Sounds like a memory problem. Please check installed DRAM and also IOS version you are using. Your router probably runs out of memory while trying to establish outbound connections.

Agreed, with respect to finding jobs. But a caveat -- once you have a track record, the knowledge is more important than the credential, especially if you've been in the field for a while. I certainly will agree that the learning and thinking modes are different between CCIE and computer science PhD, but they are complementary. I am _NOT_ saying don't get certifications, especially in the earlier parts of your career (after your immediate college opportunities have passed). I'm saying they are one part of a whole. Take the example of the IETF or IRTF. The only time I can think of that someone's degree comes up, or doesn't, is usually when someone is annoyed at Tony Li and refers to him as Dr. Li. Vint Cerf gets called Vint, although his signal honor is that he's about the only person that shows up at the IETF in a three-piece suit and doesn't get assumed to be a marketdroid. One of the big problems with OSI development is that the meetings tended to be attended by professional standards-meeting-goers who had never written or tested a line of code. With a graduate degree, you can branch out far and beyond network engineering. And also with knowledge that comes from the true theoretical background. In this economy, I'll take what I can get. Luckily, some of what I get is in cardiology and pharmacology, and I know medicine well enough to conceive and propose diagnostic and treatment algorithms. I'm probably picking up a contract in the AVVID area, and, while I may not be up on the command set of the most recent product, I feel very comfortable in my understanding of the theory and the more recent technology. To illustrate, take a look at Cisco's top management. You will find nary a one who carries a CCIE. By and large, this is true in development engineering but not the TAC. There are some CCIEs that have moved from support into development, but I can't think of a key developer (including those that moved to Juniper, etc.) that has a CCIE. Nobody in my router research group at Nortel had any certifications, unless you count my inactive CCSI and *blush* my 1972 Registered Business Programmer, attesting to COBOL skill. So, again, it really all depends on what you want. If you're perfectly cool with slinging boxes for the rest of your life, then by all means ditch college and just get the CCIE. But if you think you'll ever have any ambitions for anything else, get that degree. The degree is much more important than when I started -- at a time when there were no CS degree programs. Still, even if you can't go back to school, the theoretical knowledge is out there, sometimes in IETF/NANOG/IRTF/RIPE documents, some in professional society (IEEE, ACM) archives, some in the publications of academics and research centers (e.g., CAIDA). You can get involved with mailing lists and local professional societies, and start writing and speaking to get some reputation. And, once again, I would reiterate that while you might be cool with slinging boxes now, 20 years later who knows how you'll feel? I constantly run into a lot of old-timers who regret not having gotten their education and are simply tired of taking orders from some 20-something manager. My variant is explaining to a 22-year-old programmer (with no degree) that is concerned that I might break something given a UNIX root password, and trying gently to remind him that I was administering UNIX systems when he was still being toilet-trained -- and I know UNIX networking better than he does. No, I don't want a neato-keen web interface since I'm only talking between computers -- I want to spawn subprocesses on the particular system, and know the internal IP addresses and well-known ports for some of the other machines. *sigh* Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=60063t=59481 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Now, some unethical managers may just take your idea and run, so don't give away every idea. If you are a consultant, there is a very fine line between demonstrating your competence and giving free consulting. now this topic might make an interesting thread, if not entirely appropriate to this newsgroup. back in the days when I didn't know anything, it used to tick me off that it was so difficult to find anything written in English about networking or computers or programming. I was convinced that there were simple answers to the questions I was asking. Years later, I still don't know anything, and I am still convinced that there are simple answers to the questions I am asking. Call it progress. But you see the mentality here on this newsgroup, and on many other technical newsgroups. The question comes in the form of I work at a company, and we want to do X so how do I do it? I see the problem as stemming from the fact that someone was hired to be the computer guy and his boss expects that the computer guy he hired automatically knows everything there is to know about computers. Poor employee, afraid of losing his job, afraid of being replaced by someone who kows more, seeks out free help, mainly so the boss doesn't find out said employee's limitations. It never helps when the management you work for seems to believe that all you have to do is flip a couple of disks and the job is done. call it the curse of Microsoft, who made computing easy enough that most dummies could do most things, like install software. setting up a PC is no different than setting up a live streaming video over the internet for that technology stock conference we are going to have in three weeks at the hotel up there on the hill six blocks away - the one with the wiring infrastructure circa 1940. free consulting is something that tends to be part of the game, particularly with the higher end of the scale, so it seems to me. I generally don't have problems with smaller companies. of course their needs are usually simpler, and their management understands that they have hired on the cheap for their staff, and they consider bringing an integrator in once in a while as the more economical course of operations.

It's an address that you make up, (making sure it fits any addressing schemes you might have and isn't a duplicate of anything else, of course). It is the address that the router uses for the real destination MAC address when an end station sends a TEST frame to a host or other destination. In other words, it is the address that the router is mapping the real destination MAC address to. See here: http://www.cisco.com/warp/public/cc/pd/ibsw/ibdlsw/prodlit/dls12_rg.htm This entire feature is a conglomeration of awful technologies that would have maybe worked despite their complexity, if we hadn't upgraded from hubs to swithces. The problem with switches is that they remember where MAC addresses are and get confused by redundant routers in a DLSw+ environment. To avoid problems, the redundant routers map the destination address to unique addresses that you configure. Unless you really need this feature (or have to learn it for CCIE for some bizarre reason), I would definitely stay clear of it! :-) Priscilla Thanks so much for your help in advance, Best Regards, H.

It uses 802.3 with 802.2 and SNAP. A few other protocols automatically don't use Ethernet II either, such as CDP, BPDU, NetBEUI, and IS-IS. Of course, if you're using VLANs, you can change the Ethernet encapsulation to 802.1q or ISL, but the real Ethernet frame is still Ethernet II if you're using IP. If your concern is IP, then 99.99% of IP implementations use Ethernet II. Cisco always defaults to that. If, however, a Cisco router sees a data stream from a host where IP uses 802.3 with 802.2, the router can handle this. In order to make it work, you need to use the obscure arp snap command. So, although you can't configure IP to use anything other than Ethernet II, you can configure ARP to use SNAP for that 0.001% of cases where a host is doing IP on top of 802.3 with 802.2.

Re: CCIE Vs. BS or MS dergree [7:59481]
Deep thoughts from Jack Handy I kind of agree with you that they need decent networking courses at the undergrad level. I don't want to go into my whole reason for going for my bachelor's, but I got my CCNP less than a year ago, and decided I would rather get a bachelor's in comp sci then continue to pursue the CCIE. A degree is so much more flexible. I would advise most people to go for a degree, then you can get the CCIE later( who knows it could be called something else or it could be abolished altogether). The degree will always be with you. Plus, you broaden your scope and you will appreciate all aspects of computers. You might even like programming and then you can be the guy/girl that writes the code for the newest routers.

Re: CCIE Vs. BS or MS dergree [7:59481]
Ok, I've been following this thread for a while now. I'm a student currently working on my BS in Computer Engineering and I'll only be on my soap box for a few minutes here. Colleges used to be on the bleeding edge of technology and now they aren't anymore. I'm a network security engineer by practice and I'm having to study programmming and electronic design. Granted this is good and important, because I must understand how the technology works but while I'm learning the 1970s art of electronic design I'm missing out on the latest in network design. Currently colleges are in the mindset that you must be a grad student to even attempt networking and that is killing me. Look at how many universities offer MS and PhD programs in Network Engineering, but find one popular university that offers the same program to undergrads. I walked into a research lab full of grad students that were using out-dated Cisco and Bay equipment to study for their CCNA. They were amazed to find out I got mine while still in High-School almost 3 years ago (Yes I'm due for recert in May). The universities need to work on building programs in networking and computer security at the level of Computer Science and Computer Engineering. Sure you can argue Networking is a subset of both programs and thus a specialization that must be obtained after your BS. However, if thats the logic then therefore a Landscape Architecture student must first major in General Architecture and then work on their MS in Landscape Design. Which is not the case. Another problem is that there are absolutely ZERO Network Security or Computer Security courses at the undergrad level in my school (Virginia Tech). So we are letting all these programmers out the door without ever teaching them buffer overflows, or other security issues. And we wonder why every system built has security flaws out the wazoo. Now I've tried to take classes above my degree program and have been refused admission in all cases and that is so fustrating. Because for me the only way to stay up on technology is to do research on my own for no school credit, or to take a job in the world and forget about school.

And now with budget cuts its getting worse and they are scratching classes right and left. I understand everything you said, and I agree that college coursework should modernize, but I think you may be missing the point of a college education. The point of a college education is not to prepare you to step into a job immediately. That is not its purpose, and never has been - even for such 'professional' degrees like engineering and CS. The purpose of the college degree is to provide you with a a reservoir of general knowledge upon which you can draw, as well as practice in life-skills such as problem-solving, critical thinking, and time-management. In essence, you learn how to learn. Consider this. The top Wall Street investment banks and management consultancies hire numerous students from a wide range of majors - and give preference to engineers. But why? What exactly does mergersacquisitions have to do with Shakespeare? Or the philosophical theories of Rousseau? Or thermodynamic and quantum-mechanics equations? Answer - nothing. But that's not the point. Goldman Sachs doesn't hire somebody fresh out of college because they think he knows the gory details of how to close a billion-dollar stock offering. They hire him because he has proven in college to be a hard-worker who knows how to think critically. This is these companies put such an emphasis on GPA - not because they actually think the subject matter has anything to do with the job, but because a top GPA indicates a strong work ethic and a supple mind. To wit - look at the top management of any large company and notice how by and large everybody is a college graduate. Look at Congress - everybody's a graduate. Clearly that means that there's something going on, and that the degree isn't totally worthless. In fact, consider the case of the most famous dropout of all - Bill Gates, who himself has chosen to fill the entire ranks of Microsoft's top management with college graduates. Gates could have put whoever he wanted into those positions, so if the degree really wasn't valuable, don't you think Gates would have figured this out by now? If even Gates agrees, I would say that clearly there is something valuable about that

It uses 802.3 with 802.2 and SNAP. A few other protocols automatically don't use Ethernet II either, such as CDP, BPDU, NetBEUI, and IS-IS. Of course, if you're using VLANs, you can change the Ethernet encapsulation to 802.1q or ISL, but the real Ethernet frame is still Ethernet II if you're using IP. If your concern is IP, then 99.99% of IP implementations use Ethernet II. Cisco always defaults to that. If, however, a Cisco router sees a data stream from a host where IP uses 802.3 with 802.2, the router can handle this. In order to make it work, you need to use the obscure arp snap command. So, although you can't configure IP to use anything other than Ethernet II, you can configure ARP to use SNAP for that 0.001% of cases where a host is doing IP on top of 802.3 with 802.2.

The only point I'm hoping to show is that the colleges have become a corporation and that they are only interested in profit and not the personal instruction of students as they once were.

Great Cisco Resourse - Mcast, Qos, MPLS, etc.` [7:60081]
I wanted to share this resource with you: http://www.cisco.com/warp/public/732/Tech/ Perhaps I have been living under a CCO rock all of my life, but this was a great revelation to me. First, it's public. Second, it includes internal Cisco training materials. There have been several inquiries over the last few months for good CCIP info (esp. mcast and QoS). Well, from the above, follow the link to Multicast and then to Learn About Cisco IOS Multicast and finally to IP Multicast Training Materials. You will find about 1,000 pages of training material on all things mcast. It appears to be at least, if not more, detailed than the CP book Developing IP Multicast Networks, Vol I that was discussed recently. I suspect the author was heavily involved with the development of the training material. I haven't looked into the QoS site much, but I suspect it is on the same level of detail. Since I've had a CCO login for some time, I've always used the non-public: http://www.cisco.com/cgi-bin/Support/PSP/index.pl?i=Technologies Frankly, I'm not sure that I don't prefer the public site.

It's an address that you make up, (making sure it fits any addressing schemes you might have and isn't a duplicate of anything else, of course). It is the address that the router uses for the real destination MAC address when an end station sends a TEST frame to a host or other destination.

To avoid problems, the redundant routers map the destination address to unique addresses that you configure.

Yes, these places teach things that have a vocational bent. But there is always a great deal of theory and general knowledge-building as well. Practically all of these schools teach languages like SCHEME, Pascal, LISP, and the like - which are not exactly the most popular languages in the working world today, but are extraordinarily useful for teaching fundamental concepts. True, the schools then move on to things like Java and C, but the underlying tone of the curricula is always to understand theory and rigor - not just to slap together a bunch of code that will work but is computationally inelegant.

Like I said, there is significant room for improvement for college curricula. I agree that some school probably should foster a degree program that concentrates on networks.

True, many times these programs are restricted to honors students or some other type of elite designation.

Let's face it. The guy with a 4.0 probably worked harder and is brighter than the guy with a 2.0, all other things being equal (especially if they went to the same school and studied the same major). No guarantees of course. But the trend is clear. It's a fundamental misunderstanding of the way statistics works to say otherwise. Obviously there are some geniuses who have poor GPA's. And there are some idiots who have good GPA's. But the fact is there are a disproportionate number of geniuses with high GPA's.It's like saying that smoking is dangerous (I hope you don't disagree with this). That's not to say that everybody who smokes will die young, and everybody who doesn't smoke will live a long life. But the trend is clear - smoking, on average, tends to hurt your health. Clearly I hope that if your kids ask you whether they should smoke, you are going to tell them not to, instead of giving them some spiel about how statistics are imperfect. Or, let me put it to you this way. You say that GPA is an imperfect indicator of ability, and I agree. Yet you argue that you can write an app and that kind of thing, and that should be used as the indicator. However, I could easily argue that that is an imperfect indicator also.

why this caused whole network hang? [7:60090]
Hi.. I have one of my 2900 switch connected to my backbone switch(5500). A few day ago, I found that the switch to switch connection has duplex mismatch error. The 2900 sw interface was set to 100 full dpx. But the 5505 sw interface was set to auto neg, but they fail to negotiate properly. Therefore, I tried to set the 5505 sw interface to 100 full dx. But immediately after I set, the whole company network hang. All users lost connection for more than 10 minutes. I really can't understand why?? The 2900 sw has only one connection to the 5505 sw and both interface set to portfast (faststart) disable. I think it is related to spanning-tree but why spanning-tree loop will happen in this case. Can one explain to me.

Strange Problem. [7:60092]
Dear Friends, I have strange problem at hands. I have 2 Serial Sync 64kbps links connecting to 2 different places. The problem is one of the link start dropping packets (after 3 hrs) moment both the links are put one ANY ONE router. I used 1751,2511,2610. I also put a different WIC different cables. I fail to understand what is wrong. The Service provider tells he seen no problems in the link (when complained and asked to run his tests on the links.). Has anyone faced such a problem before??? Any help is appreciated.

Brief Review - Parkhurst's OSPF Book [7:60093]
I picked up William Parkhurst's book Cisco OSPF Command and Configuration Handbook for the sole reason that I own and have used with great success his BGP book of similar title. BGP has been my most successful section in the CCIE lab twice now, with my most recent result being perfect, due entirely, IMHO, to my thorough study of the BGP book. I believe I have a pretty good understanding of the fundamentals of OSPF, but the biggest room in the world being the room for improvement, I thought I might find some merit in the OSPF book as well. So far I have not been disappointed. I have gone through several of the chapters now, and I am finding the format, the methodology, and the examples extremely conducive to my learning process. Some people can read RFC's and actually understand them. I struggle. Some people can read the CCO configuration guides and comprehend. After a couple of years, I still have mixed results. Parkhurst himself says in the introductions to both books that documentation is the one thing in common among all who experience frustration during the learning process - specifically amount, clarity, and completeness. His books are his way of addressing those shortcomings. Now it can't be easy writing this kind of a book. It is the result of a lot of boring setup and example creation, along with innumerable screen shots of actual router output. The work had to have been a grind after a while. Every command is listed, along with each switch to that command. An explanation of the command is given, followed by a stated purpose for the command. Then lab configuration examples are given, booth before the execution of the command, and after, so that you can see the result. If you are following along in your home lab you can compare your result to the book result. the book is divided into chapters, each containing all the commands related to a particular aspect of OSPF. For example, there are chapters on process configuration, area commands, route filtering, timers, interface commands, and summarization, to name a few. some chapters are obviously shorter or longer than others. examples abound. many examples can be worked with only two routers. no example I have seen as yet requires more than four routers, although YMMV depending upon the numbers of interfaces of particular types. I've even found a couple of interesting things as a result of using the book that I am unable to confirm or deny as a result of reading the documentation. I plan on providing a documented example maybe this weekend, when I turn things back on again. it revolves around authentication. the only disappointment I have so far is the coverage of OSPF over frame relay. The basics are covered quite well. It does not appear to go into the many variations that are possible. I will be spending some router time with this section over the weekend as well. Howard attempted to get a discussion going earlier this week about practice lab design assumptions, something that has so far drawn little attention ( as opposed to the CCIE versus college degree thread that just won't die ) I'd kinda like to see a discussion of book writing / training material writing design as well. I personally believe the Parkhurst method, while maybe not the be all and end all of study materials, packs a lot more into it's pages than most others I have read. I wish there were more like the two Parkhurst books.

RE: Built-in CSU capacity [7:60022]
Hi all, There is a rule called 75 percent rule. The router permits the user traffic to use only 75% of the link speed by default. The reamining part is leaved for the Layer2 keepalives, routing updates. You can override that value by entering max-reserved-bandwidth command under the interface. You should define what percent of the link you want to use as the command parameter. For example you can enter max-reserved-bandwidth 95 to make your traffic use 95% of the link speed. Happy new year from Turkey. Best regards.
