Hi, All, When I use CBQ, what should I put for "avpkt"? I saw all the examples using 1000, but if I have a lot of voice packets which are very small, will "avpkt 1000" cause any problem? Another thing is, does CBQ support "default" as HTB does (ex: tc qdisc add dev eth0 root handle 1: htb default 12)? How can I put "all other traffic" into certain class? Thanks, James
