Options

--cidr-block (string)

The IPv4 network range to allow or deny, in CIDR notation (for example 172.16.0.0/24 ).

--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 .

--egress | --ingress (boolean)

Indicates whether to replace the egress rule.

Default: If no value is specified, we replace the ingress rule.

--icmp-type-code (structure)

ICMP protocol: The ICMP or ICMPv6 type and code. Required if specifying protocol 1 (ICMP) or protocol 58 (ICMPv6) with an IPv6 CIDR block.

Code -> (integer)

The ICMP code. A value of -1 means all codes for the specified ICMP type.

Type -> (integer)

The ICMP type. A value of -1 means all types.

Shorthand Syntax:

Code=integer,Type=integer

JSON Syntax:

{
  "Code": integer,
  "Type": integer
}

--ipv6-cidr-block (string)

The IPv6 network range to allow or deny, in CIDR notation (for example 2001:bd8:1234:1a00::/64 ).

--network-acl-id (string)

The ID of the ACL.

--port-range (structure)

TCP or UDP protocols: The range of ports the rule applies to. Required if specifying protocol 6 (TCP) or 17 (UDP).

From -> (integer)

The first port in the range.

To -> (integer)

The last port in the range.

Shorthand Syntax:

From=integer,To=integer

JSON Syntax:

{
  "From": integer,
  "To": integer
}

--protocol (string)

The protocol number. A value of “-1” means all protocols. If you specify “-1” or a protocol number other than “6” (TCP), “17” (UDP), or “1” (ICMP), traffic on all ports is allowed, regardless of any ports or ICMP types or codes that you specify. If you specify protocol “58” (ICMPv6) and specify an IPv4 CIDR block, traffic for all ICMP types and codes allowed, regardless of any that you specify. If you specify protocol “58” (ICMPv6) and specify an IPv6 CIDR block, you must specify an ICMP type and code.

--rule-action (string)

Indicates whether to allow or deny the traffic that matches the rule.

Possible values:

• allow

• deny

--rule-number (integer)

The rule number of the entry to replace.

--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.

--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 replace a network ACL entry

This example replaces an entry for the specified network ACL. The new rule 100 allows ingress traffic from 203.0.113.12/24 on UDP port 53 (DNS) into any associated subnet.

Command:

aws ec2 replace-network-acl-entry --network-acl-id acl-5fb85d36 --ingress --rule-number 100 --protocol udp --port-range From=53,To=53 --cidr-block 203.0.113.12/24 --rule-action allow

Output

None
