Re: [OSL | CCIE_Voice] QOS WAN
A few comments inline below in RED... On Tue, Oct 1, 2013 at 11:00 AM, virajith vir...@rediffmail.com wrote: Hi Justin, Thanks for your reply. After taking out and reapplying the config it appears that the HQ to SC issue for calls work. The calls between SB , HQ , SC also work. However when inbound calls come from pstn to the H323 gateway leading to the PSTN I notice that it gives a fast busy. Upon removing QOS the calls work fine. Justin: look at the response below for question 3 on LAN QoS...if I come up with something in particular I'll let you know. Take a close look at your singling path between the gateway/CUCM and the phone/CUCM in the example as both are crossing the WAN (unless this is your HQ site), while the media gateway/phone should be local (unless somehow you are using an MTP at a different site?). One-way cRTP over WAN will cause issues, but this *should* only apply to calling over WAN and not to a gateway talking to a local phone (ie, not crossing wan - unless you have a home lab where using HQ switch to power SB/SC phones across WAN). Questions: = 1) Would you recommend applying wan qos manually? is it the same procedure ? Also how is it different from the auto qos option? Justin: I always use auto qos when the question asks for MLP. It can be done manually but there are a lot of commands to build the virtual-template and I cannot do these faster than auto qos. For FRTS I sometimes use auto qos and sometimes don't (use SRDN) to be familiar with both. If the question asks for class based then I just use the SRND reference config and do it manually. 2) What would be a safe approach to take ? Justin: To avoid issues I save the running config just before and just after auto qos, then use show archive config diff flash:before flash:after to see what auto qos actually did. (I do this on the switch too.) After auto qos I edit as needed, and if it doesn't work after a few minutes of troubleshooting I reload the router and revert to the before config. After it comes back up you can either retry auto qos (faster if it works, but if it doesn't you'll lose more time to reload again) or apply it manually (because you already have the cli from the first time and your tweaks). 3) My LAN QOS has not been setup on the switch ? Do you think that this could cause an issue on the WAN? Justin: I don't think the lack of LAN QoS would affect much on the WAN, although without reviewing a specific scenario I don't want to suggest its not possible under a unique circumstance (I can't think of one at the moment). However, you need to consider the end-to-end QoS from phones/servers/gateways marking traffic and the switch and/or router re-marking/shaping/policing. For example, if your WAN QoS polices signaling at CS3 to 5% there are differences between the trusted and untrusted versions of auto-qos. The untrusted methods will build ACL/NBAR to mark your traffic, but the trusted method relies on a correct marking already. Phones and servers should mark signaling CS3, but this old version of IOS uses AF31. You will need to set your generated singling to CS3 for mgcp (mgcp ip qos dscp cs3 sig), dial-peers (under dial-peer voip: ip qos dscp cs3 sig), and sccp (sccp ip precedence 3). Router generated media usually defaults to EF.

Shut down one and verify that you can still get to the other (correct) site. For Site B - I noticed an interesting line in your R2 output on physical s0/1/0 it looks like it is set to 56K. I recently had this same issue but didn't have time to continue to troubleshoot. Whatever is causing that to show up may be part of your issue with your site B. The way I got myself in that situation was by configuring under the wrong subinterface (and creating one) and then no sub-if without removing the map-class. When I get time to lab I plan to recreate this and then try putting the wrong sub-if back, remove the map class, then delete the sub-if. I don't see anything that jumps out for your site C but will compare that to my results next time I lab (probably tomorrow) On Mon, Sep 23, 2013 at 11:46 AM, virajith vir...@rediffmail.com wrote: Hello Justin, Thanks for your reply.

Re: [OSL | CCIE_Voice] QOS WAN
At first glance those steps look ok. What do you see from show traffic and show frame-r pvc # on all three site routers? For odd audio issues I would look at LAN QoS (make sure you're not policing too low) and ensure you don't have one-way LFI or cRTP (which looks like you moved crtp to policy-map already). For SC phones not registering double check to ensure your frts is keeping that PVC at 2M and its not at the default 56k once frts was enabled on physical interface. Worst case you could back out the configuration, reload, and reapply the config either using auto qos or use your current config as a template and apply manually. You could also post you full cli configs for review. -Justin On Sun, Sep 22, 2013 at 10:30 AM, virajith vir...@rediffmail.com wrote: Hello All, Any update? I am still waiting for a reply.

Re: [OSL | CCIE_Voice] [QOS Question - To get proper understanding]
If you are trying to match traffic from a single server wouldn't you want to match on ip? You might try a class map that does match all and have it match sip and the IP address of the server in question.

[OSL | CCIE_Voice] QoS
Hi guys, I want to know what is the idle solution for LAN and WAN QoS. I have read too many responses which has confused me. 1. For LAN QoS, what will be the access-list? Do we have to give source ip address of CUPS in the access-list.? What abt the other server connected to the same port? 2. For WAN QoS, do we have to change the CIR/BC/BE values to 95%? What abt the second link to SiteC value which gets defaulted to 56K after enabling Qos on the first sub interface? I am confused abt using auto qos voip trust and auto qos voip trust fr-atm. Which one we have to use? Any input will be appreciated.___ 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] QOS big question
Hello Ikizoo4, and friends, Here is what I found through a number of experiments and theories: When you implement QoS priority for voice and CBWFQ for other queues, the policy is implemented only when you have CONGESTION. To test the scenario, you should have congestion, as only when in congestion, IOS invokes queueing mechanism, otherwise if a queue is empty, IOS will dynamically attempt to redistribute that bandwidth to other queues in proportion to their configured bandwidth commands. Since we are testing in an environment where there is typically no other traffic, we are allowed to make even more calls than priority bandwidth allows to. We should, in addition, make sure that traffic classification is done accordingly.

Re: [OSL | CCIE_Voice] QOS big question
A very basic QoS question, I must say. Go to the intended interface, issue bandwidth 384 command and go into frame-relay dlci. run the auto qos voip trust It will prepare you the required MQC. In the same sub-interface the auto qos adds frame-relay ip rtp header-compression, you should remove this to enable crtp. Now, get the output that is created by auto qos for you. I prefer sh run | s map. Copy the contents and tweak as per your requirements. For example, say your requirement for signalling is 16 k then, in the class AutoQoS-VoIP-Control-Trust, remove bandwidth percent command (no form, obviously) and add bandwidth 16 command. For four G729 calls, calculate total header and payload, and come up with the required bandwidth. My fav is 49 for four calls. Hope This Helps.

hi folks, I have two questions in QOS. 1. When classifying a qos traffic for CTI Cube I used access lists. ip access-list extended CTIQBE match tcp any any eq 2748 match tcp any eq 2748 any Question is there any other method to clasify traffic in QOS CTI CUBE ? 2. When bandwidth classification in policy-map section policy-map CBWFQ_BR1 class voice-media priority percentage 25 class voice-signaling bandwidth remaining percentage 5 In above is it enough that 5 percent from remaining traffic in 512 Kbps line. what is the calculation required.

[OSL | CCIE_Voice] QoS Access List
All, There have been some questions about the fact the when you do an access-list on a 3750 and attach it to a class-map for QoS purposes, the show access-list command does not show hits on the ACL. I did some research and that is how the switch works. http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/1 2.2_44_se/configuration/guide/swacl.html The switch does not support these Cisco IOS router ACL-related features: ACL logging for port ACLs and VLAN maps If you read further down it says you can put Log on your entries so you can see hits via syslog messages. But if you try to do it for QoS, you get this error message class-map CLASS_MGCP : access-list with 'log' not supported, pls remove 'log' from access-list otherwise class-map CLASS_MGCP will not work properly I tried to put the ACL directly on the router for giggles but it caused the switch to stop passing traffic. I saw the document advising this could happen but my ACL only covered MGCP so I thought I would be ok. The moral of the story is, you just have to trust your config and use qos related show commands to get a feel for what is going on. ___ 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?

The problem with your example is that the frame-relay ip rtp header-compression is out-dated and the header compression should be in the policy-map in the rtp class.

No grading is not affected, because it is allowed to use manual qos config
and so you can use whatever you want for the names.

Re: [OSL | CCIE_Voice] QOS solution problem
Auto qos is acceptable in some situations but be sure you can configure it manually because things like class based shaping require manual config. As for which auto qos to use, you are best off trying each of them several times so you can see what they do. You may have requirements and by trying them you will know which one fits which need In general you would use auto qos VoIP trust for frf12 if dscp is trusted and without trust if not.

[OSL | CCIE_Voice] QoS Question
Hey, I was hoping to get some input on my QoS calculations for header compression. I have been using the Cisco 360 program, and in their exercise workbooks it takes into account the 4 byte checksum for UDP, but I ran Wireshark in my lab to confirm the values. From what I see, the UDP Checksum is disabled on RTP traffic which really means the value is 2 bytes for compression. Which value should be used? Also, the SRND states 8 bytes for FRF.12 and I have always used this, which is contrary to other values I have seen. However, just for clarification, is the 8 bytes a factor of the Frame Relay header of 2 bytes + the 6 byte fragmentation header?

Yes they are for traffic shaping. Average is the rate you want to shape to.

You may have done some or all of these but here would be my troubleshooting steps First thing i would do is check CDP and make sure its operational on the HQ Switch and SB router, I always run these commands on each device cdp run cdp advertise-v2 cdp timer 5 next do a show vlan-sw on your SB router and make sure the vlans are in the database as well as in the active state. Do a show vlan on the switch and make sure those are active as well double check your phone interfaces and make sure the correct vlan assignments are there. double check your ip address assignments on you interface vlan on SB, and hq router and also make sure the correct helper address is there double check your dhcp subnets again to make sure you have the correct info in the correct boxes. Make sure your subnet address ends with a .0 If you have done your ntp configuration before you started trying to auto register your phones ssh to the pub and do a utils dbreplication repair all If you had done any ntp configurations I would run this command anyway As far as you lan qos question each interface has 2 ingress queues and 4 egress queues Jason - Original Message - From: Krishna Sent: 08/06/12 10:24 AM To: Online Study Subject: Re: [OSL | CCIE_Voice] Qos lan egress queue no phones registering via cucm dhcp hi folks, this query is about lan qos and dhcp config on cucm, yesterday i had an issue where i couldn't able to register the Site A and Site B phones to cucm.

Hi folks, I configured the below LLQ-CBWFQ on the HQ and BR1, and when i made the test calls i.e. two calls made from br1 -hq, the calls went through. But in the configuration the rtp allowed for only one g729 call, so will the class class-default taking this traffic??? Any help in giving clarification is much appreciated. And, also i have a question about mismatch of bandwidth values of sites, by default what values will it take. For example, hq is configured for 2 calls for rtp, br1 configured for 1 call for rtp across the frame-relay, so in this case which one wins???

[OSL | CCIE_Voice] QoS config
Hi folks when asked to configure WAN QoS between two sites, with just the following specifics- - allow 2 calls - RTP compression on the link do you do the whole SRND-recommended, 2-level qos policy, including 95% bw calculation ? or do you just do auto qos (trust, if we can assume packets are marked appropriately) and just make sure that the map-class for the other site is adjusted to allow sufficient bandwidth for calls? I tend to do the SRND-compliant config, as it allows us to do compression and shaping at class level, thereby eliminating the need to configure map-class for the other link (which would otherwise end up with the default bandwidth of 56kbps) I am interested in learning what could be gotchas or which words/terms to particular attention to, in deciding whether to go with the hierarchical policy versus sticking with what's generated by auto qos. thanks in advance, /Baktha ___ 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] QoS 3750
I would 100% recommend running auto qos on an UNUSED port for the base config it adds in global config (e.g. cos-dscp maps) - but MANUALLY add port specific commands if required (e.g srr, pr out, service-policy).

I remember some people asking about the priority-queue out command in earlier posts. As I am fine tuning my QoS skills, I found this here on the Command Reference Guide for Catalyst 3750: Usage Guidelines When you configure the priority-queue out command, the shaped round robin (SRR) weight ratios are affected because there is one fewer queue participating in SRR. This means that weight1 in the srr-queue bandwidth shape or the srr-queue bandwidth shape interface configuration command is ignored (not used in the ratio calculation). The expedite queue is a priority queue, and it is serviced until empty before the other queues are serviced. Follow these guidelines when the expedite queue is enabled or the egress queues are serviced based on their SRR weights: • If the egress expedite queue is enabled, it overrides the SRR shaped and shared weights for queue 1. • If the egress expedite queue is disabled and the SRR shaped and shared weights are configured, the shaped mode overrides the shared mode for queue 1, and SRR services this queue in shaped mode. • If the egress expedite queue is disabled and the SRR shaped weights are not configured, SRR services the queue in shared mode. So, watch out for auto qos, because it adds priority-queue out on the port you applied auto qos...

Re: [OSL | CCIE_Voice] QoS Question
Ok- good answer. The one I'm questioning is this: in English when would traffic being placed into egress Q4T3 be dropped? Q4T2 Traffic will be dropped if it exceeds 67% of X unless it could grab 33% of X from the common pool, in this case Q4T3 traffic will be dropped when it reaches X. If this is the case what is the purpose of the maximum threshold (M in my PDF). Is this totally unused? This is maximum memory that this queue can have before packets are dropped to quote the 3750 config guide. Q4T1 and Q4T2 are not allowed to expand their buffers to M (400%) since their threshold values are set to 20% and 50% respectively. How about Q4T3? The Q4 buffer could expand to M to avoid dropping traffic placed into Q4T3 (if common pool BW is available!). Vik Malhi – CCIE #13890 Managing Partner - IPexpert, Inc.

If I allocated 10% using the buffers command and therefore have 10% of the interface's Reserved Memory Pool available for Queue 2, why would I then cut it down from 10% to 9.2%? 2. Does the 400 for Max Reserved mean that T1 +T2 + T3
Re: [OSL | CCIE_Voice] QOS and Payload Size
For (1) it doesn't make sense to me- I would expect them to state that you should use the default payload size (20ms). So I'm not sure on this For (2) with RSVP the call setup ALWAYS asks for worst case scenario which is 40kbps for g729 and after the call is answered the actual bandwidth is used (default 24kbps). So if you always used default payload size (24kbps for G729) and, say for 10 calls, use ip rsvp band 240 then this will only allow 9 calls since the last call will demand 40kbps yet there is only 24 kpbs left (and 216kpbs reserved). So you should allow one call for 10ms (even though the call never uses 10ms sampling rate) and the remainder at 20ms. So for 10 calls- (9*24) + 40.

I just had my second attmpt yesterday, and I failed. What really demoralising for me is that I thought I was fully prepared. What even more demoralising is that when I looked at the score card, I didnt get 100% in the area I thought I would get a 100%. I dont mean to say I know it all (especially now), but there are areas on my score card that really shocks me. As I read through the exam, I know what the questions were requiring (at least I thought I did). For example, we all know that the topics of DHCP, NTP, VLAN will be in the network infrastructure area. And what could go wrong in those areas? I mean, if you dont setup those area correctly, all your subsequence config will has problem right? But yet, I dont get full marks in those. Similarly the gateway area, QoS area etc. Right now I am pretty lost as to what I can prepare or study on, or at least how to check my config? I know this sounds really bad (or arrogent) but I really have no idea as how to confirm the config I did can get the full mark in those area. I guess I am hoping if someone that share their strategy as to how to confirm their work is good or fulfilled the requirement? hope that makes sense? -- next part -- An HTML attachment was scrubbed...

Of course, if the question made you do class-based shaping, then, you don't need to worry about the other links. Only FRTS will cause the links to drop to default (i.e. 56kbps). Always a good idea to do show traffic command, after configuring one link, to see if the other link has defaulted to 56kbps speed. /Baktha On Tue, Feb 7, 2012 at 10:58 AM, ccie_voice-requ...@onlinestudylist.comwrote: Send CCIE_Voice mailing list submissions to ccie_voice@onlinestudylist.com To subscribe or unsubscribe via the World Wide Web, visit http://onlinestudylist.com/mailman/listinfo/ccie_voice or, via email, send a message with subject or body 'help' to ccie_voice-requ...@onlinestudylist.com You can reach the person managing the list at ccie_voice-ow...@onlinestudylist.com When replying, please edit your Subject line so it is more specific than Re: Contents of CCIE_Voice digest...

Re: [OSL | CCIE_Voice] QOS LFI and BACD files
But that won't go for HQ router, as it is a Hub Router -- multiple PVCs per physical interfaces via subinterfaces. For instance, if you have a T1 frame relay link, and already shaped one PVC to 500kbps, you cannot shape another PVC to 1536. You have to shape another PVC to 1536 - 500 = 1036 kbps, as the full interface rate is 1536, while one PVC is already shaped up to 500, so only 1036 is left for shaping.

I did not know that BACD has a built in scripts. And you can configure BACD without BACD tcl files. I would appreciate more details. I would also do some more research to find out how. Regarding QOS I agree that the best way is to set the speed of the second subinterface to T1 (1536). And verify it with proctor.

You have to shape another PVC to 1536 - 500 = 1036 kbps, as the full interface rate is 1536, while one PVC is already shaped up to 500, so only 1036 is left for shaping.

AJ, Take a look at this document, - http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/bacd/configuration/guide/40bacd.html It has examples and talks about configuration with both tcl and embedded.

The DSG guide says the reason for not using the trust key word is because of the following: Note that we have not done any prior QOS classification/marking on the ESW module therefore we will use class-based marking (no use of the trust keyword when running auto qos). But the phones use the following markings by default. signaling (SCCP or SIP) - CoS 3 / cs3 media (RTP) - CoS 5 / DSCP 46 (EF) Why couldn't we just use the trust keyword on BR1 as well since the phone is already marking the packets correctly?

Re: [OSL | CCIE_Voice] QoS question on Workbook2 Lab 10
Hello John , You thinking is correct however as the Packet will traverse over the wan , it will be always subject to get modified by a lot of SW to change specially the DSCP Value and so the QOS SRND recommend to Not trust the packets coming from the wan and so we dont trust in the Branches routers . The right answer for any QOS Question is what is in the SRND and i believe thats why you will find it in the real lap in the desktop Ash On Mon, Jan 16, 2012 at 8:18 PM, John McGaughey (jomcgaug) jomcg...@cisco.com wrote: Hello, In Workbook 2, Lab 10, question 5.2 it asks you to setup MLP LFI between HQ and BR1.

Hi, Just to make this clear. Trusting in HWIC module isn't similar to catalyst switches. For incoming, tagged packets, the Cisco EtherSwitch module honors the CoS value; the packets are buffered in a high-priority queue for CoS values 4 to 7 and scheduled for expedited forwarding. The low-priority queue is used for packets with CoS values 0 to 3. Untagged frames will use the default CoS value configured per-port.

[OSL | CCIE_Voice] QoS for Frame Relay
hello, everyone. I have several questions about the QoS: 1) As I know, the Frame Relay Fragment Size must be always calculated based on the Interfaces Access Rate? Am I right? And when using the Auto QoS on Frame Relay Subinteface, it will calculate the Framgent Size based on the bandwidth command under the Subinterface, and then we have to manually correct the Fragment Size, so that it will be based on the Access Rate and not on the Bandwidth of an interface, am I right? 2) When configuring the CUCM RSVP CAC, we have to configure the ip rsvp bandwidth command under the Frame Relay DLCI interface, and also configure the RSVP MTPs on the Routers. Each G729 call for RSVP is allocating 40 kbps, and for G711 96 kbps. But now look, I have an issue with the ip rsvp bandwidth command: I have configured the ip rsvp bandwidth 40 under the Frame Relay DLCI (Subinterface), so that I have to have only 1 G729 call, and all other calls should be rejected (Not reserved). But my routers are still reserving more and more bandwidth for subsequent calls. RSVP is not rejecting calls, even if I configure the ip rsvp bandwidth 10 command, the calls are still traversing and are not rejected. I have also added the following command: ip rsvp policy preempt interface Serial0/3/0.1 point-to-point frame-relay interface-dlci 101 ip rsvp bandwidth 40 ip rsvp data-packet classification none ip rsvp resource-provider none But still not succes, even 5 G729 calls are reserved and not rejected. I cannot understand why is it so? The debugs of RSVP does not show anything interesing, they are just saying that the RSVP reservation has been succesfull for each call. Maybe it is an IOS BUG? ___ 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?

[OSL | CCIE_Voice] QoS on the HWIC-ESW
In workbook volume 2, lab 2, section 6.1 it says You must trust markings from all endpoints and servers. How do you trust the markings on FastEthernet ports on the HWIC-ESW? mls qos commands are not available (even though the answer guide shows them in there). auto qos doen't do much. The only thing I see is 'switchport priority extend cos value'. But I think that only remarks the COS value coming from the PC that's attached to the phone. I assume the markings from the voice vlan are trusted by default?

Re: [OSL | CCIE_Voice] QoS Shaping and Sharing
You want to rate-limit to 33% of which interface bandwidth this is the question. Are you talking about the trunk to HQ RTR or IP Phone ports. BTW, srr shaped mode is supported for ingress queues.
