Modifying an EIP Bandwidth

Scenarios

No matter which billing mode is used, if your EIP is not added to a shared bandwidth, it uses a dedicated bandwidth. A dedicated bandwidth can control how much data can be transferred using a single EIP.

This section describes how to increase or decrease the bandwidth size. Changing bandwidth size does not change the EIPs.

When you change the bandwidth size, the bandwidth price and effective time depend on the billing mode, which applies to both dedicated and shared bandwidths. For details, see Table 1.

Decreasing bandwidths may cause packet loss.

Table 1 Impact on billing after bandwidth size change

Billing Mode	Billed By	Change	Impact
Yearly/Monthly	Bandwidth	Increase bandwidth	The change will take effect immediately. The increased bandwidth will be billed accordingly.
	Bandwidth	Decrease bandwidth upon renewal	The change will not take effect immediately. You need to select a new bandwidth size and a renewal duration. The change will take effect in the first billing cycle after a successful renewal. The order can be unsubscribed before the bandwidth takes effect. The bandwidth cannot be modified in the first billing cycle.
Pay-per-use	Bandwidth	Increase or decrease the bandwidth	The change will take effect immediately.
	Traffic	Increase or decrease the bandwidth	The change will take effect immediately. The bandwidth size you set is only used to limit the maximum data transfer rate.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select the desired region and project.
3. Click in the upper left corner and choose Networking > Elastic IP.
4. Locate the row that contains the target EIP in the EIP list, click More in the Operation column, and select Modify Bandwidth.
5. Modify the bandwidth parameters as prompted.

6. Click Next.
7. Click Submit.

You can also select multiple EIPs and click Modify Bandwidth above the list to modify their bandwidths in batches. Only dedicated bandwidths billed on a pay-per-use basis can be modified in batches.
