I'm trying to implement QoS on a 3550, here's the situation. I've got about 400 hosts on my network. One machine is used to ftp large files(2-4gig) to clients. Currently we only transfer these files at night now, because it causes packet loss on our network. I want to be able to give all of the FTP traffic coming from this machine a low priority, telnet traffic on the entire network the highest priority and all other traffic a medium priority, I don't mind giving all FTP traffic on the network the lowest priority but it isn't needed. What's the best way to approach this? I've looked at a lot of the documentation but it's a little overwhelming with all of the options. Thanks for any input.
