Modifies the settings for the specified replication subnet group.

See ‘aws help’ for descriptions of global parameters.


--replication-subnet-group-identifier <value>
[--replication-subnet-group-description <value>]
--subnet-ids <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--replication-subnet-group-identifier (string)

The name of the replication instance subnet group.

--replication-subnet-group-description (string)

A description for the replication instance subnet group.

--subnet-ids (list)

A list of subnet IDs.



"string" "string" ...

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To modify a subnet group

The following modify-replication-subnet-group example changes the lists of subnets associated with a subnet group.

aws dms modify-replication-subnet-group \
    --replication-subnet-group-identifier my-subnet-group \
    --subnet-id subnet-da327bf6 subnet-bac383e0


    "ReplicationSubnetGroup": {
        "ReplicationSubnetGroupIdentifier": "my-subnet-group",
        "ReplicationSubnetGroupDescription": "my subnet group",
        "VpcId": "vpc-136a4c6a",
        "SubnetGroupStatus": "Complete",
        "Subnets": [
                "SubnetIdentifier": "subnet-da327bf6",
                "SubnetAvailabilityZone": {
                    "Name": "us-east-1a"
                "SubnetStatus": "Active"
                "SubnetIdentifier": "subnet-bac383e0",
                "SubnetAvailabilityZone": {

                "SubnetStatus": "Active"
