| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| InstanceId | string | Yes | The ID of the instance. | r-bp1zxszhcgatnx**** |
| BandWidth | long | No | The amount of bandwidth that you want to add. Unit: Mbit/s. The value must be an integer greater than or equal to 0. In most cases, the maximum bandwidth that can be added can be two times the default maximum bandwidth of the current instance type. For more information about the bandwidth specifications supported by different instance types, see Overview . The bandwidth is also subject to the following limits:
If you do not specify this parameter for a standard instance, the bandwidth of the instance is set to two times that of the current bandwidth.
