+"""This script uses T-REX stateless API to drive t-rex instance.
+
+Requirements:
+- T-REX: https://github.com/cisco-system-traffic-generator/trex-core 
+ - compiled and running T-REX process (eg. ./t-rex-64 -i -c 4)
+ - trex_stl_lib.api library
+- Script must be executed on a node with T-REX instance
+- 2 interfaces must be configured in configuretion file /etc/trex_cfg.yaml
+
+##################### Example of /etc/trex_cfg.yaml ##########################
+- port_limit      : 2 # numbers of ports to use
+  version         : 2
+  interfaces      : ["84:00.0","84:00.1"] # PCI address of interfaces
+  port_info       :  # set eth mac addr 
+          - dest_mac        :   [0x90,0xe2,0xba,0x1f,0x97,0xd5]  # port 0
+            src_mac         :   [0x90,0xe2,0xba,0x1f,0x97,0xd4]
+          - dest_mac        :   [0x90,0xe2,0xba,0x1f,0x97,0xd4]  # port 1

+##############################################################################
+
+Functionality:
+1. Configure traffic on running T-REX instance
+2. Clear statistics on all ports
+3. Ctart traffic with specified duration
+4. Print statistics to stdout
