1. API Description
Domain name for API request: vpc.tencentcloudapi.com.
This API (CreateNetworkInterface) is used to create ENIs.
- When creating an ENI, you can specify private IPs, including a primary IP, for it. The specified private IPs must be in the same subnet as the ENI, and cannot be in use.
- You can specify the number of the private IPs you want to apply for. The private IPs will be generated by the system randomly.
- You can bind an existing security group to the ENI.
A maximum of 100 requests can be initiated per second for this API.
Note: This API supports Finance regions. Since Finance regions and non-Finance regions are isolated and not interconnected. If the common parameter Region is a Finance region (such as ap-shanghai-fsi), you need to specify a domain name containing the Finance region that should be identical to the value of Region field, for example: vpc.ap-shanghai-fsi.tencentcloudapi.com.
