 ** [Marker](#API_DescribeReplicationSubnetGroups_RequestSyntax) **   <a name="DMS-DescribeReplicationSubnetGroups-request-Marker"></a>
 An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by `MaxRecords`.   
Type: String  
Required: No

 ** [MaxRecords](#API_DescribeReplicationSubnetGroups_RequestSyntax) **   <a name="DMS-DescribeReplicationSubnetGroups-request-MaxRecords"></a>
