CIT question
Hi all, I am reading for the CIT exam and I saw something in the book that seems alittle bit strange: It says that in the sh int serial 2/3command the bandwidth = parameter is used to compute IGRP metrics only. Does this means that we don't care (if we don't play with IGRP) what is = the speed=20 of the connected line? Lets say that if we have an E1 line and the BW is = 256kbps, the interface will play on 2048kbps ? I think that it will play on 256kbps. I am a little bit comfused.

Re: CIT question
Your assumption is correct: the "bandwidth" parameter has no bearing on the actual speed of the line. If your provider is giving you 256k, then you'll run at 256k. However, the router will *assume* that you're running at T1 speed by default, and will use that bandwidth (1.544mbps) in its (E)IGRP metric calculation. To show how this works, don't set your bandwidth parameter, and look at your metrics. Then change your bandwidth to 256k, and your metrics will jump astronomically.

RE: Log message from Cat4006
Hi The message you see on the cat4000 means that the catalyst saw a frame with a null source MAC address and informs you that it will not learn that MAC address and thus not add it into the CAM table. These messages are not displayed on cat5000 because the necessary code for displaying them is not there. Possible causes for having a NULL mac address: a smartbit sending such frames, a router or station which MAC address has been modified or sometimes other vendor switches use such null MAC address as source MAC address (3Com for instance). If none of the above causes apply to your network, the only ways to remove these messages are: 1) use a sniffer to find out which machine is sending such frames 2) change the logging level so the messages are not displayed anymore. This only clears the logging but does not resolve the exact problem (it only masks it). You can change the logging level by using the following command: set logging level sys 3 Regards, /Stuart - | | Stuart Potts ||| ||| Customer Support Engineer .|. .|. .:|:.:|:.Phone: (44) 1908 203478 c i s c o S y s t e m s Email: [EMAIL PROTECTED] "Empowering the Internet Generation" - -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Lim Kok Hua Sent: Wednesday, February 14, 2001 9:47 AM To: [EMAIL PROTECTED] Subject: Log message from Cat4006 Hi Anyone can advise on the following message from a Cat 4006 switch ? %SYS-4-P2_WARN: 1/Filtering Ethernet MAC address of value zero from agent host table interface _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

I've never used Zebra but it sounds like if you had some existing equipment and wanted to expand on that, couldn't afford to buy another router but had some old PC's it would be the way to go, since speed/reliability wouldn't be a real factor in a home lab. Any thoughts?

A Cisco 3640 router would cost about the same and I'd like to see you get a full BGP table with Linux for the same hardware cost. plus, linux doesn't have CEF or any of the standard stuff that comes with IOS (or JunOS for that matter). The SMB market does what they will, and who cares anyways? They have *no* market share, they aren't Internet players, they aren't market players, they are NOTHING. what they DON'T NEED is another strange weird solution that I would only put into a lab ; they need something standard, something that works, something that will scale, something that will perform up to their needs, and something that most $20/hour NT admins could configure. I am all for (ok not for Linux, but for FreeBSD maybe) an open source OS for research or inside a lab where others are familiar with it. But suggesting Linux routers for a SMB (or Enterprise, or Service Provider) in a production, real environment is insane. Don't get me wrong, I like Zebra, it's a good tool. But I would never run it if my mom and pop needed a "router" solution for their new cybercafe. The "correct" solution for SMB is a 1600 or 1700 series router. For what you say "most" SMB's a 1605-R (Single WAN, Dual Ethernet) and two Catalyst 1900 switches would be more than sufficient and would cost less in time/effort alone for the initial setup. Choose one person out the 165,000 CCNA certified people, and I'm sure at least 90% of them could configure this environment for 802.1Q, HSRP, remote management, NAT, Firewall (Secure Integrated Software built-in to the router), or VPN (IPSEC, L2TP, PPTP/MPPE). That's what they are trained to do. Show me a Linux certification or training program that discusses T1 cards or Zebra installation/configuration. And then give me some numbers...

Fw: Is this COOL or what? Cisco Space Phones!
Received this today from my inside sales manager. Though you "might" consider blowing your own horn - it is still cool. Kevin Wigle - Original Message - From: "Will Cox" [EMAIL PROTECTED] To: Recipient list suppressed Sent: Wednesday, February 14, 2001 9:15 AM Subject: Is this COOL or what? Cisco Space Phones! Enjoy the read!! Yesterday, at approximately 4:09 PM Central, the first phone call from space was made. Astronaut Marsha Ivin, using a Cisco IP SoftPhone on the Space Shuttle Atlantis, made the first and second telephone calls EVER from space. NASA has had CallManager software in a development lab since prior to the Selsius acquisition by Cisco. The Selsius, and now second-generation Cisco phones, have been unusually tolerant to the satellite delay between Mission Control in Houston and the Shuttle. Brett Parrish, lead NASA engineer on this project, holds our CallManager software in very high regard, especially since finding it works over satellite delay without modification between our hardware-based phones (tested to up to 1.2 seconds of delay). Brett has stated that it is very unusual for an application to work out of the box with this type of delay. Since certification for flight is an extremely long and, at times, extremely political process, NASA decided to use SoftPhone for the first trial. The main reason for this is that the laptop PCs used by NASA astronauts have already been certified, and getting a software process in flight is much easier than launching hardware. Extensive testing was performed at NASA using custom-built equipment to replicate the delays and LOS (Loss Of Signal) conditions common with the Space Shuttle. Minor modifications were made to CallManager (inclusion of a service parameter) and to SoftPhone (change in the order of events for call acceptance) by Cisco development to address TAPI issues with delay, and SoftPhone was approved for a trial flight. Unfortunately, this was not an official goal of the Space Shuttle Atlantis, which simply meant testing was not scheduled, and not guaranteed. Despite the lack of official stature for this test, optimism that SoftPhone would be tested was very high as the Astronauts had seen the application and were demanding that it fly with the Shuttle. Imagine being out in space with no way to call home! Imagine being IN space and being able to make a normal phone call anywhere! Despite all the technological advances, separation is very apparent when out in space. Never has an Astronaut been able to pick up a phone and place a call. At approximately 4:00PM Central the opportunity to make a call using the Cisco IP SoftPhone became available. Marsha Ivin, with a brief break in official tasks, asked Space Command if there was time to try the IP SoftPhone. The Flight Commander gave the go-ahead and the test was on!. Marsha booted up the SoftPhone and at approximately 4:09PM made a call to the Flight Director. The call went from her SoftPhone software through a VG-200 gateway, over an FXO port, through a PBX to the phone on the Flight Director s desk. They held a long and animated conversation (though what was actually discussed is unknown) and at the end Marsha was granted permission to call one of the 7960 phones in the POC (Payload Operations Center). She made the call and it was answered by Brett Parrish. Marsha asked So how do you like getting the second ever call from space? . After speaking with Brett, Steve Schadelbauer of NASA was put on the line and he spoke with Marsha. The conversations with Marsha lasted for several minutes. Both Brett and Steve commented at how clear the conversation was much better than the audio quality found on the radio conversations with the Shuttle. It was amazing at how much of a non-event this was. History in the making but no scrambling, no trouble-shooting. IT JUST WORKS !!! Most of the credit goes to Brett and Steve for their tireless testing and replication of the Shuttle s environment. On the other hand, this is truly an illustration of how Cisco s IP Telephony makes geographic location irrelevant to audio communications. Anywhere, and that means ANYWHERE, you have IP connectivity you have a COMMUNICATIONS network, which includes telephony. The network works, no excuses! This is a tribute to many things. Brett and Steve put our software and hardware through the ringer at NASA subjecting it to delay, loss of signal, and bit error rates well above what would be found even between Mission Control and the Shuttle. As a result, this historic moment was a non event. Also as a result, future applications are so real that only official testing and approval stand in the way. We have successfully tested 7960 phones in the Space Station and in the Shuttle and they work better than the SoftPhone. It will be a while before we see them as mission approval is a long, and yes

RE: DISTURBING: Spanning Tree Protocol Does not Work.
Hi Pierre, You still need to finish setting up trunking on the 2924XL to see if my theory is correct. The two Catalysts on the segment between Port B on the C1912 and Fa0/21 on the 2924XL don't seem to be talking. So Port B shows that it knows who the root bridge is, but it shows itself as the designated bridge since it sees itself as the only switch on that segment and thus the only way to get to the root. One thing I still can't explain is why Port A on the C1912 shows the root cost as being 0. It should be only 0 only if it sees itself as the root, but it doesn't because it shows the proper MAC address. Anyways, give that a shot and let's see where it goes.

With the capacity of newer Okay, how about lambda swtiching? :-) Photonic switching and lambda switching are _usually_ the same thing, although the purists insist that in photonic (usually), the information stays optical -- it's never converted to electrical signals inside the relay (note that I'm avoiding the loaded term router or switch). As far as I can tell in all proposals I've seen, these technologies are derivatives of MPLS, with additional information needed, say, to equate a wavelength to a MPLS label, or to use GSMP or LDP to control an optical cross-connect. The Great Lie of even "conventional" MPLS is that it somehow is independent of "routing." To be more specific, MPLS offers some alternatives in the "packet forwarding" part of "routing," but still depends on "path determination." I prefer to think of it as an "overdrive" to routing that only can work after routing protocols or static routing have defined the highway system. In the real world, if that is meaningful in so virtual a space, the actual sequence of events is along the lines: 1. L3 path determination, either dynamic or static, works out the connectivity. 2. Additional mechanisms, which may be no more than additional constraints on path determination, select Label Switched Paths (LSP). LSPs are associated with Forwarding Equivalence Classes (FEC), which are ways to leave your cloud (i.e., interface, output QoS, etc.) Think of these as hop-by-hop specifications of MPLS tunnels through an IP or other cloud that can map labels onto a cloud-specific forwarding lookup mechanism (label between L2/L3 headers, lambda, etc.) 3. Use a label distribution mechanism (LDP, RSVP-TE, CR-LDP) to distribute information to Label Switched Routers (LSR) on how to handle the next hop forwarding for a specific incoming label. Remember that the scope of a label is a single link. There is a relationship between a label and a FEC, but it's not a one to one relationship. Loosely, a FEC is operationally defined by sets of labels. LSRs are stupid; they don't know much about the traffic they carry. Think of ATM switches or LAN switches in a core with true routers at the edges. 4. Use Label Edge Routers (LER) at the ingress and egress to the cloud, to use rules to recognize the FEC to which traffic belongs, and tag the traffic with a label. In practical terms, the LER may have a rule that identifies traffic and puts it on a particular path (i.e., LSP with ingress label). LSRs forward the traffic given them by ingress LERs or other LSRs. Optical routing generally has the same logic, but the optical people tend to reinvent the wheel and the protocols. In my mind, a lambda can be a label, a VPI/VCI can be a label, and a L2/L3 shim can be a label. Sometimes the "difference" between optical and conventional routing comes from marketingdroids of the routing world, while other differences come from developers who began working with SONET, ATM, and other telco-oriented techniques and really don't understand Internet routing. Yes, there are different constraints to consider in an optical cloud than in a LAN cloud. But they are still constraints, and generic constraint-based routing algorithms can cope with them. Most Cisco (and indeed industry) discussions of MPLS focus, somewhat vaguely, on #4 of the steps below. But not to consider the role of routing mechanisms in LSP setup is to wave one's hands and say "here a miracle happens." _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: VLAN routing
I'm no routing/VLAN genius, but: If you have a simple environment, just use static routes as necessary. For example, a default route to the Internet as the only route and you will have no routes between VLANs. If you need one or two of them actually routed, just use static routes. If you have a more complex environment, I would suggest using a routing protocol (EIGRP, OSPF) and access lists to deny traffic between VLANs.

Re: alternative to Cisco routers
This is obviously an opinionated subject but, in mine, the reason Cisco equipment is relatively expensive is not necessarily because of it's performance. The strongest argument for Cisco kit in any bid I've seen is the level of support (i.e. the TAC). There are plently of other vendors who have equivalent products that are widely regarded as faster, more stable and cheaper than Cisco kit but when the chips (and your network) are down, try getting someone at Lucent/Juniper/Foundry to pick up your case within a few minutes and be on the phone to you and connected to your equipment to troubleshoot until that problem is fixed. In short, if you have Cisco kit, get a contract! It's worth every penny. Well, given that I do support for Juniper I'm afraid I have to differ with you. We take very good care of our customers. I'm sure we provide the same level of service, if not higher, than any other vender. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: bgp questions
Correct me if I'm wrong, but the only situation that bgp cares about IGP's synchronization is when bgp is explicitly configured to announce networks (i.e network x.x.x.x mask x.x.x.x) and it would have to check the igp to see if there is a valid route to that network. This can be overridden by 'no synchronization'. However, the default behavior is that bgp announces active (I'm not sure what activate means) routes (routes which are reachable via an IGP's routing table) to all configured bgp peers irrespective of whether they are an ibgp or ebgp peer. For this reason, I would select A. It's still very poorly worded, assuming 'activate' is not a typo. hope this helps On Wed, 14 Feb 2001, Rodgers Moore wrote: Yuck, really bad question.

Finally, after much procrastination all last year, I have finished this darn thing. I took the Switching test last summer, but then put the entire thing on hold because I was tired of all the studying. :-) But then an acquaintance of mine gave me an idea: just schedule the tests and that will force you study for them. He was right, that provided a great motivation. I schedule Remote Access five weeks ago, Routing two weeks ago, and then Support last night. I must say that the Support test is both easy and hard. It was fairly easy in some areas because I do a LOT of troubleshooting at work. however, some of the questions are *very* poorly written. I recall one question where you had to pick the "best" answer, but four of the five answer were correct and two of those were almost identical. Yikes. There were at least four or five questions where I made an educated guess because I couldn't figure out what they were really asking. And, as someone else mentioned before, the final grade is broken down into four categories and I don't remember getting a single question in two of those categories! I also have to sympathize with those of you who don't have anyone around who really cares that you pass your tests. None of my coworkers--including my boss--really care. My wife cares, but she doesn't understand any of it. So, I feel your pain. :-) Now, on to CCDP. I think I'll schedule that bugger in two or three weeks to get it out of the way.

The classic exchange point design features a carrier-grade physical facility, racks for the individual providers' routers, and a common layer 2 (sometimes layer 3) fabric to interconnect them. In the original NAPs, the providers often kept the BGP workload down by not having a direct BGP connection to every other provider there, but to one or more route servers -- BGP code running on UNIX boxes that do no forwarding, but build the maps of the exchange point. Today, there is less emphasis on the route servers for primary BGP, but there is still peering to them for statistics gathering. Some exchanges use a distributed switched fabric, so there is not one physical room. Instead, the participating providers are linked by ATM. It's something of an urban legend that the top-level providers do significant traffic exchange at the exchange points. At that level, they are far more likely to have private peerings over direct OC-3 or faster links. Exchange points, however, are useful for medium level providers in a given urban or geographic area. Indeed, there is an ever-growing trend to having metropolitan exchange points among cooperating ISPs in small cities. The traditional exchange is for ISPs only, but the line between hosting centers and exchanges is constantly getting more blurry. Large provider POPs are not necessarily smaller than exchanges, but simply have a different management and operational model. I don't want to be negative, but if someone hasn't been playing in the ISP area for a while, is familiar with the NANOG/RIPE materials, etc., they aren't remotely ready to design a carrier-grade POP or exchange by themselves.

Re: alternative to Cisco routers
You seem tense. If you search the web, you will find many companies already running linux or freebsd and have no problems with full BGP views. It really isn't too difficult maintaining T1s either. CCN? plus linux isn't mutually exclusive so I don't see the hubbub. The "correct" solution on a cisco list is what cisco says is the correct solution. That I'll grant you. We are merely extending our horizons and discussing possibilities. CCN?s on this list (myself included) need not feel threatened. And finally, I disagree with regard to cost. You can't get a 3640 with 128MB DRAM for under a thousand. Ok, *maybe* you can snag a used one cheap, perhaps cut a deal somewheres, but I did not intend this to be a MY OS is better than IOS war. Let's not go there. --- dre [EMAIL PROTECTED] wrote: I disagree, Linux is a bad choice! A Cisco 3640 router would cost about the same and I'd like to see you get a full BGP table with Linux for the same hardware cost. plus, linux doesn't have CEF or any of the standard stuff that comes with IOS (or JunOS for that matter). The SMB market does what they will, and who cares anyways? They have *no* market share, they aren't Internet players, they aren't market players, they are NOTHING. what they DON'T NEED is another strange weird solution that I would only put into a lab ; they need something standard, something that works, something that will scale, something that will perform up to their needs, and something that most $20/hour NT admins could configure. I am all for (ok not for Linux, but for FreeBSD maybe) an open source OS for research or inside a lab where others are familiar with it. But suggesting Linux routers for a SMB (or Enterprise, or Service Provider) in a production, real environment is insane. Don't get me wrong, I like Zebra, it's a good tool. But I would never run it if my mom and pop needed a "router" solution for their new cybercafe. The "correct" solution for SMB is a 1600 or 1700 series router. For what you say "most" SMB's a 1605-R (Single WAN, Dual Ethernet) and two Catalyst 1900 switches would be more than sufficient and would cost less in time/effort alone for the initial setup. Choose one person out the 165,000 CCNA certified people, and I'm sure at least 90% of them could configure this environment for 802.1Q, HSRP, remote management, NAT, Firewall (Secure Integrated Software built-in to the router), or VPN (IPSEC, L2TP, PPTP/MPPE). That's what they are trained to do. Show me a Linux certification or training program that discusses T1 cards or Zebra installation/configuration. And then give me some numbers...

RE: Networking White Papers (NAP and BGP)
The problem I am trying to solve... I am trying to develop a network access strategy based on the use of a NAP for my organization. I am tasked with preparing a whitepaper to address this. NAPs, or more correctly exchange points, are intended for itercarrier operation. Enterprises are usually not allowed to connect to them. So, if your organization is an enterprise, it's not a viable strategy. Large hosting centers may be the functional equivalent of exchanges, but they have an assortment of business models for who owns and operates the servers.

Dial Up networking books
Hi al I have been digging through the Cisco site for 2 weeks and as a final bootm line I decided that I need a good book to learn how to set up Cisco routers for different kind of dial-up dial-in configurations. Perhaps I missed something from the Cisco site but in my opinion it is impossible to have a big picture about dial-up networking with Cisco just browsing the web. I would be happy to find out about some useful links inside of this site because I would like to save my money. Coming back to the subject I would ask you to recommend me the best books for learning about that.

RE: alternative to Cisco routers
I like the Linux OS, but in my experience there are some problems with using it as a router for ISP connectivity. The most common situation is that I seen a bug with the PPP stack which causes the line to go into an up/down state. The problem is with LCP negotiation, for whatever reason, the Linux box sending its LCP negotiation and the router at the ISPs end is sending its LCP negotiation but neither one is reaching the open state. When you factor in the hardware costs of dedicating a computer for the task, and the hardware to link it to a T1 you are not far from the cost of a Cisco router. I would personally choose the Cisco router for this task.

The SMB market does what they will, and who cares anyways? They have *no* market share, they aren't Internet players, they aren't market players, they are NOTHING. what they DON'T NEED is another strange weird solution that I would only put into a lab ; they need something standard, something that works, something that will scale, something that will perform up to their needs, and something that most $20/hour NT admins could configure. I am all for (ok not for Linux, but for FreeBSD maybe) an open source OS for research or inside a lab where others are familiar with it. But suggesting Linux routers for a SMB (or Enterprise, or Service Provider) in a production, real environment is insane. Don't get me wrong, I like Zebra, it's a good tool. But I would never run it if my mom and pop needed a "router" solution for their new cybercafe. The "correct" solution for SMB is a 1600 or 1700 series router. For what you say "most" SMB's a 1605-R (Single WAN, Dual Ethernet) and two Catalyst 1900 switches would be more than sufficient and would cost less in time/effort alone for the initial setup. Choose one person out the 165,000 CCNA certified people, and I'm sure at least 90% of them could configure this environment for 802.1Q, HSRP, remote management, NAT, Firewall (Secure Integrated Software built-in to the router), or VPN (IPSEC, L2TP, PPTP/MPPE). That's what they are trained to do. Show me a Linux certification or training program that discusses T1 cards or Zebra installation/configuration. And then give me some numbers...

So my obligatory cisco alternative: www.zebra.org And, in a non-information technology related SMB, who installs and supports it? Good question. I think you are assuming larger sizes as "S" and "M" than does Cisco. When I did Cisco seminars for SMB resellers, one of the sales strawmen for "small" businesses was a dental office. More like 10 employees or so. (I did suggest that dentists would have special expertise in bridging, but, when my reference was understood, people threw pretzels at me). Perhaps a distinguishing feature of a "small" business is that they have NO professional network or system administrators. At best, admin is a collateral duty for an employee who may or may not have ANY training. My own dentist happens to be a technology enthusiast who likes working with computers, but, at some point, he realizes that time he spends doing administration is not time that can more profitably be used for billable patient care. My former internist was adept at getting his tie caught in the printer. I helped him get established with a Mac using the children's interface. My cardiologist, on the other hand, has a deep interest in medical information systems, and has a subspecialty in electrophysiology (and good hardware and algorithm background). While his group probably has 100 employees, they are extremely instrumentation-heavy and have a professional IT group. They spend lots of money on support -- think of their potential liability if they didn't, and a life-critical file got trashed. So while the cardiology group is small in numbers of employees, it's at least medium in terms of sophistication. They are starting to get into things like remote imaging with ATM links and the like, using technologies we tend to think of as large business. I think under 1,000 employees is reasonable for a mid-sized company. Less than 400 is a rough estimate for a small company. These companies tend to already have people taking care of their NT/Novell servers. Typically they already have file servers, print servers, and sometimes a router or two. But what if it's something like a home improvement center? Quite likely to use a turnkey inventory control system, but, depending on how the initial system was sold, may or may not have internal (or contract) support staff. Even large businesses may very consciously want to focus on "core competences". I can think of several computer and network manufacturers who outsource such things as help desks, server admin, payroll, etc., for various financial reasons. Maybe an Exchange server, Groupwise, or perhaps they've thrown together a home grown solution with qmail plus mysql plus cucipop. Throw in some switches to hook it all together. Maybe no 802.1d or VLANs in the mix, but still, a sustainable technology environment. But the average SMB that's not in the IT business probably hasn't thrown together a home grown solution. They don't have the staff to know where to start. Even more dangerous is that they may have people who know the components, but don't know how to make them foolproof--or even worse, geniusproof. And routing isn't too difficult, really. Especially in small environments: Anyone reasonably intelligent who knows TCP/IP intimately, can manage routing, or a firewall for that matter. I might have agreed until you said firewall. I'm far more likely to recommend outsourcing security administration than network administration. It's not that a firewall is necessarily hard to configure, but it is hard to know what should go into the configuration. Developing the security policy needs lots of experience. At the day-to-day level, anyone who expects to run a reasonably secure firewall needs to stay on top of the firewall, CERT, etc., mailing lists. That takes time, time which a consultant can amortize over multiple customers. Routing is reasonably straightforward until you start getting into high-availability, business critical functions, especially involving the Internet or extranets. Or learn how to. Anyone reasonably adept with a CLI can learn IOS. (IOS, in fact, is a far more primitive environment than the Unix shell.) And outside computer science programs, very few people are literate with UNIX shells--statistically speaking of the overall corporate environment. I've worked for small companies. The limited resources require sysadmins who can wear several hats and learn quickly. It's just the nature of the beast, nasty, brutish, but for expediency's sake,

Re: alternative to Cisco routers
This is obviously an opinionated subject but, in mine, the reason Cisco equipment is relatively expensive is not necessarily because of it's performance. The strongest argument for Cisco kit in any bid I've seen is the level of support (i.e. the TAC). There are plently of other vendors who have equivalent products that are widely regarded as faster, more stable and cheaper than Cisco kit but when the chips (and your network) are down, try getting someone at Lucent/Juniper/Foundry to pick up your case within a few minutes and be on the phone to you and connected to your equipment to troubleshoot until that problem is fixed. In short, if you have Cisco kit, get a contract! It's worth every penny. Well, given that I do support for Juniper I'm afraid I have to differ with you. We take very good care of our customers. I'm sure we provide the same level of service, if not higher, than any other vender. I've always been amused at the Cisco theory (on which they seem to be relaxing) that a CCIE, in particular, needs to be expert in everything, yet the TAC staff are divided into six or so specialty areas. At least when you call Juniper, there's no danger about your being shunted to an SNA or desktop expert in lieu of someone who deals with carrier-class routing. Again, one of the counterarguments to canonizing a company because it offers end to end solutions. SMB and carrier support requirements are very different. Even large enterprises often have different needs. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Converting from IGRP to EIGRP
First, please do not put everything in the same AS. This is a very bad thing, and I really wish Cisco would kill the feature. (I think it was placed in there for marketing) There are two standard ways to do this. The first is border - you simply redistribute and filter with distribute lists. The redistribution point can be moved as you convert, or more added (although you should only have two routers invloved if possible). The other is overlay. Both IGRP and EIGRP run on all routers in the network, but EIGRP's AD is weighted higher. Then you pull IGRP off. Any router that is not running IGRP will advertise the routes via EIGRP, and the only real trick is memory and making sure that you work from the outside in on the IGRP removal. --- "Roberts, Timothy" [EMAIL PROTECTED] wrote: I posted this a few weeks ago and only got a few responses so I thought that I would try again.

HI LEIGH ANNE and everyone, The problem was fixed by allowing VLANs out of the trunk on port f0/21. (See below).

I would like now to document the rules used to solve this problem: Leigh Anne, please correct me if I am wrong! 1) The spanning protocol includes trunk ports in its calculation. 2) If a trunk is not allowed to trunk any VLAN, the port is considered inactive 3) Since an inactive port does not forward traffic it does not create a loop 4) A port that does not create a loop will not be put in blocking mode (which explains my earlier problem) So LEIGH ANNE, when are you going to claim your CCIE?

RE: Modem to Console Port
John brought one thing to light that I forgot to mention earlier. By connecting a modem to the router, you are opening a security hole into your network. Make sure to set a timeout on the console port so that when a user hangs up, the console session will timeout and another user can't come in behind you and grab your console session. You may also want to have somebody at a remote branch physically unplug the phone cable from your router after you have completed any configuration changes. Better yet, control access to your routers with Cisco Secure ACS. You can then set privilege levels on a user by user basis as well as logging access to your networking infrastructure.

Terminal Server for beginners
Group I have been fighting with the performance of my terminal server for a few weeks now. It works, and I have been using it, but like I said I have been fighting with it. It seems to send characters to other ports when I haven't initiated a connection to that port. The way I can tell this is when I get onto that port it is responding to characters entered even though I haven't entered anything. This is quite peculiar. I have looked at many books to see if I am doing something wrong and the only indication was in Bruce Caslow's book saying if your terminal server incorrectly shows active connections on lines that don't have any connections established the command "modem host" on the line config will fix this. Well this didn't fix mine for s*#@. I finally figured out the way to fix mine was to add "modem inout" boom it works like a charm. I am running 12.0.8 on this 2511.

There are some situations when running two paralel PVCs is necessary in FR clouds experiencing congestions. Sometimes FR network are implemented in such way that network device at cloud edge allow customers to transmit frames exceeding CIR without setting DE bit at entry point. When customer want to be sure that priority data frames within CIR bandwidth would not be dropped, he must mark other nonpriority frames with DE bits. Assuming that other customers transmit all frames within cir and above without setting de bits, theirs frames are preferred at congestion points. The workaround for this inequal treatment is to run two pvc's - one subscribed with cir and one without cir, putting all nonpriority data into second pvc not marking it with de bits.

RIF length Field Question
Hello all, I'm a little confused over "length" bits in the RIF. The Token Ring White Paper (Lou Rossi), states that "bits 12 through 8 describe the total length represented in bytes." It goes on to say that a value of "a" indicates there are 3 bridges, an "8" indicates there are 2 bridges, and a "6" indicates there is one (1) bridge. My question is this: Does the above parameters take int0 account the very last bridge i.e., since all RIFs end in a bridge of "0," is this last bridge (0) included in the count of the length bits? Example: Packet type = specific route Direction Frame size = 512 Host1--ring--bridge--ring--bridge--ring--Host2 Would this be a "0830...xxx0" or a "0A30...xxx0" The reason that I ask, is because on several CCIE practice test, as well as the actual written exam, the answers do not seem to regard this fine point. thanks _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

So I thought: "well, I can change the priority of the interfaces and reload the switch and that should do the trick". Well it did not (See below). I can only think of two things: A. I have not understood proprely the use of a port priority and I am changing the wrong parameter B. I have changed the right parameter but there is something else that I am missing in the configuration. Port FastEthernet 0/26 of VLAN1 is Forwarding Port path cost 10, Port priority 100-- I changed this from 128 to 100 Designated root has priority 32768, address 0050.3EF0.3580 Designated bridge has priority 32768, address 0050.3EF0.3580 Designated port is 22, path cost 0 Timers: message age 20, forward delay 15, hold 1 --More-- Port FastEthernet 0/27 of VLAN1 is Blocking Port path cost 10, Port priority 0 --I changed this from 128 to 0 Designated root has priority 32768, address 0050.3EF0.3580 Designated bridge has priority 32768, address 0050.3EF0.3580 Designated port is 23, path cost 0 Timers: message age 20, forward delay 15, hold 1 Pierre-Alex As several people have found out recently, I **love** understanding all the nuances of why technology works the way it does. When things go wrong, it's so much easier to identify a problem when you can compare what SHOULD be happening to what IS occurring. Took me a while to pick through everything, but my spanning tree troubleshooting skill-set increased significantly as a result of this exercise!

HI LEIGH ANNE and everyone, The problem was fixed by allowing VLANs out of the trunk on port f0/21. (See below). I don't have an amber light on the blocked port but since the show span indicates that the port is blocked I can live with that. (Maybe TAC should be the next step!) I would like now to document the rules used to solve this problem: Leigh Anne, please correct me if I am wrong! 1) The spanning protocol includes trunk ports in its calculation. 2) If a trunk is not allowed to trunk any VLAN, the port is considered inactive 3) Since an inactive port does not forward traffic it does not create a loop 4) A port that does not create a loop will not be put in blocking mode (which explains my earlier problem) So LEIGH ANNE, when are you going to claim your CCIE? (My apology if you already have it!)

Re: Terminal Server for beginners
Under line 1 8, issuing a 'no exec' command should also do the trick. ak Brian Lodwick wrote: Group I have been fighting with the performance of my terminal server for a few weeks now. It works, and I have been using it, but like I said I have been fighting with it. It seems to send characters to other ports when I haven't initiated a connection to that port. The way I can tell this is when I get onto that port it is responding to characters entered even though I haven't entered anything. This is quite peculiar. I have looked at many books to see if I am doing something wrong and the only indication was in Bruce Caslow's book saying if your terminal server incorrectly shows active connections on lines that don't have any connections established the command "modem host" on the line config will fix this. Well this didn't fix mine for s*#@. I finally figured out the way to fix mine was to add "modem inout" boom it works like a charm. I am running 12.0.8 on this 2511.

SMB and opportunities (was Alternative to Cisco Routers)
Anthony Kim continued, Intersting thread. I didn't know cisco defined a small business so strictly. Is that an exam question? :) Historically, commercial data networking started with mainframes interconnected with leased lines. These machines were either in large enterprises or in academic/research institutions. SNA, for example, gave extensive operational control, and needed a considerable staff to support it. I've seen a market research report that said: in 1982, 86% of networking customers could build and support their own networks in 1996, 14% of customers could do so. It's not necessarily that enterprises are more or less clueful -- it's that the enterprises that get into communications are much smaller or more poorly budgeted. The distinction has been made that networking began with the Fortune 500, but now has spread to the Fortune 5,000,000. As business dependence on networking grows, the smaller companies have the alternatives: Without internal or external network support staff, wait for a major failure (hard downtime, or inability to service their customers) and go into bankruptcy. Hire from a scarce pool of qualified (certified?) people and watch their margins go down, if they don't have enough networking activity to keep these (expensive) people busy. Go into bankruptcy. Buy networking products that are as turnkey as possible. Buy support, which may or may not stay within their margins. Of course the bottom line is, you make technology recommendations on what the business can handle, what they require, and what they can afford. At some intersection of this triad, an answer may surface. I am fortunate in that my experience with networking people have all been with knowledgable and clever folks. It has long been a valid assumption that no one ever went broke by underestimating the intelligence or taste of the public. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: alternative to Cisco routers
Well of course a 4700 (or equivalent) will handle more traffic than a 2501!!!

Witches or not, think about this. Cisco is end of lifing the 2500 series this year.
