Abstract
A method for communication of offline status between nodes includes detecting an impending deactivation of a physical port and sending a message from a sending node to a receiving node notifying the receiving node of the impending deactivation of the physical port. The method further includes deactivating the report of any error for the physical port and sending a response from the sending node to the receiving node verifying that deactivation of the physical port.
