Abstract: A computer I/O system which includes a dynamic switch (10) having a plurality of ports (P) and a plurality of link-level facilities, with each link-level facility being attached to an individual one of the ports (P). Whenever the state of a port (P) or its attached link-level facility is changed in such a way that the attached link-level facility's ability to communicate with another link-level facility might be affected, this fact is recognized by a dynamic switch control unit (20) which causes a state change notification (SCN) frame to be transmitted to all other link-level facilities which might be affected. The link-level facilities receiving such a state change notification then determine if any of the associations or potential associations with the link-level facility which caused the state change notification are affected.
