LARTC - Jun 2001 - priority of class

I installed configuration:
qdisc cbq
class
qdisc cbq

and split traffic in 2 more classes
tc class add dev eth0 parent 2:0 classid 2:21 cbq avpkt 1000 bandwidth
100Mbit \
rate 70Mbit prio 3 maxburst 20

tc qdisc add dev eth0 parent 2:21 tbf rate 70Mbit buffer 45Kb/8 limit 15Kb

tc class add dev eth0 parent 2:0 classid 2:22 cbq avpkt 1000 bandwidth
100Mbit \
rate 70Mbit prio 4 maxburst 20

tc qdisc add dev eth0 parent 2:22 tbf rate 70Mbit buffer 45Kb/8 limit 15Kb

Actualy results is Ok.I am trying to see influence of "prio" parameter
of
class
and nothing happened.
Please, help me w/ your answer.

I understand that "prio" optiion in tc class is useless
when you add cbq cause here you specifying to which kind
of QDISC your class connected, so can be CBQ, PRIO and etc.
kinds.
Anybody agree w/ me?

I don''t understand your three-line-long sentence.

Please clarify what the exact problem is and give an example where the
prio parameter would not have any effect. Don''t add prio''s
before knowing
what you want.
