Notes and Constraints

EIP

Note the following when using EIPs:

• Each EIP can only be bound to one cloud resource and it has to be in the same region as the resource.
• The EIP remains unchanged:
  • No matter you start or stop the ECS.
  • When you modify its billing mode or bandwidth size.
• If a yearly/monthly EIP is not renewed after it expires, or if the arrears of a pay-per-use EIP are not paid in time, the EIP may be released and cannot be recovered.
• The number of EIPs that you can assign depends on the region. For details, see How Do I Apply for a Higher Quota?
  • Your request for a larger quota will only be approved if your account has valid orders and you are continuously using cloud resources. If you have released resources immediately after subscribing to them multiple times, your quota cannot be increased.
• An EIP that has already been bound to a cloud resource cannot be bound to another resource without first being unbound from the current resource.
• If an EIP is billed on a pay-per-use basis, the maximum bandwidth is subject to the information displayed on the console. If you need more bandwidth, submit a service ticket or contact your account manager.
• If the used EIP bandwidth exceeds the purchased size or is attacked (usually by a DDoS attack), the EIP will be blocked but can still be bound or unbound.
• You can only release unbound EIPs.
• The system preferentially assigns EIPs to you from the ones you released, if any. However, if any of these EIPs is already assigned to another user, it cannot be re-assigned to you.

Bandwidth

• The smallest shared bandwidth that can be purchased is 5 Mbit/s. You can only add pay-per-use EIPs to a shared bandwidth.

• Each account can have a maximum of 5 shared bandwidths. If you need more shared bandwidths, submit a service ticket to request a quota increase.
• A shared bandwidth or dedicated bandwidth can only be used by resources owned by the same account.

• Inbound bandwidth is the bandwidth consumed when data is transferred from the Internet to Huawei Cloud. Outbound bandwidth is the bandwidth consumed when data is transferred from Huawei Cloud to the Internet.
• On July 31, 2020, 00:00:00 GMT+08:00, the rules limiting public bandwidths were changed in Chinese mainland regions, including CN North-Beijing4, CN East-Shanghai1, CN South-Guangzhou, CN Southwest-Guiyang1, and CN North-Ulanqab1.

  On December 10, 2021, 00:00:00 GMT+08:00, the rules limiting public bandwidths were changed in CN-Hong Kong, AP-Bangkok, AP-Singapore, AF-Johannesburg, LA-Mexico City2, LA-Sao Paulo1, and LA-Santiago.

  After the change:

  • If your purchased or modified bandwidth is no more than 10 Mbit/s, the inbound bandwidth will be 10 Mbit/s, and the outbound bandwidth will be the same as the purchased or modified bandwidth.
  • If your purchased or modified bandwidth is more than 10 Mbit/s, both the inbound and outbound bandwidth will be the same as the purchased or modified bandwidth.

Shared Data Packages

• Shared data packages require a one-off payment and take effect immediately after purchase. You cannot specify the effective date.
• Shared data packages cannot be unsubscribed from nor be modified once purchased and cannot be renewed upon expiration.
• Shared data packages are billed by month or year. Once expired, remaining package quota cannot be used any more.
• Shared data packages can only be used by pay-per-use dedicated bandwidth billed by traffic. Two types of shared data packages are available: static BGP (for static BGP bandwidth) and dynamic BGP (for dynamic BGP bandwidth).
• A shared data package cannot be used for bandwidth of a specific EIP.
• A shared data package cannot be used for a shared bandwidth.
• A shared data package cannot be used by EIPs of the premium BGP type.
