1. API Description

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

This API is used to create an ENI and bind it to a CVM.

  • You can specify private IP addresses and a primary IP when creating an ENI. The specified private IP must be idle and in the same subnet as the ENI.
  • When creating an ENI, you can specify the number of private IPs that you want to apply for. The system will randomly generate private IP addresses.
  • The number of IPs bound with an ENI is limited. For more information, see ENI Use Limits.
  • You can bind an existing security group when creating an ENI.
  • You can bind a tag when creating an ENI. The tag list in the response indicates the tags that have been successfully added.

    Note：

    This API is async. You can call the DescribeVpcTaskResult API to query the task result. When the task is completed, you can continue other tasks.

A maximum of 20 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.
