPP config files:
|
|
in2out testing nat_dynamic
|
|
for out2in testing generate config using 'nat_static_gen_cfg.py N'
