Hi,
here I have another newcomer question :-)
in the section 9.6.1 of this how too
http://tldp.org/HOWTO/Adv-Routing-HOWTO/lartc.qdisc.filters.html
we can read commands about filters :
------------------------------------------
# tc filter add dev eth0 protocol ip parent 10: prio 1 u32 match \
ip dport 22 0xffff flowid 10:1
# tc filter add dev eth0 protocol ip parent 10: prio 1 u32 match \
ip sport 80 0xffff flowid 10:1
# tc filter add dev eth0 protocol ip parent 10: prio 2 flowid 10:2
What does this say? It says: attach to eth0, node 10: a priority 1
u32
filter that matches on IP destination port 22 *exactly* and send
it to
band 10:1. And it then repeats the same for source port 80. The last
command says that anything unmatched so far should go to band
10:2, the
next-highest priority.
------------------------------------------
i try to do this at home as i want my ssh traffic prioritary to other
traffic but the problem is with the last command ! it simply don't
work.
The last command that says default trafic goes to prio 2 doesn't work
# tc filter add dev eth0 protocol ip parent 10: prio 2 flowid 10:2
just give me the error: "Unknown filter flowid, hence option 1:2 is
unparsable"
So I don't get what do I must do in order to say that the default
trafic
goes on priority 2 of the prio filter
is this how too always valid with the current version of tc ? did
i do
something wrong ?
Thank you for your help.

You should have posted *all* your tc rules.

Ok, thanks for you advise, here are all my tc rules :
# tc qdisc add dev eth0 root handle 1: prio
# tc filter add dev eth0 protocol ip parent 1: prio 1 u32 match ip
dport 22 0xffff flowid 1:1
# tc filter add dev eth0 protocol ip parent 1: prio 2 flowid 1:2

does this lack one rule ? anyway the last one is not accepted by tc.
Vincent.
