tc strange behaviour (some discoveries)
hi All,
seems like a kernel problem
when I do the following on kernel 2.6.12.5
tc qdisc add dev lo root handle 1: htb default 1
tc class add dev lo parent 1: classid 1:1 htb rate 512kbit ceil 1mbit
all works as expected (traffic is limited to 1mbit), but this doesn''t
work the same
way on kernel 2.6.14.3, and actually only ceil has effect (in my
previous message
I mentioned

htb child classes don''t borrow form "parent''s parent class" :(
Dear list,
I have the problem that child classes don''t seem to issue the parent
class to borrow from their parent.
This is a simplified version of my script:
tc qdisc del dev $DEV root
tc qdisc add dev $DEV root handle 1: htb default 10
tc class add dev $DEV parent 1: classid 1:1 htb rate 10mbit
tc class add dev $DEV parent 1:1 classid 1:10 htb rate 1kbit ceil

Why does this script noet work (bandwidth, tc en u32)
Hi,
Can anyone point me out where the script below is wrong?
All I want is that host 172.31.1.1 can only use 10 megabit. If I run
this script on the in-between router nothing happens (the host uses
still the full 100 mbit, tested with iperf) , so i assume that something
must be wrong....

QoS - Ping problem
Hello all,
I have set my QoS solution and now I am facing a little problem...
When I ping to my server it has some lost packages:

What is the reccomended minimum rate for leaf htb class for accurate operation?
Hi,
I''m trying to setup QoS in my TSL box. Following to mailing list reccomendations I changed PSCHED_CPU but can''t get accurate shaping with HTB. I have disabled HYSTERESIS also (by setting it to 0).
I have Intel Celeron 1.8Mhz (TSC supported I think).

question about filter priorities and "tc -d filter show" output
The interface is setup like this:
# tc qdisc del dev eth0 root
# tc qdisc add dev eth0 root handle 1: htb default 2
# tc class add dev eth0 parent 1: classid 1:2 htb rate 20mbit ceil 20mbit
If I add a second class and a filter to send traffic to it like this:
# tc class add dev eth0 parent 1: classid 1:130 htb rate 1Mbit ceil 1Mbit
# tc filter add dev eth0 protocol ip parent 1:0 prio 130 u32

QoS doubt about network machine
Hello all,
I am with a doubt about QoS solution... I have a 4 Mbit backbone

HTB traffic shaping odd effects
Hi,
I''m trying to perform some (what I consider) basic traffic shaping on
our network utilising HTB. I have mostly reused the example on the
lartc.org site:

tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k

HTB: Problem with excess bandwidth distribution
Hello,
I have a serious problem with HTB which I wasn''t able to solve myself.
I run a masquerading router with ppp0 as interface to the Internet.
Three clients need to share a downstream of 1 MBit, which I want
to divide with tc.
When I see a packet being forwarded to one of these clients, I give
it the appropriate unique mark:
iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

OpenSwan traffic shaping with HTB & sfq
Hi All,
I''ve got an interoffice IPSEC VPN in place that I''m trying to give
priority to terminal service (tcp 3389) traffic.
I''ve created rules at each end, but have hit a bit of a dillemma. As
the data is encrypted I must also give highest priority to protocol 50
otherwise the priority is lost as the packet gets encrypted.
When I do this however, I can''t

Creating a contended section of bandwidth with HTB and IMQ
Hi All,
I''m trying to create a contended section of bandwidth using IMQ. I have the
imq0 device up and running, with traffic passing through it.
Firstly, I need to throttle the entire device imq0 to 2mbit/s.
I would then like to add throttle rules for individual IP addresses, allowing
them to pass up to 512kbit/s each, as long as imq0 has not reached its
2mbit/s.
