  • 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.
