Bob,

Sorry, actually you need this command tc -s -d class ls dev ethx.  Just
so you know you can sub "class" out with "qdisc" or "filter".  This will
show stats in detail.  Ex. Packets flowing through your queue.  

 Do you have a priority assigned to the class also?  I see one filter
has a higher priority so it should get more packets than the other;
which I know is what your trying to do.

Hi John,

1. Hmm, I guess not:

[root@bob ~]# tc class ls dev eth0
class prio 1:1 parent 1:
class prio 1:2 parent 1:
class prio 1:3 parent 1:

Am I missing something in my short & sweet little script?  Again, it is:

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

2. I'm definitely saturating my 384k upstream.

Bob
