  **Request Syntax**
  ::

    response = network_interface.describe_attribute(
        DryRun=True|False,
        Attribute='description'|'groupSet'|'sourceDestCheck'|'attachment'|'associatePublicIpAddress'
    )
    
  :type DryRun: boolean
  :param DryRun: 

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is ``DryRunOperation``. Otherwise, it is ``UnauthorizedOperation``.

    

  
  :type Attribute: string
  :param Attribute: 

    The attribute of the network interface. This parameter is required.
