Can somebody tell me what's wrong in this script?   I'm a begginer in traffic shaping and I can't figure it out

#!/bin/sh
 
DEV="dev eth1"
 
tc qdisc del $DEV root
tc qdisc add $DEV root handle 10: prio
tc qdisc add $DEV parent 10:1 handle 20: est 1sec 8sec
bfifo
tc qdisc add $DEV parent 10:2 handle 30: est 1sec 8sec
bfifo
tc qdisc add $DEV parent 10:3 handle 40: est 1sec 8sec
bfifo
 
tc filter add $DEV parent 10: protocol ip prio 1 u32
match ip tos 0x10 0xff flowid 10:1
tc filter add $DEV parent 10: protocol ip prio 1 u32
match ip tos 0x06 0xff flowid 10:2
tc filter add $DEV parent 10: protocol ip prio 1 u32
match ip tos 0x0c 0xff flowid 10:3











                                                                                                        Thanks a lot
                                                                                                        alexCOS

But what's the problem?  Is it not working?  Do you get any errors if you 
execute this script?

Yes..  this is the error part:


[root@alexcos root]# tc qdisc del dev eth1 root
[root@alexcos root]# tc qdisc add dev eth1 root handle 10: prio
[root@alexcos root]# tc qdisc add dev eth1 parent 10:1 handle 20:est 1sec 8
sec bfifo
Unknown qdisc "1sec", hence option "8" is unparsable
[root@alexcos root]# tc qdisc add dev eth1 parent 10:1 handle 20:est 1 sec 8
sec bfifo
Unknown qdisc "1", hence option "sec" is unparsable






Full source script:

tc qdisc del $DEV root
tc qdisc add $DEV root handle 10: prio
tc qdisc add $DEV parent 10:1 handle 20: est 1sec 8sec
bfifo
tc qdisc add $DEV parent 10:2 handle 30: est 1sec 8sec
bfifo
tc qdisc add $DEV parent 10:3 handle 40: est 1sec 8sec
bfifo

tc filter add $DEV parent 10: protocol ip prio 1 u32
match ip tos 0x10 0xff flowid 10:1
tc filter add $DEV parent 10: protocol ip prio 1 u32
match ip tos 0x06 0xff flowid 10:2
tc filter add $DEV parent 10: protocol ip prio 1 u32
match ip tos 0x0c 0xff flowid 10:3

I don't know the syntac for the bfifo qdisc.  But what if you simple remove 
some parameters :
tc qdisc add dev eth1 parent 10:1 handle 20: bfifo

Re: [LARTC] Script problem

[Alexandru Coseru]

it worked...  thanks..

I'm gonna test it later to see if it really works & shapes the traffic..


One more question though ...

    Can I add more than 3 (three) bands ?


Like:

tc qdisc add dev eth1 parent 10:1 handle 20:bfifo
tc qdisc add dev eth1 parent 10:2 handle 30:bfifo
tc qdisc add dev eth1 parent 10:3 handle 40:bfifo
tc qdisc add dev eth1 parent 10:4 handle 50:bfifo


of course , i get an error at the last line...  but can I do it in another
way ?


                                                Thanks

Alex

Isn't there an option if you add the prio qdisc to specify the number of 
bands?

Yes.

<snipped>

9.5.3.1. PRIO parameters & usage

The following parameters are recognized by tc:

bands

    Number of bands to create. Each band is in fact a class. If you change
    this number, you must also change:
