describe-transit-gateways

Description

Describes one or more transit gateways. By default, all transit gateways are described. Alternatively, you can filter the results.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-transit-gateways 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: TransitGateways

Syntax:

"string" "string" ...

--filters (list)

One or more filters. The possible values are:

• options.propagation-default-route-table-id - The ID of the default propagation route table.

• options.amazon-side-asn - The private ASN for the Amazon side of a BGP session.

• options.association-default-route-table-id - The ID of the default association route table.

• options.auto-accept-shared-attachments - Indicates whether there is automatic acceptance of attachment requests (enable | disable ).

• options.default-route-table-association - Indicates whether resource attachments are automatically associated with the default association route table (enable | disable ).

• options.default-route-table-propagation - Indicates whether resource attachments automatically propagate routes to the default propagation route table (enable | disable ).

• options.dns-support - Indicates whether DNS support is enabled (enable | disable ).

• options.vpn-ecmp-support - Indicates whether Equal Cost Multipath Protocol support is enabled (enable | disable ).

• owner-id - The ID of the AWS account that owns the transit gateway.

• state - The state of the transit gateway (available | deleted | deleting | modifying | pending ).

• transit-gateway-id - The ID of the transit gateway.

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs. The filters supported by a describe operation are documented with the describe operation. For example:

• DescribeAvailabilityZones

• DescribeImages

• DescribeInstances

• DescribeKeyPairs

• DescribeSecurityGroups

• DescribeSnapshots

• DescribeSubnets

• DescribeTags

• DescribeVolumes

• DescribeVpcs

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

The filter values. Filter values are case-sensitive.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--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 .

--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.

--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. 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.

See ‘aws help’ for descriptions of global parameters.
