EIP bandwidth plans support bandwidth sharing and transferring on a regional scale. After you purchase an EIP bandwidth plan, you can associate pay-as-you-go elastic IP addresses (EIPs) with the EIP bandwidth plan. This way, the EIPs share the bandwidth of the EIP bandwidth plan. This reduces Internet bandwidth costs.

Associate EIPs with an EIP bandwidth plan

Before you associate EIPs with an EIP bandwidth plan, make sure that the following requirements are met:
After you associate EIPs with an EIP bandwidth plan:
  • Elastic Compute Service (ECS) instances, Server Load Balancer (SLB) instances, and NAT gateways that are associated with the EIPs share the bandwidth of the EIP bandwidth plan.
  • The previous maximum bandwidth of each EIP is invalid. The maximum bandwidth of each EIP equals the maximum bandwidth of the EIP bandwidth plan.
  • The previous billing method of each EIP becomes invalid. You are not charged an additional data transfer fee for each EIP.
  • You are charged a configuration fee for an EIP, regardless of whether the EIP is associated with an EIP bandwidth plan. For more information about EIP configuration fees, see Billing overview.
Note You can associate at most 100 EIPs with each EIP bandwidth plan. To associate more EIPs, request a quota increase. For more information, see Manage quotas.
  1. Log on to the Elastic IP Address console .
  2. In the top navigation bar, select the region where the EIP is created.
  3. On the Elastic IP Addresses page, find the EIP that you want to manage and choose More > Add to Shared Bandwidth Plan in the Actions column.
  4. In the dialog box that appears, select an EIP bandwidth plan and click OK.

Disassociate an EIP from an EIP bandwidth plan

You can disassociate an EIP from an EIP bandwidth plan. After you disassociate the EIP, the maximum bandwidth and the billing method of the EIP are restored to the settings before the EIP is associated with the EIP bandwidth plan.

  1. Log on to the Elastic IP Address console .
  2. In the top navigation bar, select the region where the EIP is created.
  3. On the Elastic IP Addresses page, find the EIP that you want to disassociate and choose More > Remove from Internet Shared Bandwidth in the Actions column.
  4. In the message that appears, click OK.

FAQ

How do I associate an EIP that is associated with an EIP bandwidth plan with another EIP bandwidth plan?

You can first disassociate the EIP from the EIP bandwidth plan, and then associate the EIP with another EIP bandwidth plan. For more information, see Disassociate an EIP from an EIP bandwidth plan and Associate EIPs with an EIP bandwidth plan.

What is the impact if I associate an EIP that is associated with an EIP bandwidth plan with another EIP bandwidth plan?

  • After the EIP is disassociated from the EIP bandwidth plan, the maximum bandwidth and the billing method of the EIP are restored to the settings before the EIP is associated with the EIP bandwidth plan.
  • Internet fees of the EIP may change with the new maximum bandwidth and new billing method after the EIP is associated with another EIP bandwidth plan.
