 For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

 ** Marker **   
An optional parameter that specifies the starting point to return a set of response records. When the results of a [DescribeReservedNodes](#API_DescribeReservedNodes) request exceed the value specified in `MaxRecords`, AWS returns a value in the `Marker` field of the response. You can retrieve the next set of response records by providing the returned marker value in the `Marker` parameter and retrying the request.   
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: No

 ** MaxRecords **   
The maximum number of response records to return in each call. If the number of remaining response records exceeds the specified `MaxRecords` value, a value is returned in a `marker` field of the response. You can retrieve the next set of records by retrying the command with the returned marker value.   
Default: `100`   
Constraints: minimum 20, maximum 100.  
Type: Integer  
Required: No

 ** ReservedNodeId **   
Identifier for the node reservation.

## Response Elements
<a name="API_DescribeReservedNodes_ResponseElements"></a>

The following elements are returned by the service.

 ** Marker **

If the `Marker` field is empty, all response records have been retrieved for the request.
