CIT Down 1 to go [7:8311]
Hi Group, It was not easy, but it all ended well yesterday by my passing the CIT exam with 885 scores. What surprised me most was the grouping of the exam. I was scored 75% in HDLC and I can't remember answering any question on that. I wrote Switching 2.0 last week Tuesday, With my passing Support 2.0 yesterday, it is now left with Remote Access which must be hacked down early next week. After that the week following will definitely see CID down as well. Am greatful to all in this group your immense support has been of great value to me. Have a nice day. Regards. Oletu H. G.

Re: LLC Type 2 [7:8262]
>Fresh from reading for my Support exam from Cisco Press CIT SDLC is >the granddaddy of them all. created in the mid-1970's to transport >SNA. ISO modified SDLC to create HDLC.

Other than for Cisco tests, I'd be hesitant to take Cisco Press as gospel. That time sequence doesn't sound right -- indeed, the organizations are wrong. I do have some personal experience with these. Ideally, one would go back to the original standards documents, or at least some textbooks from the early 70's. Cypser would be one endorsed by IBM, or I have the original IBM Systems Journal issue on SNA somewhere here. An author such as Priscilla could probably check with some of the original authors (at least the ones still around) -- I ran into Hal Folts a couple of months ago. I first installed SNA in 1974, which included SDLC. ITU-T didn't exist yet. CCITT was the ancestor, and its first X.25 standards were in the 1972 books (I forget the color now--probably yellow or orange). That used LAP. The first commercial X.25 networks deployed in 1972, the first a banking network in Spain and then Telenet a few months afterward. I attended Federal Telecommunications Standards Committee meetings in 1976-1980 or so, where we worked on the ADCCP extensions to HDLC. No one particularly assumed an SDLC heritage, and indeed very carefully used different terminology and bit encodings. LAP-B was in the X.25 1976 standards. IEEE originally was going to accept Ethernet, which didn't have an LLC equivalent. IBM's proposal to standardize token ring originally suggested that everything have the equivalent of LLC2, making everything reliable like SDLC. The compromise was to create connectionless LLC1 and connection-oriented LLC2. LLC 3 was developed by the MAP project, primarily General Motors, and I don't think it ever became a full IEEE specification. It certainly isn't in my copy of 802.2. > >NetBEUI and SNA both need the reliability of LLC Type 2.

LLC2 [7:8315]
Michael I am a bit confused.If you have SNA still on the network (which most big Corporates do) would you not be using Token Ring? Can you run SNA over Ethernet using LLC2? why only LLC2 & not LLC1 or EV2 ?? Below you stated that LLC2 is diminishing because of the reliability of higher protocols such as TCP, however as I understand SNA does not use TCP and therefor you will always need LLC2 if you are running SNA.?? Can you please clarify or point me in the direction of a good book. As I understand Netbios & SNA can be encapsulated in TCP ,& therefor use its connection orientated services & run over ev2 or 802.3SNAP. If you were implementing SNA & NETBIOS straight onto the wire would you then have to use LLC2 ( DO THESE PROTOCOLS HAVE TO RUN ON A CONNECTION ORIETATED TRANSPORT) rgds.

Re: bgp [7:8282]
D'wayne, BGP rides over TCP/IP. Therefore you need a functional TCP/IP network in order to use BGP. If your routing is done with static routes, BGP will work fine over statics.

RE: back to back 2500's acting as a firewall [7:8251]
an interesting idea, i have to say. but, i think you don't have to worry about the nat. configure it on the ethernet port that goes into the cable modem, and simply allow your network behind for nat. the question is if you have a static ip address assigned from your isp (which is unusual) or is it going to be negotiated? If it is negotiated, then you need 12.1.t version to be able to configure ip address dhcp under the ethernet port (cisco still doesn't have ip add negotiated command for lan interfaces). int e0 ip add dhcp ip nat out int s0 ip nat ins ip add 1.1.1.1 f.f.f.0 access-list 1 permit any ip nat ins source list 1 int e0 overload This should work.

Payload length in IPv6 datagram [7:8336]
Hi all, I would appreciate your insight in the following question I have received from my student. My answer follows but I am not sure I have not missed some important piece here. Q: Why was the meaning of the packet length parameter changed from total length to payload length when moving from IPv4 to IPv6? It looks to me like deliberately created fuel for confusion. My Answer: IPv4 header might vary between 20 to 60 octets, and in first 20 octets there are 11 fields which need to be looked at and possibly processed by routers along the path traversing internet. This unnecessary complexity leads to inefficient router's performance. By employing a simple header of fixed length with 8 mandatory fields, IPv6 routers enhance their performance. As we could see, many fields were either removed or embedded in the extension headers in IPv6. As the IPv6 header has a fixed length of 40 octets, the Header length field could be eliminated. Payload length is the length of the remainder of the IPv6 packet following the header, in octets (extension headers plus the transport-level PDU). IPv6 as opposed to IPv4 does not perform any checksum in the base header, again to allow for faster processing at intermediate nodes (routers). The routers only check what is needed to check: in case of IPv6 they are interested that the complete header is there (they know what length to expect - fixed 40 octets) and that the rest of the datagram is complete in terms of advertized length. Therefore instead of identifying the whole datagram length from which they would substract the 40 octets, they know immediately what the payload length is. This seems quite sensible; perhaps we could attribute this sort of discrepancy between versions rather to the IPv4 way of specifying the whole datagram length instead of the data (payload) length. IPv6 moved away from that for practical reasons - routers' efficiency.

Hi all, Trivial yet fundamental question.

Re: Catalyst Gurus [7:8177]
As others have said, check to see if portfast is enabled. But also check to see if trunk autonegotiation is enabled and if Etherchannel/Port Aggregation Protocol is enabled. These two will typically consume about 18 seconds to negotiate and figure out that your Fluke (or other device) isn't trunking and isn't channelling. Commands: show trunk [m/n](look at mode, usually defaults to auto, you may want it off) show port channel m/n (look at mode, usually defaults to auto silent, you may want it off) set trunk m/n off (turns trunking off completely on this port, no negotiation) set port channel m/n mode off (turns channelling off completely on this port, no negotiation) Ethan ""Larry Ogun-Banjo"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > We have just installed some new catalyst switches 650x and 69xx.

Re: Radware's linkproof and Fatpipe [7:8085]
If you have two ISPs then you'll have two sets of public addresses assigned to you already. Their solution is to internally map one address from each pool to each inside resource making them reachable through each ISP. Then you do DNS round robin to get "load balancing". I just don't like that solution because it's not as transparent to the end user, but it does have some benefits: No ASN needed, BGP is unnecessary, and it conserves addresses since you won't need an entire /24. Unless, of course, you really do need a /24, but you probably don't from the sounds of it. Regards, John >>> "Kenneth" 6/12/01 8:12:21 PM >>> Cool. I just thought it was too good to be true.

FYI: CCIE Lab Scheduling [7:8342]
Greetings, I just scheduled my CCIE R&S Lab and found it rather interesting that the first available dates in RTP are either in two weeks, 6/26/01, or the middle of February 2002. San Jose was not much better. Either today, 6/13/01, or the middle of the January 2002. I chose the February date because I needed the time to make travel arrangements and to do a little more studying. I was hoping to take the Lab some time this fall, but I guess that is not going to happen. I can't believe there is a six to eight month wait to take the Lab. I passed the written Exam in late March 2001. If I would have waited much longer to schedule the Lab I may have had to take the Written Exam again. I think it is time that Cisco looks at adding some additional testing facilities or additional seats the existing sites. Any ideas why there is a 6 to 8 month wait for Lab Exams??? Are there that many people taking the Lab Exam??? Andrew E.

Re: ARP and TCP/IP layering [7:8335]
This topic has come up a few times in the past and I don't think we ever came to a common agreement. Several people made good arguments on both sides. I don't recall the specific argument, but I believe someone even made a convincing argument that it was an application layer function. Perhaps someone here remembers that thread and could refresh our memories. When most people think of host-to-host communications they think of one layer on one device speaking to the corresponding layer of another device. In this case of ARP I personally feel that we have the network layer of one device speaking to the datalink layer of another. Even that point is a little shaky because at the destination the packet must reach the network layer to be recognized, but the information desired from the end station is layer two, not layer three. I would also suggest that we determine the layer at which a function resides by looking at the layer that originated the request for information. In this case, it's the desire of the network layer in one device to speak to the network layer of another device that initiates this entire process. An ARP is generated at the request of the network layer. This ARP seeks out the destination device, gathers the necessary information, and delivers that information to the network layer of the originating device. Because of those two arguments I'd say that the ARP function overlaps both the network and datalink layer. It is a datalink frame generated at the request of the network layer, and it just doesn't fit perfectly into either layer. Then again, I may be wrong. :-) Regards, John >>> "Dr Rita Puzmanova" 6/13/01 7:58:53 AM >>> Hi all, Trivial yet fundamental question.

Stripping to a minimum of OSI speak, what we think of the network layer actually has three sublayers, one of which arguably extends into the data link layer or at least overlaps it. The Subnetwork Independent Convergence Layer is the truly link-independent part such as IP or CLNP. The Subnetwork Access Protocol is the interface to intelligent layer 2 protocols that have payload identification -- X.25, ATM, LLC, etc. The Subnetwork Dependent Convergence Facility maps between the Subnetwork Independent and Subnetwork Access parts. ARP goes here. Going a step farther, it's also worth considering the functional as well as layering models of B-ISDN/ATM, which identify the U(ser), C(ontrol)/signaling and M(anagement) planes at each layer. ARP is a C plane protocol between the end host and the ingress relay, much as is Q.931 and Q.2931. IP routing protocols, PNNI and SS7 are relay-to-relay M plane protocols.

question on configuring a isdn dialer rotary group [7:8360]
Hi Gang, I have been presented with a project to configure a remote isdn connection. We will be using ISDN to connect a remote site into our central site. I have two separate ISDN lines at each end which I want to be able to combine (multilink) for a total bandwidth of 256. I believe this can be done using a rotary group but I have never configured this before. I am used to configuring legacy ddr. So I have been looking on the Cisco site and in documentation cd and there are a couple of questions I have. First, here is some basic information on my two routers. The central site is composed of a Cisco 3640 with a bri card and internal NT1's. The remote site will have a Cisco 2611 with a bri card and internal NT1's. I will be connecting two bri's on each end. The remote end will be calling in to the central site but no one on the central site will be calling out. I have found the following information on the Cisco site regarding configuring legacy ddr: http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_ c/dcbri.htm#21895 I have a couple of immediate questions. One is, do I need to identify the SPID's and if so, where? Normally I would define these under the bri interface. By the way, my switch type is basic-ni on both ends. Also, under the interface dialer would I need to define a dialer map statement for each separate channel? i.e. dialer map ip 1.2.3.4 name centralsite broadcast 111222 dialer map ip 1.2.3.4 name centralsite broadcast 111222 dialer map ip 1.2.3.4 name centralsite broadcast 111222 dialer map ip 1.2.3.4 name centralsite broadcast 111222 Here is what I have as far as a config so far on my remote router: interface BRI1/0 description **to 84.252 bri 0/0** no ip address encapsulation ppp dialer rotary-group 1 dialer-group 1 isdn switch-type basic-ni isdn spid1 2814650193000 4650193 isdn spid2 2814650194000 4650194 ppp authentication chap pap callin ppp multilink ! interface BRI1/1 description **to 84.252 bri 0/1** no ip address encapsulation ppp dialer rotary-group 1 dialer-group 1 isdn switch-type basic-ni isdn spid1 2812974325000 2974325 isdn spid2 2812974326000 2974326 ppp authentication chap pap callin ppp multilink ! interface BRI1/2 no ip address shutdown isdn switch-type basic-ni isdn T203 1 ! interface BRI1/3 no ip address shutdown isdn switch-type basic-ni isdn T203 1 --More-- interface Dialer1 ip address 152.x.x.241 255.255.255.252 encapsulation ppp dialer in-band dialer idle-timeout 1200 dialer map ip 152.x.x.242 name centralsite broadcast 7133860442 dialer map ip 152.x.x.242 name centralsite broadcast 7133860443 dialer-group 1 ppp authentication chap ppp multilink !

What is the Lab 'like'? [7:8366]
All, I am looking forward to a run at my CCIE next year and I am trying to visualize what the Lab test will be 'like'. I have read Cisco's material and searched around a bit, but that info falls short of what I am looking for here. I understand the lab consist of essentially two parts; build out and troubleshooting. How are the Problems/requirements presented? For example, are you given very high level requirements such as "build a scalable network" and you make all the design decisions, or are you likely to get more specific requirements such as; "plan and addressing scheme to conserve IP space and router resources", or even more specific like: "select and OSPF network type to use in your network"? In the troubleshooting section, do they insert faults that you have to discover, or do they provide you with at least some clue of which high level functionality may or may not be working? Real world troubleshooting is usually in response to observed problem, or issue. Is it fair game to have something tweaked in the configs that is not expressed in any level of functionality, or lack there-of, on the test pod? Are the problems presented in writing, orally by the proctor, or both? Do you deliver to the proctor diagrams, and notes, or just the configs and cableing on the routers. Are you required to orally defend your design? I am not interested in info that violates the agreement with Cisco, just any input that can help me visualize what it will be like. Thanks!

SNMP Counter [7:8369]
I am working on script to keep track of line errors and total packet throughput using SNMP. All I need to get is the input, output errors and total packets in and out. The cisco documentation isn't clear enough. http://www.cisco.com/warp/public/477/SNMP/5.html Does anyone know what variables I should query using snmpget for total packets? What is the difference between "interfaces.ifTable.ifEntry.ifOutUcastPkts" and "interfaces.ifTable.ifEntry.ifOutNUcastPkts" ? I am assuming that total packets out is the sum of the 2.

RE: question on configuring a isdn dialer rotary group [7:8360]
the biggest question here if you two lines are configured as a hunt group,
which would mean only one phone number for all four b channels. this is
usually the case, so just by having the ppp multilink, you shold be able to
do this. there is one more command that you must not forget:
dialer load-threshold 15 either ("15 either" can be changed, of course)
under your dialer interface.
Your config looks good.

Re: span port [7:8310]
No you will not catch all the frame if they exceed 10mb. The cat may not even allow it. I am not sure. but if the switch does allow it, and the data amount exceeds 10mb, then it can not possibly mirror from 100mb to 10mb which your laptop is set to. -Patrick >>> "Bob S" 06/13/01 01:16PM >>> Yes, you will be able to mirror the traffic from the source you've specified to the destination port.

Re: What is the Lab 'like'? [7:8366]
Go to www.cciebootcamp.com . They have pretty good write up. I know of 2 guys that just took itand I dont know but they both said they were going to smoke ityet they both never got invited back on the second day. Perhaps they undersetimated the amount of material and the little hidden mines along the way that this exam is famous for. The only thing I disagree with is the statement that one of the guys made. He did not really care that he failed but that he had "seen it" and now knew what to do. I think its this kind of attitude which will cause him more problems. If he tends to assume that the exam he took is the only blue print he will set himself up again to fail. Anyway, these guys work with me and said the exam was truly a monster.

Frame Relay Network [7:8381]
I want some help regarding connecting cisco routers across a frame relay based TDMA ( Time Division Multiple Access ) Network. In TDMA network, main site (hub) is connected to different remote site having remote unit (each site has differet DLCI). At main site there are two different path, one for transmission (Tx) and other for Receive (Rx). So at main site a Frame Relay switch is used to switch data from TX and RX path to DTE device ( e.g Cisco router). Currently a main cisco router is connected to switch port and differnt remote router connected to remote terminal (star topology). The configuration used is at main site subinterfaces are reated for each remote site and set specific interface dlci for each subinterface). Configuration at main router interface s0 encapsulation frame-relay no keep-alive ( as TDMA has lmi disabled) no ip address interface s 0.1 ip addr 192.168.21.1 255.255.255.0 frame-relay interface-dlci 17 interface s 0.2 ip addr 192.168.22.1 255.255.255.0 frame-relay interface-dlci 18 and so on as depend on number of remote sites. Cofiguration at remote sites interface s 0 encapsulation frame-relay no keep-alive no ip address interface s0.1 ip addr 192.168.21.2 255.255.255.0 frame-relay interface-dlci 17 and same at all remote site routers. How can I replace frame relay switch by using two serial port of Cisco router and route data from both TX and Rx path to LAN ethernet port? I want to eliminate switch and want to take same work with cisco router. My understanding is that cisco router works as frame relay switch by receiving data of a specific dlci from a serial port and swich to different serial port with a differnt or same dlci. Can Cisco router transmit and receive data of same dlci at different serial ports and route these data to LAN ethernet interface? -- ___ Get your free email from http://mymail.iname.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=8381&t=8381 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

CCIE lab prep. Is there a syllabus? [7:8385]
I just passed the CCIE R&S written, and prepared for this exam using the road map posted on the Cisco web site. Is there a similar document for the lab? I asked one of the CCIE's here at work, and he told me to study "Everything". Needless to say, this was not helpful. Is there something that will place some specific boundaries on what you need to study? I have seen info that EXCLUDES certain topics (X.25, Decnet, Vines...), but nothing that INCLUDES anything. thanks Chris Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=8385&t=8385 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: selling routers [7:8376]
Consider that there is a "retail" and a "wholesale" price for used gear. Most of us who buy on eBay or from resellers pay retail. When you sell you get wholesale. May I suggest that you look on eBay under completed auctions for a ballpark figure for your equipment. Then put it up for sale to individuals at 75-90% of used retail. All would benefit.

There are definitely errors in Cisco material. In the past, certain training developers simply didn't want to change them "because it would confuse people." There are other reasons, significantly including that the average course or test developer is not a subject matter expert. Indeed, I know of firms to which Cisco outsourced course development which actively did not want subject matter experts writing courses, but instructional methodology people -- even if the subject matter expert was an experienced instructor and course developer. I literally got a downcheck in my performance review at Geotrain because I insisted on being a technical authority rather than managing external experts. If I were hiring someone for a network design role, much less product development, I'd be far less impressed by someone that had nine specialized CCIE certifications, than someone who had published in independent technical forums, could document real network design experience, etc. Nortel's certified architect program, among other things, requires candidates to document five networks they have designed, with their assumptions and design choices. The US military has had a lot of success with intensive training -- train like you fight, fight like you train. But there is a huge difference in correspondence to reality of something like the CCIE lab, and running tank battalions around the National Training Center at Fort Irwin. The CCIE lab has an artificially small number of routers; the NTC consciously outnumbers the US troops with people with home field advantage--but regards the experience first as learning and second as testing. > > >>From: "Priscilla Oppenheimer" >>Reply-To: "Priscilla Oppenheimer" >>To: [EMAIL PROTECTED] >>Subject: LLC Type 2 [7:8262] >>Date: Tue, 12 Jun 2001 19:15:33 -0400 >> >>I found myself writing this paragraph for a new writing project: >> >>When NetBEUI and SNA are used on Ethernet networks, they take advantage of >>the reliability of LLC Type 2.

There are other reasons, significantly including that the average course or test developer is not a subject matter expert.

I despised this aspect of training at Cisco. It's the number one reason I'm not there any more. Cisco thought a course developer could write on any topic as long as there were SMEs available. That's why we have so many dribble bits in Cisco courses.

Frame Relay Encapsulation and LMI [7:8406]
In response to the current frame relay switching thread I setup a little experiment at home last night. I configured frame relay switching between a hub and two spoke routers, all three using Cisco encapsulation and LMI. Show frame pvc indicated that all circuits were active. Then on one of the spokes I changed the encapsulation to IETF and then reset the interface. To my surprise the circuit came back active and stayed that way. I thought for certain that it would go inactive but it did not. I then changed the LMI type on the same router to ANSI and the circuit died a quick death. So, it seems that the encapsulation type did not effect the circuit status. I guess to understand this more I need to find the frame formats for Cisco and ANSI frame relay. Perhaps they are slightly interoperable but one has different features than the other. Regardless, I didn't expect the circuit to stay up, but it did. If I later discover why this occurred I will post to the list.

Complete Redundancy [7:8409]
I have a client who needs "absolute" complete redundancy for their Internet service. I assume they should be using 2 separate links with different ISPs. What I don't have hands-on experience with is the physical connections and HSRP. Will I connect both routers to the local switch and then configure HSRP between them? Any help would be greatly appreciated.
