allocate-ipam-pool-cidr¶

Description¶

Allocate a CIDR from an IPAM pool. The Region you use should be the IPAM pool locale. The locale is the Amazon Web Services Region where this IPAM pool is available for allocations.

In IPAM, an allocation is a CIDR assignment from an IPAM pool to another IPAM pool or to a resource. For more information, see Allocate CIDRs in the Amazon VPC IPAM User Guide .

Note

This action creates an allocation with strong consistency. The returned CIDR will not overlap with any other allocations from the same pool.

Options¶

--dry-run | --no-dry-run (boolean)

A check for 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 .

--ipam-pool-id (string)

The ID of the IPAM pool from which you would like to allocate a CIDR.

--cidr (string)

The CIDR you would like to allocate from the IPAM pool. Note the following:

If there is no DefaultNetmaskLength allocation rule set on the pool, you must specify either the NetmaskLength or the CIDR.

If the DefaultNetmaskLength allocation rule is set on the pool, you can specify either the NetmaskLength or the CIDR and the DefaultNetmaskLength allocation rule will be ignored.

Possible values: Any available IPv4 or IPv6 CIDR.

--netmask-length (integer)

The netmask length of the CIDR you would like to allocate from the IPAM pool. Note the following:

If there is no DefaultNetmaskLength allocation rule set on the pool, you must specify either the NetmaskLength or the CIDR.

If the DefaultNetmaskLength allocation rule is set on the pool, you can specify either the NetmaskLength or the CIDR and the DefaultNetmaskLength allocation rule will be ignored.

Possible netmask lengths for IPv4 addresses are 0 - 32. Possible netmask lengths for IPv6 addresses are 0 - 128.

--client-token (string)

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see Ensuring Idempotency .

--description (string)

A description for the allocation.

--preview-next-cidr | --no-preview-next-cidr (boolean)

A preview of the next available CIDR in a pool.

--allowed-cidrs (list)

Include a particular CIDR range that can be returned by the pool. Allowed CIDRs are only allowed if using netmask length for allocation.

(string)

Syntax:

"string" "string" ...

--disallowed-cidrs (list)

Exclude a particular CIDR range from being returned by the pool. Disallowed CIDRs are only allowed if using netmask length for allocation.

(string)

Syntax:

"string" "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.

--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.

--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 .

To allocate a CIDR from an IPAM pool

The following allocate-ipam-pool-cidr example allocates a CIDR from an IPAM pool.

(Linux):

aws ec2 allocate-ipam-pool-cidr \
    --ipam-pool-id ipam-pool-0533048da7d823723 \
    --netmask-length 24

(Windows):

aws ec2 allocate-ipam-pool-cidr ^
   --ipam-pool-id ipam-pool-0533048da7d823723 ^
   --netmask-length 24

Output:

{
    "IpamPoolAllocation": {
        "Cidr": "10.0.0.0/24",
        "IpamPoolAllocationId": "ipam-pool-alloc-018ecc28043b54ba38e2cd99943cebfbd",
        "ResourceType": "custom",
        "ResourceOwner": "123456789012"
    }
}

For more information, see Manually allocate a CIDR to a pool to reserve IP address space in the Amazon VPC IPAM User Guide.

Output¶

IpamPoolAllocation -> (structure)

Information about the allocation created.

Cidr -> (string)

The CIDR for the allocation. A CIDR is a representation of an IP address and its associated network mask (or netmask) and refers to a range of IP addresses. An IPv4 CIDR example is 10.24.34.0/23 . An IPv6 CIDR example is 2001:DB8::/32 .

IpamPoolAllocationId -> (string)

The ID of an allocation.

Description -> (string)

A description of the pool allocation.

ResourceId -> (string)

The ID of the resource.

ResourceType -> (string)

The type of the resource.

ResourceRegion -> (string)

The Amazon Web Services Region of the resource.
