Hello, I''ve discoverd hfsc few days ago, and for me it''s great ! I''am running it on linux 2.4.26 with vlan interfaces using iANS. During tests I''ve discovered few problems. My set of rules is quite big: root@hades:/home/system/scr/etc/hfsc_rebuild# cat tc.batch | grep hfsc | wc -l 27900 and alwyas when I delete the root hfsc class, machine is loosing network conectivity for about 15 seconds. The second problems is that after reloading set of rules machine is losing network conectivity on some virtual interfaces. As I remember the same problem was present in the earliest version of linux kernels (< 2.4.26) in htb code. -- Tomasz Paszkowski
