I have never seen one that panned out (at least not since the high-end-10mbps days). Just to be clear, I am asking for an example of a Gigabit Ethernet switch that supports cut-through switching. I contend that there is no such beast commercially available today. (It would be even more interesting if it could switch 9000-octet jumbo frames, too.) I'm sure someone is going to point me to a $10,000/port monster, and while that's not very feasible for my needs, it would still be interesting. -andy - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
