describe-network-interfaces¶

Description¶

Describes one or more of your network interfaces.

If you have a large number of network interfaces, the operation fails unless you use pagination or one of the following filters: group-id , mac-address , private-dns-name , private-ip-address , private-dns-name , subnet-id , or vpc-id .

Warning

We strongly recommend using only paginated requests. Unpaginated requests are susceptible to throttling and timeouts.

--network-interface-ids (list)

The network interface IDs.

Default: Describes all your network interfaces.

(string)

Syntax:

"string" "string" ...

--filters (list)

One or more filters.

association.allocation-id - The allocation ID returned when you allocated the Elastic IP address (IPv4) for your network interface.

addresses.association.owner-id - The owner ID of the addresses associated with the network interface.

addresses.association.public-ip - The association ID returned when the network interface was associated with the Elastic IP address (IPv4).

attachment.instance-owner-id - The owner ID of the instance to which the network interface is attached.

attachment.status - The status of the attachment (attaching | attached | detaching | detached ).

availability-zone - The Availability Zone of the network interface.

description - The description of the network interface.

group-id - The ID of a security group associated with the network interface.

ipv6-addresses.ipv6-address - An IPv6 address associated with the network interface.

requester-id - The alias or Amazon Web Services account ID of the principal or service that created the network interface.

requester-managed - Indicates whether the network interface is being managed by an Amazon Web Services service (for example, Amazon Web Services Management Console, Auto Scaling, and so on).

source-dest-check - Indicates whether the network interface performs source/destination checking. A value of true means checking is enabled, and false means checking is disabled. The value must be false for the network interface to perform network address translation (NAT) in your VPC.

status - The status of the network interface. If the network interface is not attached to an instance, the status is available ; if a network interface is attached to an instance the status is in-use .

subnet-id - The ID of the subnet for the network interface.

tag :<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA , specify tag:Owner for the filter name and TeamA for the filter value.

tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

vpc-id - The ID of the VPC for the network interface.

(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.

If you specify multiple filters, the filters are joined with an AND , and the request returns only results that match all of the specified filters.

Name -> (string)

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

Values -> (list)

The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR , and the request returns all results that match any of the specified values.

(string)

Shorthand Syntax:

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

JSON Syntax:

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

--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. 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.

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 .
