I have been working on this problem and have tried MANY different things to get it working. So let me recap as best I can. I have the following configuration working fine: uClibc 0.9.26 built Linux 2.4.22 kernel system with iproute2-2.4.7-now-ss010824 and bridge-utils-0.9.6. When I move to Kernel 2.4.25 the tc shaping on the bridge interface does not work. It stops all ip traffic. If I setup the bridge and bind the ip to an Ethernet interface and run tc on that it works. I guess what I need is the correct patches to apply against an iproute2 package with a 2.4.25 Kernel. Can someone kick me some links?

The things you say seem partly contradictory, and it is really not clear what is the problem - however, I will give an example of what things do on *my* system so you can spot the discrepancy between your systems. ,---- | ... no configuration ... | shiro:~# ip link show dev eth0 | 7: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100 | link/ether 00:30:1b:ae:6a:66 brd ff:ff:ff:ff:ff:ff | shiro:~# tc qdisc show dev eth0 | qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] | shiro:~# tc class show dev eth0 | shiro:~# tc filter show dev eth0 | | ... add a qdisc ... | shiro:~# tc qdisc add dev eth0 root pfifo limit 100 | | ... show configuration again ... | shiro:~# ip link show eth0 | 7: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo qlen 100 | link/ether 00:30:1b:ae:6a:66 brd ff:ff:ff:ff:ff:ff | shiro:~# tc qdisc show dev eth0 | qdisc pfifo 8002: limit 100p | shiro:~# tc class show dev eth0 | shiro:~# tc filter show dev eth0 `---- And no loss of connectivity to anywhere, or anything of the likes. If this does not work for you, then there is something seriously wrong either with your kernel or with tc. If this does work for you, I suggest specifying exactly what you commands you are saying that cause your problems - there might be something wrong there. -- Naked _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
