Zusammenfassung:	A method and system for detecting orphaned CLS primitives in a fibre channel network having a fibre channel switch element coupled to an arbitrated loop is provided. The method includes, sending an OPN primitive to a switch element port's own AL_PA to open a connection with itself; and determining if a CLS primitive is received within a loop a latency period. If a CLS primitive is received within the latency period then the CLS primitive is classified as an orphan and the orphaned CLS primitive is removed by the switch element by enabling a firmware based removal feature. The switch element includes a port that arbitrates for the arbitrated loop ownership and sends an OPN primitive to its own AL_PA.
