+# password       - root password for TRex machine
+# is_dual        - should the TRex inject with -p ?
+# version_path   - path to the TRex version and executable

+# latency        - rate of latency packets injected by the TRex
+# modes          - list of modes (tagging) of this setup (loopback, virtual etc.)
+# 	  * loopback - Trex works via loopback. Router and TFTP configurations may be skipped.
+#     * virtual  - virtual OS (accept low CPU utilization in tests)

+### Router configuration:
+# hostname       - the router hostname as apears in ______# cli prefix
+# ip_address     - the router's ip that can be used to communicate with
+# image          - the desired imaged wished to be loaded as the router's running config
+# line_password  - router password when access via Telent
+# en_password    - router password when changing to "enable" mode
+# interfaces     - an array of client-server pairs, representing the interfaces configurations of the router
+# configurations - an array of configurations that could possibly loaded into the router during the test. 
+#                  The "clean" configuration is a mandatory configuration the router will load with to run the basic test bench
+
+### TFTP configuration:
+# hostname       - the tftp hostname
+# ip_address     - the tftp's ip address
+# images_path    - the tftp's relative path in which the router's images are located
