It's all CPU on an ISR or 7200. What matters is the packet size. It can handle flows with large packets beyond what Cisco would officially recommend them for (i.e. a file transfer), but throw a lot of tiny UDP at it you'll quickly run out of headroom far below what you would expect. ~Seth _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
