Marking and remarking of incoming traffic
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

Asterisk server and DSCP QOS
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...

IPQoS
Real networks use either PREC (as it maps 1:1 to 802.1p and MPLS TC) or DSCP. Interactive SSH uses PREC 0x0, which is just best-effort and DSCP 0x4 which has no standard meaning (found network where DSCP 0x4 was dropped, completely, as it didn't hit any defined/allowed QoS class, obviously misconfig, BE class should eat anything not already defined) Should interactive...

DSCP marking at core
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...

Problem: DSCP target
Hello everybody, I have tried several iptables versions (from 1.2.4 to 1.2.6a) to mark outgoing packets (change the DSCP field) with no success. #iptables -A OUTPUT -t mangle -d 10.0.0.3 -j DSCP --set-dscp 0x2 iptables v1.2.6a: unknown arg ''--set-dscp'' TOS target is working fine, but I want to create different codes for EF and AF classes in a diffserv architecture.

[Bug 3634] New: IPQoS default should be changed to "none"
...m Created attachment 3760 --> https://bugzilla.mindrot.org/attachment.cgi?id=3760&action=edit IPQoS none patch In this trouble ticket, I propose to change the default value of IPQoS option to "none none?. A patch is attached. - Problem description Starting with OpenSSH 7.8, the DSCP value for packets sent by OpenSSH has changed to AF21 (interactive) /CS1 (bulk) [1]. After this change, there have been numerous reports of poor OpenSSH performance [2]. The cause of this problem is that some networks enforce various restrictions (rate-limiter or policer) on some DSCP traffic and...

DSCP, ToS and Egress
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 ho...

Unable to match/classify non-icmp traffic with TOS bigger than 0x10
This problem is driving nuts, so I am seeking help here. Your help will be deeply appreciated. I have made myself a Linux bridge with eth1 and eth0 to form br0. Then I run a script to configure tc with htb on it. But I can never match non-icmp traffic ( such as tcp and udp ) with TOS or DSCP values such as 0x68. The full story as follows :- 1. On the source testing machine, I do this to set the tos and dscp settings :- (A) iptables -t mangle -A OUTPUT -j TOS --set-tos 0x10 ( to make ssh tos value 0x10 ) or (B) iptables -t mangle -A OUTPUT -j...

TOS Settings to DSCP
I am assuming that the TOS values directly map to DSCP values in the ip header. Is this a correct assumption? If so, can someone tell me the correct setting to set call control packets with a DSCP of AF31(011010) and media with EF(101110)? So would the setting for AF be TOS=46?? Is it possible to mark the media and call control separately?? ---...

RTP/SIP traffic prioritization and Linux issues
Hello, all. I've stumbled across what seems to be a traffic prioritization issue in a Linux environment and wonder if anyone else has encountered or addressed this issue. We had planned to use expedited forwarding for our RTP and perhaps our SIP packets. Our plan was to set DSCP to 101110 (by the way, I think document http://www.voip-info.org/wiki/view/snom+360 is in error as I'm almost certain the expedited forwarding bits are 101110 and not 100010). However, we realized that when these passed through Linux based routers or firewalls using the default pfifo_fast packe...
