One of my concerns, however, was that some people get the incorrect impression that a CCIE shows qualification for every conceivable networking job. Your analogy to medicine is not bad; it basically says you are ready for the specialty training. More on that later. >Cisco's goal, after all, is not to make great network engineers, >but to make engineers who are proficient with all of Cisco's features and >functions. I do have a problem with the emphasis on "all." There are any number of features that shouldn't be touched unless one has a thorough understanding of the proper environment to use them. I rather regret that X.25 has come off the lab, because it's still an amazing protocol for certain very specialized applications. A lot of the IBM stuff makes very little sense unless you have had substantial experience with mainframes/front ends, and then some of the Cisco features become quite clever. It's probably not unreasonable to know how to configure a basic route reflector, but even though I might JUST be able to set it up with 6 routers, hierarchical route reflectors (and there are a couple of commands, but more design issues) are really too specialized. I'm the first person to admit I know very little about Microsoft networking, especially when one gets into domains and the like. But I can be very busy with real networks and not need that knowledge. In other words, I'd rather see the CCIE a little more specialized (i.e., even more variants), and perhaps a little more in-depth in those areas. There's still a certain mystique that it qualifies someone to work in every area of networking at a senior level, and that's just not the case. >That is why some of the lab scenarios are a bit contrived, and >also why you should be fired for trying to use some of those features on a >real network. Cisco's aim is to make sure CCIEs know how to configure a >Cisco router to solve any problem, even those that shouldn't be solved with >a router! Again, my concern is with "any." I understand why _Cisco_ is well served by some version of that. How does a hiring manager, however, find the people that know when there are better tools than a router for some problems? > >You guys have obviously great expertise in a relatively specialized field. >Should everyone have to understand all these issues before they can rightly >call themselves a network engineer? How many SP jobs are there at that >level, especially in today's market? Good question, really, and hard to answer in the current economy. Last year, I was on an Internet Society panel on the future and scalability of Internet routing. One of my co-panelists was Sue Hares, who is vice-chair of the IDR (BGP) working group and founder/CTO of NextHop. One of her slides read something like "CLI jocks don't scale." In other words, in the minds of everyone on the panel, if the growth rate continues, we MUST develop better automated tools because there simply won't be enough qualified global routing engineers. Once the current economy shakes out, I think you'll find more demand than supply of such specialists, just as you will for VoIP/AVVID, etc. >I would love to be able to specialize >like you have, but the realities of my job require me to be conversant in >everything Cisco sells.

It's important to know where to cut. >It is even more important to know when not to cut. As I say, a good example. It's amazing how many levels of "certification" exist in medicine -- the minimal National Board licensing that lets an intern write prescriptions, the basic residencies such as Family Practice or Internal Medicine or General Surgery, the secondary specialties (examples in Internal Medicine) of cardiology, hematology/oncology, nephrology, infectious disease, gastroenterology... and then tertiary and even quaternary subspecialties like invasive cardiology, split into interventional and noninterventional techniques, angioplasty/atherectomy, electrophysiology, etc. One of the interesting points is that there is more than one way to get into a subspecialty. Hand surgeons, for example, most often come from orthopedics, but a significant number were trained as plastic surgeons. Pain management people are usually anesthesiologists, but can be neurologists or psychiatrists or physiatrists, etc. The same applies to networking. Getting to the most specialized job will require a combination of practical skills, pure theoretical knowledge, and experience.
