I have thr same problem with a similar ppc based = processor (the MPC8245).
I tried to resolve the problem for three months = without any result.
I noticed that the problem should be in the filters = and that the behaviour is different if the traffic is local (to the = router box) or to be forwarded.

Any idea?

Oggetto: Re: [LARTC] [Q]About Using TC in = MPC8250


MPC8250 is a CPU name produced by Motorola.
It is a kind of Motorola PowerPC processor. Linux = can run on the MPC8250.

Every kernel functions regarding to TC CBQ looks = working -
I followed the CBQ kernel code step by step and = found no problems.
But the bandwidth I allocated is not guaranteed. =

I think it is related to CPU characteristics,
but I don't have any specific knowledge about = it.

I don't think the script is wrong, 'cause I used that = script for other
linux (running on normal i386 machine) and it works = good.

Anyway here is a script.

--

/sbin/tc qdisc del dev eth1 root handle 1:

/sbin/tc qdisc add dev eth1 root handle 1: cbq = bandwidth 102400Kbit avpkt 1500 cell 8

/sbin/tc class add dev eth1 parent 1: classid 1:2 cbq = bandwidth 102400Kbit rate 102Kbit allot 1514 cell 8 weight 10Kbit prio = 3 maxburst 16 avpkt 1500 bounded

/sbin/tc filter add dev eth1 parent 1: protocol ip = prio 3 u32 match ip src 10.0.10.72 match ip dst 10.0.0.47 flowid = 1:2
