Actually you might be pleasantly surprised with an IPv6 attack on a 3550 - I suspect the IPv4 traffic would just keep on truckin', less any routing updates that might arrive during the event. I had a customer with about 14k public IP addresses passing through a 3550. The machine was crazy stressed and the management engine was crashing several times a day - management would report it down for the duration of a reboot, but traffic otherwise kept moving. The processor seems to instruct the ASICs to forward as needed, then it sits quietly ...
