[ aws . network-firewall ]

associate-subnets

Description

Associates the specified subnets in the Amazon VPC to the firewall. You can specify one subnet for each of the Availability Zones that the VPC spans.

This request creates an Network Firewall firewall endpoint in each of the subnets. To enable the firewall's protections, you must also modify the VPC's route tables for each subnet's Availability Zone, to redirect the traffic that's coming into and going out of the zone through the firewall endpoint.

Options

--update-token (string)

An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.

To make an unconditional change to the firewall, omit the token in your update request. Without the token, Network Firewall performs your updates regardless of whether the firewall has changed since you last retrieved it.

To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException . If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.

--firewall-arn (string)

The Amazon Resource Name (ARN) of the firewall.

You must specify the ARN or the name, and you can specify both.

--firewall-name (string)

The descriptive name of the firewall. You can't change the name of a firewall after you create it.

You must specify the ARN or the name, and you can specify both.

--subnet-mappings (list)

The IDs of the subnets that you want to associate with the firewall.

(structure)

The ID for a subnet that you want to associate with the firewall. This is used with CreateFirewall and AssociateSubnets . Network Firewall creates an instance of the associated firewall in each subnet that you specify, to filter traffic in the subnet's Availability Zone.

SubnetId -> (string)

The unique identifier for the subnet.

IPAddressType -> (string)

The subnet's IP address type. You can't change the IP address type after you create the subnet.

Shorthand Syntax:

SubnetId=string,IPAddressType=string ...

JSON Syntax:

[
  {
    "SubnetId": "string",
    "IPAddressType": "DUALSTACK"|"IPV4"|"IPV6"
  }
  ...
]

--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.

Output

FirewallArn -> (string)

The Amazon Resource Name (ARN) of the firewall.

FirewallName -> (string)

The descriptive name of the firewall. You can't change the name of a firewall after you create it.

SubnetMappings -> (list)

The IDs of the subnets that are associated with the firewall.

(structure)

The ID for a subnet that you want to associate with the firewall. This is used with CreateFirewall and AssociateSubnets . Network Firewall creates an instance of the associated firewall in each subnet that you specify, to filter traffic in the subnet's Availability Zone.

SubnetId -> (string)

The unique identifier for the subnet.

IPAddressType -> (string)

The subnet's IP address type. You can't change the IP address type after you create the subnet.

UpdateToken -> (string)

An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.
