Modifying an EIP Bandwidth

Scenarios

If an EIP is not added to a shared bandwidth, the EIP uses the dedicated bandwidth no matter how it is billed. A dedicated bandwidth can only be used by a single EIP to limit the rate of the EIP.

This section describes how to increase or decrease the dedicated 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.

If the maximum bandwidth cannot meet your service requirements, you can submit a service ticket to request a higher quota.

**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.
Yearly/Monthly	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 current billing cycle.
Yearly/Monthly	Bandwidth	Decrease bandwidth immediately	The change will take effect immediately.
Pay-per-use	Bandwidth	Increase or decrease the bandwidth	The change will take effect immediately.
Pay-per-use	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

Go to the EIP list page.
Locate the target EIP and choose More > Modify Bandwidth in the Operation column.
- If it is a pay-per-use EIP, the Modify Bandwidth page is displayed.
- If it is a yearly/monthly EIP, select either of the following method to increase or decrease the bandwidth and click Continue.
  - Increase bandwidth
  - Decrease bandwidth immediately
  - Decrease bandwidth
Modify the bandwidth parameters as prompted.

Select "I acknowledge the price change and agree to proceed" and click Submit.

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