Guys , thanks for all your help so far.. let me elaborate a bit more ..this is our setup 1 x 3640 router to outside world 2x serial (to diff sites) 1 x FE goes to 1 x 2948-LG3 FE Goes to 1 x 6509 Via Fibre another 6509 is acting as HSRP backup. what is happening is that we are getting the bridge port message on the switch..but we are also (on the MFSC and 3640) getting this EIGRP message %DUAL-5-NBRCHANGE :ip-eigrp (AS no) neighbor xx.xx.xx.xx is up :new adjacency then %DUAL-5-NBRCHANGE :ip-eigrp (AS no) neighbor xx.xx.xx.xx is down : holding time expired 30 secs later .. have swapped cable ,switchport, FE card,IOS 12.0.15 still no good..

Re: CertificationZone White Paper EIGRP ?
Hi, I am pasting the feedback which I got it from one of the author for the same query -- My Question -- Check the formula for the composite metric - If k5 is 0, then the metric becomes 0 as per your formula. Instead of * k5, should it be + k5 ? Feed back --- Nope--it should be multiplied. EIGRP doesn't follow your normal everyday rules of algebra! :-) If k5 is 0, then this term of the formula (the multiply by k5) is ignored. It should probably be written: * max(k5, 1) or something like that. :-) Russ Regards / Thangavel HCL Technologies Ltd.

Phil, Doyle (Routing TCP/IP, volume 1) has a slightly more useful explanation. In the IGRP chapter (he doesn't dicuss EIGRP metrics much as he just refers back to the IGRP formula which is the same), he explains "If k5 is set to 0, the [k5/(reliability + k4)] term is not used". It implies that there are essentially two different formulae: [k1*BW + (k2 * BW)/(256-load) + k3 * delay] * [k5/(reliability + k4)] if k5 <> 0, and [k1*BW + (k2 * BW)/(256-load) + k3 * delay] if k5 = 0.

Thanks for that link Glen, It looks now like its me against the world. In the UK I would call K5 the nominator of this part of the equation and "reliability + k4" would be the denominator. If the nominator = 0 then the expression k5/(rel + k4) will be 0. As a result when multiplying by anything on the left will result in 0.

Re: telnetting?
Windows 2000 has telnet server support. Great for quickly checking status on things, stopping/starting services. Of course, since it's telnet, security it out the door unless you're on a totally switched network. I like it because I can telnet in behind a PIX, and then telnet back into the firewall's inside interface. Of course, I could do this with a router or manageable switch on the inside, but that's not always the case. Just some thoughts, especially from a security point of view as well.

RE: CiscoWorks2000
Rik, CiscoWorks 2000 is slow. We used CiscoWorks RWAN on a Compaq DL380 (733Mhz processor, RAID5, 768 MB RAM) for a client. We did NOT use MS SQL, just used the Microsoft jet database for indexing. (1) Heed the software versions in the documentation. (2) Configure an administration console on a workstation (it's in the docs). This will significantly offload some processing to the client -- client-server model, eh? (3) I'd recommend 1 Gig of RAM. (4) Maybe use SQL vs. jet database for indexing. (5) Download the patches and updates from CCO. You did sell them Smartnet, right? (6) Use RME.

Re: subnetting and tcp/ip and Private addressing Help!
IMHO, one should never be shortsighted and think that they'll never be connected to the internet. Of course, even if you use RFC1918 addresses and you end up merging with another company using RFC1918 address, you'll probably end up renumbering. But at least start with something that you can reasonably assume you won't have to change. Mainly, start with .50.x or higher for your subnets if you think you'll ever merge with another company. USE DHCP! If you need statics, get the MAC address and assign the static address in the DHCP server. That way, you have a decent change of not having to renumber, or when you do, it'll be easier. Why am I harping on this? Tonight's project: re-number 4 sites, all numbered with 192.168.1.0/24 (4 different newspapers bought by one company). At least I get to do it all remote from the router side of things. All I have to do is remote in, set the DHCP & WINS from disabled to automatic (I've already configured them all), change the IP address (good thing NT/2k can handle this on the fly and just let me reconnect, then reboot for DHCP/WINS service to notice the change). Then all the support grunts get to run around to 1000 PCs between all these sites and change them to DHCP. I'm sitting in my PJs on my couch, by the way, so I'm not too grumpy compared to the rest of them. Of course, being a newspaper, we can't get started until late tonight. *sigh* -- Jason Roysdon, CCNP/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Cisco resources: http://r2cisco.artoo.net/ <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Well, if the network isn't connected to the Internet, and isn't going to > be, then you can use whatever addresses you like.

RE: ************** Which is more common - OSPF or EIGRP? ******** ***********
Heres my 2 cents... OSPF is a open-standard used by many people making routing products. EIGRP is Cisco propiertary (no RFC/no open standard) and Cisco-gear only runs EIGRP that I know of. There may be a small # of vendors who licensed the protocol from Cisco for their use. Back in the early 90s, when networking was starting out and before people had more choices, people stuck with one company for the most part. It was popular for people to use cisco routers and Synoptics hubs. In this time period, before people focused on standards, etc EIGRP was used more if they had cisco. Why? I think because it was a improvement over RIP and wasn't as complex to get running as OSPF for the small amount of gear that did OSPF at the time. Users were just starting to understand networking, etc. As things developed over the years and more players came into play interoperability became more important, standards were more important to use and follow, software became more stable, easier to configure/use, hardware became cheaper, etc. My first real job in the early 90s was in a Cisco EIGRP and Synoptics environment. AGS+ in the core. Over the years we replaced the dumb hubs (synoptics) with early cisco and Synoptics/Wellfleet/Bay switches and upgraded routers but stuck with EIGRP because it was in place already. Today, I work in a multi-vendor TAC environment and deal with interoperability issues regularly and use standard protocols whenever possible. I've seen alot of funky stuff between different boxes. Even though there are standards, everyone implements them in a slightly different manner so there may be things you need to tweak to get it optimized.

Re: OSPF Process ID
That won't be a problem at all since the "process ID" means different things for EIGRP and for OSPF. For EIGRP it servers as a routing domain, for instance a router with an EIGRP with a process number of #100 will only communicate with other routers with the same process id. With OSPF however the process ID refers to the routing process on the router and it has no significance beyond that particular router so you could have one router with OSPF process ID 1 and one with OSPF process ID 2 that would communicate just fine. Having EIGRP and OSPF have the same process ID won't cause any problems at all. Your updating problem must be stemming from some other issue, you could always post your configs if you wanted some help.

RE: wrong subnet
One place I worked placed all their routers at the dot 100 address. Printers were all dot 1 through 10. All other clients were DHCP. Kind of a pain to set up DHCP scopes initially, I suppose. Their security folks did this deliberately, the idea being that since everyone numbers their routers as either dot 1 or dot 254, that's where hackers ( internal, in this case, because it was al private addressing ) would be looking. It would be easier for the snoop software to discover someone trying to telnet to a couple hundred addresses than it would be to discover someone attempting to break into just a couple of addresses. Well, that's what they said, anyway.

Altiga Question
Hi Group, I'm facing problems setting up a VPN connection with Altiga and Windows 2000 CA server. (Using L2TP) Can anyone advise/suggest the correct procedure of implementing the solutions ? Componets of of my Network are :- 1. A Cisco Router 3640 2. A Pix Firewall 515 3. Altiga 3000 VPN Concentrator 4. Switch 2948G- L3 5. Windows 2000 Advance Server. I run the NAT on PIX and currently have only ports 80,443,22 &1352 open. I followed the procedures : "Installing Digital Certificates on Cisco VPN 3000 Concentrator" , "Configuring the Cisco VPN 3000 Concentrator for Microsoft Windows 2000 Support" & "Using a Microsoft Windows 2000 Client to Connect to the Cisco VPN 3000 Concentrator" These all references are download from the offical Cisco Web Site. After doing these a protocol error "Error 789 : The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer." Also from the design perspective advise me where to keep the Certificate Server, like should it be in the DMZ or running in the internal network (does it really matter ?) On the Alitga, in the ESP-L2TP-TRANSPORT template, what are the settings that should be there ? The error may be related to the fact, that we accidently deleted the transport template and re-added it . Also advice the on how to setup the Windows 2000 Certificate Server ? Regards Manoj Ghorpade.

Re: wrong subnet
Absolutely nothing wrong with putting a gateway at the high-end of things. It's all up to feasibility. Most networks I come across are 192.168.1.0/24 networks with the lower addresses already in use. The next most logical address to use to me is starting from the last and working backwards. It's a very common practice in originally non-networked LANs. Often I'll also have sites that do have one router to their remote sites at something such as 192.186.1.1/24, and again the rest of the lower addresses are in use by server, printers, hosts, etc. Again, the best addresses to start using IMHO is the top end working down (instead of right in the middle where some semi-technical user is likely to step over it). The main thing to me is standardizing things, so if I can place all my routers at .254 instead of .3 on one subnet, .5 on another, .8 on a third, I'd rather have them all .254. Just my two cents. Hmm, speaking of which, my router at home is 192.168.45.254. Of course, my old WinGate gateway was at 192.168.45.1, and we had hosts starting at .2, so again, I went to .254 for my new router. -- Jason Roysdon, CCNP/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Cisco resources: http://r2cisco.artoo.net/ "Craig Columbus" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hmm...depends on your meaning of correct.

RE: subnetting and tcp/ip and Private addressing Help!
Well, if the network isn't connected to the Internet, and isn't going to be, then you can use whatever addresses you like. Not recommended to use any old class A (just because requirements always change - you may have to merge with another network, you may need Internet connectivity in the future etc), but it will work. You can use NAT (Network Address Translation) or PAT (Port Address Translation) to translate your 'inside' network addresses (i.e. anything you choose) to legal assigned Internet addresses. This can be done either statically or dynamically. Not all protocols work with NAT; for example if the IP address is contained in the data portion of the application packet, NAT needs to be aware of that and needs to change it there as well (which may mean re-calculating checksums etc - messy). It is generally recommended (actually, I think it is universally recommended) that if you have a choice, use RFC1918 Private addresses if you're not using 'real' (i.e. allocated to you) addresses. These are address blocks set aside and not allocated to anybody. 10.0.0.0/8 is the class A address defined as a 'private' address block. Why might you use some other class A? Well, we use multiple unassigned class As in our internal network. It makes it easier to have an addressing scheme that uses the octet boundaries - you don't need to be able to think in binary to be able to work out what office a particular address refers to. On its own, that isn't a very good reason - but our network addressing scheme was implemented before RFC1918 came out, and it's a large, geographically distributed network with several hundred remote sites (very remote, some of them). The effort and pain that would be involved with re-addressing is, so far, greater than the effort and pain in working around the problems caused by using 'illegal' addresses. Sooner or later we're probably going to have to readdress, but personally I'm hoping somebody comes up with some other solution ;-) JMcL -- Forwarded by Jenny Mcleod/NSO/CSDA on 16/01/2001 12:37 pm --- Jennifer Cribbs <[EMAIL PROTECTED]>@groupstudy.com on 16/01/2001 10:21:57 am Please respond to Jennifer Cribbs <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] To: "John Pusledzki" <[EMAIL PROTECTED]> cc: [EMAIL PROTECTED] Subject: RE: subnetting and tcp/ip and Private addressing Help! There is such a thing as private addressing where you can have any address you want, but you usually have something set up at the router that dynamically assigns you an address space when you leave your network, such as out in the internet world. That way you remain legal... And the addressing within your network is your own business then. I do not know how this actually works, but I do know this is an option.

RE: subnetting and tcp/ip my correction...and comment
Thank you Craig for correcting me. I glad I have it basically correct, since all I have is your basic ccna. I have no more knowledge than that. As far as all your info you enclosed...who is it for? Me or Charles, who wanted to know why there are zeros at the end of an network address?? If we go this way and go into that much detail with him, don't you think you should explain first of all to charles what a classful address is and then explain how that is related to the trailing zeros in answering his questions regarding basic network addresses and why they have zeros at the end?? If you also want to confuse his "basic" question and tell him about a loopback address, before you can explain what a loopback address is, you have to get him to understand the concepts of a network address or no point has been made!! And nothing is understood. Information when you start out has to build or you never get the concept and without the conceptual understanding, you fail the test. And yes craig, I know that routers base their information on binary numbers and not numerical numbers, but charles did not ask the question in regards to binary numbers. He used his examples from a numerical point of view. And also, but maybe you don't remember, when you start out, you don't really cover multicast and experimental addresses, because it's is overwhelming at times to just get the concept of a class b Jen By the way...explain to me what a vlsm network is...from a basic standpoint.. >= Original Message From Craig Columbus <[EMAIL PROTECTED]> = >Jennifer has it basically correct.

I have a network, ip address 130.5.0.0 (why is it 0.0)? Do all network #s end in 0? And for Class B to have the network address, must it be x.x.0.0? Cant I have something like 172.5.5.0?

OSPF Process ID
Hi, group: Will this a potential problem if I have both EIGRP and OSPF running in the same router with the same process ID, for example, ID #100. The reason I am asking is because I have the exact situation on one of my router, it seems like the router could not participate in the OSPF updating domain. The only difference I can see from other OSPF routers is this router is also running EIGRP with the same process ID. I am not doing any redistribution here between EIGRP and OSPF.

RE: subnetting and tcp/ip and Private addressing Help!
There is such a thing as private addressing where you can have any address you want, but you usually have something set up at the router that dynamically assigns you an address space when you leave your network, such as out in the internet world. That way you remain legal... And the addressing within your network is your own business then. I do not know how this actually works, but I do know this is an option. I think I read something about NAT providing this service. The group would know about this. I do not. Chuck is a good one to ask on this issue... The question is how come someone can have a class a address that internic did not assign. Anybody?? Jen Have a Good Day!!

Re: What is a Cisco 3801?
Well, I wouldn't say it's entirely useless as a lab machine, I guess it depends on what level of labs you plan on doing. I have one and it was great for my CCNA, along with a 2501 (a must have). The 3801 has a slow Ethernet connection, two synchronous serial lines, and a T1 controller line, as well as (I believe) a couple POTS lines, not sure though. The last IOS version that was released for the thing was 11.3(18) or something, and so you've got some limitations there. As I find myself preparing for the BSCN exam I'm finding more and more limitations. It's a little irregular in the way it interacts with EIGRP and other routing protocols. Anyway, if you can get one at a cheap price it wouldn't be too bad for a beginning lab. - Original Message - From: "Nick Brooks" <[EMAIL PROTECTED]> Newsgroups: groupstudy.cisco To: <[EMAIL PROTECTED]> Sent: Monday, January 15, 2001 4:00 PM Subject: Re: What is a Cisco 3801? > the 3801 was the first conception of the 3810. avoid this at any cost. > > Albert Lu wrote: > > > Hi all, > > > > I've been doing some research on the 3801, I don't think Cisco even knows > > it has it. > > > > I just wanted to know what sort of router it is, and what it is capable of. > > Is it worth getting for a home lab? > > > > Regards, > > > > Albert > > > > _ > > 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] > > _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

vlan and dhcp-------help
at our site we provide ip adresses to workstations via dhcp. We ahve around 10 Vlans . I have the vtp domain on a CAT 6509. RUNNING IOS 12.0(7)XE. on its msfc's (2). The Core switch trunks to various Cat 4006's. Users on a certain vlan 106 coamplained that they could not get network connectivity as they were not agetting an IP adress. I connected my laptop to the switch on wich the ports were assigned for valn 106 and was unable to get an IP address. Hower when I configured my laptop with a static IP I was connected to the network. I configured a port for vlan 106 on another cat4006 and got the same result. I have * Portfast enabled, * port channel mode disabled * and trunking for ports disabled. * Also I did not see any mismatches. of ports. *also ther ip-helper address is setup on my MSFC's Cisco believes that there is a bug in ios ver 12.0(7)xe and told me to download the new config 12.1(5) that has the fix---as explained below Release Notes Forwarding of bootp/dhcp address request UDP packets fail because of encapsulation failure.

RE: subnetting and tcp/ip
Hmm, you would be better of getting a book which explains the basics of IP addressing, but let me see if I can explain it a little for you. I do not know how much you know about the classes, but 130.5.0.0 is a class B because the two first bit's in the first octet starts with 10. - 130 is 1001 in binary. So in a class B network you now know that it starts with 10 and the network uses 2 octets, so you have the following networks available as class B : 1000. thru 1011. or 128.0.x.x thru 191.255.x.x, so where the 5 comes from in 130.5.0.0 is just whatever class B address is available in that scope - this could have been 156.17.0.0 instead. Lets say that you get the 130.5.0.0 network from your isp, you would then have 65534 (2^16 minus 2) available addresses for devices on your network. That's a lot, so if you have a number of departments in your company you wish to isolate on the network, you can split the network up in subnets, based on how many subnets you want, and how many hosts you need on the biggest subnet. For example, if you choose to use the third octet for subnetting, you can have 256 networks with 254 (256-2) hosts on each. That way 130.5.11.120 could be a workstation on network 130.5.11.0 and 130.5.28.39 could be a printer on network 130.5.28.0. The way you would specify that subnet scenario would be by using the subnet mask 255.255.255.0. The 130.5.x.x now changes to 130.5.0.x (or 130.5.1.x, 130.5.2.x, etc.) If you are still confused, I would recommend that you read a book about it, because you really need to know the basics and up to be comfortable messing with it. A book like Todd Lammle's CCNA study guide for exam 640-507 has a pretty good explanation about all this, and if you choose to read the entire book and follow all the examples and practise it on a couple of Cisco routers, you would find yourself a lot smarter, and you could even be smart enough to try the CCNA exam and get certified. Anyway, there's a LOT of books out there with good TCP/IP explanations in them, so what I would do if I was you, would be to follow these steps: 1) Click here http://www.groupstudy.com/bookstore/index.html 2) Look at the books and click on any of them to jump to Amazon.com (this is important so they can see that you came from groupstudy) 3) Search for books about tcp/ip or ccna 4) Read the reviews - I would not choose any books with less than 4 stars 5) When you have found a book you would like to buy, copy the ISBN number 6) Go to http://www.booksamillion.com and choose search for ISBN and paste the number 7) Most of the times, you can find the same book there cheaper than Amazon.com 8) Buy the book and sign up for a years membership for only $5.- which you will save right away 9) When you receive the book - read it.

Re: subnetting and tcp/ip
Ok, here we go... We will start with basics...all network addresses end in 0. Whether they have 1,2,3 zero's depends on whether it is a class A, a class B, or a class C network address... class A 0-127, which is x.0.0.0 , as long as the x, is between 0-127, it is a class A "network address". class B 127-191, which is x.x.0.0, as long as the "first x" is between 127-191, it is a class B "network address." class C 192-223, which is x.x.x.0, as long as the "first x" is between 192-223, it is a class C "network address." You don't need to worry about class D or E. They are for experimental purposes and they have the first number set in access of 223. Network addresses are assigned by internic to companies and whether the companies get a class A, B, or C depends on the size of the network and availability . Gov agencies usually have A's. Very large corps. usually have a B, and everything else has a C. When companies get their network addresses, they can break them down into private addressing for organization within their companies, and for ease of management. And that's where the other numbers come from that you were referring to. BUT, the address class is determined by the first number, or the first octette. If your number is in binary format, you add it up to figure out what the class is. Do you know how to do that? If not e-mail me. Your address of 172.5.5.0, is a class B with a network address of 172.5.0.0.The 5 in the third octette is from within the company and is the address of one of their subnets and is used by their router to direct traffic to that particular subnet within their company. Routers "out there" in the WAN side of the world only use the network addresses for routing. And you have to know what class it is, in order to determine how many octettes are in the "network address" . An address of 192.5.4.3 has a network address of 192.5.4.0, because it is a class C, and therefore is of the form x.x.x.0 The 4 addresses you have: 130.5.32.0 130.5.64.0 130.5.160.0 130.5.224.0 All these addresses come from the same network, because their network address is 130.5.0.0. It is a class B of the form x.x.0.0 The other numbers direct the traffic to different, specific parts of that network within the private company that has the network number 130.5.0.0. Those other numbers are derived from by a process known as subnetting and that's a different lesson. Good Luck!

RE: CertificationZone White Paper EIGRP ?
Phil, Doyle (Routing TCP/IP, volume 1) has a slightly more useful explanation. In the IGRP chapter (he doesn't dicuss EIGRP metrics much as he just refers back to the IGRP formula which is the same), he explains "If k5 is set to 0, the [k5/(reliability + k4)] term is not used". It implies that there are essentially two different formulae: [k1*BW + (k2 * BW)/(256-load) + k3 * delay] * [k5/(reliability + k4)] if k5 <> 0, and [k1*BW + (k2 * BW)/(256-load) + k3 * delay] if k5 = 0.

Re: CCNA-WAN Study Material
- The ICWS sylvan test for CCNA-WAN follows the style of questions that you would see at the Chapter Review points. When you say "from the courseware" are you referring to the actual classware, or the CCNA-WAN book that can be bought. The book that can be bought has several chapters that seem to have been lifted from the courseware. - My advice: Know what module fits into which product, and what modules they can occupy. The test is also structured kind of neat, in the way that they seem to cover one product at a time. i.e, IGX then BGX, then BPX.

RE: subnetting and tcp/ip
1. 0.0 is the host portion, reserved for your host IDs, the network portion is 130.5, given the default subnet mask of 255.255.0.0. Not all network numbers end is 0s. For instance, if your subnet mask is 255.255.255.252 (classic for a point-to-point network), your network number might be 192.1.1.4. You can have a network number of 172.5.5.0. What really dictates where the network ends, and the host portion begins, is the subnet mask. In order to fully understand IP addressing, take the IP address and covert it to binary. Take your example: 130.5.0.0, in binary is 1010.0101.. (the bit values are 128 64 32 16 8 4 2 1). The default subnet mask for a class B address is .... The ones (on bits) in a subnet mask designate "network" values, while the zeros (off bits) designate values that can be used for host numbers. Remember to follow the simple rule that the host portion cannot be all 1s (broadcast), or all zeros (this network only). You really can't learn IP addressing quickly in an email, but be positive, and you will get it! 2. You can't tell if two IPs are on the same network without taking the subnet mask into consideration. You refer to a class B (subnet mask 255.255.0.0). This being the case, all 4 numbers given refer to the same network. In a default class B network, the first two octets designate the network number, leaving the last two octets for hosts. In your example, the 130.5.0.0 is the network number, and the third and fourth octet are for hosts. HTH, Evan P.S.

RE: subnetting and tcp/ip
Beside the IP address; Another piece of info you need is the subnet mask. Together, they determine the subnet group.

Re: Saving config file
Jason, The Catalyst series of switches does not have a startup versus running system config.

Re: Saving config file
Think of the 5500 as only having ONE config file. (as opposed to the running / startup in a router). Be careful with the changes you make since a reboot cannot save you from an error or a test.

RE: Frame Relay...Inverse-Arp..?
If the router at the other end is non-Cisco then you'll have to specify IETF encap for the Frame encapsulation. The frame relay encapsulation type should be independent of the LMI type. If the telco is using non cisco switches then you just set your lmi type to whatever they are using. The DLCI being passed is a function of LMI it has nothing to do with Cisco or any cisco tampering with their LMI code it should work with cisco, Ansi, and Q933a LMI types. This should all work in any live environment unless there is a non-standard configuration ie the telco is not advertising LMI at all so you have to put "no keep" under the interface.

My best guess is that the LMI is passing the important information across the point-to-point links. As for doing this with the Telco, I am not sure.

RE: Frame Relay...Inverse-Arp..?
The only time this doesn't work is if you have no keep on the fram int or you are doing frame relay back to back between 2 routers without a switch which involves use of the "no keep" statement. Try a "sho fram pvc" or "debug fram LMI" in either e live environment or test environment where there is a switch and the end routers should always receive their DLCI's from the telco. When trouble shooting FR if you are troubleshooting someone else's network this is the greatest aid. If the customer's network is supposed to be up, but is not passing layer three many times debug fram lmi or sho fram pvc will tell you if the customer has configured the wrong DLCI's because you will see what they have config'ed and then you will see what the switch is advertising to their router on the main interface as learned dynamically. This is a basic function of FR.

Re: Cisco to 3Com Dot1Q trunks and VLANs
Michale, I have dot1q trunks running across Cisco MDF switches and Nortel IDF switches. We found that Cisco and Nortel run two different versions of Spanning Tree, both of which are 802.1q compliant. The difference between the two is that Cisco's portfast feature, and Nortel's faststart feature are different, where portfast has a default forward delay of 15 seconds, and faststart doesn't implement the forward delay feature. This resulted in a huge amount of TCN's (topology change notifications), particularly in the morning, when all end users are booting up their pc's and changing to 'forwarding' mode in spanning tree. As a result, we opened a ticket with Nortel, and they agreed to add forward delay to their switching code to correct this problem. I would check the STP documentation on both vendors, and determine if all the default values are the same, what the default root bridge priority number is with both vendors, who you have configured as your root bridge, etc. I would even plug a sniffer in and capture some traffic... Draw out a spanning tree diagram, and document your root bridge, and the subsequent switches in the spanning tree. Those are just some suggestions... Hope you find some results.

Telnet has two sides: a user side and a host side. It was implemented before the client/server terminology was used, but that's basically what it is.
