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

I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would seem ideal as most networks still honor it to varying

I''m trying to configure dsmark qdisc on 2.6.11.4 user mode linux and tc from iproute2-2.6.11-050314. I think I have some mismatch in my setup since adding dsmark qdisc fails *unless* I specify "set_tc_index" argument which I believe should be optional: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 RTNETLINK answers: Invalid argument Mar 20 13:00:50 user user.debug

Hi all! Anyone got the same problem? If I: tc qdisc add dev eth0 handle 1:0 root dsmark indices 4 set_tc_index it works fine. If I: tc qdisc add dev eth0 handle 1:0 root dsmark indices 4 it says: RTNETLINK answers: Invalid argument I just don''t need that set_tc_index stuff for marking.

I want to set the DSCP field of the incoming packets. And then put them in the correct queues. I can mark the packets: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle 1:0 dsmark indices 64 set_tc_index tc class change dev eth0 classid 1:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent 1:1 protocol ip prio 1 handle 1 fw

Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

Hi, I want to setup core routers to do both DSCP marking and to get the DSCP and forward packets based on DS field. I don''t want to separate DSCP marking to be done only at the edge routers. I know that dsmark is both used for DSCP marking and for getting the DSCP and forwarding packets according to DSCPs. In my case, since I want to do both of these I need two dsmarks.(?) I am not

Hi! I am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers?

I can use DSMARK to mark on the Egress side. Is there a way to mark/change the DSCP value of an incoming packet on the ingress side? Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

I want to set the DSCP at the ingress of the router. I tried the following: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle ffff:0 ingress dsmark indices 64 set_tc_index tc class change dev eth0 classid ffff:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent ffff:1 protocol ip prio 1 handle 1 fw classid ffff:1 But the DSCP

Im using a Linux machine with standard pc hardware with 3 seperate PCI network interfaces to operate as a DiffServ core router using Linux traffic control. The machine is a P4 2.8ghz, 512mb RAM running fedora core 3 with the 2.6.12.3 kernel. All links and network interfaces are full duplex fast ethernet. IP forwarding is enabled in the kernel. All hosts on the network have their time sychronised

Hi all! In short: Anybody wrote a patch for DSMARK to make it capable of marking only a ratio (a given arg to the tc command) of the packets it gets? Say, 20%? Or, do I have to hack into the source? Alternatives, like a filter spitting packets to 2 different DSMARK based on this ratio? In long: I''m a hungarian univ student involved in a project (RMD-QoS stuff) which needs

Hello, I have the following proplem. My DiffServ configuration is working fine when I do ping, but when I use mgen the packets are not detected at the core router. Here is my core router configuration: #!/bin/bash tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index tc filter add dev eth1 parent 1:0 protocol ip prio 1 tcindex mask 0xfc shift 2 tc qdisc add dev eth1 parent

Hello! In our experiment, we are trying to mark IP packets at a source host. Some of these packets have a 28-byte "IP Options" field, hence a 48-byte IP header. We observed (using ethereal) that the tc script at the source appropriately marks the packets that DO NOT have an "IP Options" field (i.e., regular 20 byte header), however, all the packets with the "IP

Can anyone comment on the DSCP quality of service settings on your Asterisk server? The network we're setting up has data on the default VLAN, Asterisk server and phones on VLAN 4, and we're using Polycom phones with a PC hooked up to the phone's pass-thru port. What iptables settings are you using on the Asterisk server for DSCP? What are your Polycom DSCP settings? We're using
