QoS help needed

[DallasBPF]

Ok, heres the thing, I have set up QoS on our Main router to set QoS going out to 3 different sites (we are using MPLS). Below is the config in Dallas

!
class-map match-any voice-traffic-acl
match access-group 105
match access-group 106
match access-group 107
class-map match-all voice-traffic
match class-map voice-traffic-acl
match dscp ef
class-map match-all voice-signal
match class-map voice-traffic-acl
match dscp cs3
!
!
policy-map Dallas_Corp-VoIP
class voice-traffic
priority percent 10
class voice-signal
bandwidth percent 2
class class-default
fair-queue

I must not be seeing something...where is the question?

 

[DallasBPF]

It's not matching anything;

Can't figure out whats wrong with the configuration, since it doesnt seem to be doing what it is suppose to.

[DallasBPF]

Yes.... I completely forgot to put the question in there lol!

Sooo the problem I am having as stated above is that the config does not seem to be working.... as in the above post I bolded a section where it shows that no packets are being matched. Anyone see any issues with the config?

[BuckWeet]

Its because you are doing a match-all condition..

class-map match-all voice-traffic
match class-map voice-traffic-acl
match dscp ef
class-map match-all voice-signal
match class-map voice-traffic-acl
match dscp cs3


most likley your end stations aren't setting dscp bits(or are being rewritten by your switches)


Verify the bits are being set..

 

[DallasBPF]

I will double check the voice-traffic settings, but I did check the signaling and it is being set to cs3.

[lerdalt]

try posting your input config...are you marking/remarking anything yourself?

 

[DallasBPF]

Everything related to QoS on that router is already posted. Nothing is being remarked, since all has been marked on the switches (we are using AutoQoS)

[lerdalt]

I usually then dig out wireshark to make certain the packets are really getting marked as I expect them to. I've had a couple of instances where things weren't getting classified/marked as I had expected they should.

 

[Minue]

Hello
Why don't you try the "match-any".The "match-all" is tricky and should be avoid,till you have a good understanding of the packets behavior.
Regards

 

[DallasBPF]

class-map match-any voice-traffic-acl
match access-group 105
match access-group 106
match access-group 107
class-map match-all voice-traffic
match class-map voice-traffic-acl
match dscp ef
class-map match-all voice-signal
match class-map voice-traffic-acl
match dscp cs3


Well if I do the 'match-any' on the voice-traffic and voice-signal class-maps, then basically I will be bleeding signaling and rtp traffic into both class-maps.

Meaning with the match class-map voice-traffic-acl being in both class-maps then it will match in both with out defining if it is EF or CS3 traffic. Unless I have a complete misunderstanding going on here?

[Minue]

The idea was for testing. To get some hits on the traffic,to see the behavior.Then you can get more accurate once you know the traffic behavior.I will bet no traffic is being mark because of the match-all statement.
Regards

 

[DallasBPF]

Will give it a shot.

Sorry, I am just very anal about this specific router and just 'testing' things due to it being our Hub router for our MPLS for the entire network is all.

[lerdalt]

You might want to try getting a little less restrictive on the ACL too. Match only the DSCP values and see if you get any matches.

Just a thought.

 

[DallasBPF]

Still no matching done when i removed the below from both of the class-maps voice-traffic and voice-signal;

match class-map voice-traffic-acl



Anyone have any idea what auto qos is setting the dscp and cos values to for voice traffic and voice signaling?

I was under the impression that it was dscp ef and cs3, below is the output from one of the switches with autoqos on it;

Hello
This is much easier than you think.Alway troubleshoot in stages.First blow away your present QOS.Then do a simple class-map.Apply it to see if "ef" traffic is passing throw the router.(You can do the same for cs3).If know hits check the switch or ip phones.

class-map match-any voice-traffic
match dscp ef

[uzumaki]

What kind of equipment are you using for your voice traffic? Cisco Call manager or Avaya?

Are IP phones connected directly to the switch?
and do you have workstations connected to the phone that is then connected to the switch?

What's the output from a show autoqos and running configuration from one of the ports.
