Options

--subnet-id (string)

The ID of the subnet.

--cidr (string)

The IPv4 or IPV6 CIDR range to reserve.

--reservation-type (string)

The type of reservation. The reservation type determines how the reserved IP addresses are assigned to resources.

  • prefix - Amazon Web Services assigns the reserved IP addresses to network interfaces.
  • explicit - You assign the reserved IP addresses to network interfaces.

Possible values:

  • prefix
  • explicit

--description (string)

The description to assign to the subnet CIDR reservation.

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--tag-specifications (list)

The tags to assign to the subnet CIDR reservation.

(structure)

The tags to apply to a resource when the resource is being created. When you specify a tag, you must specify the resource type to tag, otherwise the request will fail.

Note

The Valid Values lists all the resource types that can be tagged. However, the action you're using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you're using, you'll get an error.

ResourceType -> (string)

The type of resource to tag on creation.

Tags -> (list)

The tags to apply to the resource.

(structure)

Describes a tag.

Key -> (string)

The key of the tag.

Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with aws: .

Value -> (string)

The value of the tag.

Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To create a subnet CIDR reservation

The following create-subnet-cidr-reservation example creates a subnet CIDR reservation for the specified subnet and CIDR range.

aws ec2 create-subnet-cidr-reservation \
    --subnet-id subnet-03c51e2eEXAMPLE \
    --reservation-type prefix \
    --cidr 10.1.0.20/26

Output:

{
    "SubnetCidrReservation": {
        "SubnetCidrReservationId": "scr-044f977c4eEXAMPLE",
        "SubnetId": "subnet-03c51e2e6cEXAMPLE",
        "Cidr": "10.1.0.16/28",
        "ReservationType": "prefix",
        "OwnerId": "123456789012"
    }
}
