similar to: Marking packets with IP Options field

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

Dear all can anyone tell me how to mark packet''s DSCP value using tc? Thanks.

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

Did anyone ever answer this one?

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

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

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

Hy, I would want to mark the packets that are entering in a machine, with a mark for using diffserv with DSMARK. My machine has 2 interfaces, a ethernet and a wireless. The ethernet interface is eth1 and the other is wifi0. Firs, I would want to test that I would be able to mark the tos of the paquets that I would be receiving, for this I write in the console of my linux: iptables -A

Hi, I am trying to implement a simple scaled-down version of the AF traffic class type. As such I basically want to remark non-conforming AF11 packets to AF13. Here is m script that I have been using on the ingress router of my network: ---------------------------------------- Link=''dev eth1'' Rate1=''rate 800Kbit'' Rate2=''rate 2500Kbit''

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

I ''m having a problem identical to one encountered on this list awhile back: >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:

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

Hi all, Another requirement we have is that traffic entering the DS domain be classified then subsequently assigned a (different?) DSCP based upon its classification. For illustrative purposes only let''s say (for traffic entering the DS domain on dev eth0): - WWW traffic would be marked BE - traffic destined for 10.10.10.10 would be marked AF11 - VoIP traffic from 20.20.20.20 would

Hello - What I want to do seems very simple - I want to make sure any H.323 traffic gets processed before anything else entering or leaving this network. The network has a videoconferencing device on the LAN at 192.168.16.4. A Linux firewall NATs an external IP Address to this internal address and I have appropriate SNAT and DNAT rules that work. The NAT and connection tracking rules all work

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, Supposedly my router is itself streaming traffic to clients. Is it possible for it to mark its packets before going through dsmark?? I have gone through the examples in iproute2/examples, i noticed that there''s always an ingress and egress of which these are 2 different dev. Is it possible for before ingress and egress be the same dev?? I tried the script below but

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

Hi, I want to use the dsmark, but it always says: "unkown qdisc", although I have enabled it (y in Network options), and I have my kernel recompiled. I am using SuSE 8.1, 2.4.20 Kernel, tc available at the HTB site (with already precompiled HTB queue). Can anybody find the problem? thx _________________________________________________________________ MSN 8 helps eliminate e-mail

Hello! What is the significance of "handle" in a u32 filter?? For example, if I have a HTB class 1:1 and three child classes 1:11, 1:12, and 1:13. Within 1:11, I define dsmark, say 2:0, and let it mark packets with certain DSCP. Now, using the u32 filter I need to classify packets of a certain flow (e.g., based on src ip address and dest port), then can someone give me an example of

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.
