icmp [7:66899]
Once i heard, that a ping from a Cisco Box is not the same like a ping from a Windows PC. One is icmp the other is udp. Can anyone confirm? and, where is udp , where is icmp. One solution to make it all clear is to take a sniffer - or i could search my CIT Course stuff this weekend ;-) Martin You may be refering to the traceroute (tracert in M$) utility. Unix traceroute uses ICMP and UDP to discover tha path from source to destination. The intermediate routers respond with ICMP messages. Finally, UDP tries to contact the destination host on a port that is not normally active. The intent is to elicit an ICMP UDP port unreacable messages that tells you that the host is alive and has been found. Windows tracert uses ICMP echo request and ICMP echo reply (PING packet) to locate the destination host.

Fw: Salary Expectations/CCNP's!!!!!!!!! [7:25805]
I have never personally seen anyone in this discussion group ask how to turn a router on. Perhaps you have and, in that case I might agree with you. However, what is easy for you may not be so easy for someone else. I think this thread was started by someone asking a simple question about salaries. The subject was stated plainly in the subject line, so anyone who sorts by subject just simply doesn't have to read it. If you feel as though the subject doesn't belong on the group then why not just ignore the thread vice sending a scathing, derogatory reply that has the sole purpose of making you feel good? As far as the group being a free consulting service, every group member is a volunteer. No one needs a suit of armor to join a discussion. They just need to join it intelligently. That's why it's recommended in the faq to lurk for awhile when you're a newbie before jumping in. If someone posts a questions saying... hey... I searched on Cisco and here and there and I just don't get this... help me understand... no one anywhere would bash them for trying and not understanding. Now if someone posts a question such as how do I recover a password on a 2500, it's obvious they made no effort as this can be found on Cisco's site in less time than it took to ask the question. But perhaps this is the type of intelligent discussion you are referring to and would like to see more of in this group. Well I would argue that by promoting that you are devaluing this group, it's users, and the truely intelligent discussions that go on here. That's just what we all need is to sort through 30 messages a day of how do I turn on my router, what is this ethernet thingy on my rooter, what does ram stand for? Too many people treat this group as the free consulting group and the first place to look for answers and I do not think that should be encouraged. One's own research should be the first place and the knowledgeable people of this group (which I do NOT claim to be one) should asked when that fails.

You have my vote on that. I think there would be many more thoughtful discussions if most average folks didn't feel like they need to put on a suit of armor just to join the discussion. But alas...it seems to be that way in every discussion group. Carrol,. I agree with you that some would learn slower or not at all, but I think you are incorrect on your devaluation of respect. It's easy to say that medicine tastes bad but is necessary. But I propose to the group that the damage is more than the help. There are many lurkers that would surely participate more and in turn learn more through being active rather than just lurking if indeed they could trust that they would not be humiliated if one of their questions was not up to par. So, although a demeaning message may be given to one of the few deserving participants, it will cause many participants not to grow as fast as they would if they were actively conversing. I really don't think you're argument holds water because of that. Besides the same finite resource you refer to are wasted with the rant as with the question. If the resources are the reason for the rant, then the rant is self defeating.

Thank god for you guys who know better, huh? Even the folks at cisco call this nonsense drinking the kool-aid for gods sake. At least they don't believe their own marketing BS. Normally I wouldn't even reply to such a post, but Ive got some residual anger to vent. Do yourselves a favor and wake up to the fact that there are lots of companies out there who make gear thats just as good if not better in many cases than cisco's. What are you going to do when all your old T1 circuits are replaced by optical networks? Have you honestly looked at the market share cisco has in optical networking? Do you understand the products offered by the different vendors? I've got news for you folks, the skills you are all trying so hard to master are already yesterdays news! There is a whole new wave of networking technologies being deployed right under your noses that will totally change the way companies run their networking departments. Most enterprises in the future will outsource their MANs and WANs to managed service providers (running Nortel gear in many cases...horror of horrors) who will hand off an ethernet link at the customer premises. This will go into an L2/L3 switch, not a router as such (running EIGRP of course, so no other vendor's gear can be used). This will provider higher speed links at lower costs while flattening the MAN/WAN and eliminating a whole layer of storing and forwarding (read: L3 software based router). The L2/L3 LAN switching market has become so commoditized that the profit margins are slim to non-existent. The Catalyst switches are based on dated technology, and cannot deliver wire speed throughput while doing anything more than straight L2 (hence the 3-layer heirarchical model a marketing exercise, NOT an engineering one, the whole point of switching was to flatten networks). Cisco will have to buy an established vendor (probably Extreme) in order to compete, since they've written down all the RD they were doing along with their fledgling (CLEC) carrier business. That is why companies like Nortel are not even trying to compete in the conventional router market. Their RD resources have all gone into next generation equipment that surpasses anything that cisco can do. Nortel's enterprise clients are buying Multiservice WAN switches, Sonet, and DWDM; NOT ROUTERS! Hint hint nudge nudge wink wink!

Time limit for CCIE lab [7:15156]
Will anyone answer these questions for me? 1) What is the time limit for taking (scheduling) the CCIE lab after completion of the written? I'm asking because I have seen emails in this group that say one year, and yet I think I've seen a web page somewhere (Cisco??) that says 18 months for the first attempt? 2) Is this the time within which the lab must be taken or is it the time limit within which the lab must be scheduled? To illustrate, if the time limit is one year between written and lab, can I wait eleven months and 29 days to schedule the lab and still be legal?

LMI clarification [7:14608]
LMI has local significance. My provider uses Cisco LMI type by default, however we have reconfigured some of the remote sites to Annex D LMI type. I believe the destination you refer to must mean the provider's local switch. What is important is that your router and the provider's frame relay switch that it directly connects to have the same LMI type configured. Under certain configurations and with certain versions of the IOS, LMI can use an inverse arp process to find the DLCI.

What's wrong with ccie today [7:13160]
Doggone those CCIEs. Shame on them for not knowing UNIX startup scripts. I guess I'll be a step ahead of them if I ever get my CCIE. :) What's wrong with CCIEs today? I know that I am making a general assumptions; however,this is the second time that it has happend to the company that I work for. We have several tacacs servers that use to authenticate users. These tacacs servers are running on a combination of Linux and Solaris platforms. While I was away at the Networker Conference, one of our tacacs servers (solaris) die due to hardware failure and the amazingly the tacacs process on the Linux die. Because of this, everyone has to login to the routers and switches via local account. We hire these CCIEs to maintain the network while I am away for a few weeks. None of these CCIEs have any background with tacacs servers running on Unix platforms. As to our problems, the simple to do is just to restart the tacacs process byfirst: killall tac_plus and second /usr/sbin/tac_plus -C /etc/tacacs/tac_plus.cfg but these CCIEs guys have absolutely no clues. Furthermore, they don't even know how to use editing in Unix (i.e vi or emacs) and ended up screwing up my tacacs configuration files. We have a few employees that need tacacs account but these CCIEs guys have no clues how to addnew users to a configuration file which if anyone has done tacacs on the unix platform know that you just modify the configuration file tac_plus.conf and restart tacacs process. These CCIE guys say that they come from a windows environment so they don't have too much with Unix platforms. I also notice that a lot of CCIEs these days lack the Unix skills that are required for the Service Providers environment. Most don't even know how to tunnel X-application through Secure Shell (SSH). I still remember those days when Cisco Engineers are very well verse in both unix and routers skills. I long for those days again. Comments anyone?

RE: I need an advise [7:11349]
I assume you are on a legitimate quest for information and not just trying to start another flame session on this list, so I'll open myself up and give you my honest opinion. Similar situation for me in 1988. I got the advanced degree and I'm sorry I did. Should have gotten a CCIE (assumming I could've done it). I've been working on certs mid 90s. My reasoning: 1) Age is important when you're looking for a job. People will disagree, but...it does matter. Certification attempts to train you to solve specialized problems now. Degree attempts to educate you to build a judgemental database that can be applied to more general problems in the long run. Few degree programs provide specialized skills that are needed in the workforce now (engineering degree may be an exception to that, in my humble opinion). 2) Many people don't see the difference between training and education. There really is a difference. 3) Most importantly, there is more to working than I make a zillion dollars a year and I have blah, blah, blah working for me. What do you really like to do?...because you might be doing it for the rest of your life (maybe you'd rather run a charter boat operation out of the Virgin Is. than ever see a router or have to deal with some employee's personal problems). Masters in IT is a technology lite degree (big picture), as oppossed to CS degree, EE degree or, for that matter, CCIE (I think). Do you like project management (where can I find someone to solve this routing problem)? Or do you like being up to your ears in detailed, problem solving (how can I solve this routing problem)? Of course, there are always some gifted folks that can do it all. Lastly, advanced education doesn't guarantee you a management position any more than CCIE guarantees you a great networking position, anymore than being someone's boss guarantees you personal satisfaction. There simply are no guarantees. Finally, advise is cheap...just ignore the advice and flip a coin. You've got a 50 percent chance.

CRC errors on Catalyst 3500 XL port
Hi,
I have a 3640 ("router1") with IOS v11.2 which is routing between IP subnets
(class "c" with a one bit subnet mask - using "IP subnet-zero"). There are
two Ethernet ports on the router, each is connected to a separate Catalyst
3500 XL switch. The two switch ports are hard set to 10 MBS, duplex
autonegotiate, spanning-tree on, portfast on. I am seeing collisions and
crc errors on the switch ports that are connected to "router1". The
remainder of the switch ports ( with the exception of a few ports which I'll
explain shortly ) are connected to 100 MBS fastethernet desktops and don't
show any collisions...I understand why.
I also have another 3640 ("router2") connected to the same switches, in the
same manner...for redundancy, I'm told. There are a couple of other 3500 XL
switches cascaded from these...to accommodate the number users. The LAN
size is about 125 nodes with about equal number of nodes connected to each
subnet. I'm new here...I have recommended getting rid of the subnetting
scheme in favor of a classful LAN. Anyway, the switch ports that are
connected to "router2" don't show any collisions/crc errors.
This all started 2 weeks ago. The network has been designed this way for
about a year.
In short, I can't determine whether routing loops are causing the collisions
(and if so, why only on "router1"), or whether there's a port configuration
mismatch between "router1"s Ethernet ports and the switch. Or, maybe some
piece of hardware has just failed? Any suggestions are welcome.

Fw: Cisco Certs Becoming Paper CCXX
This archaic line of thought has been around for ages...in every conceivable organization, since Ally Oop was a fetus...for example, "I had to walk five miles to school every day when I was a kid", or "The old corps was better". Some people are lucky enough to find an employer who will hire a no-nothing and train them into a qualified network administrator. Others aren't...they have to work for certifications and then get employed in the networking field. For most, having a certification just means they are trying to be better (better job, advancement, change careers, etc)what can be wrong with that? In the long run it is always your skill, dedication, perseverance, knowledge, attitude, etc., etc. that get you ahead, not the perceived value of your certification. - Original Message - From: "Mike Davis" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, March 17, 2001 3:51 PM Subject: Cisco Certs Becoming Paper CCXX I will probably get yelled at for this one but...
