disassociate-subnet-cidr-block

Description

Disassociates a CIDR block from a subnet. Currently, you can disassociate an IPv6 CIDR block only. You must detach or delete all gateways and resources that are associated with the CIDR block before you can disassociate it.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  disassociate-subnet-cidr-block
--association-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--association-id (string)

The association ID for the CIDR block.

--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.

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 disassociate an IPv6 CIDR block from a subnet

This example disassociates an IPv6 CIDR block from a subnet using the association ID for the CIDR block.

Command:

aws ec2 disassociate-subnet-cidr-block --association-id subnet-cidr-assoc-3aa54053

Output:

{
  "SubnetId": "subnet-5f46ec3b",
  "Ipv6CidrBlockAssociation": {
      "Ipv6CidrBlock": "2001:db8:1234:1a00::/64",
      "AssociationId": "subnet-cidr-assoc-3aa54053",
      "Ipv6CidrBlockState": {
          "State": "disassociating"
      }
  }
}

Output

Ipv6CidrBlockAssociation -> (structure)

Information about the IPv6 CIDR block association.

AssociationId -> (string)

The ID of the association.

Ipv6CidrBlock -> (string)

The IPv6 CIDR block.

Ipv6CidrBlockState -> (structure)

The state of the CIDR block.

State -> (string)

The state of a CIDR block.
