You can call this operation to modify the bandwidth configurations of an 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:

  • If you upgrade the outbound public bandwidth (InternetMaxBandwidthOut) of a subscription (PrePaid) instance from 0 Mbit/s when you modify its bandwidth configurations, 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 its bandwidth configurations, no public IP address is 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 its outbound public bandwidth (InternetMaxBandwidthOut) from 0 Mbit/s.
  • After the bandwidth is upgraded, AutoPay is set to true by default. Make sure that you have sufficient balance in your account. Otherwise, your order becomes invalid and must be canceled. If your account balance is insufficient, you can set AutoPay to false to generate an unpaid order. Then, you can log on to the ECS console to pay for the order.
  • You can downgrade the public bandwidth of each subscription instance a maximum of three times. A maximum of three refunds for price difference can be made.
  • The price difference is refunded to the payment account you used. Used coupons cannot be refunded.
  • Each time a modification of bandwidth configurations succeeds, you cannot modify the bandwidth of the instance again within five minutes.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

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:

  • When the purchased outbound public bandwidth is less than or equal to 10 Mbit/s, the valid values of InternetMaxBandwidthIn are 1 to 10 and the default value is 10.
  • When the purchased outbound public bandwidth is greater than 10 Mbit/s, the valid values of InternetMaxBandwidthIn are 1 to the InternetMaxBandwidthOut value and the default value is the InternetMaxBandwidthOut value.
NetworkChargeType String No PayByTraffic

The billing method for network usage. Valid values:

  • PayByBandwidth: pay-by-bandwidth
  • PayByTraffic: pay-by-traffic
Note When the pay-by-traffic billing method is used, the peak inbound and outbound bandwidths are both the upper limits of bandwidths and for reference only. In the event of resource contention, these peak bandwidths cannot be guaranteed. If you want guaranteed bandwidths for your instance, use the pay-by-bandwidth billing method.
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 the minute (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 the hour (hh).

AutoPay Boolean No true

Specifies whether to enable automatic payment. Valid values:

  • true: Automatic payment is enabled. After bandwidth configurations are upgraded, the payment is automatically made. Make sure that you have sufficient balance in your account when you set Autopay to true. If your account balance is insufficient, your order cannot be paid in the ECS console and becomes invalid. You have to cancel it.
  • false: Automatic payment is disabled. After bandwidth configurations are upgraded, an order is generated but is not paid. If your account balance is insufficient, you can set AutoPay to false to generate an unpaid order. Then, you can log on to the ECS console to pay for the order.

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 it is unique among different requests. The ClientToken value must contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.
