def verifyProtocolSessionsUp2(self, protocolViewName='Protocols Summary', timeout=60):
        """
        Description
            For IxNetwork version >= 8.50.
            Defaults to Protocols Summary to verify all configured protocol sessions. There is no need
            to specify specific protocols to verify.  However, you still have the option to specific
            protocol session to verify.

            Note: This get stats by using /statistics/statview/<id>/data. Prior to 8.50, 
                  get stats uses /statistics/statview/<id>/page, which is deprecated started 8.50.
                  /statistics/statview/<id>/data is more robust.

        Parameter
            protocolViewName: <str>: The protocol view name. 
                              Get this name from API browser or in IxNetwork GUI statistic tabs.
                              Defaults to 'Protocols Summary'
        
            timeout: <int>: The timeout value to declare as failed. Default = 60 seconds.

            'BGP Peer Per Port'
