        Description
            Loop through each Topology Group and its enabled Device Groups and verify
            all the created and activated protocols for session up.
            Applies to Ethernet, IPv4 and IPv6.

        Parameters
           timeout: <int>: The timeout value for declaring as failed. Default = 120 seconds.
           silentMode: <bool>: True to not display less on the terminal.  False for debugging purpose.
