+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
+
+Functionality:
+1. Verify the API functionality and get server information
