anchor.diff:  of IPs in all groups in the client config file together, must cover the entire range of client IPs
   from the traffic profile file.
   
  -MACs will be allocated incrementally, with a wrap around after count addresses.
  +MACs will be allocated incrementally, with a wrap around after ``count'' addresses.
   
   e.g.
   
  
positive.code: will exit with an error message. +
  If client config file is given, the ``dest_mac'' and ``default_gw'' parameters from the platform config
  file are ignored.
  
  
  [NOTE]
  
negative.code: * 48.x.x.x -> 16.0.0.2  - dst_mac(from responder) : "00:00:00:02:00:01" , vlan:200
  
  and so on. +
   +
  This means that the MAC addresses of DUTs must be changed to be sequential. Other option is to
  specify instead of ``dst_mac'', ip address, using ``next_hop''. +
  For example, config file first group will look like:
  
  [source,bash]
  ----
  -    ip_start  : 16.0.0.1
       ip_end    : 16.0.0.204
