[LARTC] An example of prio qdisc please...

[Emmanuel Lacour]

I simply wan't to give higher priority for esp protocol.

Could someone give me an example (I think using prio qdisc and u32
filter???)

have you read the docs? If not, do so to understand how it works and what

Of course, I did it already, the lartc howto is a really good doc, but
all of this is not really easy so by giving me this example I will be
able to understand more and do what I wan't.

Thanks!

Hi there
This is ver infornmative
I've long wanted priority of some protocol over the other.
Now my question is:
	Can i use this with htb?

I want:
	o ip 172.16.0.5 bandwidth restriction of 32 kbps (htb ceil)
	o ip 172.16.0.49 bandwidth restriction of 64 kbps (htb ceil)
	o protocol 23 priority over protocol 80

U see, I don't want to limit "protocol 80" to some bandwidth
restriction so that "protocol 23" gets the rest available bandwidth
I just want "proto 23" packets priority over "proto 80"

In the above example u used the "prio" qdisc
Can i use this with my htb as the roo qdisc and prio 
lower down in the class?

Thanx

[Soulfly]

I'm happy to help! I just want to make sure you've know the basics so you
don't fall into pitholes. Examples is one of the best sources of
information.

Oh I didn't look up the number for your protocol, so exchange the 'XX' with
this.

I have a configuration which use 5 prio levels (2 above the standard
priolevels). I conerted it to 4 and forgot to alter the band parameter.. so
the correct line is..

tc qdisc add dev eth0 root handle 1: prio bands 4 priomap 2 3 2 2 3 3 3 3 1
1 1 1 2 2 2 2

Yes, this should work out well. I suggest you add prio qdisc to the leafs in
your htb class-tree.

Yes, you can add the prio qdisc on a htb class.

Re: [LARTC] An example of prio qdisc please...

[Tobias Geiger]

correct me if im wrong, but couldn't u achieve the same goal only with htb?

i mean by creating a leave-level with classes rate^[ps, ceil=maxbw, prio 0-6

and attaching sfq/pfifo as leave-qdiscs to these classes?

s.th. like:
tc qdisc root handle 1:0 htb
tc class parent 1:0 handle 1:1 rate <maxuploadbw>
tc class parent 1:1 handle 1:10 rate 1bps ceil <maxuploadbw> prio 0
tc class parent 1:1 handle 1:11 rate .... ... ..             prio 1
and so on
tc qdisc parent 1:10 handle 10:0 pfifo/sfq
tc qdisc parent 1:11 handle 11:0 ....
and so on
tc filter 1:0 protocol ip prio 0 handle 9999 fw classid 1:10
(syntax is not correct :)
and/or other filters

doesn't do this setup the same as the priomap (in general)?

Greetings

Yes and it's even better.  With cbq you can give the all classes a minimum 
bandwidth so one class can not kill an other by using all bandwidth.  With 
prio, you can generate a lot of traffic in the highest band so the other 
bands have no bandwidth left.

It's not the same, but you can get the same result.
Remember, prio is only for excess bandidth.  So each class will get's at least 
his rate and the class with the lowest prio will get the remaining bandwidth.

Here is my net config:



LAN1->(eth1)ipsec_gw1(ppp0)---------------(ppp0)ipsec_gw2(eth1)<-LAN2
                                                    ^
						    |
						 server

Ok, so I tried this:

tc qdisc del dev ppp0 root
tc qdisc add dev ppp0 root handle 1: prio
tc qdisc add dev ppp0 parent 1:1 handle 10: sfq perturb 10
tc qdisc add dev ppp0 parent 1:2 handle 20: sfq perturb 10
tc qdisc add dev ppp0 parent 1:3 handle 30: sfq perturb 10
tc filter add dev ppp0 protocol ip parent 1: prio 10 u32 match ip
protocol 0x50 0xff flowid 1:1


I did it on my too ipsec-end gateway


so if from I connect from LAN1 to LAN2 via ssh, all traffic go in 10:, 
and when I ftp from LAN1 to the server directly through internet (no
tunnel), traffic go in 30:


But this doesn't change anything, ssh is as slow as without prio when I
do ftp????

Where is my probably qos conception error??

Thanks for any help.
