CreateNetworkInterface - Elastic Compute Service - Alibaba Cloud ドキュメントセンター

Creates an elastic network interface (ENI). When you call this operation, you can specify parameters, such as VSwitchId and PrimaryIpAddress, in the request.

Operation description

Usage notes

Take note of the following items:

This operation is a synchronous operation. After an ENI is created, it immediately enters the Available (Available) state and can be attached to an Elastic Compute Service (ECS) instance.
If NetworkInterfaceId is empty in the response, no ENI is created. Call the operation again to create an ENI.
An ENI can be attached only to a single instance that resides in a virtual private cloud (VPC).
When an ENI is detached from an instance and attached to another instance, the attributes of the ENI remain unchanged and network traffic is redirected to the new instance.
When you call this operation to create an ENI, you can assign up to 49 secondary private IP addresses to the ENI.
If you want to assign IPv6 addresses when you create an ENI, make sure that IPv6 is enabled for the vSwitch with which you want to associate the ENI. For more information, see What is an IPv6 gateway?
A quota is imposed on the number of ENIs that can be created per Alibaba Cloud region per account. You can view the quota in the ECS console. For more information, see View and increase resource quotas.

For information about examples on how to call this operation, see Create an ENI.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
