Re: what is loopback interface for ? [7:9493]
Hi.. Sorry, I need a few more questions to verify whether my understanding on loopback is correct or not? Pls answer it. 1) If I have two router A (loopback=192.168.0.1/32) and B (loopback192.168.0.2/32), Router A's S1 int 100.100.100.1/24 is connected to Router B's S1 100.100.100.2/24. There are no more other connection. If S1 of B is down. Can I still telnet from A to B using B's loopback address. 2) If Router A and B have another connection. Router A's S2 int 100.200.100.1/24 is connected to Router B's S2 100.200.100.2/24. If S1 of B is down. Can I still telnet from A to B using B's loopback address? 3) If Router A doesn't have loopback int configured. Can we still telnet from A to B? 4) Whether the loopback IP address need to be in order or same network? Let say Router A's loopback is 192.168.0.1/32 and Router B's loopback is 20.20.20.1/8. Can we still telnet from A to B? 5) If I configured A's loopback IP to be 192.168.0.1/24, can we still configured B's loopback to be 192.168.0.2/24?

Re: ATM configuration !!! [7:9962]
It seems your ATM connection is mapped to two different locations. Then you should create two point-to-point subinterfaces and don't use the mapping. A point-to-point interface is just for one connection only.

OT: Beware of Shady Equipment Sales [7:10078]
Most of you are probably aware of this already, but just as a reminder... Be extremely CAREFUL of outside scam artists that try to solicit and try to sell you Cisco equipment (or anything for that matter) by contacting you directly. I'm constantly bidding/selling on ebay in search of good deals and occasionally I get emailed outside of auctions if I am interested in purchasing the same equipment directly. This one person emailed me the following offer and he seemed pretty innocent and professional. He offered to sell me 2514's at $450 (very good price) and 2513's at $550 (way too reasonable), all loaded with 16/16 memory. I agreed to his offer and informed him that I could deliver cash if he was in the local area, or pay via COD or escrow. He came back claiming that he supposedly "lost tons of money and equipment" through COD and didn't want to pay costs for escrow (although I offered to split the costs with him). He basically said that he could only accept payment of wire transfer and that I could "trust" him to ship out on the same day on receipt of payment. I asked why he didn't post those items on ebay and he says that he'd rather do business with people directly. (go figure) I ended up politely declining his offer. He was never rude or discourteous to me though. So in a nutshell, be really careful of these types of people. Who knows, he could've been legit and honestly been trying to sell decent equipment and fairly low prices. Maybe he doesn't want to list his name and maybe he doesn't have his own business email address, but I'm 99% sure that this guy is out to make a quick scam on some sucker who will fall for his trick.

A better question is why the Groupstudy mail server does NOT record the IP address of the submitter of the message in the headers. Sendmail records this information by default unless you configure it not to do so. For that matter, why the groupstudy mail server does not have RFC compliant DNS records configured for their mail server - the forward and reverse dns do not match, causing TCP wrappers to record it as a security risk in your syslogs.

Re: Yikes....New product alert.... [7:10031]
Sure! Here's the public link: http://www.cisco.com/warp/public/cc/pd/rt/7400rt/ In a nutshell, it's a one rack unit router with two gigabit ethernet ports that also shares port adapters with the 7500 series routers. And, it can process 300kpps! That's just really spiffy.

Re: Theoretical vs. Actual Bandwidth - Refining the Question [7:10070]
About 18 months ago I asked a similar question, and received some very useful answers (or at least some useful discussion points) Responses then were, reasonably enough, that it varies wildly depending on the application, and that ideally you can do some analysis of the application. I threw up a notional figure of 5% for overhead for 'back of the envelope' calculations when you can't do any application analysis - some people though it was a bit low, some a bit high. For most purposes you're probably better using the 25% figure to make sure you're covered :-) If you want to search the groupstudy archives for the earlier thread, search on overhead;rough;measures in December 1999. JMcL -- Forwarded by Jenny Mcleod/NSO/CSDA on 27/06/2001 12:00 pm --- "Priscilla Oppenheimer" @groupstudy.com on 27/06/2001 07:55:50 am Please respond to "Priscilla Oppenheimer" Sent by: [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: Re: Theoretical vs. Actual Bandwidth - Refining the Question [7:10017] It's not as simple as it sounds, of course. ;-) A good start might be Cisco's Technology Overview here: http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/index.htm That document shows typical header lengths for Frame Relay, ATM, ISDN, PPP, HSSI, SMDS, SDLC, etc. Search the group study list for more on Cisco's HDLC header. The HDLC frame format has been published here a few times. The exact header lengths will depend on which variety of each protocol you're using. For example, ATM headers are longer with AAL3/4 than with AAL5?? (I'm not an ATM expert.) Frame Relay fragmentation headers are different than vanilla Frame Relay headers. You probably would want to account for other protocol info that is overhead: call setup, signalling, SLARPs, LMIs, etc. Then, lest we forget, the equation depends on how much payload the upper layers put into frames. HTTP typically uses 400-600 byte packets, as do many database applications. Voice uses 64-byte packets. Terminal applications (like Telnet) use 64-byte packets. (A user types the letter A. The letter A is echoed back, and the echo is acknowledged.) Large frames (1000-1500 bytes) are typical of file transfer activities, such as saving files, executing applications, loading word processing documents, using FTP, etc.. E-mail is pretty impossible to predict. Attachments would use large frames. Message are hopefully small, but sometimes they are like this message. ;-) Then how about upper-layer overhead such as TCP acknowledgements? The number of ACKS depends on window size. Any retransmissions? And what else uses bandwidth? Routing protocols? Network management? Tunneling? RSRB? So Maybe just believe the SE who told you to assume about 25% is overhead, unless you want to do a real traffic analysis? ;-) 25% seems believable to me. How expensive is bandwidth? A real analysis might be worth the work... Sorry for all the hand-waving, but I'm in a bit of a rush. Hopefully you see the issues though.

Re: Cisco 2502 - home lab [7:10061]
Personally, I like the 2502. Better to have a 2513/2514, with two LAN
interfaces, but the 2502's tend to be a bit cheaper than the typical Ebay
2501. One the majority of the 2500 routers, the serial interfaces are the
same, so you'll be okay there. I have a nice variety of 2500 boxen, and
tend to use the 2502's more than the 2501's, anyway, out of a sick
determination to get my head wrapped around TR. (Plus I get to tease the
Ethernet-only engineers at work, playing with their collision farms).
To really do anything with the TokenRing interface, you'll also need a
token ring hub, or a token ring MAU (IBM 8228's are cheap, and simple), as
well as another token ring device. When you configure the rouer's TR
interface, it won't fully come up, unless there's another TR device on the
hub/MAU. You might look to buy a TR NIC for your PC, to meet this
requirement, until you buy another TR-capable router. Several ebay
sellers have piles of older TR cards, NICs, and MAUs for pretty cheap. I
picked up a box full of TR toys last year, it came with a half-dozen NICs,
two 8228 MAUs, and a nice assortment of cables. Note that the 8228 is a
passive electro-mechanical device, and sometimes the relays inside get
stuck (if it's been dropped). You can use a TR reset tool ("phaser") to
reset the relays, but they aren't as easy to find as they used to be. If
you know any dinosaur network engineers, they probably have a spare in
their desk (I bribed a mainframe hippie for mine).
I would also suggest that you purchase a basic 1-year SmartNet contract on
the router, as well (around $275, IIRC). That gets you access to various
IOS software to run (but not the license to run them -- as long as it's
not for a production network, you'll probably be okay), as well as access
to the Cisco TAC helpdesk to answer questions (no matter how basic) on
setting up your router. It'll also provide for replacement hardware if
the router breaks, but that's less likely than needing help at 2AM, after
you've had a few beers and the damn LSAs won't show up in the OSPF table.
(Those TAC engineers in OZ have put up with me more than once, late at
night, failing to grasp simple stuff).
The only other thing I'd mention is that you'll be needing more than one
or two routers for CCIE prep, but start small, until you get the basics
understood. I think that one router is enough to tackle the CCNA
knowledge, and two is probably enough for CCNP topics. Three would be
nice, for playing with Frame-Relay emulation, and multi-area OSPF, but see
what your needs are, before you buy more than that. As you learn more,
you might decide you need a rackfull of boxes, but by then you'll
(hopefully) know enough about the product lines and their capabilities,
and can make better decisions about what to buy to meet your needs -- like
a few 7513s, a pair of LS1010's, maybe a nice Cat8500 ... :)

IP/MAC force binding [7:10060]
Does somebody know if it is possible to force an IP/MAC address binding on a Cisco router or switch? For example, IP packets with source address 192.168.56.1 can only come from a NIC with MAC address 01-02-03-04-05-06. Any packets with IP source address 192.168.56.1 and another source MAC address are not allowed by the router or the switch. If the answer is yes, which IOS feature should I use ?

Re: Theoretical vs. Actual Bandwidth - Refining the Question [7:10058]
"What is the sound, Grasshopper, of one hand clapping?" said the traditional master. And the techie student answered, "Start an audio recorder. Clap one hand. Play back the recording. That is the sound of one hand clapping." If there are some critical applications such as ERP, presumably there are at least LAN-based testbeds for them. Why not take some actual measurements, especially that show the interactions of multiple clients and servers? I'd try to do this as much as possible on 10 Mbps switched Ethernet, to be at least somewhat comparable to WAN links. I suspect you are looking more for utilization than absolute lengths, but you should be able to do some extrapolation. As a general observation in queueing theory, latency starts going up, with reliable transfer protocols, much above 50% utilization. At a given MTU level, I suspect the data link header lengths will not be a significant difference. Signaling? FR and ATM have them, but LMI traffic isn't all that frequent. Will you be running CDP? Signaling involved in setting up VCs only occur at setup (surprise!), and whether they are Q.2931 or PPP, will be lost in the noise if the circuit stays up for any appreciable time.

6509 MSFC problem [7:10057]
Hi, I have two 6509s (A&B) with two MSFC on each running mslp and hsrp. Did anyone heard about there's problem running mslp and hsrp with four MSFC failover? the problem is that there are only two MSFC failover but don't apply to all four, if you have experience on this problem, please help! The other problem I've had is that, assuming there are only two MSFC running active & passive mode, it shows status is 'others' instead of 'ok', anyone knows what's happening? My guess is on the active node(Switch A), hsrp already failover to the passive(Switch B) one, so layer 3 is fuctioning. However, the Switch A still passing traffic to the associated MSFC, so it causes traffic jam in Switch A, but in fact the traffic should go through Switch B instead. Please suggest...

RE: Yikes....New product alert.... [7:10031]
Basically its a high end (comparable to 7200 VXR) in a 1U chassis and appears aimed at the service provider market. Heres what Cisco have to say: "Cisco Systems has developed a flexible and robust network services gateway to meet these needs: the Cisco 7401 ASR-GW. The Cisco 7401 ASR-GW combines high performance and availability with a rich feature set and ease of management. The Cisco 7401 ASR-GW extends the Cisco product portfolio by providing industry-leading performance and rich IP services in a one-rack unit (1RU) form factor. The Cisco 7401 ASR-GW is the result of combining the small form factor of Cisco routers such as the Cisco 2600 and 3620 Series with the performance and services of the Cisco 7200 VXR Series. The Cisco Parallel Express Forwarding (PXF) technology embedded in the Cisco 7401 ASR-GW is the key for delivering the line-rate performance and features required in a state-of-the-art network services gateway."

Re: Is a CDP frame a broadcast, multicast or unicast? [7:10024]
Debug is kind of limited. You could get a free analyzer!? I encourage it. There's a list of analyzers here: http://wwwhost.ots.utexas.edu/ethernet/enet-analyzers.html By the way, I did answer your question the first time. I'm not sure that you saw that. On Ethernet, CDP sends to the Cisco multicast address 01:00:0C:CC:CC:CC. I hope that didn't ruin the surprise. ;-) Priscilla At 05:26 PM 6/26/01, [EMAIL PROTECTED] wrote: >I turned all debugging for CDP on and I am no seeing much?

Re: Is a CDP frame a broadcast, multicast or unicast? [7:10024]
Try debug ? You'll see that there's a debug cdp. I don't know how useful it is though. There's a bunch of debug commands. Debug packet is generally used when you don't see anything with the more specific commands because the router can't figure out what the frame is. Also, start here for Cisco documentation: http://www.cisco.com/univercd/home/home.htm From there go to Cisco IOS Software Configuration. Go to the IOS version you are using. Go to Supporting Documents, which includes a Debug Command Reference! Good luck. Please send messages to the group, not to me. Thanks.

Re: ip default-network 0.0.0.0? [7:10027]
Depending on what routing protocol you're using, the default-network forces the router to advertise itself as the default gateway of the receiving router... In case of EIGRP, if you don't explicitly create an ip route 0.0.0.0 0.0.0.0 x.x.x.x, the remote router will not know how to route packets destined for unknown subnets. If you create the ip default-network y.y.y.y on the headend, the headend router will advertise itself as the default gateway for the route. wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > What will this do? > ip default-network 0.0.0.0 > > Is this preferred over routing protocols?

Re: Administrative Distance [7:9921]
Thomas, Surejust use the distance parameter at the end of the ip route command: ip route (network prefix)(mask)(next hop router) 1-255. "1" being the highest possible distance and "255" causing the router to not ever use this route. This is called a floating static route.

My problem is that I want to get my computer science degree and I dont think I can get both and work at the same time. I am about 2 and a half years from graduating. I also work 40 hours a week as a computer tech for an elementary school. I have hands on experience with cisco only in a lab enviroment, not in a production network. I feel confident that I want to keep learning networking, but at the same time I feel I am missing something by not having a degree and not having a broader understanding of computer systems. The longer I work and put off school I know it will be harder for myself to get the degree. Now I am deciding to go to school full time (after I save up some money) and get the degree done. I guess the only reason I feel hesitant about doing this is because I am getting closer to getting the CCIE and that has been my focus for the last year and a half. But I have been thinking about it and I think having the degree behind me will help in the long run if I want to go into management or if I decide to maybe get into network programming (which I know nothing about but am kinda curious to learn). Part of me wants to get into the field now, but the logical part of me is telling myself to wait and get the degree. I dont want to get a cisco related job while going to school because that will postpone myself getting the degree or take away from my job because I am focusing on school.

If it contains no destination, then why are you wondering if it is destined to a broadcast, multicast, or unicast address? On LANs, it does contain a source (the router or switch that is sending the info) and a destination, the Cisco multicast address 01:00:0C:CC:CC:CC. Perhaps the statement meant that on a point-to-point WAN link it doesn't include a source and destination. That could be true.

RE: Access list problem [7:9939]
Hi, This to me would seem to be a fairly standard sort of access-list where you are enforcing all to use internal proxies permit tcp any host 203.111.42.204 eq www permit tcp any host 203.111.42.215 eq www These can then get the required data from the web. I assume these are running proxy services. If you point your browser directly ouit to the web you will get nothing.

Re: Passed BSCN - 873 [7:9976]
Imran, I used the Cisco Press CCNP library for routing and switching exams and I've found that even the bits I wasn't sure on were in the book, I just hadn't studied it quite enough. I've bought a couple of the Boson tests and they've been very useful, and pretty reasonable at 20 quid each (ish). Ole Drews Jenson's site was pretty useful too, particularly for the switching.

Re: Catalyst 6500 Confusion [7:9983]
I would say that the overall architecture of the Catalyst 5x00/6x00 series is definitely overcomplicated. I personally think that because it's so overcomplicated, it has to have less performance and reliability, etc than other products that do Layer 3 switching. This is not verified completely, but if you look at just the basic specifications for what a packet does in hardware for Catalyst 6500 vs. other vendors (i.e. Foundry) you will begin to understand that the Cisco approach is probably not all it's cracked up to be. However, Cisco definitely has some distinct advantages in many environments, and with the SUP2 MSFC2 + dual DFC and PXF enabled linecards they claim 15 million access-lists at line rate. We'll see how they perform in real networks in this upcoming year. I don't think Cisco is making things more complicated; I am beginning to think that they don't understand it either. And that is scary. -dre ""John Neiberger"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Believe me, it all looks funny to me, too!I think this is Cisco's > attempt to make things more complicated than they need to be. > > Perhaps deciphering acronyms will be on the revised CCIE exam.

Basically, yes. Unless you exceed the 128k max flows or hit the hashing collision. And other situations might exist as well. On CCO you could read: http://www.cisco.com/univercd/cc/td/doc/product/lan/cat5000/rel_5_2/layer3/m ls.htm which gives a little bit of details on this. > In the second configuration, instead of MLS we're using CEF and the > MSFC2 config looks just like a router with multiple interfaces running > CEF. There are no MLS-related configuration commands needed. Hmm...at > the moment I'm actually having a hard time differentiating between the > operation of MLS and CEF in this context. Yes, but in CatOS, you can still do the MLS commands, there just isn't anything there because it's not running MLS anymore. Even stranger, you can look inside CEF on the MSFC2 with "show ip cef internal" or whatever your favorite CEF command is *AND* you can also do a "show mls cef" or something like that under CatOS. I find this extremely strange. I would guess that with the Sup IOS architecture you will be able to attach or exec commands on the OSM cards or DFC-enabled line cards to show their CEF table. But I don't think you can with the CatOS MSFC IOS. > I think I need to brush up on MLS (since I haven't researched it since > last year) and then read through CCO to see how they're implementing CEF > on these switches. Don't worry about MLS unless you already have SUP1A's. If you are considering buying soon, don't evaluate the older product, just evaluate the SUP2 MSFC2 for Layer 3 switching. And go with Sup IOS, since that's what is going to be supported in the long run.

Cisco 2502 - home lab [7:10019]
Hi Group! I am planning to buy a CISCO 2502 Router at ebay from a reputed seller. This unit has 16MB RAM, 8MB FLASH, 12.0(17) IP/IPX/AT/DEC Feature Set. Comes with Token-Ring Media Filter. I would like to know if there are any major drawbacks on this model or if the above config seems vague. Please let me know if this is sufficient for a home lab?? Can I have any suggestions as to what Router I should use to set up my home lab. for my CCNP,IE prep.

Re: Theoretical vs. Actual Bandwidth - Refining the Question [7:10017]
It's not as simple as it sounds, of course. ;-) A good start might be Cisco's Technology Overview here: http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/index.htm That document shows typical header lengths for Frame Relay, ATM, ISDN, PPP, HSSI, SMDS, SDLC, etc. Search the group study list for more on Cisco's HDLC header. The HDLC frame format has been published here a few times. The exact header lengths will depend on which variety of each protocol you're using. For example, ATM headers are longer with AAL3/4 than with AAL5?? (I'm not an ATM expert.) Frame Relay fragmentation headers are different than vanilla Frame Relay headers. You probably would want to account for other protocol info that is overhead: call setup, signalling, SLARPs, LMIs, etc. Then, lest we forget, the equation depends on how much payload the upper layers put into frames. HTTP typically uses 400-600 byte packets, as do many database applications. Voice uses 64-byte packets. Terminal applications (like Telnet) use 64-byte packets. (A user types the letter A. The letter A is echoed back, and the echo is acknowledged.) Large frames (1000-1500 bytes) are typical of file transfer activities, such as saving files, executing applications, loading word processing documents, using FTP, etc.. E-mail is pretty impossible to predict. Attachments would use large frames. Message are hopefully small, but sometimes they are like this message. ;-) Then how about upper-layer overhead such as TCP acknowledgements? The number of ACKS depends on window size. Any retransmissions? And what else uses bandwidth? Routing protocols? Network management? Tunneling? RSRB? So Maybe just believe the SE who told you to assume about 25% is overhead, unless you want to do a real traffic analysis? ;-) 25% seems believable to me. How expensive is bandwidth? A real analysis might be worth the work... Sorry for all the hand-waving, but I'm in a bit of a rush. Hopefully you see the issues though.

RE: Way off subject [7:9997]
I've found the responses to this thread extremely interesting because I feel they relate directly to experiences in my career path. Here's a perspective from the other end. I am 23 years old. I am currently a CNE, MCSE, CCNP, CCDP, and CCIE #6080. I personally don't put a great deal of stock into an individual solely on certification however I know employers do weigh this information. I completed my Associates Degree in the Air Force but still haven't finished my engineering degree. Attaining these certifications opened many doors for me and allowed me to gain a wealth of experience in many cutting edge technologies with both enterprise and service provider companies. I strongly believe these certifications have influenced employers to give me opportunities that my youth would normally deny. I also believe that these certifications (and the experience I have gained because of them) give me an edge when competing for a job against others without certification or experience. Don't get me wrong. I think it is very true to say a college degree will last forever and is beneficial in the long run however I strongly feel my professional career has been greatly accelerated due to the career path I have chosen. I don't regret putting industry certifications before college at this time (except for those wild college parties I've heard about!!). However, I am continuing my education and plan to finish my degree in a couple of years.

Re: Snoop details [7:9944]
I found the documentation on what the last byte of a NetBIOS name means. Though it's not very "user friendly," here it is: redirector name main user name alias name server name This leads me to believe that RND is a workstation running a redirector, which is normal. I think it is quite odd, however, that the CDTOWER server sends a datagram to the RND workstation as a broadcast. If the server were using port 137, which is often used for naming announcements, then it wouldn't be weird. But it's using port 138. NetBIOS ports are: 137 Name Service 138 Datagram Service 139 Session Service So what might cause CDTOWER's TCP/IP stack to think that 192.65.2.255 is a broadcast? (What might have caused the stack to tell the data-link layer to send the frame to the broadcast address?) CDTOWER's own IP address is 192.65.2.192. We can't tell the subnet mask from the frames, but anyone have any theories? It's good practice in bit-twiddling. There are many possibilities. How CDTOWER got the IP address for RND to start with is another (harder) mystery Priscilla At 04:09 PM 6/26/01, Priscilla Oppenheimer wrote: >2100 broadcasts in 30 minutes might be OK, actually.

FW: Way off subject [7:9997]
Here is $.02 worth from someone twice your age. Go to school. Go directly to school. Do not pass go. I say that for these reasons. From your email you think you want to go to school, so that is a great reason. Also the CCIE will still be a long term goal. At your age, a degree is very important. A college degree will help you get your first job or two and they can never take it away from you. The older you get the harder it will be for you to finish school. Another advantage might be that the study habits you acquire in college will help you with your CCIE studies. I have worked with High Schoolers for 20 years and have not seen any be hurt by getting a college degree and many still working for peanuts because they did not go on to school. Listen to yourself, pray, find someone you respect and have this conversation with them. You will make the right choice.

RE: ACPC @ Globalknowledge [7:9971]
Bryan, They are excellent preparation for the CCIE lab but my opinion might be a little biased seeing as I'm the developer of the ACPC classes ;) The classes are geared toward students who are about 3-5 months out from their lab date. There are three ACPC classes, ACPC1, ACPC2 and ACPC3. Each class focuses on different technologies. The classes are run Monday to Friday from 8:30am till 10:00pm with the instructor remaining with the class the whole time (lunch and dinner excluded). The current instructors are myself and Paul Borghese. Students get access to the equipment 24x7 during the week of the class. The console server is setup so it's accessible via the Internet. Currently we are giving access to the equipment over the weekend after class. This gives students additional time to redo labs, practice additional scenarios, etc. The main objective of the classes is for the student to achieve a full understanding of the technologies needed to become a CCIE.

Re: Way off subject [7:9997]
College counts SO much more than certifications (which expire). College degrees do not expire. I went through the same thing in college getting my Novell Certification while working and studying college. Just look at it now...my college degree still gets me a job but being certified in Novell 3.11 doesn't count for much at all these days ;) Focus on college primarily and if you have free time, work on your Cisco certs then. You've got a year and a half along with breaks between semesters to do that. Dedication will pay off if you stick with it.

Re: Catalyst 6500 Confusion [7:9983]
Thanks, that does help to clear some things up...sort of. :-) Let me see if I really understand the differences between Sup1A+MSFC and Sup2+MSFC2. In the first configuration, the Sup1A can use CatOS or SupIOS. The MSFC operates as the MLS-RP and the Sup1A is the MLS-SE, right? InterVLAN traffic is routed initially by the MSFC until a flow is established, at which point the rest of the flow is hardware switched. In the second configuration, instead of MLS we're using CEF and the MSFC2 config looks just like a router with multiple interfaces running CEF. There are no MLS-related configuration commands needed. Hmm...at the moment I'm actually having a hard time differentiating between the operation of MLS and CEF in this context. I think I need to brush up on MLS (since I haven't researched it since last year) and then read through CCO to see how they're implementing CEF on these switches. If Cisco is moving toward using only the SupIOS, I may have to start thinking of the 6500 as a router with a bunch of switch ports instead of a switch with some L3 routing functions built in. :-) thanks, John >>> "dre" 6/26/01 1:49:37 PM >>> ""John Neiberger"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Okay, I'm thoroughly confused.

The original SUP1 MSM architecture of the Layer 3 Catalyst 6500 is different than the SUP1A MSFC architecture is different than the SUP2 MSFC2 architecture. You can use the MSFC2 on the SUP1A, but you don't get the advantage of CEF in Layer 3 switching like you would with the SUP2 MSFC2 combination. SUP1A has to use MLS. SUP2 has to use CEF. In the SUP2 MSFC2 architecture, CEF is downloaded from the MSFC2 to the PFC2 (another card on the SUP2), so CEF now forwards in hardware. This happens whether you are running CatOS (Hybrid) or Sup IOS (Native). If you are using DFC-enabled linecards, the CEF table is also downloaded to each DFC (there can be up to two per linecard, depending on which ones you are using). It is actually even more complex than this, but I don't want to make your head spin. The only real difference between CatOS and Sup IOS is support and features. CatOS + MSFC IOS is currently the software for the SUP2 MSFC2 architecture. This is changing in the next three months. Everything currently only works properly for SUP2 MSFC2 under CatOS. But three months from now, Cisco is changing directions with the product and moving completely to Sup IOS. All future work will be done for Sup IOS, but it is not available fully yet. The newest features are being developed for Sup IOS like EoMPLS (which Cisco demonstrated on the Catalyst 6500 / 7600 OSR at SuperComm). I believe that the Catalyst 6500 / 7600 OSR is the only product currently supporting EoMPLS (or any of the AToM technologies), even though it doesn't yet support MPLS-TE or MPLS-VPN. More details on EoMPLS are available at http://www.cisco.com/warp/public/cc/pd/rt/7600osr/prodlit/emp76_tc.htm > I see that the MSFC2 can do 650 Mbps+ of software-based forwarding.

MSFC2 only does forwarding when there are no MLS entries in the cache, yes, but this only would occur on the SUP1A architecture. With SUP2, the MSFC2 would only do forwarding when there are no CEF adjacencies or when packets are not-cef-switched (first packet generally). The benefit of having the Catalyst 6500 would be to use MLS with SUP1A whenever possible and CEF with SUP2 (or to the DFC-enabled linecards) whenever possible. This maximizes performance, because it's all done in hardware forwarding. > We have a lot of interVLAN traffic and my worry is that as traffic > volumes increase that our performance will suffer due to restraints > present in the MSFC.

Re: Theoretical vs. Actual Bandwidth - Refining the Question [7:10001]
Ah, this is one of those cases where I wasn't really answering the question you were asking. :-) Sorry about that! I know I have some information like that around here but I can't find it at the moment. Perhaps some of the listmembers that are more versed in network analysis than I could provide some links. If I can find the links that I've used in the past for this type of information, I'll let you know. Regards, John >>> [EMAIL PROTECTED] 6/26/01 2:04:07 PM >>> You're comparing apples to oranges. A 10BaseT LAN is a shared medium, which explains the oft-quoted-but-not-quite-accurate 40% max usage figure. The theory is that with CSMA/CD, as traffic increases so do collisions, which forces retransmits. This is exacerbated in a half duplex environment. Dana's Comment - I realize that LAN and WAN environments are different. I was just using the 10Mb quote as an example. WAN links, such as a T-1, are synchronous (or isochronous or pleisochronous or some other x-ochronous word that I don't understand) full duplex connections. This means that frames are travelling boths directions over the link at the same speed regardless of the amount of traffic to be carried. In the case of a T-1, if you have 1.536 Mb/s of data to send, then go for it. The bandwidth is there if you need it. For you hair-splitters, I'm purposefully not getting overly detailed. Of course, you have to factor in packet headers in your calculations. Any data you have to send has to be encapsulated first. If you're using IP, then any data packets must be encapsulated with a UDP or TCP header and then with an IP header. This packet then must be placed inside whichever datalink frame you're using, whether it's Ethernet, HDLC, PPP, or whatever. All of this creates overhead that you have to take into account when calculating how much bandwidth you actually have available. Dana's Comment - On WAN links, I just was wondering how what percentage I should give to headers, framing, signaling, etc. One Cisco SE told me that I should calculate 25% to cover those issues. I.E. On a 512K link I could only expect 384K of usable bandwidth. I figured that different technologies should have different percentages - ATM vs. ISDN vs. Frame Relay etc. That is what I am looking for is specifics per technology as opposed to a general WAN figure. I hope these notes clarify my question. But the moral of the story is that point-to-point WAN links suffer from different issues than CSMA/CD networks.

Rollover cable needed . [7:9910]
You might even have since it probably came with a router. It is a light blue flat cable with RJ45 connections that has an RJ45 - DB9/DB25 interface on one side. If you carefully looked at the cable ends you would notice that the wires are positioned in oposite directions (kind of like a null modem cable - because it is used for the same purpose). -- Nick Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=&t=9910 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Snoop details [7:9944]
2100 broadcasts in 30 minutes might be OK, actually. Can you tell us how much bandwidth they are using? Can you tell us what percentage of the packets are broadcasts? A rule of thumb that Cisco teaches is that no more than 20% of your packets should be broadcasts. The main problem with broadcasts is that they interrupt station CPUs, but with the high-speed of CPUs these days, that is less of an issue. You seem to be running NetBT, which is NetBIOS over TCP/IP. (NetBEUI is NetBIOS running directly on a data-link, which is not what you are running.) NetBIOS sends lots of broadcasts. In this example, the server CDTOWER is sending a broadcast. You need to find out if that is necessary on your network or not. It seems a bit odd that CDTOWER is sending the frame directly to RND at the NetBIOS layer but to a broadcast address at the network and data-link layers. Sometimes a subnet mask misconfiguration can cause such a problem. Check CDTOWER and RND's configs. The last byte of a NetBIOS name tells you what kind of device it is. CDTOWER ends with x20, which means server, if I remember correctly. RND ends with 0x0 and I have forgotten what that means and my NetBIOS documentation is packed away. But you could find this somewhere on the Net or one of our esteemed colleagues probably knows. I don't recognize the other broadcast packets. They have an 802.3 length field of 0 even though there's data in the packet. It sounds like a bug? Would it be possible to find the station sending them (0:8:c7:d2:4a:ab) and check its configuration?

Way off subject [7:9997]
Im in a dilemma. I need some career advice from some experienced professionals and anyone else that has been on the same road. I am 22 years old I have one more test (CIT) to complete my CCNP. I have been planning on studying for the CCIE and taking the lab within the next year and a half but Im not sure now. My problem is that I want to get my computer science degree and I dont think I can get both and work at the same time. I am about 2 and a half years from graduating. I also work 40 hours a week as a computer tech for an elementary school. I have hands on experience with cisco only in a lab enviroment, not in a production network. I feel confident that I want to keep learning networking, but at the same time I feel I am missing something by not having a degree and not having a broader understanding of computer systems. The longer I work and put off school I know it will be harder for myself to get the degree. Now I am deciding to go to school full time (after I save up some money) and get the degree done. I guess the only reason I feel hesitant about doing this is because I am getting closer to getting the CCIE and that has been my focus for the last year and a half. But I have been thinking about it and I think having the degree behind me will help in the long run if I want to go into management or if I decide to maybe get into network programming (which I know nothing about but am kinda curious to learn). Part of me wants to get into the field now, but the logical part of me is telling myself to wait and get the degree. I dont want to get a cisco related job while going to school because that will postpone myself getting the degree or take away from my job because I am focusing on school.

Theoretical vs. Actual Bandwidth - Refining the Question [7:9996] Re: Theoretical vs. Actual Bandwidth [7:9961]
You're comparing apples to oranges. A 10BaseT LAN is a shared medium, which explains the oft-quoted-but-not-quite-accurate 40% max usage figure. The theory is that with CSMA/CD, as traffic increases so do collisions, which forces retransmits. This is exacerbated in a half duplex environment. Dana's Comment - I realize that LAN and WAN environments are different. I was just using the 10Mb quote as an example. WAN links, such as a T-1, are synchronous (or isochronous or pleisochronous or some other x-ochronous word that I don't understand) full duplex connections. This means that frames are travelling boths directions over the link at the same speed regardless of the amount of traffic to be carried. In the case of a T-1, if you have 1.536 Mb/s of data to send, then go for it. The bandwidth is there if you need it. For you hair-splitters, I'm purposefully not getting overly detailed. Of course, you have to factor in packet headers in your calculations. Any data you have to send has to be encapsulated first. If you're using IP, then any data packets must be encapsulated with a UDP or TCP header and then with an IP header. This packet then must be placed inside whichever datalink frame you're using, whether it's Ethernet, HDLC, PPP, or whatever. All of this creates overhead that you have to take into account when calculating how much bandwidth you actually have available. Dana's Comment - On WAN links, I just was wondering how what percentage I should give to headers, framing, signaling, etc. One Cisco SE told me that I should calculate 25% to cover those issues. I.E. On a 512K link I could only expect 384K of usable bandwidth. I figured that different technologies should have different percentages - ATM vs. ISDN vs. Frame Relay etc. That is what I am looking for is specifics per technology as opposed to a general WAN figure. I hope these notes clarify my question. But the moral of the story is that point-to-point WAN links suffer from different issues than CSMA/CD networks. Dana's comment - John, thanks for your comments.

The original SUP1 MSM architecture of the Layer 3 Catalyst 6500 is different than the SUP1A MSFC architecture is different than the SUP2 MSFC2 architecture. You can use the MSFC2 on the SUP1A, but you don't get the advantage of CEF in Layer 3 switching like you would with the SUP2 MSFC2 combination. SUP1A has to use MLS. SUP2 has to use CEF. In the SUP2 MSFC2 architecture, CEF is downloaded from the MSFC2 to the PFC2 (another card on the SUP2), so CEF now forwards in hardware. This happens whether you are running CatOS (Hybrid) or Sup IOS (Native). If you are using DFC-enabled linecards, the CEF table is also downloaded to each DFC (there can be up to two per linecard, depending on which ones you are using). It is actually even more complex than this, but I don't want to make your head spin. The only real difference between CatOS and Sup IOS is support and features. CatOS + MSFC IOS is currently the software for the SUP2 MSFC2 architecture. This is changing in the next three months. Everything currently only works properly for SUP2 MSFC2 under CatOS. But three months from now, Cisco is changing directions with the product and moving completely to Sup IOS. All future work will be done for Sup IOS, but it is not available fully yet. The newest features are being developed for Sup IOS like EoMPLS (which Cisco demonstrated on the Catalyst 6500 / 7600 OSR at SuperComm). I believe that the Catalyst 6500 / 7600 OSR is the only product currently supporting EoMPLS (or any of the AToM technologies), even though it doesn't yet support MPLS-TE or MPLS-VPN. More details on EoMPLS are available at http://www.cisco.com/warp/public/cc/pd/rt/7600osr/prodlit/emp76_tc.htm > I see that the MSFC2 can do 650 Mbps+ of software-based forwarding. Is > this only referring to first-time routing of packets when no MLS entries > are present in the cache? If there are cached entries are they > hardware-forwarded or are we still limited by the performance of the > MSFC? MSFC2 only does forwarding when there are no MLS entries in the cache, yes, but this only would occur on the SUP1A architecture. With SUP2, the MSFC2 would only do forwarding when there are no CEF adjacencies or when packets are not-cef-switched (first packet generally). The benefit of having the Catalyst 6500 would be to use MLS with SUP1A whenever possible and CEF with SUP2 (or to the DFC-enabled linecards) whenever possible. This maximizes performance, because it's all done in hardware forwarding. > We have a lot of interVLAN traffic and my worry is that as traffic > volumes increase that our performance will suffer due to restraints > present in the MSFC. As long as everything stays in MLS (SUP1A) you will be ok. There is a hashing algorithm problem that causes a maximum of 128k destination-only based flows, but many people have found that realisitically this number is much lower due to a hash collision that will result in packets forced up to the MSFC (1 or 2, doesn't matter). More details can be found at: http://www.cisco.com/warp/public/473/35.html (at the bottom of the page). Setting destination-only based flows (the default) and by tuning with MLS fast aging, you can possibly acheive up to 128k flows in MLS. The MSFC will handle a lot of packets, still, however the performance is not optimal compared to MLS. Even better would be to use SUP2 MSFC2 with DFC-enabled linecards. They do not suffer from the problems of MLS and things like OSPF ECMP work a lot better using CEF. The performance of CEF is much better. Also, SUP2 MSFC2 with Sup IOS seems to be the product's overall direction. > Without IOS and CEF, once the MLS cache is populated, aren't any > further packets hardware switched?

Re: Dual T1's and failover with static routes [7:9979]
Sure, no problem! If you have two different equal-cost routes to the same destination, the router has a few options when deciding which path to choose. These options are called switching modes, and the two most basic are called process switching and fast switching. Process switching performs per-packet load balancing. This means if you have a stream of packets going to the same destination, the router will alternate between the possible outgoing interfaces on a per-packet basis. This is fairly processor-intensive. Fast switching performs per-destination load balancing. In this mode the first packet of any given stream is process switched. The router takes note of that particular destination and exit interface and puts this information into the fast switching cache. Any subsequent packets destined for that same destination are sent out of the same interface. Using this method, the router roughly divides the number of destinations between the two available exit interfaces. Fast switching is quite a bit less processor-intensive that process switching. In your situation, per-packet load balancing could cause some problems. Fast switching would seem to be the way to go. Does that help? I kept getting interrupted while typing this so I hope it makes sense. Regards, John >>> "Sam Sneed" 6/26/01 11:59:01 AM >>> I'm not exactly sure what you mean by "per destination load balancing".

Theoretically, those two ISPs could make arrangements to let you keep the old IPs. However, it is going to be a big hassle and you would find it not worth the effort.

Re: Dual T1's and failover with static routes [7:9979]
I'm not exactly sure what you mean by "per destination load balancing". I'm am new to Cisco products so some of the terminology is over my head. Could you clarify this for me with the commands I would use? Thanks alot. ""John Neiberger"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Sure, you can do this. But why?

Catalyst 6500 Confusion [7:9983]
Okay, I'm thoroughly confused. I'm doing some research on this platform because we'll be purchasing one later this year or early next year. The documentation seems to be quite murky and the more I read, the less clear the picture is. I see a few different issues that I need help with. The first is software. Which one to use? CatOS? Supervisor IOS? If I can only do CEF with IOS, then if we get CatOS are we totally hosed and limited to software forwarding of interVLAN traffic? I see that the MSFC2 can do 650 Mbps+ of software-based forwarding. Is this only referring to first-time routing of packets when no MLS entries are present in the cache? If there are cached entries are they hardware-forwarded or are we still limited by the performance of the MSFC? We have a lot of interVLAN traffic and my worry is that as traffic volumes increase that our performance will suffer due to restraints present in the MSFC. Without IOS and CEF, once the MLS cache is populated, aren't any further packets hardware switched? If that's the case, I don't see much need to get the Sup IOS. I seem to remember someone complaining about the Sup IOS but I don't remember the details. Hmm...I suppose I ought to check the archives, huh? :-) Anyway, any help anyone could offer would be greatly appreciated!

Re: Dual T1's and failover with static routes [7:9979]
Sure, you can do this. But why? Why not use per-destination load balancing instead of paying for an unused link? To achieve your goal, do exactly as you stated. Setting the AD higher on one of the static routes will do what you want. To answer the last question, if a directly connected interface goes down then all routes that exit that interface are immediately removed from the routing table. In the case of floating static routes, the change to the backup default will be instantaneous. HTH, John >>> "Sam Sneed" 6/26/01 11:08:32 AM >>> Currently my internet connection is a Cisco 4700 with 2 frame relay lines. We do load sharing by having 2 default routes through each link. ip route 0.0.0.0 0.0.0.0 Serial0.1 ip route 0.0.0.0 0.0.0.0 Serial1.1 This works quite well but we only want to use one link and have the other for backup so our ISP will charge a lower rate. I also want to stay away from using routing protocols.(its a small network). Will this work: Assign a greater adminstrative distance to one of the default routes so it will never be used over the desired default route unless the desired link goes down. Also how long does it take for a directly connected route and static routes assoicated with an interface to disappear from the routing tables?
