          Args:
              port_int (str): port-channel number (1, 2, 3, etc).
              callback (function): A function executed upon completion of the
                   method.  The only parameter passed to `callback` will be the
                   ``ElementTree`` `config`.
  
          Returns:
              Return value of `callback`.
  
          Raises:
              KeyError: if `port_int` is not passed.
              ValueError: if `port_int` is invalid.
  
          Examples:

              >>> switches = ['10.24.39.211', '10.24.39.203']
              >>> auth = ('admin', 'password')
