[--cidr-block <value>]
[--dry-run | --no-dry-run]

[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

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 the ICMP (1) protocol, or protocol 58 (ICMPv6) with an IPv6 CIDR block.

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 TCP (6) or UDP (17) for the protocol.

Shorthand Syntax:

From=integer,To=integer

JSON Syntax:

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

--protocol (string)

The IP protocol. You can specify all or -1 to mean all protocols. If you specify all , -1 , or a protocol number other than tcp , udp , or icmp , traffic on all ports is allowed, regardless of any ports or ICMP types or codes 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 (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.

--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.

Examples

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
