Bind ENI with CVM

Last updated: 2020-06-04 18:08:38


    This is a legacy API which has been hidden and will no longer be updated. We recommend using the new VPC API 3.0 which is standardized and faster.

    1. API Description

    This API (AttachNetworkInterface) is used to request private IP for ENIs.
    Domain for API request:

    1) A CVM can bind multiple ENIs but one primary ENI.
    2) An ENI can only be bound to one CVM.
    3) Only CVMs that are in a running/shutdown status can bind ENIs. For details on the CVM status, refer to Query CVM Information.
    4) ENIs must be bound to a VPC CVM, and the availability zone of the CVM must be the same as that of ENIs.

    2. Input Parameters

    The following request parameter list only provides API request parameters. Common request parameters need to be added when the API is called. For more information, refer to Common Request Parameters. The Action field for this API is AttachNetworkInterface.

    Parameter Name Required Type Description
