“real” work is performed on the loop while it is underway. Therefore, it is wise to have a measure of visibility and control over LIP generation. This is the advantage of P4459A Name Server. It limits the effects of a LIP on other devices in the network. - Page 15 LIP. Obviously, this interrupts any traffic in progress on that switch port, or on another switch port that is involved in a connection with a device on that switch port. However, it need not disrupt communications on any other switch port.
