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 an EIP bandwidth plan. This way, the EIPs share the bandwidth of the EIP bandwidth plan. This reduces Internet bandwidth costs.

Associate an EIP with an EIP bandwidth plan

Before you associate an EIP with an EIP bandwidth plan, make sure that the following requirements are met:
After you associate an EIP with an EIP bandwidth plan:
  • Elastic Compute Service (ECS) instances, Server Load Balancer (SLB) instances, and NAT gateways that are associated with the EIP share the bandwidth of the EIP bandwidth plan.
  • The previous maximum bandwidth of the EIP becomes invalid. The maximum bandwidth of the EIP is the same as the maximum bandwidth of the EIP bandwidth plan.
  • The previous EIP billing method becomes invalid. The EIP functions as a public IP address. You are not charged data transfer fee for the EIP.
  • You are charged an instance fee for the EIP, regardless of whether the EIP is associated with an EIP bandwidth plan.
Note
  • After you associate an EIP with a NAT gateway and then associate the EIP with an EIP bandwidth plan, your service may be temporarily interrupted. Proceed with caution.
  • 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 deployed.
  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 deployed.
  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.
