[LARTC] CBQ,... RTNETLINK: Invalid Argument

[Paul Robinson]

Hi all,

I've got a problem i cant seem to find a way around... i've read the
Advanced Routing HOWTO, and im trying to setup (what i thought) would be a
simple bandwidth management scenario to limit trafic to a machine (1.2.3.4)
on the local lan to about 3K.

however... heres what im trying to do (follows the howto fairly closely)

-----
tc qdisc add dev eth0 root handle 1: cbq bandwidth 100Mbit avpkt 1000

tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 100Mbit rate
100Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000

tc class add dev eth0 parent 1:1 classid 1:2 cbq bandwidth 100Mbit rate
3Kbit allot 1514 weight 1Kbit prio 5 maxburst 20 avpkt 1000 bounded

tc qdisc add dev eth0 parent 1:2 sfq quantum 1514b perturb 15

tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst
1.2.3.4 flowid 1:2
-----

All works fine until the last statement;
# tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst
1.2.3.4 flowid 1:2
RTNETLINK answers: Invalid argument
#

Have i missed something obvious? or is something missing from my kernel??

Im running with kernel 2.4.0.

Regards, Paul

Please send your .config file. Also, there have been reports of problems
that go away when upgrading to the newest version of tc, as found in the
iproute2 package. The howto tells you where to find the newest versions.
