1. API Description

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

This API is used to create an ENI.

• You can specify private IP addresses and a primary IP when creating an ENI. The specified private IP must be in the same subnet as the ENI and is not occupied.
• When creating an ENI, you can specify the number of private IP addresses that you want to apply for. The system will randomly generate private IP addresses.
• An ENI can only be bound with a limited number of IP addresses. For more information about resource limits, 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 100 requests can be initiated per second for this API.
