...parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it does not work? Any suggestion appreciated. thx jason 1. The DS field is marked by iptables in prerouting/mangle to the appropriate class. 2. DSMark masks the ds and copies ths dscp to the tcindex field. 3. filters are selected as per what dscp there handle is. 4. the minor of the filter is returned back to the dsmark and copied to the tcindex #!/bin/sh tc qdisc del dev eth0 root tc qdisc add dev eth0 handle 1:0 root dsmark indices 16 set_tc_index tc filter add dev eth0 parent 1:0...

Hi: Execuse me if this has been mentioned before, I''ve looked around the archive but did not find anything about the problem I met. I''m trying to use tcindex to classify the the packet outgoing to one interface. I do as the following : tc q a dev eth0 root handle 10:0 cbq bandwidth 10Mbit avpkt 1500 tc c a dev eth0 parent 10:0 classid 10:1 cbq bandwidth 10Mbit rate 10Mbit maxburst 50 avpkt 1500 tc c a dev eth0 parent 10:1 classid 10:100 cbq ba...

...netlink socket with a user process, read the tc netlink messages generated by the tc process and parse them. What I see is that the kernel has already processed the messages (i.e., adds some default values for example) before making them available to my process. Problem comes when I parse the tcindex messages. Here is an excerpt from the examples in iproute2 diffserv distribution. $TC qdisc add $EGDEV handle 2:0 root dsmark indices 64 # # The class mapping # $TC filter add $EGDEV parent 2:0 protocol ip prio 1 \ handle 1 tcindex classid 2:1 $TC filter add $EGDEV parent 2:0 protocol...

Hi all, I''m trying to get some DiffServ QoS shaping to work on an XScale machine, running big endian. I''m setting it up with tc. Using the tcindex filter I found that regardless what shift value I enter, only ''0'' is returned when I list the filters afterwards. The very same rules work fine on my (little endian) PC. Looking at the code (iproute2-2.6.18-061002) I found that tc (in tc/f_tcindex.c, line 72 and after) sends th...
