describeDBSubnetGroups method
Returns a list of DBSubnetGroup descriptions. If a
DBSubnetGroupName is specified, the list will contain only
the descriptions of the specified DBSubnetGroup.
May throw DBSubnetGroupNotFoundFault.
Parameter dBSubnetGroupName :
The name of the subnet group to return details for.
Parameter filters :
This parameter is not currently supported.
Parameter marker :
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.
Parameter maxRecords :
The maximum number of records to include in the response. If more records
exist than the specified MaxRecords value, a pagination token
(marker) is included in the response so that the remaining results can be
retrieved.
Default: 100
Constraints: Minimum 20, maximum 100.
