See ‘aws help’ for descriptions of global parameters.


--cache-subnet-group-name <value>

[--subnet-ids <value>]

[--cli-auto-prompt <value>]


--cache-subnet-group-name (string)

The name for the cache subnet group. This value is stored as a lowercase string.

Constraints: Must contain no more than 255 alphanumeric characters or hyphens.

Example: mysubnetgroup

--cache-subnet-group-description (string)

A description of the cache subnet group.

--subnet-ids (list)

The EC2 subnet IDs for the cache subnet group.



"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 cache subnet group

The following modify-cache-subnet-group example modifies the specified cache subnet group.

aws elasticache modify-cache-subnet-group \
    --cache-subnet-group-name kxkxk \

    "CacheSubnetGroup": {
        "CacheSubnetGroupName": "kxkxk",
        "CacheSubnetGroupDescription": "mygroup",
        "VpcId": "vpc-xxxxcdb",
        "Subnets": [
                "SubnetIdentifier": "subnet-xxxxbff",
                "SubnetAvailabilityZone": {
                    "Name": "us-west-2a"
