Cisco sells Gigabit Ethernet linecards for this router, and the situation is quite different in this case. And with most attacks, it's a futile exercise to try to combat them on a Fast Ethernet link, anyway. 8-( > But I'm pretty sure that a C37xx would handle full 100 MBit traffic to a > busy website without any problems. In fact, I know that it does. ;-) (We > did switch to a C12000 shortly after, mainly because we went Gigabit). Of course it does. After all, web traffic is somewhat different from pure DoS traffic. 8-) - 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/
