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.

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.
