my VoIP box on ebay
I've never spammed the list before with stuff I am selling but I am quite proud of this 1750 - specifically: 1750-2V, 48 meg of dram, PVDM-4, vic-2fxs, wic-1t, wic-1b-u - VoIP, sync serial, and ISDN all in one neat little package. The only way this could be better is if the 10/100 port on the 17xx would do ISL or 802.1Q - they DON'T - so don't buy it thinking it'll do VLANs along with all the other neat stuff it has installed. http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1218538608 I'd rather see someone on here get it than have it go to some equipment dealer who will part it out. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
MC3810 == must have toy!
I got an MC3810 a while ago on a trade and I haven't had much time to mess with it. I couldn't stand the suspense any more so I took it apart this evening just to get an idea of what it can do. The base chassis has a 10 meg ethernet port and two DB60 serial ports just like a 2501. The processor is a 40 MHz risc chip so its on par with the 2610 in terms of performance. It has a single flash slot and a single dram slot. There are some good diagrams of the insides on this link: http://www.cisco.com/univercd/cc/td/doc/product/access/multicon/3810fru.htm The expansion slots are what makes this router so cool - you get a video dialer slot for RS366 which is essentially useless but the other four expansion slots are very interesting. The video dialer slot is next to the power supply, the slot next to the left holds a DSP for voice compression, the next slot can take a variety of Multiflex trunk cards, and the far left two slots can take a DSP and an MFT like the ones on the right or you can install a six port pots card that will do FXO, FXS, or E&M. I already had an MC3810-MFT-T1 I'd gotten with a previous package of Cisco stuff and the MC3810 I bought for $1100 had the same T1 module and the MC3810-VCM6 DSP module. I own an pair of Adtran TSU 600 T1 channel banks with dual FXS ports - I can configure the 3810's T1 port and use a pots phone plugged in to the channel bank to do VoFR, VoATM, and VoIP. I started digging to find out what other goodies you can put in a 3810 and I was amazed to find this gem - the MC3810-MFT-TBS - this card has a T1 MFT port and an ISDN S bus just like the 2503. You can find a full list of parts for the MC3810 here --> http://www.cisco.com/univercd/cc/td/doc/pcat/mc3810.htm At the moment I have in my lab a Cisco 2521, a Cisco 2511, a Cisco 2525 /w ISDN, and this 3810. I am done with CCNP/CCDP and my next step is voice specialization. I think I am going to add another 3810 and make sure it has two MFTs and that one of those MFTs has the ISDN option - that will get me VoFR, VoATM, VoIP, and it'll fill my quote of ISDN boxes for the CCIE lab prep. If you're just getting started on Cisco certs all I can say is KEEP PUSHING. I've been studying for two years and I am amazed at the cool stuff I get to do now that I've got the CCNP/CCDP out of the way. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: MC3810 == must have toy!
The MC3810 bug bit me real hard today - I picked up another MC3810, brought it home, and got busy cleaning up the debris from my CCNP/CCDP. At the end of the day I kept a 2511, a 2525 with a sync serial port, a MC3810-V with a T1 port and DSPs, and a MC3810-3V with T1 port. I hung all of the routers in my rack and then I stuck two Adtran TSU 600 channel banks under them. The TSUs are lightly populated - only two FXS ports in each but that is plenty for one person doing VoX experiments. You can see a picture of the current setup here http://members.home.com/puzzled/voicelab.jpg You're right to guess this isn't complete - the 3810-V3 seems to allow VoIP without the hardware DSP module installed but I haven't been able to get it to run yet - I suspect I'll end up with a DSP expansion card before too long. I'm also going to add a T1/ISDN modules to each router. I'll have one port for TDM voice and then I'll hook the second T1 port in each router back to back so I can do VoATM - this is *the* cheapest method to get hands on with that technology. I knew I liked this first 3810 when I brought it home but the T1/ISDN card is the clincher - VoATM and a much needed ISDN port all in one small package. Is anyone else running these things in a lab environment? I'd like to hear what sort of fun others are having with them ... post configs if you've done something interesting. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
CID passed with 839, CCDP complete, details inside
100 questions, took me 32 of 120 minutes allowed, and I walked out with an 839 and my spiffy new CCDP :-) The exam has the following sections and I've listed my scores 1 Intro to Internetwork Design62% 2 Campus LAN design62% 3 TCP/IP network design88% 4 desktop protocol design80% 5 WAN design 76% 6 SNA design 71% 7 security issues 0% (!)(more on this below) For prep I used the Cisco Press CID book and the boson.com pretest. I spent about a month after completing my CCDP just letting my brain cool off then I crammed for the CID in about two weeks. The BCMSN material does an excellent job of covering the Campus LAN design portion, BSCN takes care of the TCP/IP network design, and BCRAN covers a bit of the WAN design questions. I studied for the CCNP 1.0 track and I took the ACRC exam last spring and missed it by one question. I mostly took it to get that stuff out of my head so I could work on switching and I didn't bother to retest but I feel that working through the Sybex ACRC book and the IPX and Appletalk labs in the CCIE Lab Study Guide really carried me on that portion. The information in the Cisco Press book is NOT I repeat NOT sufficient - you really need ACRC level skills to get by this thing. There are a number of questions on Stratacom stuff in the WAN portion. On pp367 of the Cisco Press CID book you will find this URL http://www.cisco.com/univercd/cc/td/doc/product/wanbu/82/switch/sysm/sysmch01.htm Learn all of the magic incantations on this page and you will be protected from the ATM demon during your 640-025 exam :) I am a big fan of mastery rather than rote learning but in this case the boson.com exam proved invaluable - their questions are very, very close to what you'll find on the actual exam and you can practice test your way to a passing grade if you need to do so. As gross and as useless as it is for 92% of the people working on this certification, you *must* know a little bit about SNA. I had done workstation support in a huge SNA shop so it wasn't entirely foreign and a long time ago (5+ years), for reasons I forget, I purchased and read a large portion of Communications for Cooperating Systems - OSI, SNA, and TCP/IP. This book is a psychotic piece of IBM backed propaganda which argues for the subordination of TCP/IP and the OSI model in the perfect (I use the word in the facist sense) SNA world. If you can shield your mind from the IBM borgification procedures its actually not a bad read if you want to get some background on SNA. FWIW it is ISBN 0-201-50775-7 and my copy was 'updated with corrections' in 1992. If you don't have the aforementioned marvelous tome of IBM wisdom the CID book covers a lot of what you need to know. The 0% on security was quite a suprise and I still wonder if it isn't a misprint from the test software based on my final score- I was a script kiddie way back when before there was even a word for it and I am very used to looking at other's stuff with a probing eye. I guess the mindset of those that are trained to defend is a lot different than that of those of us who took the Wyatt Earp route to getting our sherrif's badge. Good luck, good studying, and if you're tired of people 'borrowing' your linux box take a look at www.openbsd.org - its the best script kiddie repellent I've found so far. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Cisco 100x WILL do OSPF/BGP using IPv6 image
I don't know if anyone else noticed but there *IS* an image for the little Cisco 1000 series boxes that does OSPF and BGP. I am running the old 11.3 based IOS IPv6 beta image and it works great. The 12.0 based IPv6 image, besides being too large to fit on the 2 meg flash you find in the cheapest of 100x routers, corrects this 'deficiency' by only providing rip, igrp, and eigrp. So, you heard it hear first ... now watch the prices on those Cisco 1005 auctions zm on the good news. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
IPv6 connection offer
I changed jobs a few months back and as part of my new duties I get to learn a lot about IPv6. I have a Cisco 7206 VXR 300 that is dedicated to being an IPv6 access point. The router is part of AS12023 and its connected via ethernet to our border router that peers with UUNet (AS701), Teleglobe (AS6453), and Level3 (AS3356) - it should provide a fast, stable 6bone connection. I will provide to anyone who connects the following: 1. an IPv6 in IPv4 tunnel 2. a /60 of IPv6 addresses that are globally routeable 3. an internal BGP peering session to AS 12023 4. telnet access to the core router to help with troubleshooting 5. my office phone number and my VoIP target + destination code for 0800-1700 tech support The way I am setting this up it should be a good play for intermediate/advanced students who want to hone their BGP skills and learn a little about IPv6. If you're the type that likes book learning before you actually put your hands on something I can recommend IPv6 second edition by Christian Huitema ISBN 0-13-850505-5. I've picked up quite a few IPv6 books and almost all of them I found to be filled with fluff. Huitema's book is a solid read you can place on the shelf between Caslow and Halabi for ongoing reference.

Re: Lot of talk about 3548; but is it a VLAN router like the 5000?
As a minimum you need a Supervisor III with a NFFC. The NFFC is a WS-F5521 as opposed to the more expensive NFFC2 WS-F5531/5531A daughtercard. You can use an external router to do the job that the RSM does different environments but you can learn enough to pass using a 2620 as the external RP. There are some differences with ethernet cards as well - WS-X5224 24 port 10/100 blade does not do inline rewrite, WS-X5225 does ... inline rewrite basically transfers the packet rewrite functions of the NFFC/NFFC2 to the level of ASICs in the card. Its not on the test but its a big issue if you're trying to use a 55xx box with its limited backplane. All the 65xx linecards support inline rewrite. I used to work for a reseller that is very active in the education market ... here is some design/pricing wisdom for you. As a base I'd buy a WS-C5505 chassis, a WS-X5530-E2 supervisor, and a WS-X5213A blade. Don't buy a WS-X5213 - won't work in a 55xx chassis even though they physically fit. The chasis is $1950 new in distribution, the 5213A is not more than $1k, and the engine should be not more than $5k. It costs $2100 to upgrade a WS-X5530-E1 to the latest/greatest and those cards can be had for $1500 if you dig ... but keep in mind I am digging, too, and I don't have an approval process to go through when I buy :-) For the RP I'd go with a 2620 if you want something you can put a voice card into later or if you've got an NP-1FE in one of those 4500s you're already set.

HSRP, NAT, OSPF - real world troubleshooting
I had something kind of ugly happen at work today and I thought I'd share the details. I have two DS1s in our office that leads to our border 7206 which is in a colocated rack. One runs to a 2611, the other to a 2621. I have two Cat 3524s tied together with a copper gigabit link. They have two VLANS - #2 is 10.10.1.0/24 and #5 is xxx.xxx.21.32/27 The 2611 has one interface plugged into VLAN2, the other into VLAN 5, while the 2621 uses an 802.1Q trunk to one switch that carries both VLANs. Both routers back each other up via HSRP - the 2611 is primary for 10.10.1.0/24, the 2621 is primary for xxx.xxx.21.32/27 - thus load balancing the traffic across the two DS1s. Both routers run OSPF. Everything is in area 0 and there are three other sites that are fed from the core 7206 via DS1s. Nothing else was happening at the other sites when my trouble occured. I have a NAT pool on each router. The 2611 was there when I started and it originally had some numbers pulled out of the air with a static route from the 7206 to the particular serial interface so they were reachable. I got tired of wrestling with that config and stole .61 and .62 from xxx.xxx.21.32/27 to use instead. When I brought the 2621 in I created a loopback 1 interface and attached xxx.xxx.21.240/32 to it and used the middle two addresses for the NAT pool. I did this so I could *see* which subnets were used where. Loopback0 on each router is a /32 taken from the top of the xxx.xxx.21.0/24 - the 2611 is xxx.xxx.21.252 and the 2621 is xxx.xxx.21.247 - this is done so we have stable router IDs in OSPF for those of you who haven't read that chapter yet. The interface on the 2611 that carries the public numbers got plugged into a port that was in the wrong vlan. The port was up/down and I didn't notice when I left on Sunday after having just converted from a 100 mbit link to the gigabit connection. This led to a couple of interesting consequences. Both of the routers private addresses were reachable via telnet from the inside and once there I could see everything else in the network but stations on the inside could not reach anything. The DNS server for our network lies on the public segment that was not reachable via the 2611 and the addresses used for NAT came from the downed interface. With the 2611 being the active HSRP interface it couldn't see DNS and it was using numbers from a network that our core router believed to be reachable only through the 2621 ... which was not where the NAT sessions were occuring. I spent two hours digging on VLANs and other stuff before I noticed the interface to the public LAN on the 2611 was up/down. I knew I liked the Loopback interface on the 2621 holding the NAT pool a lot better than stealing from the public segment and I am going to make that my policy now on any router that has to do NAT. I may find a good use for a /31 yet :-) I also screwed up on interface tracking - I tracked the DS1s which was a good thing but in a setup like this I believe the public LAN interface needs to be tracked as well. I don't know if HSRP will let you track multiple interfaces but I am going to find out as soon as I click send for this message. Take heed, your CCIE wannabes, and demonstrate your problem solving skills to the lab examiner instead of while standing in front of twenty grumpy coworkers who want to know why they can't get their email :-( _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
BCMSN passed with 934, details inside
I took the BCMSN this afternoon and exited the testing center with a very surprising 934. Background: I have a couple of years time in grade with cat 19xx/28xx, about the same more recently with 29xx/35xx, and I once worked for three months on an incredibly psychotic Cat 5500 with 800 MACs in the cam and one subnet(!). I've also done one Cat 5500 + NFFC + RSM layer 3 deploy to an ISP with 40k worth of public IPs being routed through the switch. Study gear: I had two Cat 3524s running enterprise attached to a Cisco 2621 running 802.1Q VLANs in production at work. I had a loaner Cat 5000 with a Sup 1 and a ws-x5213 for the last few weeks of my studies. There was an idle 7206 in a remote facility that I used to brush up on mls rp commands. I did some multicast work with my 25xx collection at home. Study Materials: Didn't refer to Caslow once(!). The Cisco Press BCMSN book (only a few errors) and the official Cisco Press LAN switching were all I used. The LAN switching reference does an excellent job of covering some items that the BCMSN gives what I felt was a lightweight treatment. The boson.com pretests were *excellent* - my only gripe is that what is in boson's stuff is *way* harder than the real thing - I was getting mid 60% on the boson stuff and I thought I'd squeak by the exam ... the 934 was a huge surprise. What to watch for on the exam: I think the BCMSN question base is *very* broad. I've talked to folks that had to examine network sniffer traces and so forth and I saw none of that. The possible broadness being mentioned the details are ... Pound VTP operations into your head and do it twice for that stuff about version numbers. Use the same amount of effort on spanning tree and VLAN configuration issues. MLS is there but if you *understand* the BCMSN chapter on it and then read the Cisco Press LAN Switching you'll be fine. I am amazed at how little there was on multicast - knowing how to convert an IP address to a MAC address covered 50% of what I saw. This makes me think the exam question base is broad because I've talked to others who got a lot of multicast questions. I really got flogged on Cisco product line knowledge. I worked for an equipment dealership and I've troubleshot/tested/sold/refurbed everything Catalyst from 1912s to 65xx series include all of the layer 3 modules and I was streeetccchheddd by what the test wanted to know. I can eyeball a box full of Cat 5500/6500 cards and tell you part numbers and specs on them - I rarely need to refer to the fact Cisco product guide any more - and I was really reaching on some of this stuff. If my experience is represenative you should call 800-553-NETS and order DOC-CISCOCATALOG= and memorize the 55/6500 layer three stuff before approaching the exam. Well, thats all the wisdom I have to offer at the moment ... I am going to go pounce on CIT and see if I can be a CCNP by this time Friday ..

CIT passed with 850 & CCNP done, details inside
I passed my BCMSN yesterday with a 934 and as a special present to myself I scheduled the CIT exam early this morning. I did basically zero preparation for the test. I spent the $30 for the boson.com exam for CIT because boson's stuff has been a very reliable indicator of readiness for me. I breezed through the first practice test in about nine minutes with a 70% and figured I was ready to go. I found the following areas covered in the exam 1. structured troubleshooting - collect some facts, try to isolate the problem, then an action plan. They must cover this in a structured fashion in the classes but I've never talked to anyone that has taken the CIT. There was a 'drag the little tabs into the appropriate order' question ... it was common sense. 2. ISDN. backwards and forwards. Caslow is a must read for this and I did all of the labs in the CCIE Lab Study Guide by Hutnik and Saterlee using a real live ISDN line into my house sharing the circuit between two S bus routers using an NT1. 3. frame relay. Once again Caslow and the CCIE Lab Study Guide will get you right through this. 4. IP and IPX behavior. I had a CNA and a lot of time in grade with netware and I've read W Richard Stevens TCP/IP illustrated so I had no trouble with this. 5. VLANs in all their glory. I feel *very* lucky that I scheduled this on top of the BCMSN instead of waiting and reviewing as I usually do. 6. there were a lot of subtle questions about connectionless protocols and troubleshooting in an internetwork that I did not do get. I am going to track that stuff down and read it for my personal satisfaction. I started working on the CCNP stuff diligently around April of this year after passing my CCNA last October and my CCDA in January. So, seven months of hard work, a killer home lab when I worked for Optimum and a not so killer home lab now that I am spending my own money, and maybe 500 hours of study and lab time and I'm now smart enough to accurately assess just how far I have to go for the CCIE :-( I got the boson.com exam for the CID earlier tonight and the results were promising :-) Am I going to be the first to knock off three of these exams in three days?

Mo' Better Kitty Rides Again! [7:3093]
I have two Catalyst 2926s that are ebay bound but I don't have time to put the auctions up at the moment so I put them up for a few days so some of you aspiring CCNPs who can't afford these toys get a chance to play. They can be reached at these locations with the userid and password both being 'ebay'. The switches themselves have no passwords for access or enable. 24.3.233.101 2007 24.3.233.101 2008 The switches are cabled back to back to each other via the first ethernet port on their supervisor engines and the unit at port 2007 has its 24th fast ethernet port plugged into my other ethernet stuff. I was in Optimum Data the other day and I saw a Cisco 4700 with a fast ethernet port in it. I am going to visit those guys later today and I'll see if I can borrow that box for a few days so this will be a complete lab. If I do borrow a router it'll be placed at 24.3.233.1001 2006.

Scary Kitty Mutation [7:3097]
I was rooting around in the debris field I call my office looking for my digital camera so I could auction those Catalyst 2926s and I came up with a pair of Catalyst 2600s - token ring switches. I got these things thinking they might be like the much feared Catalyst 3900 which has never been sighted anywhere other than a CCIE lab exam, but I don't think its the same thing - these switches drive just about like the old Grand Junction Catalyst 1900 switches. Anyway, there are two of them at these locations without any passwords: 24.3.233.101 2005 24.3.233.101 2006 If one of you scholars can forward me the pinout needed to cross token ring on an RJ45 port I'll whip up a cable for them.

I had to move about a dozen new boxed cisco 2610s to get to the shelf where I found this 4500 today and I counted about 75 25xx routers in the same area - I saw a lot of 2514s, 2521s, and I think a few 2523s - they have plenty of good stuff if you're trying to build your lab out.. I believe Michael Beacom ( mailto:[EMAIL PROTECTED] ) has been handling education sales since I left Optimum Data - you can reach him via their main number 800-879-8795.

Re: Having problem with tftp to flash : URGENT [7:3455]
Your very urgent problem is going to require NEW BOOT ROMS for your 26xx. I have encountered this bug before and there isn't a good way around it if you need to use tftp. I escaped my troubles by borrowing a Cisco 2650 that had newer boot roms and using it to load the flash for my impaired 2621. If you've got the router on contract Cisco will send you new boot roms - I've got to believe if I figured this out many other people have already reported the bug - but if you have no contract you need to pay for one (about $360 US for a 26xx) or borrow a newer router to load the flash.

Free Layer 3 Catalyst Lab (Kitty++) [7:6066]

This obvious truth being stated, we'll move on to the details of our latest 'event' :-) Using reverse telnet to 24.3.233.101 with a userid and password of 'ebay' you will find the following toys port 2008Catalyst 5000 /w WS-X5530-E2 NFFC supervisor 3 engine port 2007Cisco 4500 /w fast ethernet (not yet functional, must be made to netboot due to small flash) port 2006Cisco 7206 /w fast ethernet port 2005 Cisco 2501 port 2004Cisco 2501 port 2003Cisco MC3810 port 2002Cat 2912-XL-EN (due in Tuesday) For the moment all of these devices have no passwords beyond the userid ebay/password ebay needed to get past the terminal server HOWEVER the last time I provided a free online lab some buttnozzle, against my explicit instructions, went around and put passwords on every device. I don't mind providing this stuff when its around but this kind of behavior drives me to distraction so there is now a new policy: This stuff will be freely available over the long Memorial Day weekend and you can email myself ([EMAIL PROTECTED]) or Peter Slow ([EMAIL PROTECTED]) and we'll patch up anything that goes wrong. Once the weekend is over we're going to lock it down for our personal use HOWEVER we will accept small cash bribes ($10?) via paypal for a day of dedicated access. I think this will keep the lab available, still darned close to free, and save Pete and I a lot of tech support headaches. We owe massive props to: Peter Slow - the world's youngest AND shortest CCNP (17, 5' nothing) - for the loan of the Catalyst and supervisor engine Optimum Data - for the loan of the PA-FE-TX, the WS-X5224 in the Catalyst, and the entire 4500 /w fast ethernet. Dan Jaffe - for the loan of the Cat 2912 You can reach Optimum Data @ 800-879-8795 and I counted maybe 80 - 100 25xx series routers in their warehouse when I was in there a week ago.

Re: Why use GRE Tunnels [7:6155]
I have this configuration in production: branch office lan cisco 2611 Cisco 7206 running BGP Cisco 2611 branch office lan I have a /24 from one of my three BGP peers which is used for most everything in my network and there is a sloppy deploy of RFC1918 private addresses on two branch office segments. I knew I didn't want the 10.x.x.x/8 addresses leaking into my overall routing table and providing access from our colo sites into our corporate network. Our network is a star topology with the 7206 as its core so I could have done some fancy route filtering so only the three routers involved would see the private numbers OR used the VPN capability of the 2611s but I decided not to because: 1. complexity - there are two junior level people who work on our internetwork when I am not around - I judged the GRE tunnel to be much simpler to understand than some route filtering scheme 2. complexity - an IPsec VPN would have accomplished the same thing as the simple GRE tunnel but would have left the junior router gods scratching their heads if it had trouble while I was gone, to say nothing of the encryption tax on the link - there are some activities that light up the T1 for quite a while and a stand alone 26xx processor can't handle a full DS1 worth of encrypted traffic. 3. ease of maintenance - the GRE tunnels are tied to the loopback address on each router and we're running OSPF as our IGP. I make it a habit to tie VoIP, GRE tunnels, etc to the logical loopback - we did have a dual T1 configuration at one branch office for a while and it was nice to be able to change things and not worry about making sure the tunnel stuff was OK - it just automagically came right back in the event of a topology change (yes, I did the HSRP labs on a live network. So shoot me :-)) I've found many other uses for GRE tunnels ever since I discovered them - its so convenient if you're off site and want to do some work - rather than jacking up your access lists you just 'pipe' a little bit of your private address space to where ever you're at and you're working like you're in the office - think telecommuting in this case - pretty easy to move a little bit of 10.x.x.x/8 to my house and work from home when I needed. Yes, its somewhat insecure in that an @home guy could see stuff by snooping the GRE, but it would be darned hard to exploit unless he hijacked my public IPs at home.

CCIP certification - who else is doing it? [7:26605]
After completing my CCNP and CCDP about a year ago I pretty much dropped out of the education scene, sold all of my routers, and got busy with various radio related stuff. Last spring I started a wireless ISP with a couple of other guys. We got it funded about two months ago and I found that I was doing a lot more with Cisco, at least BGP/OSPF/802.1Q/QoS, and I started looking over the certs to see if there was one that mostly matched what I am doing work wise - the CCIP fits me the way the CCIE, with all of its enterprise stuff, never will. I've started slowly rebuilding the lab - a 2621 with voice and ISDN, my trusty old no serial number CiscoPro 2511 that I couldn't bear to sell, a Cat 1924 EN, and a 7204 with four sync serial ports dropped into my lap a couple of weeks ago. I figure I'll be back to 'full strength' before too long - I'll probably sell the 7204 and get something smaller/quieter. I don't see any "Pass the CCIP" books or any CCIP specific tests on boson.com so I started digging into the requirements to see if the CCNP/CCDP stuff might fit. This is what I've found so far: Building Scalable Cisco Internetworks (exam 640-900) is the larger of the two core exams and it appears to be very similar to BSCN with much added from BGP and IS-IS. I'm reading Internet Routing Architectures again and its a lot more fun this time - I have a dual T1 CEF bundle from Sprint, another T1 that terminates at a different Sprint router, and a UUNet T1 that ought to be up in a few weeks - nothing like real world application to get you to open up the book :-) The Multicast + QoS beta exam (exam 641-905) looks like much of the multicasting information from the BCMSN exam and a lot of QoS stuff that isn't covered anywhere else. I'm lucky here, too, lots of QoS stuff I need to do on my growing network. I've had the Cisco Press IOS 12.0 Quality of Service reference book for a while, and I just got Enhanced IP Services for Cisco Networks and the new IP Quality of Service book as well. Hopefully reading this stuff will fill in the blanks ... I looked at the five possible electives - Cable, Content Networking, METRO (optical), Security, and MPLS - MPLS is the only one that doesn't look completely useless for a network of the size I operate. I've been hoping they'll add a wireless specialization which would be very easy for me after the last six months, but MPLS looks like a good second choice - stuff I might be able to use, lab gear is not a fortune, and there are a couple of books out. I bought MPLS and VPN Architectures today. Has anyone on here completed the CCIP yet? Who is actively working on it?

did I find a BGP bug?
I am running a 7206VXR for our main BGP box. We're colocated with Level 3 (AS3356) and we have ethernet to them. We have T1s to UUNet (AS701) and Teleglobe (AS6453). I am running OSPF for my IGP and everything seems to be working well there. I have a 7120 in my office that I am using for BGP experiments. Besides what I show below it has a static route 0.0.0.0/0 to the outside world. When I run this config on the 7120 without the filter-list 2 I get a full BGP table viewable via 'show ip bgp' and the routing table gets populated with a bunch of BGP routes. When I turn on that filter-list and do a clear ip bgp from the 7206 and the 7120 I see the message counter going up on the 7120 in 'show ip bgp neighbor' but the BGP table never has anything in it. I chose to filter 3356 since the majority of the entries in the BGP table on the 7206 come from there. It was my plan to trim the BGP entries coming to an internal router down to the point where I could use something smaller/slower (like a 2611 with 64 meg) for BGP experiments and put the 7120 back to work. The 7120 is a bit warped, however, take a look at this evil 'show ver' ROM: System Bootstrap, Version 12.0(5r)XE, RELEASE SOFTWARE (fc1) BOOTFLASH: EGR Software (C7100-P-M), Experimental Version 12.0(2110:181554) [otroan-thanksgiving-rel 196] This is an IPv6 image based on 12.0. This isn't available on the web site yet - I had to display some pretty solid groveling technique to get it and it works fine for IPv6 stuff but its not so nice for IPv4. Is this config valid?

Re: bridging analog phone service with Cisco VoIP
The voice over IP depends on the IP portion of the network working - just set up the routers as you normally would and the voice traffic will travel just fine. You do have a potential problem with congestion here, don't you? I am assuming more than one type of data is using the area of the network that has the 4500s in it. This will be a good chance to exercise your cisco skills? Will IP precedence on the 1750s do the job? Do you have to set up the 4500s to handle precedence as well? Perhaps its a job for customer/priority queueing?? You'll have a wonderful learning experience with this ...

Re: Can two High density Serial ports be tied together? - YES!
Someone wrote to say that you use a null HSSI which is absolutely correct. I'd like to add that the timing setup is tricky - if you just set clock rate you'll see CDP making it from the DCE to the DTE device but you won't be able to establish two way communications. There is also a 'hssi dce' or something like that which must be set. Not all Cisco HSSI ports are the same. I've had an easy time getting this to work with a PA-H or PA-2H and a not so easy time getting it to go with a CX-HIP. rtc wrote: > A HSSI high density serial port is 50 pins and the size of a normal PC > serial connector. > We need a cale that goes [50pinHSSI high density serial port]--- [50pinHSSI > high density serial port] > > Its the only we can tie our 7513 to our other 3 routers because we cant > afford more Ethernet Boards. > > ___ > UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html > FAQ, list archives, and subscription info: http://www.groupstudy.com > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: CCIE All-in-one (author: moron or genious?)
It would appear that your contact with the book has so befuddled you that you've forgotten what a paragraph is. You're right that there are some problems with the CCIE Lab Study Guide but its a wonderful tool to have, all in all. I imagine the second version, which I see is out on the shelves at Borders, goes a long way towards correcting the deficiencies. I've used the book, errors and all, and I completed 70+ labs before I went off and started inventing my own stuff.

LAT - what unix terminal package to use?
This is somewhat off topic ... I am boning up for BCRAN in a week or two and I am reading the stuff about protocol translation. For those who aren't this far yet protocol translation is used for allowing telnet, x25, and lat sessions to interoperate - LAT is nonrouteable so its handy to be able to tunnel it over TCP/IP. Rather than some boring reading I'd rather just hack on this a bit and maybe get it running in my lab but I can't find a good linux LAT client. Does anyone have a suggestion for what package to use? I do have some FreeBSD boxes available at work as well but I am less familiar with them. Thanks in advance. As an aside, I am relatively old for this certification crowd, I attended a university that had a tight relationship with DEC, and VAX 11/780 S/N 2 (!) lived in my garage for a while as I parted it out after Iowa State decommissioned it. I've never used LAT, I've never run a protocol analyzer on a network with LAT, and I've never talked to anyone that has used it. Does this stuff still exist in production anywhere in the world? And more importantly does it ever turn up in any Cisco exam other than one question on this BCRAN pretest? -- "Just do the steps that you've been shown by everyone you've ever known until the dance becomes your very own" - Jackson Browne ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
VoIP - real bandwidth used for G729R8 codec
I have been tinkering with a 2611 and a 2621 with voice gear and I am tearing my hair out. I see the claimed bandwidth is 8k plus 'overhead' which the Cisco documentation seems to not want to cover in detail ... apparently the overhead can be double the size of the data for a total of 24k/conversation using Cisco's best codec. I've been messing with various low bandwidth configurations and I can get a solid conversastion through a 28.8 link. If I use header compression and compress the link itself it'll run through a 14.4k link. I need to do this for two AS5300s fully configured with 120 voice ports in each I understand what RTP header compression does but I can't use it because there are multiple hops involved and not everything is serial links. Can anyone point me to some useable information about tuning this stuff? Cisco's site and Google have proven pretty useless on this topic ... I get the feeling they don't want to talk about it. -- "Just do the steps that you've been shown by everyone you've ever known until the dance becomes your very own" - Jackson Browne ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: MAC Address support for c1900 series
The little switches have a limited MAC address table. If you know you have a link where they're going to see more MACs than they can hold you set it to be a 'network' port and the switch doesn't learn MACs from there. This is meant for a large campus environment where you have a 19xx serving a workgroup. I've worked on some real cluster (*#&$%s over the years and I've never seen a real world situation where this would be needed. I'd like to hear from anyone else if they've been in some shop of horrors where this configuration was required.

ipv6 tunnels available, leads to all sorts of fun stuff
I've colocated a Cisco 7120 at pensat.com and I am working with an engineer there to get ipv6 tunnels working. I've got half a dozen set up but we need to hit 40+ before they qualify for the next size block of IPv6 numbers. IPv6 is interesting but there are some other goodies that come with this connection as well. We've got the 7120 set up with enough ram to do BGP and we'll be turning that on shortly. I've got a 7505 with enough guts to do that job as well and I am planning on using it to give people hands on in something like a production BGP environment. I think the 7120 will be accessible but only in login and not enable mode. I am also in the process of installing an ISDN dial lab at work that will be accessible only via IPv6. Its got an AS5200, an Adtran TSu 600 for analog calls, an Atlas 800 to do ISDN switching, and some Cisco 1003s as clients. This should be ready within the next month or so. The initial config is not very difficult - you just need a CCO login so you can get the IPv6 software for your router or I can set you up with the 7120 image if that is your platform - its not released for beta yet but a kind Cisco developer 'loaned' me a copy. Once you have your software this is about all you need to get started. ! this is really all that is required besides the single default ipv6 route interface Tunnel95 description ipv6 link to Optimum Data Switching Lab 3ffe:b00:4007:5/64 no ip address no ip directed-broadcast ipv6 enable ipv6 address 3FFE:B00:4007:C12::6/127 tunnel source 209.58.21.221 tunnel destination 24.3.235.22 tunnel mode ipv6ip If this is something you are interested in please email me at [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

can anyone help with VoIP config?
I have two VoIP capable routers I've been messing with and I am tearing my hair out. We've made VoIP calls and thats no big deal but we're having trouble with the dial plan - what I want to accomplish is this 402-391-2413 <-> Cisco 1750 /w FXO card <-- IP connection --> Cisco 1750 /w FXS <-> plain ol' phone when a call comes to the PSTN number it should just ring the remote phone and when the remote phone is picked up the user should get the dial tone from 402-391-241. I've looked at dial plan stuff until my eyes cross and I can't figure this out - if anyone has an example config of how to do this I'd be eternally thankful. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Aironet Access points Range [7:23758]
The AP350 is a 100 milliwatts or +20dBm. The 'duck' antenna that ships with the unit has 2.2dBi of gain. The dBi rating indicates gain over an isotropic radiator - a theoretical perfect point radiator in free space. The 2.2 dB of gain indicates that there is a little bit of focusing of the radiated energy towards the horizon when the antenna is mounted vertically. To figure out how far out you can get a signal you'd need to know the receive sensitivity of the client radio in use (-75dBm for 2 meg ... this is the only rule of thumb I carry in my head) and the receive gain of the client antenna. If you're talking to PCMCIA cards they're nasty - essentially no gain. You'd need to figure the loss to find out if the observed signal at the receiver is greater than the receive sensitivty. Examine this URL: http://www.qsl.net/n9zia/wireless/ There is a lot of information in here about 2.4 gig radio performance and in particular there are a lot of nice equations that show how to calculate link loss and all sorts of other stuff you need to know.

Re: 802.1q trunking [7:57772]
DON'T TRUST THE CODE ON THE 35XX SERIES SWITCHES. Sorry for yelling, but its that important. I've seen repeated situations like this: router switch 1 switch 2 With a daisy chained configuration like this I've seen multiple instances where a vlan that is done correctly on the router won't work on switch 2, even though all the links are set up for trunking. I've tried forcing this situation with allowed vlan configs and so forth, and its just a pain in the you-know-what. It seems less of a hassle with the most recent code, but I never go in and offer a design like that - its just way, way too risky.

Re: Any VoIP compatibility issues between MC38010 & 1750? [7:49968]
I've used 1750 to talk to AS5300, 26xx to talk to AS5300, 26xx to talk to 72xx /w PA-VXC-2TE1, MC3810 to talk to 72xx, etc, etc. The thing to watch is the codec support on the image you're running - 711 is always there, 723 is next most likely, variations of 729 can appear and give you trouble. You can use 'debug voip ccapi inout' but I've never cared for the results - very, very verbose output.

a thing of beauty (12.2T BGP chaos) [7:50531]
I am getting nipped by this today, and its more than just VPN that is affected. Latest 12.2.8T5, too :-( CSCdw84776 When a customer edge (CE) router advertises a route that contains the provider edge (PE)-CE link, the PE router fails to install this route to the virtual private network routing/forwarding instance (VRF) because the route is already registered in the VRF as a connected route. If the connected route is learned from the redistribution of connected routes to the Border Gateway Protocol (BGP) through the external Border Gateway Protocol (eBGP), the BGP on the PE router marks the route with Routing Information Base (RIB) failure and prevents the route from being advertised to other peer internal Border Gateway Protocol (iBGP) PE routers. This behavior causes a loss of connectivity from the local connected route to the remote sites. Workaround: Source the route on the PE router. Do not allow the CE router to advertise the route that connects the PE and the CE routers. This condition does not occur if eBGP is not configured between the CE and PE routers and if a routing protocol such as the VRF, Interior Gateway Protocol (IGP), Open Shortest Path First (OSPF), or Routing Information Protocol (RIP) is used. -- Neal Rauhauser CCNP, CCDP voice: 402-301-9555 mailto:[EMAIL PROTECTED] fcc : k0bsd "This is my private email devoted to various mailing lists.

BGP: RIB-failure [7:50593]
What is the RIB-failure listed as a Status below? This was taken from a router that runs one EBGP and two IBGP sessions. Some of the internal routes come from two IBGP peers. The IBGP peers are pretty near identical in config, each presenting a single /24, one makes it, the other fails. By failure I mean the route shows up with a leading 'r' and it doesn't get presented to the EBGP peer, thusly the block doesn't make it to global BGP table. I'd be perfectly happy if someone could define RIB-failure for me ... cisco.com is strangely quiet on the topic.

Re: Pix logging to a Freebsd syslog server [7:51124]
The Cisco logging facility on a router uses a random high port as the source for the syslog packets. I assume the PIX is the same since you're having trouble. The FreeBSD syslogd expects the packets to be sourced from port 514. You can try the flag that supposedly allows syslogd to take random source ports, but it doesn't work :-( I'd strongly suggest you do what I did - just modify the syslogd source so it doesn't check source port, compile it, then install. If that is beyond your C programming skills drop me a note and I can email you the bungholed syslogd.c file and you can take it from there.

If you're not worried about speed you can use a rollover RJ45 and connect AUX ports and run PPP ... but there are no aux on 16xx.

Re: IPsec - what is wrong with this config? [7:52865]
Since I want the crypto to flow over a tunnel that is where I placed the crypto maps. I realize that Fa0 on these two machines is the same subnet, but it won't be when I place one of them in Omaha and the other in Houston - hence the tunnel structure. I found the IPsec stuff in the Hutnik & Satterlee CCIE Lab Study Guide(cool book!) after I learned to do it the hard way - my config appears correct but doesn't work. I removed the startup-config and I'm going to go at it from scratch later today.

Re: Cisco Serials and Theft [7:53574]
Let me firmly advise you against talking to Cisco about stolen equipment. There is a huge theft ring operating in the Bay area right now - mostly they defraud honest broker/dealers with dumpster grade gear but they have previously been involved in a variety of corruption - drugs for hot equipment from janitorial staff, cash under the table to Cisco employees at the Brennan(sp?) facility, faulty unserialized gear leaking from destruction facilties, and big time freight theft - 53' trailers & associated semis just vanishing from Cisco storage lots. There was a $5 * MEG freight theft from Netro last year which led to the breakup of the Roohparvar brothers money laundering operation in San Jose and a variety of other scumbags going on extended state sponsored vacations. I see the names Buompenserio, Bochinni, etc on the detailed criminal complaint in connection with the Netro freight theft and freight capers are usually mafia territory ... I advise you to *not* talk to Cisco because I made this mistake in 1999 after purchashing a piece of equipment from one of the little weasels out there. I called the FBI on them after a $9700 loss but I contacted the authorities three days after they'd nabbed the guy responsible for one of the semi thefts. I knew I wasn't getting my money back but I'd hoped to at least see the perp punished - instead I got implicated in their shenanigans. If your source isn't in the Bay area itself, and the prices are near what is being charged on ebay, and you know they guy, you're probably OK. If you want to talk in private that is cool also - I'll share names of known losers you should avoid :-) John Wright wrote: > > Hi guys, > > Just found this group and it looks like a great resource for Cisco > certification misc. questions.

would you attend a two day basics class? [7:54631]
Would you guys attend a two day, hands on basics class for Cisco routers? I own an internet provider and starting tomorrow morning I am teaching a two day class for our installers and one enterprise customer. Topics covered would be more productivity focused than theory - ie these are the top ten things you'll have to do on basic installs and we're going to touch each one from the customer and provider side so you guys understand what you're doing. This first thing kind of sprung up under my feet due to the enterprise customer wanting to get comfortable with their new four location VPN and the rest are tagging along - I am wondering if this is something I could put a little polish to and then offer to the masses. We're charging the attendees $500 for the two days - do you guys think something like this would fly as a regular offering via a community college, local computer store, etc??? -- Neal Rauhauser CCNP, CCDP voice: 402-301-9555 mailto:[EMAIL PROTECTED] fcc : k0bsd "I've seen the angels wearing their disguise, ordinary people leading ordinary lives" - Tracy Chapman Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=54631&t=54631 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: CCNP Help [7:54623]
Get the Caslow CCIE book and the Hutnik & Satterlee CCIE Lab Study Guide (119 hands on labs) as a minimum. The McGraw Hill Cisco Access Lists Field Guide is pretty good, you need the official Cisco Press BCMSN book for switching, the BCRAN book has some fluff but it does parallel the exam pretty closely. I used the http://www.boson.com exams for prep and I found them to be dead on for all four exams. To handle 75% of the Hutnik & Satterlee labs you'll need a router with four serial ports to serve as a frame relay switch, two other routers with at least one serial port, and some sort of ISDN access. If you can roll the fourth router I think it covers all the lab bases. ISDN is the big trick for CCNP if you don't have hands on with it - try and get a single line for home and share the spids between two 2503s using an NT1 - much cheaper to pay six months of ISDN service than to find a teltone or adtran box for ISDN emulation.

Re: NM-1CT1 or WIC-1DSU-T1 [7:74741]
The WIC-1DSU-T1 is a service module - it always appear as serial0/0 or whatever, and if you do anything with timeslots you are just adjusting the number used for this one serial interface. The NM-1CT1 is a channelized T1 interface. You must configure one or more channels in a channel group, then they get assigned to a virtual serial interface. In the bad old days before frame relay people used to get 56k leased lines for remote offices and aggregate them all by having a channelized T1 delivered with each DS0 being a separate circuit to a remote. One additional use for the channelized interfaces that I am aware of is attachment to digital modem modules like the NM-xxDM. There may be others, but that is the one that comes to mind first. If you don't know why you might want an NM-1CT1, you need a WIC-1DSU-T1 :-) neil K wrote: > > Can somebody explain when I can use WIC-1DSU-T1 over NM-1CT1 or what exactly > are the difference except that WIC-1DSU-T1 has a built-in DSU/CSU where as > NM-1CT1 is a T1 Module. > > Thanks in advance. > > neil > **Please support GroupStudy by purchasing from the GroupStudy Store: > http://shop.groupstudy.com > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html -- mailto:[EMAIL PROTECTED] phone:402-301-9555 "After all that I've been through, you're the only one who matters, you never left me in the dark here on my own" - Widespread Panic Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=74750&t=74741 -- **Please support GroupStudy by purchasing from the GroupStudy Store: http://shop.groupstudy.com FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html
3640 Router E3 support (maybe) [7:74800]
You can install an NM-HSSI and an external E3 CSU/DSU or use an internal NM-1TE3 to terminate a clear channel link. Cisco also built an NM-1A-E3 ATM card as well. In the US the DS3 counterpart to this card was typically used for DSL providers, while the clear channel card or HSSI + external CSU/DSU was used for internet connectivity. So the machine can physically terminate the link and it can stand a full circuit worth of traffic, but if you're considering running BGP *BE CAREFUL*. A little while ago I was working on a 128 meg Cisco 7206 connected to Sprint via a DS3. IOS grabbed 16 meg for packet buffer in the presence of the high speed interface and the 122k BGP routes from Sprint were too much for the remaining memory. A Cisco 2650 with 128 meg can still take full routes from Sprint because it has much less buffer space allocated, but in general I'm treating 128 meg boxes as ticking bombs if they're connected to Tier 1 providers - its just a matter of time - maybe this time next year - before they just stop working due to memory issues.

Re: backup interface [7:74836]
I think there are some implications with the ISDN interface being in backup mode - like IOS idling the interface. You could just use a floating static route to dodge that issue - works as long as you don't mind the ISDN not being tied to the serial interface and the effect should be the same - works whether you're looking for dial backup or you can leave ISDN up all the time. kaiser anwar wrote: > > Hi, >I am having issue with backup interface with isdn.

Re: PBR on 7200 subinterfaces [7:75055]
If you're trying to use the modular QoS CLI on subinterfaces its something of a mess - you have to create 'backpressure' at the physical interface level so bandwidth available is less than what your policy needs, or everything stays FIFO. I had a production network with this issue and I finally just gave up and pushed the QoS stuff out to the edge and crossed fingers on the core.

CCIP - who is doing this one? [7:45166]
I'm back to reading groupstudy after an eighteen month abscence. My CCNP/CCDP certs which I finished 12/2000 and 1/2001 are working wonders career wise, but I am doing a lot of carrier type stuff now and I've lined up projects that pretty much cover the BSCI, MCAST+QoS, and MPLS tests for CCIP - no reason not to get it done if I am going to do the reading anyway. I am curious to know the stats - how many people have completed this cert? I was about #1500 on CCDP and I'd like to think I'll be able to better that on the CCIP.

CCIP vs CCNP vs CCIE - not very close at all [7:45893]
I recently asked who was doing CCIP and got a raft of responses - "Its just like the CCNP", "Just got get your CCIE", "It doesn't make sense". Rather than continuing that thread I thought I'd highlight the differences and mention why the CCIP is more interesting than CCIE in many cases. The CCNP covers routing, switching, remote access, and troubleshooting. When completed, the cert holder is capable of entering IOS commands without having too many of them spelled out, and can identify the correct books to read to fill in his/her knowledge gaps. No disrespect intended - I've got it, its done wonders for my career, but the biggest effect I've seen is that it has let me accurately articulate just how much further I have to go. The CCIE is full of useless crap from the perspective of a service provider. DLSw+? I mean, do I care about this? And IPX? And Appletalk? If you're in a provider environment I *suppose* you could argue it might be of some use, but I bet I can make just as good an argument for getting your real estate license as a career booster. Now look at the CCIP. Nothing *but* routing as a fundamental requirement. If you read the other stuff you can see Cisco things this is for the big boys only - you'll be working 12xxx boxes and you don't care much about ISDN dial support. Where are you going to get good MPLS information? Cisco Press has a book out, but CCIE != person who read and fully understood that book. I need to configure it, not just be able to define the acronym. And then there is multicast. Conceptually simple, fundamentally evil, and known to attract wing nuts with business plans based on it. I've got two wing nuts with their checkbooks cocked and locked right now - if they can't run a single 384k stream from their site and have it fan out to N+1 paying remotes I get to keep eating Ramen, instead of moving up to TV dinners. There are a lot of other very heavy things in the various CCIP tracks, I'm just touching on the ones that can be done with gear I can afford and appeal to my existing customer base.

CISCO KNOWS SQUAT (was any good linux BGP simulator [7:46088]) [7:46107]
This one is just too juicy to pass up :-) The concise question is "Why would you use linux/freebsd or an appliance based on them instead of purchasing a real router?" Cisco rules the backbone, they do enough on lan switching to get my vote their, and their Aironet radios are OK if you're abusing 802.11b by running it as a wireless internet provider but ... CISCO KNOWS SQUAT ABOUT ROUTER/WIRELESS INTEGRATION! There, I've said it. Detaled proof of concept is below: Lets consider a network I recently installed. I've got a tower on a building on a bluff that overlooks a valley where there is no DSL service. On the opposite side of the valley I have another tower on a building on a bluff. The two towers are separated by about three miles. Some sites in the valley can see one side, some can see the other, neither site would cover the whole valley properly. The building closest to my head end has an elevator shaft on top with my small tower bolted to the side. There is room for a good sized 19" cabinet and AC power. The building on the opposite side of the valley has a beautiful 50' tower on top but the only facilties on the roof are a NEMA outdoor enclosure. The NEMA enclosure can take a couple of radios and maybe a small hub but would not take any router larger than a 1605. So, this one building has a backhaul link, it has a customer cell, it feeds the cell across the valley, and I have two other customers attached to this location that received dedicated point to point links for a total of one cell and four point to point wireless links. There is also a wired link to our customers in the building. From the layer three perspective this location has four /29s used for point to point (why not /30s? you tell me, but ponder the wonder of VLANs and OSPF first :-] ), one /27 that is the customer cell, and a /29 for the wired customers. How would you build a network with six total subnets, one wireless cell, and four point to point links, using only Cisco equipment? This is the parts list with estimated pricing: Cisco 2620 $1500 Catalyst 1912 $300 Aironet AP352 $650 four x WGB352 $1800 total $4250 Now consider the alternative - a $400 PC, a $50 flash card, $200 for a linux based wireless capable OS from http://www.mikrotik.com, two PCI Aironet cards ($350) and a Dlink quad port ethernet card ($100). $1100 total I still needed the $650 AP and one external $450 WGB352 - $1100 for this. So, for $2200 I got the effect of purchasing $4250 of refurbished Cisco gear. Now lets look at the soft benefits of MikroTik vs IOS: Feature MikroTikIOS ssh yeswith provider image OSPF yesyes PPTP server yesnot that I can find PPPoE server yesyes, clumsy rate shape PPPoE client bit rate per user nope, just IOS traffic controls NAT yesyes processorAMD 1 gig 40 MHz PPC memory 256 megmax out at 64 meg firewall ipchains(cool) clumsy access lists user interface killer CLI clumsy CLI annual support $500 or so including aironet about 3X MT costs Over a three year period the MikroTik box is going to cost me about one fourth of what I'd pay for a minimal Cisco solution and the performance of the MT is on par with a 7206 /w an NPE300. Now there are a lot of reasons to prefer Cisco in the backbone over MikroTik, but I'm not going to say anything :-) You'll just have to download the free eval of MikroTik and make it work with your Cisco lab if you want to know ... > I always see people asking for Linux/Unix sims for BGP > or just to simulate a router in General.

I've got a single Sprint T1 at one end of the network, an AT&T and UUNet T1 at the other end.

Aironet SNMP tricks revealed [7:48574]
I spent about twenty hours last week dorking around with AP35x and BR35x, MRTG, and snmpwalk on a unix box. I've created some MRTG configs that will graph common 802.11b errors vs good fragments and I posted the MIBs used along with links to two MIB browsers that will produce the OIDs you need to drive MRTG. The documentation is kinda crappy, the information is incomplete on CCO because of MIB compile problems with old Aironet enterprise MIBs, and its a real pain to figure out - but now you have no excuse, since I've done 95% of the hard work for you. I also started an Aironet SNMP specific mailing list at mailto:[EMAIL PROTECTED] You can see what has been done so far at http://aironet.wispair.net/ FYI this little dab that I put up is a good read if you want to get started doing stuff with MRTG besides the out of the box bandwidth management - I haven't bothered to extend it to other devices but one could dig around in the MIB directory on Cisco's site and create all sorts of cool monitoring tricks. -- = mailto:[EMAIL PROTECTED]phone: 402-301-9555 = Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=48574&t=48574 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
