CreateSubnet

最后更新时间：2024-11-25 20:03:33

    1. API Description

    Domain name for API request: vpc.intl.tencentcloudapi.com.

    This API is used to create a subnet.

    • You must create a VPC instance before creating a subnet.
    • After the subnet is successfully created, its IP address range cannot be modified. The subnet IP address range must fall within the VPC IP address range. They can be the same if the VPC instance has only one subnet. We recommend that you keep the subnet IP address range within the VPC IP address range to reserve IP address ranges for other subnets.
    • The subnet mask of the smallest IP address range that can be created is 28 (16 IP addresses), and that of the largest IP address range is 16 (65,536 IP addresses).
    • IP address ranges of different subnets cannot overlap with each other within the same VPC instance.
    • A subnet is automatically associated with the default route table once created.
    • You can bind a tag when creating a subnet. The tag list in the response indicates the tags that have been successfully added.

    A maximum of 100 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: CreateSubnet.
    Version Yes String Common Params. The value used for this API: 2017-03-12.
    Region Yes String Common Params. For more information, please see the list of regions supported by the product.
    VpcId Yes String The ID of the VPC instance to be operated on. You can obtain the parameter value from the VpcId field in the returned result of DescribeVpcs API.
    SubnetName Yes String The subnet name. The maximum length is 60 bytes.
    CidrBlock Yes String The subnet IP address range. It must be within the VPC IP address range. Subnet IP address ranges cannot overlap with each other within the same VPC.
    Zone Yes String The ID of the availability zone in which the subnet resides. You can set up disaster recovery across availability zones by choosing different availability zones for different subnets.
    Tags.N No Array of Tag Bound tags, such as [{"Key": "city", "Value": "shanghai"}].
    CdcId No String CDC instance ID

    3. Output Parameters

    Parameter Name Type Description
    Subnet Subnet Subnet object.
    RequestId String The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
