QoS Setting
Hello There,
I was wondering if anybody could tell me how to set up QoS on WRVS 4400N, because when I try set it up on download and upload bandwidth there are nothing changes in traffic connection in fact my bandwidth become smaller.
Btw my connection from ISP
DL 6 MBps
UL 1,5 MBps.
Thank
Cablak,
Remember that you will only be able to control the traffic while it is on your equipment, once it leaves your network it is up to the ISP's to priorities the traffic how they want. You could police the traffic meaning when you are receiving traffic on the WAN when it is being placed into the buffers it would allow some types of traffic through with little to no buffer and buffer other traffic if needed due to the speed of the LAN, However usually the bandwidth coming in from the ISP in your case 6Mbps is much slower than the LAN at a minimum of 10Mbps usually 100 or 1000Mbps. There should be no reason why traffic is being held up getting onto your network.
The traffic going to the Internet you could QoS and shape the traffic as it leaves your network, for you 100Mbps to 1,5Mbps. You could give lets say voice traffic 512Kbps guaranty and the rest of the bandwidth to other forms of data, but you will need to do research on your traffic. If you set a protocols priority too low it might cause packet retransmission if it is TCP and cause more bandwidth being taken up vs less. Also if it is UDP traffic it might be dropped completly and stop working.
Make sure you are manually changing your Up and Down to match what you are getting from the ISP. Also remember if you priorities lets say voice over Data then you will see slower speed tests because you told it to.
I don't know your settings, or the type of traffic you have on your network, to know why you are seeing the results you are seeing but I hope this helps,

ACE module - Qos - set ip tos #
All,
Trying to mark traffic to/from L4 rules in the ACE.
Documentation (like always) says it's really easy. Mark traffic by using the "set ip tos <value>" command in Policy/Class configuration. Ok, so I do this, set ip tos 24.
Enable qos globally on the 6500 host, but don't see the traffic being marked.
sh mls qos says that packets are being modified by module 5 (ACE)
But I never see the tos value in any of my captures either via netflow from the host 6500, or at the firewall one hop away.
sh mls qos:
QoS is enabled globally
Policy marking depends on port_trust

Can someone explain to me what I've got wrong here? Is the ACE simply marking traffic destined for the servers behind it and not the return traffic? Am I missunderstanding something?Well... hopefully someone knows how to classify traffic coming from the ACE.
I've given up on using the ACE to mark traffic as I'm fairly certain it won't do it. At least not the way I want.
However, now I've taken to marking ingress on the rserver switch ports... which has resulted in a partially sucessful solution. Problem is, "partially" successful.
You'll have a bunch of little conversations like this with no tos value full of push-acks:

I think what's happening, is that the conversations full of the P-acks is the load balancer communicating directly with the client (i.e. LB pretending to be the server), whereas the marked traffic is "data only" which the load balancer isn't mangling (like it might/probably is doing with the p-acks) on it's way back to the client.
I also can't modify the configuration of the "virtual ten gig" interface that the 6500 uses as a connection to the ACE module, so can't mark traffic there either. And though I still have a couple of things to try, I don't believe I can do egress marking on a trunk from the 6500 either (connection to the firewalls).
So.... PLEASE... Anyone??? Ideas??? -
NMH405 and QOS setting on Router to optimize network traffic
Are there settings to optimize the NMH405 on a Network. I'm using a Westell DSL Wireless 4 port Modem/Router with QOS options.
It seems that there is a lot of lag time now when I try to move and read files to or on the NMH405. If adjusting my router to work well with the NMH405 will help through basic or advanced funtions I'm willing to do that. This could also help when using the SONY Playstation 3 to access music and photos.
All the best,

Hyper-V 2012 R2 QoS for a specific set of VMs?
I'm trying to figure out how to setup SCVMM 2012 R2 with a Logical Switch to support QoS for a specific set up VMs. Specifically, I have a subnet that will have a variety of VMs running, but within that subnet I have a handful of VMs that need a unique
software QoS setting. Is this possible?

Setting up Cisco SLM248GT-NA switch for VoIP
Hello Everyone,
We have a Cisco slm248gt-na smart switch in our office that I am trying to configure to support and optimize for VoIP. We have desktops hooked up off the phones in most cases. Are there any config guidelines to optimize the switch so it has proper QOS set and VoIP gets higher priority over data.
Thanks, Kind Regards
ShabbirHello Tom,
Thanks for your reply.
We have a pretty straight forward setup. We have 15 Cisco SPA303 phones hooked up to switch and the desktop are connoted via the phone. We have a wireless LAN and a corporate server that servers as a file sharing/vpn type setup. Other than that there are no devices hooked up. We had to implement auto voice vlan feature but were still running into issues like occasional poor voice quality and one way audio type issues. However I did notice something in the configuration menu "Telephone OUI", could you please help us on how to implement that. We are trying to implement best practice to avoid voip related issues that we have been having.
We also see all the ports in trunk mode. Is that the recommended setting or should we change it to access mode?
Thanks, Kind Regards -
QoS group policy in UCCE 9.0 getting refreshed
Hello,
We upgraded a couple clients onto our HCS environment. Since we have had a couple outages where the A side loses connection with the B side. Normally this is related to some network interruption and it appears that way in the logs. However when I look in the system event viewer on the call server I see the following:
Log Name: System
Source: Tcpip
Date: 2/10/2014 6:39:07 PM
Event ID: 16501
Task Category: None
Level: Information

User: N/A
Computer: USPHXXXXX
Description:
Computer QoS policies successfully refreshed. Policy changes detected.
AND
The Advanced QoS Setting for inbound TCP throughput level successfully refreshed. Setting value is not specified by any QoS policy. Local computer default will be applied.
I can match these up before every outage. As you guys know after 8.5 Cisco switched from packet scheduler based qos to the group policy. So I'm wondering if anyone else has seen this in 9.0. The first time I thought maybe it was coeincedence but since have seen it on other outages on completely seperate instances. The thing I wonder is if this is just an affect of an outage but I see this before is loses connection to the call server's duplexed partner. So believe it may actually be the cause.Yes eventually we did after bringing up the firmware, adapter driver, bios. Here is a chart I made for different C-series. Disregard column 2.

Making sure Qos is working?
Hi All,
This question has probably been asked a million times but I cannot find a solid answer. We had our routers setup by an external company and I'm not sure if they completely finished the Qos settings on the routers. How do I check?
I am new to QoS so bear with me.
Our setup can be seen in the diagram attached.
The user switches are running AutoQos on each port

There is a global QoS config set automatically by AutoQos template.
The Etherchannel-Trunk ports from the user switches to the Core switches and vice versa have the following commands set
mls qos trust dscp
priority-queue out
Q1: What Qos settings need to be added to the core switch? I have no phones are attached to it.
Currently we have the following global Qos values set
mls qos
mls qos map cos-dscp 0 8 16 24 32 46 48 56
Q2: What Qos settings need to be added to the router subinterface ports and global configs.
mls qos is not set globally but there are a bunch of policy-maps and class-maps?

Do I need any class-maps policy-maps set on the Melbourne 3750X-CORE and 3750X switches.
* I am looking at basic Qos rules Voip packets take priority ... leave all other data packets untouched.
Thanks for having a look. Cheers -
QoS Questions for 3750 Switches
2x3750 switches are stacked and we are trying to simulate traffic congestion at the UTP ports by using Smartbit 6000C. The objective of the test is to see if the QoS setting works in reality even though we see from Wireshark that the packets are marked with DSCP for voice traffic.
Setup is as follows :
Smartbit<->Avaya IP Phone<->3750 switches<->6509 switch.
Please note that the configuration is set on the 3750 switch port as well as trusted on the Cat 6 switch port. However, when I set to continuous traffic with byte size of 64. Even though its a 100Mbps port, the Avaya IP Phone is already acting weird with hanged symptom. Just side note is that performing "show mls qos inter gi2/0/7 statistic" shows that data and voice traffic are marked on the different priority which seemed correct.
1) Is this the right way to test? If not, what should be the correct way?
2) The port that's connected to Smartbit is configured and it seemed that with the continuous traffic, even other IP Phones are hanged even though I have set Smartbit to hit on the IP address of the CAT6 Switch port. This is not normal right as this is supposed to be unicast traffic. Any idea what could be the reason?Hello Brandon,
I understand your concern and how you want to test, but with the VoIP services you need to understand that there are 2 points (telephones if you want) involved. Your local one, where you might have taken all the necessary steps to protect and prioritize your voice traffic, and the oposite end which also need to have the voice packets prioritized.
Now, from your description, I understand that the packets (voice and data) marked correctly (I believe on C3750), but that's not enough. You need to use CBWFQ together with LLQ to give priority to the Voice traffic over data in case of congestion. Do you have such configuration? Can you show us some excerpt from it?
Next, during the testing, you said that your phone hang-up...where you in a call?
To respond to your questions:
1. The start is ok, but we need more details. You are pushing traffic from Smarbit, this is your local end, but where is the traffic pushed to (remote end), who is receiving the traffic?
2. In theory, you shouldn't have any impact over voice if links are 100Mbit, only if you have such a power packet generator that could fill 100Mbit. What do you mean by "This is not normal right as this is supposed to be unicast traffic"? VoIP is also unicast traffic...
I can see that you are determined to solve this issue, and this is OK as it will help you back with gained knowledge, but I have to warn you that troubleshooting QoS / Voice related problems may be more tricky than you think, as it will involve a strong know-how in these areas.
We will help, but you have to come back with more precise details.
Good luck!

Hi,
I am trying to mark packets at VAI interfaces and then use this markings to
classify traffic in different classes when they exit the router downstream

So in short the VAI policy is marking packet correctly, IP precedence
accounting shows hits but on the main policy it skips its..
Interestingly if i remove VAI policy and mark the packets from an upstream
router using extended pings they are identified by the physical interface
correctly and matches against appropriate classes.
Any hints will be appreciated.

Logically, what you're doing makes sense, but only Cisco "knows" how their queuing really works. I've long suspected their embedded CBWFQ shapers have their own queues, which you may not have direct control over for setting their queue depths.
Yes, logically, there's a relationship between bandwidth (including shaping) and queue limits, but it depends on multiple factors. Shaping is also a special case, because although you're trying to emulate a certain link bandwidth, it's not the same. -
Hi All,
I have some trouble regarding the QOS implementation for the VOICE communication.
I tried to setup the low latency queuing but it showed that it is weighted fair

I want to apply the strict policy ( reserved the bandwidth) of 128 k for voice.
After this configuration my voice is still not good ( choppy).

WRT600N QoS settings do not affect upstream rates
I have recently purchased a WRT600N router as I have a hard wired wired VoIP phone (Aastra 9112i). I have set the QoS priority for the physical Ethernet port that the phone connects to as high and all of the other ports as normal (I have even tried setting all of the other ports to low).
The problem I have is that the QoS settings do not affect the upstream rate. I have Shaw Highspeed Extreme service and have run speed tests to Speedtest.net throught the router and can get 20Meg down and ~1 meg up. When I change the QoS settings on the physical Ethernet port my laptop is connected to, the QoS settings do affect the download rate but the QoS settings do not seem to affect the upstream rate.
Is there any firmware update for the WRT600N where the QoS setting will control/ throttle the upstream rate or is there some other settings I could use on the WRT600N that will provide priority to my VoIP phone.
Thanks,I just checked the Linksys download page and the firmware version posted there 1.01.35 is the same version I have in my router. Please let me know if there are any development plans for the WRT600N QoS controls so the the QoS setting also police the upstream/ upload rates.
Thanks, -
QoS Override Per-SSID Bandwith question
Hi all,
on a WLAN there is the possibility to override the QoS Bandwidth settings.
I try to get some more information about these settings, I want to understand this. As well a customer wants to limit user data.
My question is: This override Per-SSID, are these settings on a AP basis or on the global controller basis?
The next question resulting out this will then be what if the AP is set to flex-connect with local VLAN traffic, what then?
Is there a good documentation on this?
Thanks.This section describes BDRL of the 7.3 release. In releases 7.2 and earlier, there is only the ability to limit the downstream throughput across an SSID and per user on the Global interface. With this new feature in the 7.3 release, rate limits can be defined on both upstream and downstream traffic, as well as on a per WLAN basis. These rate limits are individually configured. The rate limits can be configured on WLAN directly instead of QoS profiles, which will override profile values.
This new feature adds the ability to define throughput limits for users on their wireless networks with a higher granularity. This ability allows setting a priority service to a particular set of clients. A potential use case for this is in hotspot situations (coffee shops, airports, etc) where a company can offer a free low-throughput service to everyone, and charge users for a high-throughput service.
Note: The enforcement of the rate limits are done on both the controller and AP.
Rate limiting is supported for APs in Local and FlexConnect mode (both Central and Local switching).
When the controller is connected and central switching is used the controller will handle the downstream enforcement of per-client rate limit only.
The AP will always handle the enforcement of the upstream traffic and per-SSID rate limit for downstream traffic.
For the locally switched environment, both upstream and downstream rate limits will be enforced on the AP. The enforcement on the AP will take place in the dot11 driver. This is where the current classification exists.
In both directions, per-client rate limit is applied/checked first and per-SSID rate limit is applied/checked second.
The WLAN rate limiting will always supercede the Global QoS setting for WLAN and user.
Rate limiting only works for TCP and UDP traffic. Other types of traffic (IPSec, GRE, ICMP, CAPWAP, etc) cannot be limited.
Only policing is implemented in the 7.3 releases.

I'm pretty sure I know the answer to this but I'm checking here as well.
With a Cisco WISM2, is it possible to have only voice set up for QoS? I'm not talking about having a dedicated SSID set up for wireless voice with QoS set to Platinum, but a generic SSID that will identify voice traffic and apply the correct QoS settings?
From what I've seen it's not possible. The reason I ask is we want to install softphones on our tablets and use our existing wireless network to be able to use wireless voice. However, it looks like if we set the QoS on that SSID to Platinum then ALL data on that SSID gets marked as high priority, not just voice traffic.
Am I correct?The QOS settings in the profile on the WLC does not mark packets, it simply allows packets that were marked by the client to keep it's markings up to a set level.
If you want Wireless Voice to work on your PC's.
1. Make sure that SSID is set to Platinum (Make sure Platinum is set to a value of 6).
2. Make sure CUCM is configured to use the desired DSCP values for call control and RTP traffic.
3. Trust DSCP on the switch port connecting to the on the AP.
The risk that you take here is that it allows an application on the PC to mark it's packets up to EF and it could chew up your entire priority queue on your network. This is why most people put the wireless phones on it's own SSID.
I hope this helps.

Hi All,
I have this problem with VOIP phone calls been very poor, and need to fix it ASAP.
I have a stalite link between the Head office and Branch site.
Head office is cisco 3845 and Branch is cisco 3825.
And the Phone system is NEC ( with IP Trunk) via the GRE tunnel.
I have a GRE Tunnel between the sites since the IP address I am using on the LAN are Not supported by the sat Provider.
Can you please have a look on the attched and advice if I am missing any thing.
I have configured a QOS setting and applyied it to the tunnel interface per the following Cisco guide
http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008017405e.shtml
but the QOS polices are not Matching the NEC PBX traffic.
Thanks for your help
Nourdo u know what is the default marking of that traffic i mean the NEC?
what is the matching crateria u follow to match the NEC PBX traffic ? -
I use a GRE multipoint tunnel interface for dial backup catcher. What I want to do is apply QOS to the incoming GRE tunnels in catcher. Is there a way to dynamicaly apply QOS to a multipoint tunnel when it is formed?
I currently want the same QOS setting on each tunnel, but I believe if I apply it to the multipoint tunnel it will apply QOS to the cunulitave traffic rather than the individual streams. Right?
Applying it on the incomming interface of the remote defeats the purpose.A tunnel interface supports many of the same QoS features as a physical interface. The following URl will provide you with more information in configuring QOS in GRe tunnels,
