Re: [OSL | CCIE_Voice] Last Chance to Register for IPexpert’s Online Voice “Alchemy” Class….
Hi Wayne, I was in Ken's class tonight and I have to say I think this is awesome ! Way to go. Tonight, the first night, we talked lab strategy and went over hq switch VLAN config and QoS I know from my lab experience, that this would have helped me out.I can't wait for the other 7 classes. I also like that there is bonus material from Ken. One more cool thing, the sessions are recorded, which I like because I know I won't be able to attend one of the sessions live. Bill Lake was online as well and very active on the Q and A. What did you think Bill and anyone else on there tonight?

CCIE Voice Candidates - I just released a blog, and feel that's it's important for you all to check it out. I don't want this to seem like a sales and marketing pitch (although it somewhat is?, but hopefully you all see the value towards this as it pertains to your CCIE Voice 3.0 prep. I can't give any details, but I would anticipate a new Voice blueprint being announced in the very near future. If you're studying (and hoping to pass 3.0 before 4.0 is introduced) - this post will help with that goal. Last Chance to Register for IPexpert’s Online Voice “Alchemy” Class…. CCIE Voice 3.o Candidates, As most of you are aware – there are leaks that the CCIE Voice lab will be changing soon. Although there hasn’t been an official announcement – I anticipate that this announcement will come soon (possibly within the next week or so). With that being said, if you’re studying for 3.0 – your window of opportunity to pass this blueprint is shrinking! A few weeks ago we announced a new online class entitled “IPexpert’s Online CCIE Voice Alchemy Class“. This course was announced(and offered) due to, what we felt, was a need in the industry.We sought out one of theindustry’s most respected Voice Instructors – Kevin Wallace – and put the course together. As you all know – IPexpert leads the industry in CCIE Voice Lab training – as we have helped certify more CCIE Voice Engineers than any company – worldwide. This course, is highly recommended by me and our team. For such a nominal cost – it’s training that will drastically improve your chances at passing this lab – in that limited window in which the 3.0 lab will be offered. Here are a few facts: Q. When does this course start? A. Thursday, June 7, 2012, 8:00 – 10:30 PM EDT Q. Who should attend this course? A. This course assumes the student has already been through at least one practice lab on their own and that they are at least familiar with the technologies on the CCIE Voice Lab blueprint. Q. What is the basis for the course content? A. This live on-line boot camp walks the student through a new mock lab (that Kevin Wallace created) over a series of eight sessions. Q. What distinguishes this boot camp from a tradition boot camp? A. The biggest difference (huge!) is its focus on lab strategy. There are 12 strategies outlined in what Kevin Wallace calls his “CCIE Voice Alchemy” process, which helps the student “turn their lab day into gold.” This boot camp demonstrates these 12 strategies while working through the new mock lab (in a non-linear fashion). Q. What is the goal of this bootcamp? A. The goal is for the student to complete this boot camp with a much deeper understanding of the technologies on the lab, and (maybe even more importantly) have a set of strategies that they can use on lab day to make the most effective use of their time. Q. Who is this Kevin Wallace guy? A. Kevin Wallace is a CCIE RS and Voice. With Cisco experience dating back to 1989 (on a Cisco AGS+ router running Cisco IOS 7.x), Kevin has been a network design specialist for the Walt Disney World Resort, a Senior Technical Instructor for SkillSoft, and a network manager for Eastern Kentucky University. Kevin holds a bachelor’s of science degree in electrical engineering (focusing on digital communications) from the University of Kentucky, and has also authored or co-authored multiple books for Cisco Press, including: Voice over IP First-Step,Cvoice Foundation Learning Guide, TSHOOT Cert Kit, TSHOOT Official Certification Guide, and ROUTE Cert Kit. Kevin’s website is1ExamAMonth.com. I would also encourage you to review the following 3 videos (below) in which Kevin discusses some very interesting and valuable topics. * 12-Step Strategy Video * Interview w/ a Proctor * Troubleshooting (CCIE Voice) Video Lastly (and what you all want to hear!) – For the few remaining seats, we are offering students an incredible promotion.

Re: [OSL | CCIE_Voice] PSTN issues
What is the phone type? You might try doing a hard reset of the phone it's self. Press and hold # while you power cycle, when lights start flashing input 123456789*0# let it sit. Note make sure you have your dhcp and TFTP server still reachable at this point. Just wait and let the phone do its thing. I have seen in the past where some of my phones act a little screwy like this every now and again, sometimes this reset straightens out.

I haven't changed my hardware VPN connectivity at all. Has anyone else seen issues lately?

Re: [OSL | CCIE_Voice] NTP Master Dilemma
You don¹t want to use both an ³ntp master² (my clock is the master) and an ntp server (this is the ntp server I want to sync with) command together. Cisco IOS will respond to ntp requests if a) it is the ntp master (ntp master command) or b) it is synced to an ntp source (ntp server command). So, for example, let¹s say that you want to sync R1 to a backbone ntp server, and have R2 and R3 sync to R1. You would do: R1: ntp server backbone ntp server¹s ip address ! You¹re telling R1 to use ntp to sync to the backbone server ntp source interface name ! Optional - You¹re telling R1 to use a specific interface for sourcing all of its NTP traffic R2 R3: ntp server R1¹s ip address use the address of the interface you set in the ³ntp source² command on R1 if you set one In the above scenario, R1 will respond to ntp requests, R2 will respond to ntp requests, and R3 will respond to ntp requests. No need for an ³ntp master² command. Scenario 2: You want R1 to provide ntp to R2 and R3, but are not using another ntp server: R1: ntp master stratum number ! You¹re telling R1 to respond to NTP requests and say he¹s a certain stratum clock. ntp source interface name ! Optional - You¹re telling R1 to use a specific interface for sourcing all of its NTP traffic R2 R3: ntp server R1¹s ip address use the address of the interface you set in the ³ntp source² command on R1 if you set one HTH, DQ On 6/8/12 1:19 PM, Mann Chaddha mann.chad...@gmail.com wrote: Hi Experts I am due for my next Lab attempt in 5 days time.

Re: [OSL | CCIE_Voice] Proctor Labs issue?
As a follow-up: this is an ongoing issue based on a ProctorLabs reconfiguration from the network issue they experienced earlier. For users on software VPN, setting your MTU to 1300 seems to fix the issue. For hardware VPN users, setting the MTU to 1300 doesn't seem to have fixed anything. I'm waiting on guidance from PL and will advise when I have a workaround / fix.

Re: [OSL | CCIE_Voice] NTP Master Dilemma
I've never taken the lab. I can give you my opinion. I suspect Cisco may vary the Stratum of their NTP server on purpose by day/week, etc. Throwing students who think they know the answer off. So the answer would depend on what Stratum you getting. Generally I don't think you won't need the master command unless they are giving you a bad stratum =10 which CallManager won't like. Verify your hardware is close to current time via show clock. Show ntp association detail --is your master sane or insane, if not why? sc#show ntp assoc detail 172.10.64.254 configured, our_master, sane, valid, stratum 7 ref ID 172.100.64.10 , time D37CCC06.0A26BD47 (03:07:50.039 HKT Sat Jun 9 2012) our mode client, peer mode server, our poll intvl 64, peer poll intvl 64 root delay 0.00 msec, root disp 37.17, reach 377, sync dist 0.04 debug ntp to your buffer in background From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Mann Chaddha Sent: Friday, June 08, 2012 1:19 PM To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] NTP Master Dilemma Hi Experts I am due for my next Lab attempt in 5 days time.

Re: [OSL | CCIE_Voice] NTP Master Dilemma
Based on my testing in the home lab, I suggest to not use 'ntp master' and ntp server at the same time. To sync to an external source, all you need is 'ntp server' command. Also, I could not find a cli command to setup ntp in CUCM, only way to do it is via GUI. Good luck!!!

Re: [OSL | CCIE_Voice] Proctor Labs issue?
This issue should have been resolved now. On one of the Virtual-Template interfaces we needed to change the adjustment of the TCP MSS to reflect the VPN overhead. For some reason it was overlooked and caused issues that you are all describing. It was fixed some 3-4 hours ago. Those of you who are using software VPN - please make sure your PC/Mac MTU is not larger than 1300 bytes. It should have already been set to that when you installed your VPN client, but some download optimization applications increase this. -- Marko Milivojevic - CCIE #18427 (SP RS) Senior CCIE Instructor - IPexpert ___ 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] NTP Master Dilemm
You still only need the ntp server command. Lets say the requirement was to sync the HQ router with the PSTN router and then all other devices sync NTP with the HQ router. On the HQ rtr the only command needed is ntp server 10.10.100.2.

Re: [OSL | CCIE_Voice] NTP Master Dilemm
Sorry got called away Where I was going is they could test you on the ability to sync with external and set your router to a higher stratum number as backup in case primary fails. If the external is not available then your entering ntp server will not work because it can not sync time with the ntp server as it is not available but if you do the below it could work. This requires you to sync with external ntp, then update the routers internal clock, and finally set ntp master with stratum. This config is not reliable so I doubt they are testing it but they could as it is in scope Sample is I set the following Ntp server 10.10.100.2. Running show ntp stat shows synced with it at stratum 5 Then I sync the internal calendar Clock update-calendar Now try ntp master 10 (CUCM won't sync time with lower stratum) Now the problem I have seen is that sometimes it will sync locally even when external ntp is working Bill On Jun 8, 2012, at 7:00 PM, Jason Murray murr...@usa.com wrote: You still only need the ntp server command.
