[ aws . globalaccelerator ]



Provides a complete mapping from the public accelerator IP address and port to destination EC2 instance IP addresses and ports in the virtual public cloud (VPC) subnet endpoint for a custom routing accelerator. For each subnet endpoint that you add, Global Accelerator creates a new static port mapping for the accelerator. The port mappings don't change after Global Accelerator generates them, so you can retrieve and cache the full mapping on your servers.

If you remove a subnet from your accelerator, Global Accelerator removes (reclaims) the port mappings. If you add a subnet to your accelerator, Global Accelerator creates new port mappings (the existing ones don't change). If you add or remove EC2 instances in your subnet, the port mappings don't change, because the mappings are created when you add the subnet to Global Accelerator.

The mappings also include a flag for each destination denoting which destination IP addresses and ports are allowed or denied traffic.

See also: AWS API Documentation

list-custom-routing-port-mappings is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: PortMappings


--accelerator-arn <value>
[--endpoint-group-arn <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--endpoint-url <value>]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]


--accelerator-arn (string)

The Amazon Resource Name (ARN) of the accelerator to list the custom routing port mappings for.

--endpoint-group-arn (string)

The Amazon Resource Name (ARN) of the endpoint group to list the custom routing port mappings for.

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

--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.



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 .

PortMappings -> (list)

The port mappings for a custom routing accelerator.


Returns the ports and associated IP addresses and ports of Amazon EC2 instances in your virtual private cloud (VPC) subnets. Custom routing is a port mapping protocol in Global Accelerator that statically associates port ranges with VPC subnets, which allows Global Accelerator to route to specific instances and ports within one or more subnets.

AcceleratorPort -> (integer)

The accelerator port.

EndpointGroupArn -> (string)

The Amazon Resource Name (ARN) of the endpoint group.

EndpointId -> (string)

The IP address of the VPC subnet (the subnet ID).

DestinationSocketAddress -> (structure)

The EC2 instance IP address and port number in the virtual private cloud (VPC) subnet.

IpAddress -> (string)

The IP address for the socket address.

Port -> (integer)

The port for the socket address.

Protocols -> (list)

The protocols supported by the endpoint group.


DestinationTrafficState -> (string)

Indicates whether or not a port mapping destination can receive traffic. The value is either ALLOW, if traffic is allowed to the destination, or DENY, if traffic is not allowed to the destination.

NextToken -> (string)

The token for the next set of results. You receive this token from a previous call.
