I remember a time when I taught a class called CIT (Cisco Internetwork Troubleshooting) and there was a wonderful rule that made all the students sweat a little more and all the instructors give that old Dr.Claw laugh (From Inspector Gadget if you have no idea what I’m talking about).  Essentially it allowed the Instructor to do things that were really mean and evil and forced the students NOT to take the easy way out.  What was that rule?  When troubleshooting you may NOT use the command Show Running-Config or any variant of it.

CCIE Candidates,

We get several emails asking if they can see a recorded version of a previous vLecture – well, we’re working on linking these to your IPexpert’s Member Area – but – in the meantime, links to previously completed (recorded vLectures) can be found on our Facebook page (and you don’t even need a Facebook account to get to them!) Visit THIS URL to see the list of vLecture topics and get access to their recordings.

Regards – Wayne

CCIE R&S, Voice, Wireless, Security, and Service Provider Candidates,

I’d like to thank all of the students and (potential CCIEs) who have attended our free online vLectures. It’s pretty amazing, but we’ve surpassed over 1,000 different students (confirmed email addresses) in the very short time we’ve been conducting them! I’m interested in hearing your thoughts on these free online vLectures and would like to get your feedback on what technical topics or items of discussion you would like us to add. We will be completing our 2010 (Q4) and Q1 2011 vLecture schedule soon – so please let me know what we’re missing or what you’d like to hear from our team of instructors! Lastly, we will be adding CCIE Wireless products (and also vLectures) to our website within the next week or two – so we are also taking recommendations on CCIE Wireless topics!

Thanks! – Wayne

We are pleased to announce that we were in attendance at the CCIE Voice Techtorial, given by Ben Ng (Cisco CCIE Voice Program Manager) at the Cisco Live Networkers Conference.  In that 8-hour session, we found out some interesting information regarding the CCIE Voice Written and Lab exam that we would like to pass along to you in no particular order.

There were no changes to the blueprint announced (thankfully!). All software versions will remain at 7.0 and are likely to remain at this release for a couple of years. It is worth pointing out that Cisco are well aware of the fact that there are several “bugs/undocumented features” that can be expected with any “.0” release. However candidates are expected to provide workarounds where applicable.

As most of you know, the Core Knowledge questions were removed some time in May 2010 and were replaced with troubleshooting tasks. The speaker repeatedly brought attention to the types of troubleshooting tasks candidates can expect. We have tried to summarize some of the most important points raised below.

• There is no dedicated troubleshooting section for the time being- troubleshooting is embedded into the configuration tasks of the exam. This is subject to change- in other words they may look at providing a dedicated troubleshooting section at some point in the future.
• Troubleshooting tasks account for approximately 15% of the points on the CCIE Voice Lab exam.
• Candidates will have to troubleshoot existing configuration which has built-in errors. More details of example errors are given below.
• Infrastructure tasks will for the most part be complete and will not be the responsibility of the candidate. However configuration might not be 100% correct!
• Going forward phones will be pre-configured into the UCM database. It was mentioned that SIP endpoints have not been tested thus far but candidates should expect SIP endpoints in the lab in the very near future. Interestingly it is the intention to have phones pre-registered with the correct firmware in advance- that means candidates will not be responsible for changing the firmware of the phone. This will come as a relief to many of you since this process is time-consuming.
• Troubleshooting tasks could potentially include in depth knowledge of the protocols used for establishing call setup. Detailed knowledge of the call flow involved in protocols such as SIP/MGCP/H323/SCCP/Q931/etc will be required in order to explain why certain calls to the “provider” are failing. It was mentioned that the candidate may not even have to fix the problem and instead create a text file with the relevant traces/debugs and a suitable explanation. A process not too dissimilar when you create a TAC case.
• Cisco will continuously modify the content of the lab and this includes changing the number of UCM and UCME sites. You can expect 3 UCM sites, 3 UCME sites or anything in between!
• Gatekeeper/CUBE/SIP Trunk tasks will be added to the lab at some point in the near future (if not already!). The PSTN provider in the lab may not necessarily be a T1/E1 connection but rather a H323 or SIP ITSP.
• Security related tasks (authentication and encryption of signaling and media) are not going to be tested since these tasks are too difficult to maintain and implement. However the CCIE Voice Written test which will be updated later this year will cover those topics.
• The Voice CCIE pass rate is currently between 20% and 25% but expect that figure to drop as the impending lab updates will no doubt increase the difficulty of the test.

Overall we were very pleased with the outcome of the discussion- no major updates for a couple of years will come as a huge relief to all training vendors. The IPexpert BLS and bootcamps have for more than a year now been covering SIP Phones, CUBE, multiple UCME sites and detailed knowledge of the protocols involved in call set up. The biggest takeaway from the session was undoubtedly troubleshooting is going to be the singular most important skill candidates will need to pass the lab – if you are going to pass the CCIE Voice going forward you need to focus on the why and not only the how as has been the case in the past.
