Modifies the bandwidth configurations of an Elastic Compute Service (ECS) instance. You can modify the bandwidth configurations of an instance to improve network performance.
Description
When you call this operation, take note of the following items:
- As of November 27, 2020, the maximum bandwidth value available for you to create ECS instances or to change ECS instance configurations is subject to throttling policies for your account. To increase the maximum bandwidth value, submit a ticket. The following throttling policies apply:
- Within a single region, the sum of actual peak bandwidths of all ECS instances that use the pay-by-traffic billing method for network usage cannot exceed 5 Gbit/s.
- Within a single region, the sum of actual peak bandwidths of all ECS instances that use the pay-by-bandwidth billing method for network usage cannot exceed 50 Gbit/s.
- If you upgrade the outbound public bandwidth (InternetMaxBandwidthOut) of a subscription (PrePaid) instance from 0 Mbit/s when you modify the bandwidth configurations of the instance, a public IP address is automatically assigned to the instance.
- If you upgrade the outbound public bandwidth (InternetMaxBandwidthOut) of a pay-as-you-go (PostPaid) instance from 0 Mbit/s when you modify the bandwidth configurations of the instance, no public IP address is automatically assigned to the instance. You must call the AllocatePublicIpAddress operation to assign a public IP address to the instance.
- An instance in the classic network must be in the Stopped state before you can upgrade the outbound public bandwidth (InternetMaxBandwidthOut) of the instance from 0 Mbit/s.
- After the bandwidth is upgraded, AutoPay is set to true by default and the payment is automatically made. Maintain a sufficient account balance. Otherwise, your order becomes invalid and must be canceled. If your account balance is insufficient, you can set AutoPay to false. When you call the ModifyInstanceNetworkSpec operation, an unpaid order is generated. Then, you can log on to the ECS console to pay for the order.
- The price difference is refunded to the payment account that you used. Vouchers or coupons that have been redeemed cannot be returned.

Request parameters
Parameter | Type | Required | Example | Description |
---|---|---|---|---|
Action | String | Yes | ModifyInstanceNetworkSpec | The operation that you want to perform. Set the value to ModifyInstanceNetworkSpec. |
InstanceId | String | Yes | i-bp67acfmxazb4**** | The ID of the instance for which you want to modify bandwidth configurations. |
InternetMaxBandwidthOut | Integer | No | 10 | The maximum outbound public bandwidth. Unit: Mbit/s. Valid values: 0 to 100. |
InternetMaxBandwidthIn | Integer | No | 10 | The maximum inbound public bandwidth. Unit: Mbit/s. Valid values:
|
ISP | String | No | null | Note This parameter is in invitational preview and is unavailable for general users. |
NetworkChargeType | String | No | PayByTraffic | The billing method for network usage. Valid values:
Note When the pay-by-traffic billing method for network usage is used, the maximum inbound and outbound bandwidth values are used as the upper limits of bandwidths instead of guaranteed performance specifications. In scenarios where demand outstrips resource supplies, these maximum bandwidths may be limited. If you want guaranteed bandwidths for your instance, use the pay-by-bandwidth billing method for network usage. |
AllocatePublicIp | Boolean | No | false | Specifies whether to assign a public IP address. Default value: false. |
StartTime | String | No | 2017-12-05T22:40Z | The start time of the temporary bandwidth upgrade. Specify the time in the ISO 8601 standard in the yyyy-MM-ddThh:mmZ format. The time must be in UTC and accurate to minutes (mm). |
EndTime | String | No | 2017-12-06T22Z | The end time of the temporary bandwidth upgrade. Specify the time in the ISO 8601 standard in the yyyy-MM-ddThhZ format. The time must be in UTC and accurate to hours (hh). Note The interval between the end time and the start time of the temporary bandwidth upgrade must be greater than or equal to 3 hours. |
AutoPay | Boolean | No | true | Specifies whether to automatically complete the payment. Valid values:
Default value: true. |
ClientToken | String | No | 123e4567-e89b-12d3-a456-426655440000 | The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that the value is unique among different requests. The ClientToken value can only contain ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. |
