ModifyInstanceBandwidth

1. API Description

The API is used to modify the bandwidth of an instance.

Note

• Bandwidth cap differs with different instance models. You can call DescribeInstanceTypes to obtain.

• You can only perform this operation on instances whose status is RUNNING.

• If your current and target bandwidth are both in the free bandwidth scope, the change takes immediate effect.

• If the internetChargeType of your instance is ByBandwidth

  • For a PREPAID instance:

    • Upgrade (target > current) operation will deduct the amount required for this instance purchase. If the balance is insufficient, the request will fail and take effect immediately.

    • Downgrade (target < current) operation will generate an order for the next billing cycle and will take effect by then.

  • For a POSTPAID instance, the change takes immediate effect.

• Use InquiryPriceInstanceBandwidth to query price of bandwidth.

• Use DescribeInstanceInternetStatus to query bandwidth status of an instance.

2. Input Parameters

The following request parameter list only provides API request parameters.

bandwidthOutMbps	Yes	Integer	Bandwidth. Value range: from 1 to maximum supported for the instance model.

3. Output Parameters

Parameter Name	Type	Description
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
