describe-network-acls¶
Description¶
Describes one or more of your network ACLs.
For more information, see Network ACLs in the Amazon Virtual Private Cloud User Guide .
See also: AWS API Documentation
See ‘aws help’ for descriptions of global parameters.
describe-network-acls 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: NetworkAcls
Synopsis¶

[--filters <value>]
[--dry-run | --no-dry-run]
[--network-acl-ids <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
Options¶
--filters (list)
One or more filters.
association.association-id- The ID of an association ID for the ACL.
association.network-acl-id- The ID of the network ACL involved in the association.
association.subnet-id- The ID of the subnet involved in the association.
default- Indicates whether the ACL is the default network ACL for the VPC.
entry.cidr- The IPv4 CIDR range specified in the entry.
entry.icmp.code- The ICMP code specified in the entry, if any.
entry.icmp.type- The ICMP type specified in the entry, if any.
entry.ipv6-cidr- The IPv6 CIDR range specified in the entry.
entry.port-range.from- The start of the port range specified in the entry.
entry.port-range.to- The end of the port range specified in the entry.
entry.protocol- The protocol specified in the entry (tcp|udp|icmpor a protocol number).
entry.rule-action- Allows or denies the matching traffic (allow|deny).
entry.egress- A Boolean that indicates the type of rule. Specifytruefor egress rules, orfalsefor ingress rules.
entry.rule-number- The number of an entry (in other words, rule) in the set of ACL entries.
network-acl-id- The ID of the network ACL.
owner-id- The ID of the Amazon Web Services account that owns the network ACL.
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 keyOwnerand the valueTeamA, specifytag:Ownerfor the filter name andTeamAfor 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 ACL.(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", ...]
}
...
]
--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 isUnauthorizedOperation.
--network-acl-ids (list)
One or more network ACL IDs.
Default: Describes all your network ACLs.
(string)
Syntax:
"string" "string" ...
--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
NextTokenfrom 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
NextTokenis provided in the command’s output. To resume pagination, provide theNextTokenvalue in thestarting-tokenargument of a subsequent command. Do not use theNextTokenresponse 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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.
See ‘aws help’ for descriptions of global parameters.
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 describe your network ACLs
The following describe-network-acls example retrieves details about your network ACLs.
