Updating a Floating IP Address

Function

This API is used to update a floating IP address.

During the update, the ID of the floating IP address must be provided in the URL.

If port_id is left blank, the floating IP address has been unbound from the port.

Note

This API has the following constraints:

• If a floating IP address that you are binding is in the error state, unbind the IP address first.

• Do not associate a port that has a floating IP address associated to another floating IP address. You must first disassociate the port from the IP address and then associate it with another IP address.

• This API cannot be used to bind an EIP to or unbind an EIP from a dedicated load balancer.

• In eu-de, EIPs of the Dedicated Load Balancer (5_gray) type cannot be assigned anymore. You can assign EIPs of the BGP (5_bgp) type.

• Existing EIPs of the Dedicated Load Balancer (5_gray) type can be bound to dedicated or shared load balancers.

  • The EIP console cannot be used to bind EIPs to or unbind them from dedicated load balancers.

  • You can use APIs to bind EIPs to or unbind them from dedicated load balancers. For details, see Binding an EIP and Unbinding an EIP.

  • EIPs of this type can be bound to or unbound from shared load balancers using the EIP console or APIs.

  • You are advised to bind BGP EIPs to or unbind them from dedicated load balancers.

• Do not add EIPs of the dedicated load balancer type (5_gray) and other types to the same shared bandwidth. Otherwise, the bandwidth limit policy will not take effect.
