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.

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)

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 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.
Any help would be ap...

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...

I found one post that says to run at boot:

Does this make sense? Is this the only method to end ths warning?

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...

Can't match DSCP CS6 and CS7
Hi,
DSCP match in /tcrules/ doesn''t work with CS6 and CS7, it provides an
error "invalid value" for string and hexa values.
It seems that it comes from /Chain.pm/, in the function /do_dscp/:

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...
