As far as i know the 3550 does not support Netflow. The modular 4500 and 6500 switches support netflow but not the 3550/3560 switches.

If you meant that is all traffics then I would recommend you to use a span-port feature on the switch.

Maybe it'll overflow on the destination port if you are copying all of source interfaces on switch.

Hopes this helps

If you don't want to spend much money, purchase a low-end router between the server and the rest of the network and the router will provide the NetFlow feature that you are missing from the switch.

The Catalyst 3550 was designed for end-user connectivity, not server farm. That's the reason certain features such as NetFlow are missing from that family.

Good idea, what router would be good just to pass through data? 1841?

For 100Mbps, you need at least a 2851.

For 1Gbps, you need a 7200 with a NPE-G2 (very expensive option).
