Notes and Constraints
Updated on 2024-04-08 GMT+08:00
EIP
Note the following when using EIPs:
- Each EIP can only be bound to one cloud resource.
- 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.
- EIPs cannot be transferred across accounts.
- The maximum bandwidth of an EIP is 300 Mbit/s no matter whether it is billed by bandwidth or by traffic.
- 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.
- Within the validity period of a bandwidth used by a yearly/monthly EIP, you can only increase the bandwidth size. You can only reduce the bandwidth size when you renew the subscription.
- 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 the cloud. Outbound bandwidth is the bandwidth consumed when data is transferred from the cloud to the Internet.
