I am testing MLS on a cat5500 and have not been able to demonstrate any throughput improvement using FTP as a test application. The cat5500 has SupIII (4.5.12), RSM (12.0.7T) with NFFCII and 3 24port 10/100 ethernet line cards. I have 7 Vlans configured and the mls settings on both the RSM and SupIII. When FTP is run inter VLAN the throughput is same whether I have MLS enabled or not on the SupIII card. When MLS is enabled I have verified functionality using the various show mls commands so I am sure its working I just don't see any throughput improvement. Is this a function of ftp client and server performance (using laptops with 10/100 ethernet cards on NT)? Should I use a different application or unix client / server to test throughput? If someone has any information I would appreciate your experience.
