# DescribeDefaultClusterParameters
<a name="API_DescribeDefaultClusterParameters"></a>

Returns a list of parameter settings for the specified parameter group family.

 For more information about parameters and parameter groups, go to [Amazon Redshift Parameter Groups](https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-parameter-groups.html) in the *Amazon Redshift Cluster Management Guide*.

## Request Parameters
<a name="API_DescribeDefaultClusterParameters_RequestParameters"></a>

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

 ** ParameterGroupFamily **   
The name of the cluster parameter group family.  
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: Yes

 ** Marker **   
An optional parameter that specifies the starting point to return a set of response records. When the results of a [DescribeDefaultClusterParameters](#API_DescribeDefaultClusterParameters) 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

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

The following element is returned by the service.

 ** DefaultClusterParameters **   
Describes the default cluster parameters for a parameter group family.  
Type: [DefaultClusterParameters](API_DefaultClusterParameters.md) object

## Errors
