RE: number of CCIE [7:70151]
Folks, The CCIE certification has really depreciated in value. There was a time when I proudly used to adorn my designation with my CCIE number. Not any more. Its value to impress is diminishing every day. Anyways, that was expected.

I feel the reason for the headhunters and HR types to value a lower number is due to pure ignorance. Like that matters. You know how it is. It doesn't matter whether you think they're being stupid or not. If they have the jobs and you want a job, then you have to play by their rules, simple as that. Whether you agree with those rules is beside the point. Think about it, when the rent comes due, you either have the money to pay or you don't. You really think your landlord wants to hear you whine that you're broke because you can't get a job because HR is stupid? That's my point exactly. I don't think they're being ignorant or stupid at all - but even if they were, that doesn't change much. At the end of the day you end up in the same place that I am - you admit to yourself that a lower number is better, it's just that we get to the same place for different reasons. My reason is that the lower number does tend to convey higher quality. Your reason is that while you think this is untrue, a lot of people who have hiring power believe it, so you prefer the lower number for yourself simply to satisfy those people. But so what? We still end up in the same place. Most of them can't find their own ass with both hands and a GPS receiver. So? The reality is that they still have power over you, because they have the power to determine who gets a job and who doesn't. You can whine and moan about it all you want, and they will still have power over you. You don't like it? Too bad. It is what it is. Again, I would ask you to be pragmatic. At the end of the day, you want something (a job) that they have the power to grant, and therefore you need to jump through their hoops, no matter how stupid you might think they are. That's life. This comment though insulting, is aimed at the hiring side of IT. This is not aimed at the rest of their functions. I personally feel corp America should move to Argentina and Ecuador and hang out with the rest of the surviving Nazis. 'Course then we'd have a Fourth Reich to contend with and anybody who tried to make a decent living with anything less than a Bachelor's Degree would be castrated or asked to take a shower. Heh! Well, tell us how you REALLY feel. Look, at the end of the day, there are things that corporate America dictates that they want out of their job candidates. Ranting and raving about it isn't going to change anything. They have the jobs so they set the rules. If you REALLY REALLY don't like the hiring practices of corporate America, then fine, start your own company and then you can dictate whatever terms you want out of the people you hire. I don't see anybody stopping you.. It's utter BS to believe a lower numbered CCIE is any better than a higher numbered CCIE. A lab is a lab is a lab of course. Right Wilbur? As far as I know (famous last words but I am not pussing out), there are no BootCamps for the lab portion. The test portion yes, the lab no. Ahem. Ahem. Are you serious?? Did you just seriously say that? Man, I had to check my news client several times to make sure I heard you right. Uh, I hate to be the one to have to tell you this, but groupstudy itself was essentially started by one of the bigger lab bootcamp vendors around - CCbootcamp. I don't even think that groupstudy would have gotten off the ground without ccbootcamp. It's now sponsored by not only ccbootcamp, but also by HelloComputers, cyscoexperts, and IPexperts who all make a lot of money off their lab bootcamps. Trust me, all these companies enjoy thriving business off their lab bootcamp sales. And second of all, a lab is not a lab is not a lab. The fact is, there have been constant fluctuations in the overall rigor of the lab. Labs are not created equal. I remember back in the old days when people would 'game' the lab by deliberately travelling to what they thought were easier test locations where the proctors and the test gear (back in the old days, each location had different racks) were reputedly easier. For example, I seem to recall people saying that if you didn't know SNA well, then don't even think of attempting the lab in RTP because that's where all the stud-SNA CCIE proctors were. This forced Cisco to standardize racks in each location and to rein in certain rogue proctors. There have been
Cat 6509 Scenario - Comments please [7:66211]
Folks, I have two Cat 6509's with two Supervisor-1A-2GE, MSFC, and PFC cards. I just want to know if the two Gigabit Ethernet ports on each Supervisor work independently of which Supervisor is active. 1. I mean will the two Gigabit Ethernet ports on the Standby Supervisor also work and provide connectivity through the 32MBps backplane? 2. What will happen if the active Supervisor fails? Will the two Gigabit Ethernet ports on it still work? I know the MSFC and PFC will fail with the failed Supervisor, however, I am not sure about the two Gigabit Ethernet ports. Thanks all. Aziz S.

Catalyst 6509 GBIC Issue [7:55321]
Hi Group, Is there a way of finding out if a 8-port or 16-port Gigabit Ethernet module on a Catalyst 6509 Switch has GBIC's installed by consoling into the box. A quick answer can be to just look at the Catalyst 6509 from the front, however, I only have telnet access into the switch. Thanks in advance. Aziz S.

RE: ATM Dead?
Hi Group, I think labelling the ATM technology as dead would be an "overkill". ATM has its advantages as well as disadvantages. Mere opinions don't change facts. Following are some facts about ATM: ATM has evolved as a stable connection oriented transport that currently operates, ATM switch to ATM switch at up to OC-48 line rates. It also lends itself ably to traffic engineering (prior to MPLS it was the only technology that offered traffic engineering features). It delivers many advanced features such as PVC creation from any ingress to any egress in a given ATM backbone, sophisticated ( but complicated ) signaling to simplify path creation and re-routing around failures, and QoS features for bandwidth reservation, constant bit rate, variable bit rate, and unspecified bit rate services, applied to the cell. However, with these advantages, ATM also has certain drawbacks. The first and foremost being that of "overhead". ATM consumes nearly 10% of available bandwidth with a 5 byte cell header for each 48 byte payload cell, plus an additional 5% is needed for the adaption layer for IP over ATM as per RFC 1483. For example, an ATM OC-48 link requires 494Mbit/sec for overhead. Compounding the bandwidth issues is ATM's limited scalability at higher link rates. ATM switches have only recently delivered OC-48 interface rates and it is questionable whether OC-192 is feasible considering the overhead associated with segmentation and reassembly, wasted bandwidth, and other inefficiencies of pushing 53bytes across 10Gbit/sec links. Today the fastest IP router ATM interface is OC-12, which creates a bottleneck with the advent of OC-192 capable transport systems. When ATM is used as the transport for delivering IP in the Internet core we face a different set of issues. ATM requires its own administrative domain distinct from IP at Layer 3. The ATM network elements must be interconnected in such a way to provide redundancy. The entire ATM topology is transparent to the IP Layer 3 topology. Therefore a second topology at Layer 3 must be overlaid atop the ATM fabric. This is achieved by establishing PVC's between layer 3 routers. This creates another set of problems: 1. Two separate modalities are required for element management adding complexity and cost to network management. 2. IP route exchange with an IGP requires direct peering/adjacency with all neighbors, therefore the number of PVC's required grow by a factor of n-to-the-power-2; where n is the number of internal IGP routers. For example, for 300 routers: 44,850 PVC's would be necessary to establish a complete mesh. If 4 more routers are added the PVC count jumps to 46,056 (an increase of 1206 PVC's). This represents a substantial network-provisioning problem. In the event of a router failure in this scenario, the surviving routers will issue IGP routing updates on the order of n-to-the-power-3 (300 routers would issue 27 Million updates). This effect can be reduced by configuring route-reflectors/confederations, however, it still adds to the complexity and becomes a provisioning nightmare. 3. ATM uses its own signaling protocol (PNNI) to establish PVC's. IP uses OSPF, IS-IS, and BGP as its signaling protocols. The two signaling layers operate independently and therefore complicate interworking between the layers. To gain advantage of ATM traffic engineering features IP signaling protocols must run within the ATM PVCs. The question boils down to Howard's C. Berkowitz's often-quoted saying, "What is the problem that you are trying to solve ? Knowing the advantages and disadvantages that ATM offers, educated choices regarding its usage can be made depending upon one's application. Aziz S.
