Hello,
I'm trying to shape traffic by IP addresses and by 802.1q vlans.
But when I add 802.1q filter filters output looks strange.
Maybe I'm missing some options to TC?
Thanks,

I want to know number of bytes sent by specific customer.
Customer corresponds to SFQ leaf.

When HTB is not shaping (0 dropped packets) difference
is smaller but still considerable.
ifconfig - 63510398 bytes
tc - 61854134 bytes

Hello,
I have some strange problems with shaping. Now I'm testing Linux as
shaping bridge. Redhat Linux 7.3, kernel plain 2.4.23 with latest HTB patch
from devik and PSCHED_CLOCK_SOURCE changed to PSCHED_CPU.

I mean packet schedulers :).

Yes. You are right. If I set HZ to 1024 everything worked OK.

During my tests I'm starting to feel stupid :). Traffic
shaping works quite on its own.
System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB
version 3.6, interfaces eth0 and eth1 are acting as bridge br0.
If TCP shaping almost works, it just exceeds limits UDP
is not shaped. Traffic flo

I'm trying to setup traffic shaping for a customer.
Machine is RedHat 7.3 with kernel-smp-2.4.18-18.7.x.
HZ=512.
But when I try to load link (using netcat and discard /
chargen services) bytes count (tc -s qdisc show, sfq qdisc)
goes quite well over 512kbit (~560kbit). With UDP I can
even go
