Desvincula una interfaz de red elástica (ENI) de una instancia de Elastic Compute Service (ECS).
Descripción de la operación
Tome en cuenta los siguientes puntos:
-
No puede desvincular la ENI principal de una instancia.
-
Asegúrese de que la ENI que se va a desvincular esté en estado Detaching (Unbinding) o InUse (Bound).
-
Asegúrese de que la instancia de la que desea desvincular una ENI esté en estado Running (Running) o Stopped (Stopped).
-
La operación DetachNetworkInterface es una operación asíncrona. Después de llamar a esta operación para desvincular una ENI, puede verificar el estado o los eventos de la ENI para determinar si se ha desvinculado. La siguiente figura muestra las transiciones entre los estados de la ENI.

-
Si la ENI está en estado Detaching, significa que se envió la solicitud de desvinculación y la ENI se está desvinculando de la instancia asociada.
-
Si la ENI está en estado Available, significa que la ENI ya se desvinculó de la instancia asociada.
-
Si la ENI se queda atascada en el estado Detaching, es posible que no se pueda desvincular de la instancia asociada debido a razones específicas. Por ejemplo, la ENI podría no desvincularse porque el sistema operativo de la instancia no respondió a la solicitud de desvinculación. Si ocurre este problema, puede volver a enviar la solicitud para desvincular la ENI. Si el problema persiste, reinicie la instancia.

| 400 | InvalidParams.EniId | %s | The specified EniId parameter is invalid. |
| 400 | InvalidParameter.EniNotBelongEcs | %s | The specified ENI does not belong to the specified ECS instance. For more information, see the actual return result of the %s placeholder in the error message. You can call DescribeInstances to view the ENI IDs attached to the specified ECS instance. |
| 400 | InvalidOperation.EniHotPlugNotSupported | The ENI with high-performance traffic mode cannot be hot-plugged. Please stop the ECS instance to which the ENI is attached, and try again. | An ENI with high-performance communication mode enabled does not support hot unplugging. Stop the ECS instance to which the ENI is mounted and try again. |
| 500 | InternalError | The request processing has failed due to some unknown error, exception or failure. | An internal error has occurred. Try again later. |
| 500 | InvalidSecurityGroupId.EniMustHaveSecurityGroup | The specified network card does not have an associated security group. | The specified NIC is not associated with a security group. |
