set-subnets

Description

Enables the Availability Zones for the specified public subnets for the specified Application Load Balancer, Network Load Balancer or Gateway Load Balancer. The specified subnets replace the previously enabled subnets.

When you specify subnets for a Network Load Balancer, or Gateway Load Balancer you must include all subnets that were enabled previously, with their existing configurations, plus any additional subnets.

Options

--load-balancer-arn (string)

The Amazon Resource Name (ARN) of the load balancer.

--subnets (list)

The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

[Application Load Balancers] You must specify subnets from at least two Availability Zones.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Network Load Balancers and Gateway Load Balancers] You can specify subnets from one or more Availability Zones.

(string)

"string" "string" ...

--subnet-mappings (list)

The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

[Application Load Balancers] You must specify subnets from at least two Availability Zones. You can't specify Elastic IP addresses for your subnets.

[Application Load Balancers on Outposts] You must specify one Outpost subnet.

[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

[Network Load Balancers] You can specify subnets from one or more Availability Zones. You can specify one Elastic IP address per subnet if you need static IP addresses for your internet-facing load balancer. For internal load balancers, you can specify one private IP address per subnet from the IPv4 range of the subnet. For internet-facing load balancer, you can specify one IPv6 address per subnet.

[Gateway Load Balancers] You can specify subnets from one or more Availability Zones.

(structure)

Information about a subnet mapping.

SubnetId -> (string)

The ID of the subnet.

AllocationId -> (string)

[Network Load Balancers] The allocation ID of the Elastic IP address for an internet-facing load balancer.

PrivateIPv4Address -> (string)

[Network Load Balancers] The private IPv4 address for an internal load balancer.

IPv6Address -> (string)

[Network Load Balancers] The IPv6 address.

SourceNatIpv6Prefix -> (string)

[Network Load Balancers with UDP listeners] The IPv6 prefix to use for source NAT. Specify an IPv6 prefix (/80 netmask) from the subnet CIDR block or auto_assigned to use an IPv6 prefix selected at random from the subnet CIDR block.

Shorthand Syntax:

SubnetId=string,AllocationId=string,PrivateIPv4Address=string,IPv6Address=string,SourceNatIpv6Prefix=string ...

JSON Syntax:

[
  {
    "SubnetId": "string",
    "AllocationId": "string",
    "PrivateIPv4Address": "string",
    "IPv6Address": "string",
    "SourceNatIpv6Prefix": "string"
  }
  ...
]

--ip-address-type (string)

The IP address type.

[Application Load Balancers] The possible values are ipv4 (IPv4 addresses), dualstack (IPv4 and IPv6 addresses), and dualstack-without-public-ipv4 (public IPv6 addresses and private IPv4 and IPv6 addresses).

[Network Load Balancers and Gateway Load Balancers] The possible values are ipv4 (IPv4 addresses) and dualstack (IPv4 and IPv6 addresses).

Possible values:

  • ipv4
  • dualstack
  • dualstack-without-public-ipv4

--enable-prefix-for-ipv6-source-nat (string)

[Network Load Balancers with UDP listeners] Indicates whether to use an IPv6 prefix from each subnet for source NAT. The IP address type must be dualstack . The default value is off .

Possible values:

  • on
  • off

--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.

--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 enable Availability Zones for a load balancer

This example enables the Availability Zone for the specified subnet for the specified load balancer.

Command:

aws elbv2 set-subnets --load-balancer-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188 --subnets subnet-8360a9e7 subnet-b7d581c0

Output:

{
  "AvailabilityZones": [
      {
          "SubnetId": "subnet-8360a9e7",
          "ZoneName": "us-west-2a"
      },
      {
          "SubnetId": "subnet-b7d581c0",
          "ZoneName": "us-west-2b"
