RE: New Book for CIT [7:47009]
Having just written the new 606 exam today, I can tell you for a fact that the 506 book is still valid. But what is more important is the knowledge learned from doing the foundation (routing,remote access, switching), which helps with troubleshooting. I still don't see how one can troubleshoot if you don't have the theory bedded down well. This exam was tough for me. BSCI was easier in my opinion. Maybe it's because I never paid to much attention to this book and all the small print. I passed by about two questions I think, and the exams are still in the format of the old exams with a few changes of course. Based on the questions though, I can safely say ... don't take it lightly anymore. I had a guy who was writing CCNA next to me, and he didn't pass. I think those exams probably look like the one's they show on the cisco website. Well, now I start again with my CCNP books, this time to make notes after cross-referencing the CCIE level books.

serial interface down/down or up/down - answers & questions [7:47130]
John, All, Actually, both router interfaces(DCE or DTE) will show "down/down" if the both ports remain "administratively down".:-> Seriously, where I work since alot of our circuit are located in various locations within a number of our building we make use of what we call an Automatic Network Control Circuit (ANCC) system which logically maps our DCE devices from our Demarc to our NOC equipment area. Nonetheless, in answering Priscilla's question there is no one answer to the question. Basically, if the CSU/DSU is configured with a mismatch on the framing then the router port will come up/up. If the encoding is mismatched then this will cause the CSU/DSUs to lose "SYNC". Technically this will cause the router port to continually flap(up/down). When the CSU/DSU is configured correctly with the bandwidth(the configuration of the DSO slots(Nx64)) mismatch, this will allow the equipment to "SYNC" and the router ports will indicate up/up, however no data will traverse the link. John, is very correct in that the DTR on the DTE device has to be asserted for the DCE device and obviously for the DTE device to indicate an up/up. Howard, also brings up a good point in that framing and encoding does relate to layer one. Question? If encoding and framing are thought of as sub-layers of layer1, then what parallel can be drawn to other layered tecnologies that would allow/indicate an active interface without all the requirements being met. (i.e ISDN, ATM, and an IP interface) Chuck, I took your comments to heart and took down a number of of T1 customers to prove my noted few points.:-> I hope youre happy.

Re: serial interface down/down or up/down [7:47101]
Ok, I have a backup frame relay that I can test on. Here's my findings: I have an Excalibur ISX5311 connected to a 7206VXR. We have a full T to the frame using ESF framing. The line is up/up. I modified the framing to D4 (there appears to be no SF?), and checked the line. It went down/down. I was surprised. I expected up/down. It was showing DCD & DTS were down. I then put my framing back and changed the linecode. We use B8ZS, so I changed to AMI. The line then started flapping up/up to down/down. Again, when in down/down it was showing DCT & DTS down.

Re: serial interface down/down or up/down [7:47101]
I have found a good bit of conflicting information on the causes of down/down and up/down. All agree that down/down can be caused by: 1. no cable connection 2. CSU/DSU powered down Some other reasons, although not consistently referenced in the literature are: 1. Faulty cable (may also cause up/down) 2. csu/dsu failure (not specify hardware or software)(may also cause up/down) 3. router serial int hardware problem 4. a DCE router interface will be down/down if DTR is not raised by the DTE device There are a plethora of reasons for up/down Not sure this clarifies, but hope it helps some Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47136&t=47101 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Priscilla, Thanks for posting an interesting "case". I am planning on testing your scenarios hands-on during the weekend and post the results by Monday. You may have already seen it, but I'd suggest that you visit the following CCO URL for more information on the Serial Interface status you're trying to clarify. http://www.cisco.com/warp/public/112/chapter15.htm#showinter Hth, Angel MCSE, CCNP-R&S, CCNP-WAN -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Priscilla Oppenheimer Sent: Thursday, June 20, 2002 5:34 PM To: [EMAIL PROTECTED] Subject: serial interface down/down or up/down [7:47101] Hi Group Study, While writing some questions for a practice test, I found myself questioning what I thought was the right answer. Here's the scenario: A Cisco router serial interface is correctly connected with a good V.35 cable to the data port on the DSU side of a CSU/DSU. The CSU/DSU has been misconfigured for the framing method (SF instead of ESF). The framing doesn't match what the provider is using. (The question refers to a CSU/DSU that is external to the router, not one that is built into the router.) Will the Cisco router serial interface be down/down or up/down? And, would the answer be any different if the question has to do with misconfiguring the encoding (AMI versus B8ZS)? If you have real-world experience with this, that would help. I have read the Cisco documentation and the troubleshooting charts, etc. Thanks Priscilla Priscilla Oppenheimer http://www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47138&t=47101 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Our company purchased some load balancers, they seem to want to use NAT in every configuration. I don't think it's a great idea to run NAT on an intranet (which is what our app is going to be). Can anyone suggest a good load balancer that is good for running on an intranet? Maybe I should be looking at cisco. The device we are using is "Coytote Load Balancer", Do you think a web switch would be better? Seems this device is really for dual network design, not an intranet application. I guess I should be looking at cisco content switches?

Re: BGP Prefix List Question [7:47117]
I have developed a method. I draw a generic rule like this: lenge-value---le-value---32 For the command "ip prefix-list MYLIST permit prefix/24 ge 25" I put that values on the rule: len=24 ge=25 (values greater than 25 marked with *) le= not present 2425***32 So the command "ip prefix-list MYLIST permit prefix/24 ge 25" match the prefix length from 25 to 32. For the command "ip prefix-list MYLIST permit prefix/24 le 28" I put the values on the rule: len=24 ge= not present le= 28 (values lower than 28 marked with *) 24***2832 So the command "ip prefix-list MYLIST permit prefix/24 le 28" match the prefix length from 24 to 28. === Finally for the command "ip prefix-list MYLIST permit prefix/24 ge 25 le 28".

CCIE Beta results [7:47144]
I just called prometric and found out that I had failed the CCIE written beta test i took at the end of April. I recall some emails going around from people that couldn't believe when Prometric told them that they passed. I called at that time and they told me I had passed. I didn't believe it either. Call Prometric today and I think you'll find like I did that if it seems too good to be true it usally isn't. I'm just wondering if anybody was able to pass that test...

On a V.35 connection, this much I know is true: DTE is responsible for DTR and RTS DCE is responsible for Data Carrier Detect (CD), DSR, and CTS. Numerous things can go wrong to cause the DTE or DCE not to assert one or more of these. They have to all be asserted for the interfaces to be up/x. However, are all those things local to the V.35 endpoints and cabling? Or could a problem out the other end of the DCE (out the carrier side of the CSU/DSU) cause them not to be asserted?

t/r question: hex vs decimal involving 3920 & routers [7:47148]
i don't have a 3920 t/r switch on me, so i have to ask this question: is it accurate to say that 1. the bridge id & ring # under the t/r interface on a router is in DECIMAL? 2. the bridge id & ring # under the t/r interface on a router is in HEX? therefore, if u want to assign RING 100 to BRIDGE 10 on r1-to0 & RING 200 to BRIDGE 14 on r2-to0, u would use these exact numbers on the routers under the t/r interface... ...but on the 3920, u would configure the following (as practice, i just add 1 to the crf) for r1-to0 connected to the 3920: virtual bridge: vlan id:100 vlan name: brf100 bridge id: A virtual ring: vlan id:101 vlan name: crf101 ring #: 64 for r2-to0 connected to the 3920: virtual bridge: vlan id:200 vlan name: brf200 bridge id: E virtual ring: vlan id:201 vlan name: crf201 ring #: C8 Timur Mirza Principal Network Engineer Network Planning & Engineering, West Region 15505-B Sand Canyon Avenue Irvine, California 92618 Verizon Wireless 949.286.6623 (o) 949.697.7964 (c) Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47148&t=47148 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

admin distance question [7:47147]
Looking at the administrative distance values for the different routing mechanisms. Why would eBGP have a lower admin distance for a route than if learned via an IGP (like OSPF or ISIS)? Why wouldn't the default behavior be to prefer routes learned from the local IGP rather than via eBGP?

Re: serial interface down/down or up/down [7:47101]
I guess the question is too hard for a practice test if NOBODY can answer it!? Here's the thing: Cisco says that a down/down interface means the router interface is not sensing a Carrier Detect signal (that is, the CD is not active). Now, from my studies of V.35 I know that data carrier detect (DCD or CD) comes from the DCE side of the V.35 link, carried on pin 8, yadda, yadda. It comes from the data interface on the DSU side of the CSU/DSU. If the router is correctly connected to the CSU/DSU, will it see CD or does the answer depend on whether the CSU/DSU is also correctly talking to the telco? Does "carrier detect" mean literally what it sounds like it means? Would the CSU/DSU not assert CD if there was a problem on the telco side? And hence the router wouldn't see CD and would say the interface was down/down. Not something I can easily test. Maybe I better simplify the question. ;-) Priscilla At 06:34 PM 6/20/02, Priscilla Oppenheimer wrote: >Hi Group Study, > >While writing some questions for a practice test, I found myself >questioning what I thought was the right answer.

Re: serial interface down/down or up/down [7:47101]
The interface ends up being down/down if encoding and framing are misconfigured on the CSU/DSU? Sorry, you weren't clear about that part which is the part I'm desperately trying to confirm. ;-) Thanks.

Re: serial interface down/down or up/down [7:47101]
Thanks for the additional answer. Cisco says to check the cable, yes, but they don't go so far as to say that's the only time you would see down/down. They say the meaning is no CD. Well, when is there no CD? Of course there's no CD if the cable is bad. I think there are other situations where there's no CD also. Cisco also says that down/down could be a telco problem. See here: http://www.cisco.com/univercd/cc/td/doc/cisintwk/itg_v1/tr1915.htm#xtocid195572 This may be one of those things that will remain a mystery. I can reword the sentence to make sure the reader knows to check hardware when an interface is down/down. I would love to say more, but I don't think I better without confirmation.

Hello everybody. Firstly I just want to say that changing the search engine to google was a very good idea and secondly I think that a good way for supporting groupstudy would be to sell (at reasonable price) an annual CD-ROM with the archives, I wouldn't like to lose such important source of knowledge if something happens or if some day Paul doesn't want to continue with all that...and we could consult groupstudy off-line...

RE: serial interface down/down or up/down [7:47101]
And to add some more confusion - some CSU/DSUs (Larscom) use a EIA-530 cable. In Europe either X.21 or V.35 are used depending on country and (I think) speed.

RE: CCIE Beta results [7:47144]
I did call Prometric a while back, and yes, they did indicate a passing score, but then I asked the CCIE team to verify the validity of that information, and they clearly said that the results had not been fully analyzed, and that the pass/fail cut had not yet been determined. (That was about 2 weeks ago I think). So, if you called Prometric, did they really give you correct info, or are they just still making the mistake of giving out information that's not correct? I agree that this Beta was a bit tough, and that the current 350-001 is a walk in the park comparatively speaking. Good Luck!

Re: serial interface down/down or up/down [7:47101]
I've seen both down/down and up/down in real-world scenarios. The difference between the two seemed to be the intelligence of the CSU/DSU. With a recent Adtran unit, it goes down/down - if the CSU is down, it takes down the DSU. I did not delve into the configuration to see if this behavior could be changed. A very old Black Box unit that I've played with will happily keep the DSU up regardless of the state of the CSU. This one was configured with DIP switches, and I didn't see a way to change the behavior.

CIT 640-606 exam update [7:47160]
The CCNP CIT exam pool of questions was revised recently and the new exam number is 640-606, but the questions on the new exam are still multiple choice and there are a few drag and drop or pick and place if you prefer. This exam is no more difficult than the prior version in my opinion and it shouldn't give you much trouble once you've taken the three other CCNP exams. The exam details as of June 21, 2002 are 58 questions in 90 minutes and the passing score is 776 on a scale of 300-1000. I will be writing a complete article on my exam experience and my recommendations for tackling this one which will be available soon at www.TCPMag.com Good luck on your next exam!

RE: serial interface down/down or up/down [7:47101]
I have seen down/up on an Ethernet interface before. On the older code of PIX's (5.x) , interfaces were required to be connected even if they were shutdown for a failover config. This was for keepalive purposes... You would end up with an admin down/up, as it was shutdown, but still receiving keepalives... Talk about a condition to make you scratch your head...

RE: OSPF, when is it time for more than area 0 (try 2) [7:47165]
Here are some commands you can run, and their significance in determining whether your OSPF Area 0 routers are working too hard or not: #show ip ospf: Look for: "SPF algorithm executed xxx times" - I don't know what constitutes a high number, but if it's in the hundreds or thousands after a relatively short period of time, that means that instabilities in your network are causing the routers to frequently run the Dijkstra (SPF) algorithm, which is a very processor intensive process. #show processes cpu: Look for: "OSPF Hello" - Again, I'm not sure what "high" is, but one of our routers that has 1 Broadcast interface, and 13 Point-to-point interfaces holds steady at 0.06% processor utilization. Anyone care to chime in on what a high number for this process would be? "OSPF Router" - This is the one that will spike during SPF calculation, so watch the 5 minute utilization here, if you see it consistently high, that probably means it's time to move to multi-area OSPF #show processes memory | include OSPF: (the "| include OSPF" just helps minimize the junk) Look for: OSPF Hello & OSPF Router - Not real sure about OSPF Hello, but I believe the memory counter for OSPF router indicates the size of your databases. If you find these growing large enough to start running the router out of memory, it's time to move to multi-area OSPF (again, I don't know what size of network it would take to do this, sorry. Any takers on that one?) The number of SPF calculations and CPU utilization are the two big ones to watch our for (and are directly linked to one another) If you see lots of re-calc's and they are holding your processor hostage, then you should start thinking about redesign.

Hi Everyone, I am new to this group and I just passed my CCIE written and am looking forward to participating. I have done a lot of lease line installs the last couple of years, and I have worked with EIA-530, V.35, G.703, EIA-232 etc...Most of these installs required me to go through an additional pieces of equipment like a hardware encryption unit or an additional set of CSU/DSUs to extend the circuit while maintaining the carriers Demarc point. Anyway, I have been required to make numerous cables to make things talk. And during troubleshooting/testing with a breakout box I discovered that the only signal required to bring the serial port up was a high on DCD/CD with all other leads open.

I took the beta back on march 18 and failed (according to prometric anyway, I still dont have any official results and it isnt showing on the tracking system), so I took the 640-506 exam this week (booked before the change to -606). I found the beta exam I took in March, really difficult and had a feeling that I had failed when I left the test center. On the other hand I found the 640-506 exam that I took this week really simple. Admitedly it is possible that I somehow learnt a lot between march and this week, but I dont think I have learnt that much since then. There were a number of areas where I recall tough (for me at least) questions in the beta that I focussed on before this last test, but found that there just werent many questions about them in this test.

RE: Cable Modem DHCP problem [7:47175]
Randy- The assumption is that you had a PC hooked up to the cablemodem prior to the current expectation to use the router as the Ethernet host behind the cablemodem. Whether or not this is true or not doesn't really matter, but... ... in all of my experiences over the last 6 months, pretty much every cablemodem provider has their equipment set up in such a way that the first one or two MAC addresses that are connected to the cablemodem for Internet access are recorded in some MAC Database and paired with the "extended" DHCP lease you get. The only real way to clear these MAC entries from the DB is to call tech-support and tell them you are replacing the network card in your computer, and need to have the MAC table for your modem reset. It's is advisable to NOT tell them you are hooking up a router to it, as they will immediately "go stupid" and tell you they don't support such a scenario - like as if a router's Ethernet interface is any different than any other Ethernet interface! Once they have the MAC table reset, they most probably will remotely reset the cablemodem, or have you power cycle it. This will allow for the learning of the new MAC address to associate with your DHCP lease. This is most probably why you can't get on the net at the current time with your DHCP lease. Let us know if this fixes your problem! Good Luck!

I would like to release the lease recieved from the cable modem (comcast) . I have tried powercycling the modem, router, reload, shuting the interface ect and nothing works. I get the same lease all the time and cant get out to the internet. thanks Randy Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47182&t=47175 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
