Hello,
I have (from years on few servers) HTB+IMQ traffic shaping.
Last week i've upgraded my linux server to new release (opensuse 10.3 to
13.1)
Kernel 2.6.22.12 to Kernel 3.11.6.4
iptables 1.3.8 to iptables 1.4.19
After upgrade in general everythings works, but shaping is not accurate
Main link is 80Mb/s so limit on HTB script is 80mibit, on old kernel it
reaches
over 10240 kbytes and it was fine.
Now on new kernel it reach about 7800kbytes in maximum and cannot go higher.
(workaround for me is set main limit in HTB scripts to 130mibit and it can
reach output about 10240kbytes)
What I saw first:
tc -s class show dev imq0
[.....]
class htb 1:13 parent 1:1 prio 1 rate 200000bit ceil 200000bit burst
1492b cburst 1492b
Sent 5746052 bytes 25213 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
lended: 25213 borrowed: 0 giants: 0
tokens: 832500 ctokens: 832500
[...]
rate shows 0bit,
so as I found in maillist archive I set
echo 1 > /sys/module/sch_htb/parameters/htb_rate_est
and restart scripts. Now rate shows values, but shapeing is
still not accurate.
Part of script:
tc qdisc add dev imq0 root handle 1:0 htb default 10
tc qdisc add dev imq1 root handle 2:0 htb default 10
# Main queue
tc class add dev imq0 parent 1:0 classid 1:1 htb rate 500mibit ceil 500mibit
tc class add dev imq1 parent 2:0 classid 2:1 htb rate 500mibit ceil 500mibit
# Internet link
tc class add dev imq0 parent 1:1 classid 1:2 htb rate 80mibit ceil 80mibit

Pealse help ....
