[OSL | CCIE_Voice] WAN QoS Calculations
QoS Guru's, In the real lab I know I have to do some calculations utilizing 95% of the bandwidth...so if there is a link between SA and SB of 384k and SA and SC of 768k is the 95% from these numbers or what the actual interface can do? Also what is a simple straight to the point read on this, I really don't want to review an srnd?

Re: [OSL | CCIE_Voice] WAN QoS Calculations
From those numbers, those are the CIR values of the PVC, so you have to use those values. They physical circuit would be a T1, which is academic as the carrier can discard above the committed rate.

Re: [OSL | CCIE_Voice] WAN QoS Calculations
I believe that a 768kbps link falls within the recommendation to leverage a fragmentation mechanism. So, I believe that the map-classes are accurate. Hugo, I know you said you don't want to review a SRND but I definitely recommend you take the time to a look at the WAN Edge Link-Specific QoS Design in the QoS SRND. It is an informative section and not as much of a yawn fest as you may think. Also, if you are ever asked to do class-based traffic shaping, you will be comfortable where to find some good examples. Remember that the QoS SRND is made available to you on the candidate machine. -Bill -- William Bell blog: http://ucguerrilla.com twitter: @ucguerrilla On Apr 9, 2013, at 6:19 PM, Leslie Meade wrote: Hmmm I cannot remember but I am 95% sure J that the fragmentation is not for links over 768… Hence the map-class for the link to Site C is incorrect… remove the frame-relay fragment 960 From: Barrera, Hugo [mailto:hugo.barr...@nexusis.com] Sent: Tuesday, April 09, 2013 3:17 PM To: Abel ...; Leslie Meade Cc: ccie_voice@onlinestudylist.com Subject: RE: [OSL | CCIE_Voice] WAN QoS Calculations So my first set of commands below this is NOT using 95% of the BW and the second set of commands, in blue, are using 95% correct?

Re: [OSL | CCIE_Voice] WAN QoS Calculations
First I used the SRND for LAN QoS and I believe that to be the best way, but I'm sure there are many other flavors. I found using the SRND for LAN QoS to be quick and easy, page 107. It's very efficient way to do it and eliminates mistakes. For WAN QoS I used auto qos voip trust or auto qos voip depending on the question wording. In addition I did QoS first and I know some people disagree with that, but it worked for me speed wise using the device based approach. I did not use the SRND for WAN QoS, but agree is a good reference to have since it's on the desktop of the lab. I used the 95% rule as well as removing the rmon commands. I passed. I agree with most of the comments especially read the question very carefully.

Re: [OSL | CCIE_Voice] WAN QoS questions
1.) it depends, for example if this is a router with switch module in it i.e. BR1, i would not use trust since the marking will be done with acls by auto qos voip 2.) it depends, if you're told to use class based compression then you have to use compression header ip rtp in the policy-map otherwise you can leave as in the interface-dlci 3.) its once again you've to clarify with proctor.. for a full T1 i have never 95% bandwidth so far ... the bandwidth for =768 i have seen using 95% of the bandwidth speed.

Hello experts, I have some questions on WAN QoS. 1. If not explicitly not told to TRUST, is it better to use trust or not? 2. If using FRF.12 and told do use compression, does it matter if it is on the WAN DLCI or the policy map? Always in the policy map? 2A If told to use class-based compression then do it on the policy map. 3. SA-SB is 768KB, SA-SC is 1536KB. When applying the 95% of CIR rule do we need to also apply to SC when 1536KB? 3A - What bandwidth threshold would we not use the 95% rule, above 768KB?

Re: [OSL | CCIE_Voice] WAN QoS calculations
Not sure of a good single reference for all this, but the calculation is... (payload + IP/UDP/RTP overheaded + L2 overhead) x 8 x packets-per-second = bits per second payloads at 10/20/30 ms g729 = 10/20/30 bytes g711 = 80/160/240 bytes (see page 139 of the voice SRND for other codecs) IP/UDP/RTP overheaded 40 bytes without header compression 2-4 with header compression L2 overhead - see page 33 of the enterprise qos SRND packets per second 100 @ 10ms, 50 @ 20ms, 33.3 @ 30ms On Sun, Sep 16, 2012 at 5:39 PM, Randall Crumm rrcr...@yahoo.com wrote: Hi, I can't remember where I looked before, but where can I find calculations or info for WAN QoS for 10ms, 20ms and 30 ms Cheers, Randall ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?

Re: [OSL | CCIE_Voice] wan Qos :police or bandwidth
Bandwidth = minimum bandwidth guarantee. Police = maximum bandwidth allowed. Generally, start with bandwidth then add policing after if you need to limit the bandwidth utilisation.

[OSL | CCIE_Voice] WAN qos question
I ran into a problem the other day that has me confused. I ran auto qos on the hq side, changed values as needed and pasted the modified policy in the hq router. I then took the same policy and pasted it into the SB router config and bound it to the dlci. All seemed to be ok until I tried to get phones registered. I could get a dhcp address but never register. I knew something with the WAN qos was screwed up. I've done it to myself in practice and in the real lab. It turns out that I didn't have frts on the physical interface. Once I put it on, everything started working. My questions are: 1.) I thought IOS would refuse attaching a class to a dlci without frts on the physical interface. 2.) Without frts configured on the physical interface, wouldn't the class assignment on the dlci (384k) effectively be ignored? I know what the config problem was, but I understand what it was actually causing to happen at the Pvc level. ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?

Re: [OSL | CCIE_Voice] WAN qos question
1.) I thought IOS would refuse attaching a class to a dlci without frts on the physical interface. In my experience, it is possible to enable FRTS on a PVC, but you may receive a warning message. If I remember correctly, the message simply states that FRTS commands are required on the physical interface. I wouldn't be surprised if the behavior differs between versions of IOS and MQC vs. legacy FTS, though.

Re: [OSL | CCIE_Voice] WAN QOS Strategy Question.
Hey everyone, I can confirm after A LOT of testing, if you are given a QOS requirement for only one of the two Frame PVCs, and you use Auto QOS, you will have a problem. Auto QOS will automatically config Frame-relay Traffic shaping on the physical WAN interface and then configure the PVC you are QOS'ing to the bandwidth that is noted under the sub interface. The other sub interface gets left with the default frame-relay traffic shaping behavior which is to drop CIR to 56k on the PVC. Do a Show Frame PVC dlci# on both PVC's after running auto qos. I think this could be an intended Rat hole on the exam. If you only have to configure Hq-SB QOS and you don't know much more the to run autoqos and tweak a couple parameters, your SC communications will start to fail with a PVC CIR of 56k.

Re: [OSL | CCIE_Voice] WAN QOS Strategy Question.
This is correct. It's not AutoQoS that causes the problem- its because you MUST have FRTS enabled in order for the map-class to be attached to the DLCI. And this must happen since the service policy is inside the map-class. I recommend you run AutoQoS on all routers when doing WAN QoS or at the very least attach a map-class to all DLCI's. Also be careful if you are using cRTP. You should ensure that if you are using cRTP that both ends of the pipe are configured with cRTP otherwise you will experience one way audio.

Re: [OSL | CCIE_Voice] WAN QOS Strategy Question.
Thanks for clarifying this Vik. I wasn't aware of the crtp one way audio trap. But I'll keep it in mind. One question : I thought we could avoid having the frame relay traffic shaping on the physical interface if we did generic traffic shaping via class-map within the frame-relay map-class. Is this not the case? I vaguely remember what you are talking about where I wasn't able to apply a class to a DLCI and it prompted a message asking for traffic shaping to be enabled. Just wondering if there is work around or is it a hard and fast rule that Frame traffic shaping MUST be on the physical interface.

This is really old information ... There are no catos switches on the exam ...

Re: [OSL | CCIE_Voice] WAN QoS MLP LFI
sure no problem i configured MLP LFI manually and tested connectivity from BR2 and BR1 to HQ, BR2 no problems, because there's no virtual-template however from BR2 to HQ the connectivity was fine unless you reload BR2 router, once the router came back up, I lost connectivity to HQ and of course all the servers after that I tried reloading the HQ router, no difference same issue so i applied the following workaround I went to the sub-interface on BR2 router removed the frame-relay interface-dlci 201 ppp virtual-template 1 command re-added the command re-added the class-map to the fram-relay interface connectivity came back up however if you reload the BR2 router again, i was having the same problem so at the end what it did was fix the connectivity problem, once I had connectivity back, what i did is Reload HQ router once HQ came back up, I could reload Br2 router multiple times and the connectivity issue was resloved hope this helps 2011/7/11 Ronmac ron...@solcon.nl Hi, Maybe a hint on what was wrong?

I know about the bug that talks about when doing MLP LFI it can bring down the link. Generaly on my home lab when this happens i just do a wr mem and reboot, and the link comes back after a reboot. However I am working on Proctorlabs and this seams not to wok. And when I reload the router with the default config and do it again the link goes down and then back up for about 3 mins and then drops... Is there something i am missing ? I did see an error when I was putting changing the qos policy-map in the int, the router rebooted and it happend again 3 more times...

Hi George, Thanks for the suggestion,but as Pablo mentioned it doesn't support the mls qos command. Hi Pablo, Thanks for you suggestion too.I did an sniffing as you advice, what i seen was the udp and rtp ports.

Re: [OSL | CCIE_Voice] WAN Qos with LLQ - Correction**
From my understanding, default serial interface should be 1.5mbps (I'm using real serial not the e1 or t1 which I think bandwidth value might be diff) If you never change anything, it will means u reserve 77kbps ( 5% x 75% of 1.5mbps) But the question asking u to reserve 5%. Therefore, bandwidth command is required. Next is we need to know is 5% of 256k or 5% of the policy-map. By default qos reserve up to 75% of the bandwidth. Use show policy-map interface to verify.

[OSL | CCIE_Voice] WAN QoS from a couple of Labs
I am currently going through some of the WalkThroughs for Vol 2 WB's focusing WAN QoS. In Lab 4; Task 5.1 Lab 5; Task 5.2 in both walkthrus on BR1-RTR when configuring Class Based FRF.12 there is another command that appears automagically in the map-class. map-class frame-relay BR1 frame-relay fragment 480 frame-relay fair-queue ---THIS ONE: which configures WFQ for Frame Relay. service-policy BR1 Vik tries to issuing the no for that command, but to no avail, it just comes back. For the HQ-RTR in the walk thru, that line doesn't show up. However, in my setup for both my HQ and BR1 Routers the fair-queue line appears in my map-classes and I can't get rid of it. What I've read so far is that that line is added with FRF.12, if LLQ is not defined. ref: *http://tinyurl.com/2fbhzl2 *But I have already defined the class-maps and policy-maps etc. Question: How do is that fair-queue line taken out of the map-class? Or does it even matter? In Lab 6; Task 7.1 it asks for 5% of unused Bandwidth for Signaling traffic. In the explanation, Amy shows the calc for 95% of the 1024 link between HQ and BR2, which is 972.8 kbps. Then the 5% for signaling was calc'ed from the 972.8 kbps. Question: Since the priority bandwidth for the 8-g729 calls was calculated to be 224 kbps, wouldn't the 5% of the unused bandwidth be (972.8 k - 224 k) X 5% which comes out to be 37.4 k instead of the 48.6 k per the walk-through? Clarify what is meant by unused. Vik Amy, did not mean to call you out on these, but I felt I couldn't just put the instructor in my explanations. Thanks in advance.

Re: [OSL | CCIE_Voice] WAN QOS question
First of all understand what class-based shaping is- this is shaping within a hierarchical policy-map as opposed to frame-relay traffic shaping and the associated map-class. With MLP LFI you must use frame-relay traffic shaping. With FRF.12 LFI you have a choice of FRTS or class-based shaping. On a single physical interface you are not able to mix and match shaping techniques used. If the two PVC¹s from the HQ site to the two branch sites use separate physical interfaces then you can mix n match. -- Vik Malhi CCIE #13890, CCSI #31584 Senior Technical Instructor - IPexpert, Inc.

[OSL | CCIE_Voice] WAN QoS: AutoQos or No AutoQos ?
Which method is preferred for the Lab AutoQos or Manual QoS Configuration ? What do you feel are the advantages and/or disadvantages of each method ? Thx, Mike Brooks CCIE#16027 (RS)
Re: [OSL | CCIE_Voice] WAN QoS: AutoQos or No AutoQos ?
Mike, My preferred method was manual configuration, however In the CCIE Voice Ask the Experts forum, Ben Ng responded to a similar question with the following answer: Yes, you can use auto-qos to get started, but don't just happy accept everything auto-qos generates, ready the questions carefully to see if you need to customize anything. I think that it would be unlikely that you would be given a question that could be satisfied with simply deploying auto-qos. I'd suggest that you know the configs, know exactly where to find the docs, and be able to customize each parameter given a specific set of criteria. When I was preparing for the voice lab I spend a whole day just working on LAN WAN QOS in the lab. After mastering the content I then memorized the syntax for each command so that I would not have to reference any documentation in the lab.

Re: [OSL | CCIE_Voice] WAN QoS: AutoQos or No AutoQos ?
The problem I've found with AutoQoS is that you often have to go back and change something at some point. You could waste valuable time looking through a Cisco-generated QoS configuration trying to figure out what needs tweaking. Using MQC is my preferred method. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Brooks Sent: Friday, November 28, 2008 9:30 AM To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] WAN QoS: AutoQos or No AutoQos ?

[OSL | CCIE_Voice] WAN QOS Question
I am trying to mark all of my rtp and control traffic at the WAN edge router and not trust the LAN. The issue I am having is that when I try to apply the service-policy to the ingress Ethernet Interface I get the following error. I have tried applying this to the sub-interface as well as the physical interface with the same result.I am assuming I am using the wrong technique to make this happen. Pertinent parts of the configuration are listed below. Any help would be GREATLY appreciated. thx.

It does not work for the input queue. Your statements class class-default and fair-queue in the policy-map voice configured the CBWFQ. For marking purposes only, you mustn't put those 2 statements in your policy-map. You must remove them for the marking policy to work properly. You use those 2 statements when you try to configure LLQ.
