Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using.
The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS 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

I think all the filters below here should be on 2:0

Hi, thx for the reply. If I changed the parent to 2.0 for the filters this would not pass the minor classid field back to the tcindex, which is required for gred?
thx jason
