CreateSubnet

CreateSubnet

1. API Description

This API is used to create a subnet.

Prerequisites

Before creating a subnet, you can call DescribeSubnetAvailableResources to check the available zones.

Note

• Subnet quota is limited. If you need more, please contact Zenlayer Support.

• This API is an async API. A subnet ID list is returned after the creation request is sent. However, it does not mean the creation has been completed. The status of the subnet will be Creating during the creation. You can call DescribeSubnets to query the status of the subnet. If the status changes from Creating to Available, it means that the subnet has been created successfully; Failed means the subnet has been created failed. Any operations on the subnets are not allowed while creating.

2. Input Parameters

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
cidrBlock	Yes	String	CIDR block of the subnet. The optional values are as follows: 10.0.0.0/24, 172.16.0.0/24, 192.168.0.0/24 and their subsets. The subnet IP ranges cannot be overlapped.
subnetName	Yes	String	Subnet name to be displayed. This parameter must start and end with a number or a letter, containing 2 to 63 characters. Only letters, numbers, - and periods (.) are supported.
zoneId	Yes	String	Zone ID of subnet.
subnetDescription	No	String	Subnet description.

3. Output Parameters

Parameter Name	Type	Description
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
subnetId	String	Subnet ID.
