Thread-topic: [LARTC] prio not seeming to work
Two questions

1.)  When you type tc class ls dev ethx
        - Do you see that both ftp streams are flowing into their proper
class; 1:1, 1:3?

2.)  Are you sending enough traffic to reach the point of congestion on
you link? 
        - If your not then it will service all the traffic at the same
rate.

Hello,

I am trying to mess with a prio type qdisc, and must be missing
something. 
Here's my sample code:

tc qdisc add dev eth0 root handle 1: prio tc filter add dev eth0 parent
1:0 prio 1 protocol ip u32 \
  match ip dst 208.0.0.0/8 flowid 1:1
tc filter add dev eth0 parent 1:0 prio 3 protocol ip u32 \
  match ip dst 0.0.0.0/0 flowid 1:3

I would assume that any traffic going to 208.x.x.x should be getting
priority over all other traffic.  But when I set up two simultaneous FTP
uploads, one to a server in the 208.x.x.x block and one to another not
in that block, both end up at the same transfer rate.. This is going
into an ADSL line.

What am I missing?

Bob
