Key
   -ComputerName
       The Domain Name System (DNS) name or IP address of the target computer.

   -CommonTCPPort
       The common service TCP port number.
       Accepted values: SMB  HTTP  RDP  WINRM

   -ConstrainInterface 
       The interface constraint to use for route diagnostics.

   -ConstrainSourceAddress 
       The source address constraint to use for route diagnostics.

   -DiagnoseRouting
       Indicates that route diagnostics runs to output the route and source address selection information for the remote host.

   -Hops
       The number of hops to traverse in a trace route command.


   -InformationLevel 
       The information level.
         Accepted values: 
         • Detailed
         • Quiet    If you set this parameter to Quiet, the cmdlet returns basic information.
