Yes and no. CEF is {src, dst} hash IIRC, and "per-flow" usually means {src, srcport, dst, dstport, [proto, tos]} hash in my experience.

Correct. The Catalyst 6500/7600 OSR with Sup2/Sup32/Sup720 can be configured to hash based on L4 ports in addition to the IP addresses (for IPv4): http://puck.nether.net/pipermail/cisco-nsp/2005-December/026952.html This is handy when you have multiple "striped" TCP connections between a single pair of hosts, and want them to be able to use multiple equal-cost paths, but still want to avoid reordering inside each connection (as you would inevitably get with per-packet load sharing). -- Simon.
