1. API Description

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

This API is used to bind an ENI to a CVM.

An ENI must be bound with one security group at least. To bind it, see AssociateNetworkInterfaceSecurityGroups.
One CVM can be bound with multiple ENIs, but only one can be the primary ENI. For more information about the limits, see ENI Use Limits.
An ENI can only be bound to one CVM.
Only the running or shutdown CVMs can be bound with ENIs. For more information about the CVM status, see InstanceStatus in the Data Types.
An ENI can only be bound to a VPC-based CVM under the same availability zone as the ENI subnet.

This API is completed asynchronously. If you need to query the execution result of an async task, please use the RequestId returned by this API to poll the DescribeVpcTaskResult API.

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.
