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 On Tue, Apr 22, 2003 at 01:26:18PM +0200, Stef Coene wrote: > On Tuesday 22 April 2003 13:18, soyoung@xxxxxxxxxxxxxxx wrote: > > Hi, > > > > I'm running Linux 2.4.17 on MPC8250 CPU for bandwidth management with TC > > CBQ.
