Based on CBWFQ, How can I setup QOS for FTP traffic across the WAN on 26xx rotuer over frame relay. The access-list dont seem to work because the data port on FTP is randomly agreed by client/server. I want to give a certain percentage only to FTP. I know NBAR can classify FTP, but what is the overhead of NBAR classification compared to a regular access-list on a 2600 / 3600 and 7200 NPE-300 router ?
