Afternoon list :-) I've just been playing a little with 'flent' and noticed that the default 'rrul' test maybe doesn't exercise cake's tin segments as much as it could. Flent graphs EF & CS5 traffic but in both diffserv4 & diffserv8 cake puts that traffic into the same tin. With a diffserv4 config, flent rrul tests tins 0,1 & 3 (Bk, be & voice) but nothing gets put in tin 2 ('streaming video') What am I doing wrong? :-) Again! Kevin
