This is the case isn't it? Since a switch uses > store-and-forward. That should be the case, yes. Not all switches use the store-and-forward method, but that is irrelevant to your situation, except that the other methods reduce the switching latency that is involved with the store-and-forward method, thus reducing the possible time-out you mention, which would be very unlikely that you met unless it were a very short timeout and/or you were linking millions of switches that ran the circumference of the planet several times over. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
