Returns one or more cluster subnet group objects, which contain metadata about your cluster subnet groups. By default, this operation returns information about all cluster subnet groups that are defined in you AWS account.
If you specify both tag keys and tag values in the same request, Amazon Redshift returns all subnet groups that match any combination of the specified keys and values. For example, if you have owner and environment for tag keys, and admin and test for tag values, all subnet groups that have any combination of those values are returned.
If both tag keys and values are omitted from the request, subnet groups are returned regardless of whether they have tag keys or values associated with them.
/// The cluster subnet group name does not refer to an existing cluster subnet group.

/// The tag is invalid.
