RE: New CCNA tracks [7:71256]
CISCO INTRODUCES CCNA PROGRAM ENHANCEMENTS CCNA Offers New Exams for Those Entering Networking Field Today, Cisco Systems, Inc. . announces three enhancements to the CCNA. (Cisco Certified Network Associate) Program which are based on customer feedback, the need for an accessible entry path into the certifications, and upgrades to the exam for addressing emerging networking technologies. As the entry-level certification of the Cisco Career Certifications Program, CCNA represents a strong foundation and understanding of IP networking and troubleshooting. The enhancements include a new two-step exam path for new candidates entering the networking field, revisions to the existing CCNA exam and the option for candidates to apply one of the new exams for CCNA recertification. A Two-Step Approach: The two-step approach introduced in the CCNA program offers candidates the ability to certify at their own pace and skill levels. The two step approach does not replace the existing one exam option, but allows candidates to achieve the certification in two stages by passing a new Introduction to Cisco Networking Technologies (INTRO) exam and a new Interconnecting Cisco Network Devices (ICND) exam to achieve CCNA certification. Given the popularity and success of the CCNA program, we continue to enhance CCNA to meet our customers needs through skills assessment aimed at today's job requirements, said Don Field, senior manager, Internet Learning Solutions Group, Cisco Systems, Inc. The two-step approach offers those new to the networking field the option to test their networking knowledge in stages. The two-certification paths for CCNA include: Passing the CCNA 640-801 exam (available on June 30, 2003); or Passing the INTRO 640-821 exam (currently as beta exam 641-821) and ICND 640-811 exam (available on June 30, 2003). Revisions to the CCNA content: The revised CCNA 640-801 exam replaces existing CCNA 640-607 exam and is designed to better assess the networking skills of entry level candidates. The CCNA curriculum includes understanding the functions and operations of local area networks (LAN), Cisco IOS fundamentals, wide area networks (WAN), virtual private networks (VPN), and Storage Area Networks (SAN). Other topics covered in the CCNA curriculum are IP Addressing, Cisco Command Line Interface (CLI), Routing and Switching technologies and protocols. The CCNA certification content, technology and testing remains focused on real-world skills assessment with labs and exam simulations being key components of CCNA courses and exams. Recertification: The new ICND exam now qualifies CCNA holders for recertification. The CCNA certifications are valid for three years. To recertify, candidates can also pass the new ICND 640-811 exam, the current CCNA exam, or any exam at the Professional or Cisco Qualified Specialist level bearing the prefix 642. The existing CCNA 640-607 exam will retire on September 30, 2003. CCNA: www.cisco.com/go/ccna Cisco Learning Partners are the only source of authorized Cisco training.

RE: 2924 adopting VTP info [7:59074]
Port security is used so that someone can't plug a new device into your network and mess with your VLAN info. That's the purest form of security. A VTP domain password will also prevent an unauthorized switch from learning VTP information however if someone manages to crack the password, your information isn't safe. Remember that VTP advertisements are multicast - so unless a password has been specified for the VTP domain, any device (PC or otherwise) in promiscuous mode will be able to access VTP information. By default, most (if not all) Cisco devices have VTP server mode set as the default. By connecting any new switch to the network, the switch will automatically learn VTP information advertised in VTP messages and self-configure. The behaviour you experienced is expected and by design. -- Leigh Anne PS. Think about how RIP would operate if an unauthorized router running RIP were to be connected to your network.

OT: Begging for help at Telus [7:48429]
For the past 5 days, I've been on the phone for at least two and a half hours trying to get something relatively simple done at Telus. I've spoken with several helpdesk techs, three senior helpdesk techs, have been told numerous times that this is being escalated to the appropriate department for resolution, but somehow I keep getting the senior techs phoning me back instead. I'm hoping someone here would be able to contact the appropriate people on my behalf to get this accomplished. What I want is simple. Telus is sending out a DHCP offer message using its domain name (ab.hsia.telus.net). I'm using a domain name - I have domain name privileges as part of my internet account, and want it sent out instead. It's creating problems because my machine believes it's name is something other than what it should be. I could edit the dhcp script that runs on my Red Hat box, but I'm not a programmer and I'd probably create more problems than what it is I'm trying to solve--and it's always been my philosophy that things should be fixed properly rather than bandaged and forgotten about--which inevitably always seems to come back and bite you in the butt once you've forgotten about the fix you had to implement.

This is done by sending out routing table updates. Periodic updates contain the entire routing table and are sent at pre-specified intervals. Triggered updates are sent after a topology change occurs, e.g., an interface goes up or down; a route becomes unreachable or reachable; or a new route is added. They contain only information on modified routes. To avoid floods of triggered updates in case of flapping interface(s), distance vector routing protocols' implementations limit their frequency (after 1 to 5 s following the last triggered update).

RE: STP and 7 hops [7:44408]
Actually, the 5-4-3 rule has everything to do with detecting collisions. It's a limiting factor of distance so that a collision will be detected within the first 64 bytes of a frame's transmission (also known as Ethernet's minimum frame size). It's preferable to detect a collision before the frame leaves the buffer of the transmitting interface - so that retransmission can be accomplished at the data link layer rather than left to upper layers. Several months ago, Priscilla and I debated the 7 switch rule. If you wanted to search the archives for the entire thread, it was titled What's the diameter of your switched network? [7:17489] and was discussed at the end of August, 2001. Here's an excerpt from one of my posts regarding the 7 hop limit: From other statements I've read (Cisco published material) and from the original excerpt I published, I'd imagine that the placement of the root does matter. Part of this restriction is coming from the age field BPDU carry: when a BPDU is propagated from the root bridge towards the leaves of the tree, the age field is incremented each time it goes though a bridge. Eventually, when the age field of a BPDU goes beyond max age, it is discarded. Typically, this will occur if the root is too far away from some bridges of the network. This issue will impact convergence of the spanning tree. I'd think that if a bridge were to be the third bridge away from the root, and another switch was the third bridge on the far side of the root, I wouldn't expect to see any problems with MaxAge because I can't see the root being too far from some of the bridges in the network. Now if a bridge were to be the seventh, I could see how that would impose a greater delay and possibly negatively impact the MaxAge parameter. Now my question would be... does this really apply in today's networks or is this more of a limitation of yesteryear's software-based bridges? And essentially, that's the conclusion Priscilla and I came to - that the 7 hop radius doesn't really seem to apply to today's switched environments... You might want to check with her again though - Priscilla just authored a new book on troubleshooting campus networks and may updated her thinking. -- Leigh Anne Chisholm (CCNP, CCDP) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Steven A.

Historically, I am not sure why it's 7, but Ethernet has a base hop limit of 4 switches (5-4-3 rule), so it doesn't really matter so much. The reason for the 4 hop limit in Ethernet is simple: For 10 Mb or full duplex 100 Mb connections, the limit is mostly to reduce noise from the amplification of the signal as it passes through the switches/hubs, where as in 100Mb half-duplex connections, it is mostly to keep the propogation delay within specs.

RE: My interview story [7:40553]
Having recently completed the Aircraft Survival game with a room full of fellow pilots, I can't say that the game was able to determine how people thought, but rather, how people acted within a team environment. Does an individual give in immediately when confronted by others? Does the individual draw logical conclusions? Do they integrate ideas of others into their thinking? Or are they stubborn and impose their views on the group? Having done the exercise alone at first, and then as part of a group, my thinking was substantially different than that of what we accomplished as a group - which is to be expected, because we all have different life experiences from which to draw upon. Personally, I thought Macleans magazine would rank high up in survivability importance because of its flammability - but neither my team nor the scenerio designers concurred. Does this mean my thinking is flawed? Heck no! I've watched Survivor - and I've seen how hard it is for the average Joe to start a fire. If I'm stranded, I want to make sure I've got the ability to boil water to keep me healthy while I wait to be rescued. Now because this item was ranked by survival experts as the least important item, does it mean that I lost the game? And what about the fact my fellow team members thought about using locking wire to make animal snares or fishing hooks. I never thought of that. Again--would I be ranked below other candidates that do a little more outdoors survival stuff than myself? Heck no! As I said--the exercise is more about how you function in a group, rather than on what choices you actually made. I can see an employer using this as a tool to discern your ability to fit into a team environment... Likely the interview was done by someone who just went through it and without thinking about the ramifications of doing something like this in an interview situation (who's ever heard of a group interview for a job before?

Oracle too (one possibly apocryphal story - when Oracle was starting out, Oracle would ask a candidates who were coming straight out of college whether he was the smartest student he knew, if the candidate answered 'yes', then the candidate qualified for a round-2 interview, but if the candidate said no, then Oracle would ask then if you're not the smartest student you know, then who is, and then they would try to hire that person). Management consultancies and Wall-Street investment banks are also notorious for this as well.

RE: CCNP exams-The Truth [7:38249]
Actually, I too believe the V2 CCNP exams are too easy - and I don't have years of experience working on Cisco equipment. The sections of the CCNP test I scored highest on were those that I learned the night before, or the day of. Just reading a chapter 24 hours prior to taking the exam was better preparation than skimming chapters of information I knew. Does that make sense? The CCNP questions were based way too closely on the CCNP course guides. I posted a message about this some time back, and said that Cisco was its own worst enemy--it was the one that was creating paper CCNP's as a result. You shouldn't be able to do what I did. Personally, I'm glad the tests are changing--but I'd hope that V3 doesn't have the same fault as V2. And one final point on this... I wrote the old CCNP ACRC exam and found that one to be quite challenging--nothing like the V2 exams. I also found the CCNA exams (V1 and V2) to be more difficult than the V2 CCNP exams. So in summary - posts about the CCNP exams being too easy aren't necessarily big ego issues, but rather in some part, based in fact. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Brian Zeitz Sent: Friday, March 15, 2002 7:00 AM To: [EMAIL PROTECTED] Subject: RE: CCNP exams-The Truth [7:38249] I think what happened was the guy that wrote this got his CCNP after years of hard studying, and working on Cisco equipment. Now he has it, he post that it is so easy so Cisco makes it harder. I am sorry, but a person (not saying me) going for CCNA, it might seem like an impossible task. After all the CCNA covers more areas then some of the other exams I believe. My point is that every exam is hard, depending on the persons experience. Well now you have CCNP, you can post over and over how easy it is instead of helping people in this newsgroup. What are you trying to do, trying to get Cisco to make the test harder so you have job security? Also if the CCNP was so easy for you, probably didn't do it right, because between the 4 exams they cover a lot of material. And a lot of the material is very relivant to the CCIE exams as well. How about you stop posting garbage and post something useful to this group. That's great you got your CCNP and now are looking down on everyone.

RE: TROUBLES-- ISDN simulator from marc russell [7:30763]
You should clue in immediately to the very first probme - Layer 1 status deactivated. You've got a physical layer problem. Look for a cabling issue to be occurring between your routers and the ISDN switch. Traditionally, an NT1 is used to connect an S/T interface to the ISDN cloud (the NT1 provides a U interface for the S/T interface of an ISDN capable device). However... Optsys indicates that if you have a U interface on your router, you require an NT1. This is contrary to the ISDN specs. This is the excerpt of the ISDN faq Marc Russell referenced: Q - My router has a U interface type. What do I need to connect to a Simline2? A - You need an external NT1 And that doesn't make any sense to me. If you've got a U interface, you don't need an NT1 - however again, this is contrary to the Optsys Slimline faq: Q - My router has a U interface type. What do I need to connect to a Simline2? A - You need an external NT1 And that's completely backwards to the ISDN reference points I learned... TE2 - TA | | TE1 - NT1 ISDN cloudNT1 - TA - TE || | | | | R S/T U U S/T R I can't recall this exactly offhand, but I recall seeing something saying don't plug an S/T interface directly into a U interface because damage can result. I think it's in Cisco's documentation for the router--check there for confirmation. If you hooked up things incorrectly, you may have damaged your equipment. Note that you want to use a straight-through cable between the NT1 and ISDN simulator.

RE: Active CCIE? [7:30341]
There are three possible states of a CCIE: Active, Suspended, and Inactive. Active indicates you are a CCIE in good standing - you've met all of the certification requirements. When you first pass your lab, you are an active CCIE for a period of two years. In order to remain active, you must pass a recertification exam within the Active period. If the recertification exam is not passed, your status changes to Suspended. To reinstate Active status, only the recertification exam must be passed (and not the lab). When you pass the recertification exam, your certification will be Active for a period of two years COMMENCING THE DATE THE CERTIFICATION WAS SUSPENDED not not two years from the date of having passed the recertification exam. If you do not recertify within the one year Suspended period, your certification is classified as Inactive. If you are Suspended or Inactive, you're still able to refer to yourself as a CCIE but you must indicate your current certification status so as not to mislead anyone into thinking your certification is up-to-date. Cisco's site provides a bit of information on this... (http://www.cisco.com/warp/public/625/ccie/recertifications/recertification.ht ml#8): 8. What happens if I don't recertify? If you do not recertify by the deadline, you will be placed on suspended CCIE status. Suspended status means that you are not eligible for any CCIE benefits. Loss of CCIE active status means that as an individual you lose your privileges with Open Forum and cannot order CCIE merchandise through Cisco MarketPlace. Until you recertify, you can no longer be counted by your employer as being a CCIE which can effect benefits and discounts. If you recertify while you have suspended status, the next recertification period will be less than 24 months. For example, if someone is 6 months late in recertifying, they will be required to recertify within 18 months rather than the normal 2 years. After one year of suspended status, you will then have inactive status. You will be required to take the CCIE Qualification exam and the CCIE Lab exam to restore your CCIE active status. -- Leigh Anne -Original Message- -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Steven A.

I've got one of the older 2900XL switches that can't be upgraded to the newest 2900XL IOS software. It isn't deeper than any other 2900XL switch I've seen. It also uses a standard console cable - the same that you would use with a Cisco router. My early 2900XL is also IOS-based, and not CatOS nor menu-driven. The 2948G layer 3 switch (and 2980 I'd assume as well although I haven't kept on top of switch releases and this one I'm not familiar with) use CatOS commands but these switches are not part of the XL line. And if I recall correctly, the old obsoleted 2901 switch was also CatOS based (and again isn't part of the XL line). The 2900XL series is funky in that although it does use IOS-based commands, they don't follow the traditional commands - so yes Dennis you are correct.

RE: ZONE Tests vs Boson Tests [7:26639]
As one of CertificationZone's study question authors, I'll attest to what Mike has said - that questions are meant to reinforce key concepts. Yet another exam certification preparation series that follows this same philosophy is Sybex's Virtual Test Center line. The CCNA series has been quite successful - and shortly Sybex will be going live with their new CCNP Virtual Test series. CertificationZone and Sybex are both successful in their product in that people use them to enhance their skills, rather than as a simple way of getting just enough knowledge to pass the exam--and that in turn makes the people who purchase their products more employable because they've got the skills and knowledge to get the job done. In the end, generally it's the person with the knowledge and skills that's going to get the job--rather than the person with a few letters of the alphabet tacked onto their name. So no Shawn, not every test preparation company out there ascribes to that philosophy - but granted, many do. -- Leigh Anne (CCNP) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mike Cinquanti Sent: Tuesday, November 20, 2001 2:47 PM To: [EMAIL PROTECTED] Subject: ZONE Tests vs Boson Tests [7:26639] I'm responding to Shawn's Boson Tests border on Unethical post because CertificationZone.com does market Practice Exams that do help prepare users for Cisco's CCNA, CCIE, and CCNP Routing and Switching tests but we do not ask our Authors to get their questions as close as possible to the questions on the actual exam. Here's why: CertificationZone.com publishes Study Guides that address the key technical topics our users must master to earn their CCNA, CCNP, and CCIE certifications. Each month, we introduce new Study Guides written by experts in the topics they address. The purpose of a Study Guide is to examine and explain the key technical concepts of the featured topic and to provide the reader with tools that can be used to assess their comprehension of that topic. One such assessment tool included in every ZONE Study Guide is a set of approximately 25 Study Questions, written by the same expert. Along with the correct answer, each Question is accompanied by a complete Explanation. Every ZONE Study Question and Explanation is first technically reviewed by a qualified networking professional, then reviewed for grammar and punctuation, and finally undergoes a review for user friendliness. What's the purpose of our user friendliness review? We have a very competent MIS professional who knows just a little about networking read each question and explanation to make sure he can understand what is being asked by the question and explained by the explanation. The vast majority of the over 2,000 questions that feed the ZONE's on-line Exam Engine were, therefore, originally written as Study Guide Questions. And that's the key difference between the ZONE series of Practice Tests for Cisco exams and everyone else's. Instead of helping you memorize, ZONE exams force you to think. Our questions are harder than those you'll encounter on the real test, but they are easier to read and well-explained. We like to tell people who ask about ZONE exams that they learn more flunking one of ours than they will learn passing five of their's. Of course, we're not perfect. We make mistakes. And I'm sure we have questions in our database that are very similar to those you'll see on Boson exams or Cisco's for that matter. But I want to make sure the members of this forum understand that I do not agree with Shawn Kaminski's statement. CertificationZone.com does do things differently than Boson and other Practice Exam providers because we are much more than a provider of practice exams. And I also don't mean to insinuate that Boson does ask their authors to do anything unethical. I only know how the ZONE's Practice Exams are created. It's easy to see what's happening here. All of Boson's tests are done by different authors. Each author is going to try like hell to get their questions as close as possible to the questions on the actual exams, if not right from the exams. Boson doesn't care because they state right in their author contract that they are not responsible for exams that contain questions that break the NDA. The author will be held responsible. It's not like Boson's going to double-check every authored exam for NDA violations. Anyway, the closer the author comes to the actual exam questions, the more exams he'll sell when word gets around that, for example, Boson Test #2 is the one you need to get. However, Boson isn't doing anything different than any other company selling certification practice exams. It's a ridiculously huge, cut-throat, and competitive market out there for study materials.

RE: CertificationZone OSPF I white paper ? [7:23885]
We recently had a discussion on Groupstudy as to where in the OSI model routing protocols existed. Essentially, routing protocols are Network layer entities. To quote from the previous discussion: They are layer management protocols at the network layer. This is not covered in the basic OSI Reference Model, but in the Management Annex to it, and the OSI Routeing Architecture document, both from ISO. Just because a protocol is transmitted using a protocol at layer (N) doesn't make the payload protocol layer (N+1). - Howard Berkowitz If we think about it, there are other examples of this being true besides management protocols. It's pretty common to see the session-layer NetBIOS protocol running on top of LLC, for example. (It's sometimes called NetBEUI in this case, but it still has session-layer behavior.) - Priscilla Oppenheimer Pretty awesome having such resources on the list, eh?

Page 13 presents a table of LSA's type and purpose. Type 2 (network) states that this LSA can be generated by any router. With reference to Doyle, Caslow and RFC 1247 it appears that this LSA can only be generated by the DR for multi-access networks. I appear to have confirmed this also in my lab.

RE: MAC address and VLANs [7:23950]
Actually, that's not correct. The original specification for VLANs from
what I understand mandates that only one VLAN can be assigned to a port, but
manufacturers such as 3COM decided to do otherwise and support multiple
VLANs per port. Cisco responded by creating (on certain switches such as
the Catalyst 2900XL) an administrator to configure a port to be a member of
more than one VLAN at a time when using a membership mode known as
Multi-VLAN. A Multi-VLAN port can belong to up to 250 VLANs; the actual
number of VLANs to which the port can belong depends on the capability of
the switch itself. Although the concept is similar, this membership mode is
different than trunking. The caveat to this feature is that the
Multi-VLAN membership mode cannot be configured on a switch if one or more
ports on the switch have been configured to trunk.
For more information on this feature, search Cisco's website using the
keyword phrase switchport multi.
As for answering NetEng's question--I can't quite determine where multiple
MAC addresses share the same switch port. Could you identify which switch
that is?

RE: a question from lan switching book [7:23764]
Think of it like this. Shared is as many people in a 10 foot by 10 foot room as you can stuff. The size of the room can be an analogy for the bandwidth of the network and the number of people in the room are analogous to PC's connected to the shared bandwidth. The rules of conversation are this: You can only talk if you perceive that no one else is talking. If you hear someone else talking, you must stop immediately, and wait a random period until you are able to try speaking again. Of course, before you begin speaking, you must determine whether someone else is speaking. That's shared bandwidth. In this environment where only 1 PC can speak at a time, that PC is able to use the entire bandwidth of the pipe to send one frame. That frame travels at 10 Mbps. Each PC however must pause briefly between sending frames in an effort to let others talk... Now just because you have 10 PC's, each PC won't necessarily have traffic to send when all 9 others do. Thus, never make the comparison that if you have 10 PC's, on a shared 10 Mbps link, that each PC has 1 Mbps of bandwidth. Not true. Each PC has the ability to use 10 Mbps of bandwidth just like each person has the ability to speak in our 10 foot by 10 foot room--but as the number of people in that room increase in their desire to speak, the ability of others to get a word in edgewise decreases. The more PC's, the more difficult to utilize that shared bandwidth. Now the term switched is also known as dedicated. Switched is a point-to-point link between the connected device and the switch. Think of it like our telephone system. I'm able to pick up my phone and dial whomever I like. When I lift the receiver, I have a dialtone. I couldn't care less if my neighbor is on the phone--I have a link to the telephone company's central office. I don't care who my neighbors are talking to. I don't hear that conversation. I can use as much of my bandwidth as I have available because I've got a dedicated, point-to-point link between myself and the telephone exchange (aka in networking terms, PC and LAN Switch port). Now let me throw a bit of a curve into this discussion. In a half-duplex switched environment, just because I'm able to use the full bandwidth between myself and the telephone company's central office, that in itself doesn't guarantee that my call will get through. Switched networks operating in half-duplex mode are able to suffer from collisions. If I try and phone my mom at the same time some goofy telemarketer does, our phone calls collide. Likely, I get a busy signal. In a full-duplex environment, this type of collision won't occur. One of us will get the answering service which will take a message, forwarding it when the line becomes free. In the full-duplex switching world, the switch buffers the traffic, forwarding it when the destination port is available. To go on a bit of a tangent here... Now of course, the telephone company only has a limited number of circuits that it can carry at one time. In networking terms, this is known as the capacity of the backplane of the switch. The switch is not able to forward unlimited traffic rates. For example, the Catalyst 5000 series switch can only forward 1.2 Gbps of traffic at any given time. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, October 22, 2001 9:57 AM To: [EMAIL PROTECTED] Subject: RE: a question from lan switching book [7:23764] is shared means that there is a 10M ethernet, if there are 10 station in this network, every station has the 1M? or is shared means that there is a 10M ethernet, if there are 10 station in this network every station has the 10M bandwidth when you transmisstion, (csma/cd) after this station trasmisted, another can transmit and has 10M bandwidth. which is right? thanks for answered :) Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=23788t=23764 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: DHCP communication [7:22272]
Priscilla, I'm wondering if you caught part of your trace? Specifically this part: Requested IP AddressDHCP Option Option Code:50 Requested IP Address Option Length: 4 Address:36.1.1.2 It's not common knowledge that DHCP has an option to request the IP address during the original IP address request used the last time the end-host was on the network.

In one of our previous tirades ;-) about DHCP, I sent the following message, which includes a DHCP Discover relayed by a router near the end.

Notice that the packet is a unicast, rather than a broadcast. Also, notice at the IP layer that the source address is the router, not the client's 0.0.0.0 address that you normally see with DHCP. The router also put its address in the DHCP server under Gateway IP Address. The DHCP server needs to see this to know which subnet the client's request came from.

The reason that show int only displays the IP encapsulation is the same reason that only the IP address (and mask) are displayed, not all layer three addresses -- history. The cisco (sic) product line started out as only an IP router, so all displays and config commands were understood to apply to IP. As bridging and other routed protocols were added, the old commands and displays remained the same for backward compatibility. E.G., the command to change encapsulation for IP is just encapsulation __, not ip encapsulation __.

I'm not sure, but I think we're talking semantics here. I think what you're referring to is that the Ethernet types you reference for Novell are based on standards... but if I remember my Novell history correctly, Novell's encapsulation types aren't the standards as we know them. For example, Novell guessed at what the standard was going to be for 802.3 and missed. Novell's 802.3 had scalability issues and as such, had to create 802.2. Now 802.2 by itself isn't an encapsulation type in the IEEE world now is it? And that's what I mean when I say that they're proprietary--they're Novell's own design and naming structure.

RE: Orange lights on Catalyst 2900XL Switch [7:22109]
I know with the defective 1900 I had, the ports that I had that were bad also turned the system LED orange as well. I suspect the 2900XL would do the same if that were the problem. What you likely have, is a case of a Spanning Tree loop. The ports are disabled because of a loop. Check your spanning tree protocol information to see if that's the case. Alternatively, the ports could have been disabled due to an address violation - but because of the hubs, depending on how you've got them connected, I suspect you've got a loop. -- Leigh Anne -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Patrick Ramsey Sent: Thursday, October 04, 2001 3:42 PM To: [EMAIL PROTECTED] Subject: Re: Orange lights on Catalyst 2900XL Switch [7:22109] I believe in this case, the orange represents halfduplex Rizzo, Damian 10/04/01 05:28PM Hey all, I have a quick question regarding a Catalyst 2900XL Switch.

As a follow up to my previous comments about CCIE lab equipment... Cisco says that yes they will be replacing the Cat 5000's some time in the future and will post a notice beforehand. When that's to occur, I don't think even they know but it's definitely not October 1st. They've also indicated that there will be no PIX on the routing and switching exam.

Will I need to prepare any differently for the new format exams? No. Only the format of the exam itself has changed. The knowledge and skills required to pass are the same in the old and new formats.

The answer according to the people I've emailed at Cisco is that the number is yours. If you recertify, you get it back. The other question I asked Cisco was about whether you could call yourself a CCIE if you have a status of suspended (your two years has elapsed and you're in the 1 year grace period to complete the recertification exam) or inactive (you've failed to successfully complete the recertification exam). Again, the answer I received was that once you're a CCIE, you're always a CCIE. You must however clarify your status so that you don't mislead anyone. If you're inactive, you must clarify that fact.

RE: which layer BGP,RIP ,OSPF work on [7:21226]
Very simple answer. The one thing that's always stressed with respect to the OSI model is that many protocols were developed prior to the OSI model being published. TCP/IP is one of those protocol suites. The OSI model serves as a guide for understanding how protocols work, or for how to develop new protocols or protocol suites. It is not a hard-and-fast rule where protocols must conform to the definition of each individual layer. -Original Message- From: Tribavan Raina [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 7:51 PM To: '[EMAIL PROTECTED]' Subject: RE: which layer BGP,RIP ,OSPF work on [7:21226] OOK.

RE: Cisco NP-1FE and MC3810 $500/ea [7:20574]
Neal, perhaps PayPal is the cause of your problems. If you're selling to international bidders that haven't yet signed up for PayPal, it's almost impossible for the buyer to be able to send any reasonable amount of money within a short time period. PayPal verifies international bidders by charging $1 to their credit card. If the card information is good, the $1 charge appears on individual's credit statement. The verification system requires the ID number associated with PayPal's name that appears on the statement. Once the verification number has been entered, the $1 charge is reversed and the credit limit is lifted. I signed up August 25th. PayPal's charge missed the cutoff on my last credit card statement, so I've got to wait for my next statement. PayPal has indicated if you contact your credit card company to get the information, PayPal will turf your account. I've recently won an auction and I need to pay for my equipment. I've contacted them about manually verifying my account but that takes up to 10 business days. They know my credit card is good because I've had an unverified US account for over a year linked to my Aunt's address that I've charged several hundred dollars to over several transactions but because the US account is not linked to a US bank account, I don't have much of a limit left (a few hundred dollars). PayPal simply isn't worth the hassle and most sellers aren't interested in waiting four... five... six weeks for payment. I've even tried calling PayPal's long distance number (no, not even a 1-800 number) so that I can speak with someone to get this resolved, but their system keeps disconnecting me when I'm waiting for customer service. This has happened repeatedly. As an aside, PayPal doesn't advertise anywhere on their site a telephone number to contact customer service. To me, PayPal wins the anti-customer service of the year awared. If you're not signed up for BillPoint, I'd recommend you do so. You can send or receive money as soon as you create an account--no bank account information required, no credit card verification process that takes weeks and weeks. Granted you do have a limit for receiving money (I think it's $500 for auction, $250 for simple transfer) but BillPoint lets you send multiple transactions so you can receive the full amount. You might have better luck if you go that route. And oh yes--BillPoint is just as friendly to international customers as American customers. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Neal Rauhauser Sent: Thursday, September 20, 2001 5:32 PM To: [EMAIL PROTECTED] Subject: Cisco NP-1FE and MC3810 $500/ea [7:20574] I apologize for the commercial spam :-( I've got an NP-1FE and an MC3810 /w 32d/8f - I don't need 'em, they've been hanging around for months, and my last three ebay bidders have not paid.

RE: Cisco Certifications for Sale ? [7:20747]
People cheat in Pakistan. People cheat in Canada. People cheat in the United States. Should Cisco deny testing these countries too? No. Will Cisco be able to stop people from cheating? Not likely. Certifications are a way to get your foot in the door. If an employer isn't smart enough to ask technical questions during an interview to weed out the people that haven't learned what they need to get the job done, then they deserve what they hire.

Well I completed my CCNA in January and this is really amazing that the guy knows nothing as when it came to implementation. Everytime he goes back to refer his books and come with hazzy and undetermined solution. I was wondering that how has he got his certifications and when I asked him personally he admitted that in Pakistan they can pay money and can sit with someone and take help of books and clear the exams. Can you imagine this person score in CCNA was 980. If this is the case then I think Cisco and other companies should take off their testing centres in Pakistan so atleast this should be in favour to us who put their days and time in getting such certifications.

I have worked very hard to achieve the CCNA, CCDA, CCNP and CCDP and now I am working even harder to prepare for the CCIE Lab. I would be highly upset to discover that Cisco is tolerating this.

This one's very bad as it overwrites files with various .eml files, typically seen is readme.eml. If you do a search on the local drives for the extension, you will find numerous files (over 1600 in my case last night) found. How does this relate to Cisco? Well, I was originally called for a router problem as the Internet browsing and email transfer was very slow and of course the client's first thought was that there was a telco, router, DSU, etc. issue. I checked the router and the console (and VTY) was VERY slow. I ran a show processor cpu and discovered the processor utilization was nearly 100% and was staying there, which explains why the console was so slow. Upon deeper scrutiny, I found that IP input was the process using most of the processor, which indicates that IP traffic is jamming the router. With this knowledge, I went after the worm, which unfortunately, has no simple fix, at least at this time. When I removed the server from the network, the router was fine.

Mike Braun First American CREDCO -Original Message- TruSecure ALERT- TSA 01-023 - W32.nimda.a.mm Date: September 18, 2001 Time: 1000 EDT RISK INDICES: Initial Assessment: RED HOT Threat: VERY HIGH, (rapidly increasing) Vulnerability Prevalence: VERY HIGH, effects IIS servers version 4.0, 5.0, and internal networks. Cost: High, command execution is possible Vulnerable Systems: IIS 4.0 and 5.0 SUMMARY: A new IIS worm is spreading rapidly. Its working name is Nimda: W32.nimda.a.mm It started about 9am eastern time today, Tuesday,September 18, 2001, Mulitple sensors world-wide run by TruSecure corporation are getting multiple hundred hits per hour. And began at 9:08am am. The worm seems to be targeting IIS 4 and 5 boxes and tests boxes for multiple vulnerabilities including: Almost all are get scripts, and a get msadc (cmd.exe) get_mem_bin vti_bin owssvr.dll Root.exe CMD.EXE ../ (Unicode) Getadmin.dll Default.IDA /Msoffice/ cltreq.asp This is not code red or a code red variant. The worm, like code red attempts to infect its local sub net first, then spreads beyond the local address space. It is spreading very rapidly. TruSecure believes that this worm will infect any IIS 4 and IIS 5 box with well known vulnerabilities. We believe that there are nearly 1Million such machines currently exposed to the Internet. Risks Indices: Vulnerability VULNERABILITY PREVALANCE is very high - Milllions of Internet Web server hosts: TruSecure process and essential configurations should generally be protective. The vulnerability prevalence world-wide is very high Threat - VERY HIGH and Growing The rate of growth and spread is exceedingly rapid - significantly faster than any worm to date and significantly faster than any variant of Code red. Cost -- Unknown, probably moderate per infected system. The worm itself is a file called README.EXE, or ADMIN.DLL a 56K file which is advertised as an audio xwave mime type file. Other RISKS: There is risk of DOS of network segments by traffic volume alone There is large risk of successful attack to both Internet exposed IIS boxes and to developer and Intranet boxes inside of corporations. Judging by the Code Red II experience, we expect many subtle routes of infection leading to inside corporate infections. We cannot discount the coincidence of the date and time of release, exactly one week to (probably to the minute) as the World Trade Center attack . REPLICATION: There are at least three mechanisms of spread: The worm seems to spread both by a direct IIS across Internet (IP spread) It probably also spreads by local shares. (this is not known for sure at this time) There is also an email vector where README.EXE is sent via email to numerous accounts. Mitigations TruSecure essential practices should work. Block all email with EXE attachments Filter for README.EXE Make sure IIS boxes are well patched and hardened, or removed from both the Internet and Intranets. Make sure any developer computing platforms are not running IIS of any version (many do so by default if either.

RE: A plan to rebuild.... [7:19611]
Perhaps you haven't noticed, but Canada pretty much has an open door policy
letting in anyone who wants to come here. You claim refugee status and then
you're permitted to leave your entry point unescorted, unmonitored. The
substantial number of those people never come back to finish being
processed. It's during that processing period many known terrorists are
identitfied and by then it's too late. They've disappeared into the fabric
of our country. Canada is home to a substantial number of terrorist groups
and I hope knowing that makes you feel comfortable.
Where there is a will there is a way, and yes they would have found another
way into the US - but Canada makes it far too easy for that sort of thing to
happen. That's why the US needs to slap Canada's parliment upside the head
for its immigration policies.
Simply put, this is my last public post on this topic. I won't discuss it
again. Groupstudy isn't meant for this type of discussion, but I think it's
important that people in the US know about what goes on in the country that
borders them to the north. The Canadian public has tried for years to get
immigration policies tightened, unsuccessfully. Perhaps the Americans can
help.
And finally, your comments weren't very appropriate for this type of list.
Such behavior doesn't really reflect well on Canadians, now does it.

I guess you're not aware of Canada's reputation as being a haven for
murderers and terrorists. Once these people are here, we can't deport
them
because of goofy Canadian politics. When these people come into Canada,
Canada has a responsibility to ensure these people don't have
undesirable
backgrounds. Then when they're here, it's easy for them to get forged
documents indicating that they are Canadian citizens. That makes the US
immigration department's job more difficult because of the free flowing
policy of letting Canadians pass through the US border with a minimum of
background checking. It's the freedom that Canada enjoys with the US
that's
at risk unless our Government steps up to the plate and tightens things
up.
How often have you heard after the fact that Canada Immigration didn't
investigate into people's backgrounds properly? Far too often
I'm afraid.
It wasn't the Canadian immigration department that stopped the

RE: A plan to rebuild.... [7:19611]
I guess you're not aware of Canada's reputation as being a haven for
murderers and terrorists. Once these people are here, we can't deport them
because of goofy Canadian politics. When these people come into Canada,
Canada has a responsibility to ensure these people don't have undesirable
backgrounds. Then when they're here, it's easy for them to get forged
documents indicating that they are Canadian citizens. That makes the US
immigration department's job more difficult because of the free flowing
policy of letting Canadians pass through the US border with a minimum of
background checking. It's the freedom that Canada enjoys with the US that's
at risk unless our Government steps up to the plate and tightens things up.
How often have you heard after the fact that Canada Immigration didn't
investigate into people's backgrounds properly? Far too often I'm afraid.
It wasn't the Canadian immigration department that stopped the guy heading
into the US to blow up LAX on the millenium... it was the US immigration
department.

Two telephones have two telephony links... and they can be linked together using a bus... but without POTS service, they can't call each other, can they.

RE: Is this going to be a trend for the CCIE cert??? [7:19296]
I guess someone ran across Larry Seltzer's article in Fortune Small Business... Doesn't this get us back to the discussion where I stated that experience isn't necessary the be-all and end-all of answering the question, Who's the best? My point (and I'll say it again) is that experience doesn't always matter. Brilliance and the willingness to do a good job can compensate quite well for experience. If there's a firm out there that's looking for a specific block of CCIE's and isn't willing to interview a person because their CCIE number is from the wrong block, then that's a firm you don't want to work for. They're not selecting the best candidate for the job--but rather the person that looks best to a client. I can show you one CCIE right now that is in the 2000 range that I don't think has got half the skills of Tony Medeiros - CCIE #6172. And that is that organizations loss... No skin off my nose...

RE: One Journalist's Opinion of CCIE [7:18843]
Sorry, I haven't seen the movie Rainmaker. As for your experience in the Air National Guard--you know that experience doesn't mean that you never make bad judgements. I can think of several extremely seasoned pilots I know that have made really dumb judgement calls just because they've pushed the envelope before and not had any consequences. And sometimes, it's not even having pushed the envelope before that leads to stupid mistakes. One pilot I knew began flying during I believe it was the Korean war. He moved onto airlines and racked up several thousands of hours flying the friendly skies. He was also a seasoned aerobatic pilot having won several U.S. aerobatic championships and helped lead the US team to win a World Aerobatic Championship title. He and his wife wanted to sell their land in southern California. They hired a photographer to take pictures of their property. When the photographer didn't show up, this pilot grabbed his wife's biplane and in a tempermental state took pictures of his own property. Needless to say, distances looking through the lens of a camera are different than standard vision. He flew into a hill on his own property. I can't say that I as a young pilot compared to this veteran haven't made stupid mistakes, but I would take far fewer risks than he would. To every rule there is an exception--because people are individuals. Some are able to compensate. The best person you'll ever know is the person who says, I don't know, but I'll find out. And then they do. THAT's what I mean when I say My point is... experience doesn't always matter.

Question about Cisco's Hierarchical Model [7:19069]
I've been going through the BCMSN course and I'm a bit baffled on how to do something. There's the statement that: Because VLANs terminate at the distribution device, core links are not trunk links and traffic is routed across the core. What I'm puzzled by is how to terminate a VLAN at the distribution layer. What am I missing here?

Yes, a single device can represent the core and distribution layers. That's your typical collapsed core. However, what of a link between two collapsed core devices. If it's not a trunk link, how does it carry traffic that originated in a VLAN? How do you truly terminate the VLAN at the distribution layer?

RE: Question about Cisco's Hierarchical Model [7:19069]
Chuck, that's an excellent point. I've been thinking in terms of Campus core, but Daniel Cotts reference applies to an Enterprise core. And I think what he had to offer definitely works. If that's what Cisco meant, then does that mean that the hierarchical model only applies to enterprise networks and not campus environments? I've been thinking campus core because the beginning of The Building Block Approach section of the BCMSN courseware talks about network building blocks being any one of the following fundamental campus elements or contributing variables. Campus Elements: Switch block, Core Block. They're talking about a campus network environment--and in that type of situation, I don't quite see how to terminate VLANs at the distribution layer. -- Leigh Anne PS. Where's Howard?

It started on Friday with visitors on Verizon DSL waiting forever for pages to load. Yesterday and today PacBell DSL and some Netcom customers started complaining. This only seems to occur on HTTP traffic. If we have the visitors try HTTPS the pages load fine (with the normal encryption slowdown). We've looked at Layers 1-4, and can't see any problems, ping looks great, interfaces and cpus on routers, servers and switches look fine. It's almost like it's a transparent cache bug. Anyone know if Inktomi, or any major cache vendors rolled out any new code this week? For that matter does anyone know what caches Verizon and SBC use for starters?

RE: Can you pass CCNP w/o having Cisco gears? [7:18124]
When I was hired at a law firm as Manager, Voice/Data Systems, several lawyers thought of me as the head word processor. Two of the previous three individuals that held the position of Manager, Systems (data only) were women who came up through the ranks and were in Word Processing beforehand. One lawyer I remember got quite upset when I wouldn't update his resume. I told him I'd pass it on to WordPro. That was met with quite a fury... Simply put, I had other things to do. I had a frame relay network to get up and going, I had two PBXs that required major Y2K upgrades, I had a wiring closet that was a complete nightmare and needed to be cleaned up, and had renovations of a remote location that had to be completed. And that's just Monday's tasks... Once I hung a few certificates on my office wall, attitudes towards me changed quite quickly. I was especially fond of my Voice Engineering and Design course certificate. Likely it was a combination of what I hung on my wall that gave me credibility, but it also was the fact that I had a spine. Just because someone went on a tirade wasn't a reason for me to drop my responsibilities and take on the task that was better done by someone else.

If you hadn't, and hadn't provided me with the information for me to remember the correct answer, I would have posted it.

[7:18232] this post results from an off line conversation with someone regarding multicasting. The original question follows: someone said: CGMP: Router sends CGMP multicast packets to the switches at a well known multicast MAC address: 01-00-0C-DD-DD-DD. Now by definition, if all multicast frames have a destination MAC address beginning with 01-00-5E - how does this address qualify as multicast? I got this from http://www.cisco.com/networkers/nw99_pres/314.pdf a networkers presentation. I've found other documents that reference this MAC address--but is this really considered a multicast address? end of quote let's see - unicast is intended for a single destination, broadcast is intended for all destinations. does that mean that anything intended really or potentially for more than one destination, but not all destinations, is a multicast? I have the distinct impression that some folks somewhere are playing a bit fast and loose with definitions. Is the spanning tree reserved mac 01-80-C2-00-00-00 multicast? it can't be broadcast because it is not destined for the FF mac. How about the token ring error monitor mac of 03-00-00-00-00-10 ( this is the ethernet form of the address, according to my source ) Is CGMP really multicast? As opposed, maybe, to an ethernet frame placed onto the wire ( or issued out all ports ) for a specific purpose? Cisco's own definition of multicast, Single packets copied by the network and sent to a specific subset of network addresses leaves a lot of wiggle room. is Cisco talking about layer three network of layer two network? not that Cisco's definition is necessarily related to industry standard definitions, as we all know from the numerous discussions about OSI here.

Pass your lab, get your number, call yourself a CCIE. Til then, you are a CCNP, CCDP. My two cents. CL: about the same time the CCNP 2.0 became a certification.

Having recently just passed CCNP this year I will say you must have a Router. The reason is that the prescribed rituals must be performed in front of the Router. Without a Router the powerful spirit of routing, BGPOSPF, wont bless your efforts and even if you do pass all knowledge will be removed from you within 2 months. Some have said scrificing your most valuable possesion before the router helps. I give it my time which seemed to work well. Others have given the Router spirit money, bought it accessories, even food but so far time works best.

RE: Multicasting - means what? [7:18232]
That happens to be the page I've been looking at--that generated my query in the first place. I've looked and looked, and can't seem to find a reference for 01-00-0c-ee-ee-ee either. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Chuck Larrieu Sent: Sunday, September 02, 2001 6:54 PM To: [EMAIL PROTECTED] Subject: RE: Multicasting - means what? [7:18232] you know, Leigh Anne, I recall seeing a CAM table in one of the documents I checked while I was researching you question. check out http://www.cisco.com/warp/public/473/22.html if you scroll down about half way, and look over the CAM table. Lo and behold, the spanning tree, CGMP, and CDP MACs are there, appearing in each of the vlans. there are a couple of other suspicious looking MACs there as well, but I can find no information referencing them. oh wait.

[7:18232] Heck no Chuck... I don't mind you bringing it up. I think it's an interesting discussion. If you hadn't, and hadn't provided me with the information for me to remember the correct answer, I would have posted it. At any rate... with respect to your public and private emails to me: When CGMP is enabled on a switch, the switch adds the MAC address 01-00-0C-DD-DD-DD to its cam system table. By default, a switch only listen to multicast addresses in show cam system. I'd expect to see the MAC multicast address for Spanning Tree to be in there as well as you suggested in the private email. I believe that 01 is reserved for all multicast addresses. It's just that 01-00-5E-00-00-00 through 01-00-5E-7F-FF-FF have been reserved for IP multicast translation as you said in a private email to me. I don't think anyone's been playing fast and loose with this one. Just you and I had a blonde moment. Don't know about the Token Ring address for sure... I've **GOT** to get working on my current project because I'm **WAY** behind. But if you read it right to left, I see the first octet as 01... -- Leigh Anne -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Chuck Larrieu Sent: Sunday, September 02, 2001 9:48 AM To: [EMAIL PROTECTED] Subject: Multicasting - means what? [7:18232] this post results from an off line conversation with someone regarding multicasting. The original question follows: someone said: CGMP: Router sends CGMP multicast packets to the switches at a well known multicast MAC address: 01-00-0C-DD-DD-DD. Now by definition, if all multicast frames have a destination MAC address beginning with 01-00-5E - how does this address qualify as multicast? I got this from http://www.cisco.com/networkers/nw99_pres/314.pdf a networkers presentation. I've found other documents that reference this MAC address--but is this really considered a multicast address? end of quote let's see - unicast is intended for a single destination, broadcast is intended for all destinations. does that mean that anything intended really or potentially for more than one destination, but not all destinations, is a multicast? I have the distinct impression that some folks somewhere are playing a bit fast and loose with definitions. Is the spanning tree reserved mac 01-80-C2-00-00-00 multicast? it can't be broadcast because it is not destined for the FF mac. How about the token ring error monitor mac of 03-00-00-00-00-10 ( this is the ethernet form of the address, according to my source ) Is CGMP really multicast? As opposed, maybe, to an ethernet frame placed onto the wire ( or issued out all ports ) for a specific purpose? Cisco's own definition of multicast, Single packets copied by the network and sent to a specific subset of network addresses leaves a lot of wiggle room. is Cisco talking about layer three network of layer two network? not that Cisco's definition is necessarily related to industry standard definitions, as we all know from the numerous discussions about OSI here. Any comment? Are we counting angels again? :- Chuck P.S. I hope the person who brought this up in private correspondence doesn't mind my posting here.

RE: DSL / Cisco Switches [7:18269]
I'd forget looking at the switches as being the problem. You're able to get traffic through because you indicate you're able to get the name resolved to an IP address. You need to look at your addressing scheme. How are all the end-hosts being connected to the internet? Are you using internal addressing and NAT? Or does each computer obtain its IP address via DHCP? Best way to troubleshoot this problem is to diagram your addressing and routing scheme. I've got a strong suspicion I know exactly what your probelm is... -- Leigh Anne -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Pierre-Alex Sent: Sunday, September 02, 2001 7:59 PM To: [EMAIL PROTECTED] Subject: FW: DSL / Cisco Switches [7:18269] I have tested the scenario below with two switches: a Cisco 1912XL-EN and a 2924XL-EN In both cases I had the same results.
