Subject: [LARTC] Traffic is exceeding limits
Date: Wed, 18 Dec 2002 12:23:13 +0000	[thread overview]
Message-ID: <marc-lartc-104021428723515@msgid-missing> (raw)


  I'm trying to setup traffic shaping for a customer.
Machine is RedHat 7.3 with kernel-smp-2.4.18-18.7.x.
HZQ2.

  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 over 1mbit.

  What can be done to ensure tighter limits?

  Thanks,

  Mindaugas

  burst and cburst were set by tc and equals 2175b. r2q = 10.

  No more tc rules exists now.

$TC qdisc del dev eth0 root
$TC qdisc del dev eth1 root

$TC qdisc add dev eth0 root handle 1: htb
$TC qdisc add dev eth1 root handle 1: htb

$TC class add dev eth0 parent 1: classid 1:200 htb rate 512kbit
$TC class add dev eth1 parent 1: classid 1:200 htb rate 512kbit

$TC qdisc add dev eth0 parent 1:200 handle 200: sfq perturb 10
$TC qdisc add dev eth1 parent 1:200 handle 200: sfq perturb 10

$TC filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip src $ip
flowid 1:200
$TC filter add dev eth1 parent 1: protocol ip prio 1 u32 match ip dst $ip
flowid 1:200
