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.
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.

3. Output Parameters
| Parameter Name |
Type |
Description |
| NetworkInterface |
NetworkInterface |
ENI instance. |
| RequestId |
