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.

Restrictions

When you bind a floating IP address, if the floating IP address is in the error state, try unbinding the address first.

You are not allowed to bind a floating IP address that has been bound to a port to another port. You must first unbind the IP address from its original port and bind it to the required port.
