Try
tc filter show dev eth0
tc class show dev eth0
tc qdisc show dev eth0

Ok, I tried a kernel with CONFIG_NETLINK_DEV compiled in and the tc from
iproute2-2.4.7-now-ss020116-try.tar.gz but I still can't see any entries in
the class or filter list. After adding these rules:

< snip <--< snip <--< snip <
tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 1000 \
mpu 64

tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 10Mbit \
allot 1514 cell 8 weight 1Mbit prio 8 maxburst 20 avpkt 1000

tc class add dev eth0 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 3Mbit \
allot 1514 cell 8 weight 100Kbit prio 3 maxburst 20 avpkt 1000 split 1:0

tc class add dev eth0 parent 1:1 classid 1:3 cbq bandwidth 10Mbit rate 8Mbit \
allot 1514 cell 8 weight 800Kbit prio 7 maxburst 20 avpkt 1000 split 1:0

tc filter add dev eth0 parent 1:0 protocol ip prio 100 route
< snip <--< snip <--< snip <

I get:

< snip <--< snip <--< snip <
root@rana:~# tc filter show
root@rana:~# tc class show
root@rana:~# tc qdisc show
qdisc cbq 1: dev eth0 rate 10Mbit (bounded,isolated) prio no-transmit
root@rana:~#
< snip <--< snip <--< snip <

As you can see the qdisc is added, but the class and filter entries don't
seem to work.

If I type the same filter rule multiple times, it allows it so I don't think
it is added at all. The class entries seem to be added because I get EEXIST
if I add the same rule multiple times, but it does not show up in ``tc class
show'' - any ideas?

The latest version is iproute2-2.4.7-now-ss020116.  I recommend using it.

From your attached config :
# CONFIG_NETLINK_DEV is not set
I suggest enabling it and try again.

[LARTC] tc { class | filter } does not work

[Abraham van der Merwe]

Hi!

I'm trying to use tc on linux 2.4.20-rc1aa with iproute 20010824-8 (latest
debian package), but I'm having no joy.

I can add queueing disciplines, but when I try to add classes or filters, I
just get "RTNETLINK answers: Invalid argument", e.g. when I try to do:

< snip <--< snip <--< snip <
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 1000 mpu 64
< snip <--< snip <--< snip <

it works fine and I can see the queueing discipline when I type ``tc qdisc
show'', but when I do:

< snip <--< snip <--< snip <
tc class add dev eth0 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 3Mbit \
allot 1514 cell 8 weight 100Kbit prio 3 maxburst 20 avpkt 1000 split 1:0
< snip <--< snip <--< snip <

or

< snip <--< snip <--< snip <
tc class add dev eth0 parent 1:1 classid 1:3 cbq bandwidth 10Mbit rate 8Mbit \
allot 1514 cell 8 weight 800Kbit prio 7 maxburst 20 avpkt 1000 split 1:0
< snip <--< snip <--< snip <

I just get the EINVAL error message. Filters also does not seem to work. I
can add route filters, but ``tc filter show'' shows nothing and adding u32
filters fail with the same error messages as the classes.

I've attached my kernel config in case you want to check whether I
configured the correct stuff (but I pretty much enabled everything - the
only odd thing is that I couldn't configure CONFIG_RTNETLINK and
CONFIG_NETLINK into the kernel since those options are not available anymore
(selected by default nowadays?))

Any help would be appreciated.
