similar to: DSCP marking at core

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 folks I have created a script file (dsmark+policing.sh attached) to check graphic an text outputs of simutations, against original examples/dsmark+policing coding (see TCNG Reference Manual-pg.90). It uses tcng coding (*.tcsim file attached) and old tc coding (*.tcsim_old file attached) inserted in tcsim files. Observation 1: The graphic outputs from (*.tc included in *.tcsim) and (*.tc_old

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?

I want to set the DSCP at the ingress of the router.

Im experimenting with using a Linux machine with 3 interfaces to operate as a core router. All links and network interfaces are 100mbit. Below is a ascii diagram of the network. (network A) edge router ------>core router---->edge router (network C) ^ | | edge router (network B) I have tried two

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 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

hai all i need to implement CBWFQ in linux As i wrote script in edge as: which mark the EF traffic ____________________________________________________________________-__ #!/bin/sh DEV=eth0 tc qdisc add dev $DEV handle 1: root dsmark indices 8 tc class change dev $DEV classid 1:1 dsmark mask 0x3 value 0xb8 # making two filters tc filter add dev $DEV parent 1:0 prio 4 protocol ip u32 tc

hi all i am a new commer of linux community. i want to how does skb->tcindex value change exactly. it confused me indeed. i have a script reads: (1) tc qdisc add dev eth0 root handle 1:0 dsmark indices 64 default_index 0x161 set_tc_index (2) tc filter add dev eth0 parent 1:0 protocol all prio 1 tcindex mask 0xfc shift 2 pass_on (3) tc filter add dev eth0 parent 1:0 prio 1 handle 0x0a

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

All: I am tasked with creating an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.)

Hi stef and all I want measure the policy perfomance for video traffic on mpls diffserv network. there are two different polices for video packet 1. Video packets that are marked that are over the limit are to be rejected at the edge router. 2. Video packets that are marked that are over the limit are to be downgraded as best effort and are sent through. Before video enter my mpls

Hi i have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets. The cbq is configured at a rate of 500Kbit "qdisc cbq 4: rate 500000bit (bounded,isolated) prio no-transmit Sent 100103048 bytes 73933 pkts (dropped 0, overlimits 0) borrowed 0 overactions 0 avgidle 24000 undertime 0 " The traffic that being generated is more than 5Mbit with the

Hi fellow traffic-shapers, I am implementing a Diffserv CORE router using Linux kernel 2.4.18. I used this excellent website (http://www.opalsoft.net/qos/DS-38.htm) using AFHTB as a starting basis for my EGRESS diffserv implementation - and all works great so far!!! But my project has an additional requirement. There are services running locally on the router which are sending/receiving IP

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

Hello! I have some trouble with dsmark qdisc. I''d like to set DSCP value of my outgoing packets and add a rate limit to each one. I learned HTB and dsmark. They work properly, but I can''t combine them like this: tc qdisc add DSMARK handle 1:0 ... tc class modify 1:1 ... tc class modify 2:2 ... ... tc qdsic add parent 1:1 HTB ... tc qdsic add parent 1:2 HTB ... ->
