Re: RE: 500-CS...HELP!! [7:2414]......here is my 500-CS config [7:2536]
**WARNING - THE VERBOSITY BIT IS SET - THIS MESSAGE IS DISCARD ELIGIBLE IF YOUR BUFFERS ARE FULL** Hi, I think there may be a degree of misunderstanding about the use of the no exec command. If you have seen this command used in an access server that provides dialin access to corporate users, or you have configured an access server for a typical ISP, that is probably an appropriate place for this command. When you place no exec under a given line, it will preclude any use of an executive process (user or privileged). Dont take my word on it. Lets all do a little test on our home routers. First, do not do this test in a production network, period. Second, it you are a little weak on the IOS, you may want to brush up on your password recovery procedures; you will need it later. Here goes. I will show you three different ways to test this. First, go to the console port of your router **DO NOT TELNET IN** Next, configure your router as follows: router# router(config)# router(config)#lin vty 0 4 router(config-line)#no exec router(config-line)#exit router(config)#int loopback 77 router(config-int)#ip add 1.0.0.1 255.0.0.0 router(config-int)#end router# Now attempt to telnet into your own router using any accepted telnet command, such as: router#telnet 1.0.0.1 or, router#connect 1.0.0.1 or, router#1.0.0.1 You should get the following output: 2503#telnet 1.0.0.1 Trying 1.0.0.1 ... Open [Connection to 1.0.0.1 closed by foreign host] The connection will not open. Since we did not have any access class commands applied, the only other explanation is that a vty line is dedicated for one purpose, namely to run an executive process. You can either telnet into the vty to do user exec commands, or privileged exec commands. When the line has been restricted so that no exec is in place, then the vty line is effectively shut down and no connection is allowed. Remove the "no exec" command under the vty lines and reattempt it. You will note it works. Lets try it a second way. This time, we will implement the following commands on any cisco router that has both an AUX port and a console line. We will change the AUX port into a line configuration and we will issue the no exec command on the AUX line. Before you start, make sure your configuration is clear under the AUX line and console lines. It should similar to this: line con 0 transport input all line aux 0 transport input all Go ahead and verify you get a command prompt in both AUX and console lines. Verify you have interactivity by starting a ping to 1.0.0.1 on each (physically plug into both ports). Then execute the following additional commands while plugged into the AUX line: router#conf t router(config)#lin aux 0 router(config-line)#no exec router(config-line)#end router# Try a ping again. It will work. Now save your configuration with the following command and execute a reload while still plugged into the AUX line: router#copy run start router#reload Proceed with reload? [confirm]y 07:35:36: %SYS-5-RELOAD: Reload requested The last line is the last entry you will see. When the router reboots, you will not be able to see any output. You may be asking yourself why the command did not take place immediately as most commands do. It did take place immediately however, you were still on a connected line. Once the connection is severed (via a reload), then the AUX line will have no exec process when the system reboots. This can be further verified once the system boots by attempting to get a router prompt from the AUX line. When you are unsuccessful, plug into the console line and go into line configuration mode and restore the exec process with the following commands: router#conf t router(config)#lin aux 0 router(config-line)#exec router(config-line)#end router# Log back into the AUX line and verify it now works properly. On some routers you may have to reboot to get this to take effect. The final check on this is to do the same test with the console line. WARNING - DO NOT ATTEMPT TO DO THIS UNLESS YOU ARE VERY FAMILIAR WITH PASSWORD RECOVERY!!! Plug into the console line and type the following: router#conf t router(config)#lin con 0 router(config-line)#no exec router(config-line)#end router# Run the same test and verify all functionality is still there, e.g. execute a ping and get a response. Everything should work just fine. Save your config and do a reload as before: router#copy run start router#reload Proceed with reload? [confirm]y 07:35:36: %SYS-5-RELOAD: Reload requested This time you are going to notice something really strange and different. You will note that you can watch the router reload and go through its POST and execute its startup-config. The only problem is that you cannot tell the router to do anything because you guessed it, you have no exec on the console line. You will see output go by one the screen, but you cannot

VLAN's and Routers [7:2534]
Still struggling with VLAN's and a basic question escapes me. If I create: VLAN1 as 10.200.1.x/16 VLAN2 as 10.200.2.x/16 or /24 I get "VLAN's overlap", which I assume is a bad thing (at least at my skill level, I understand you could use overlapped VLAN's). So, I'm confused how I can assign scopes to each VLAN, what the exact rules are. I'm starting to come to the conclusion I cannot use VLAN's without a router. Is that a correct assumption? Any help, tips, leads appreciated.

Re: IRB and CRB [7:2476]
CRB is less used today since switches can do the job very well.
IRB is more commonly used. At least some of the IXes is using this
ISPs connect to IX using ATM VC but not willing to put router there.
As a result, the connection to IX end is an ATM sub-Interface. Since
the IX is doing L2 job to switch Ethernet traffic between ISPs (of
course, doing BGP route exchange), the ATM subinterface should be
bridged to the L2 Ethernet switch to do traffic exchange... and
therefore they deploy IRB.
I don't have bad feeling about IRB (neither good feeling). It should
work. However, I encountered lot of silly troubles on lot of IOS
implementations such as:
1. 50% packet discard (not due to the load. It just happened normally)
from FE to ATM BVI. (12.0.7T)
2. After reconfig other ATM VC, the whole PA-A3 is down and require
reload. Even at 12.0.10GD on a 7507.
3. I need to place my PA-A3 to a ealier firmware version in order to
make it work probably.
4. Due to STP, I cannot really do multipath load balancing (old
bridged network problem).
In most case, I think IRB should be avoided. This is my 0.02.

Re: retransmission of packets in WAN [7:2525]
Kuldip, For most of these, a quick look at the purpose of the protocol will answer your question. However, don't assume that error control is required, sometimes there isn't any error control at all. However, even when a protocol has error control functionality, don't assume that it will do anything beyond discarding corrupted packets/frames. A good way to check if a protocol does some form of error control is to look at the header or frame format. If a CRC or FCS is included then it does at least minimal error control (as in the case of SDLC). A closer look at how the protocol operates is needed to determine what sort of error control is performed. a. X.25 --> Guarantees data integrity by using HDLC to handle error control. X.25 itself handles the call setup/teardown procedure, not error control (uses the following packet types: Call Accept, Call Request, Clear Confirmation, Clear Request, Data Packet, Diagnostic, Interrupt Confirmation, Interrupt Request, Reject, Reset Confirmation, Reset Request, Receive Not Ready, Receive Ready, Restart Confirmation, Restart Request, Registration Request, Registration Confirmation). b. HDLC --> The job of HDLC is to ensure that data passed up to the next layer has been received exactly as transmitted (i.e error free, without loss and in the correct order). c. SDLC --> Less error control than HDLC in that it only provides link integrity. Frames received correctly are acknowledged by the receiver while erroneous frames are ignored. d. Frame-relay --> There is no guarantee of data integrity at all. Error control is sacrificed in the interest of speed. Its assumed that higher layer protocols will handle all necessary error control. The network delivers frames, whether the CRC check matches or not. It does not even necessarily deliver all frames, discarding frames whenever there is network congestion. e. DLSw+ --> Error control is provided by SNA, not DLSw. DLSw only handles link control. Most bridging protocols (as far as I know anyway) deal strictly with getting the data from point A to point B and let the layer 3/4 protocols handle error control/correction. f. ATM --> ATM does not have error control functionality (think about what goes into an ATM cell - and what doesn't). Any error control has to be performed by the protocols that are encapsulated in the ATM cells. g. T1, E1 --> These are layer 1 protocols. T1 and E1 deals with signaling and encoding. At this level, its just bits, not frames or packets. Error control is generally handled at layers 2 through 4 (when its done at all). Hope this helps, Karen *** REPLY SEPARATOR *** On 4/30/2001 at 12:28 AM Kuldip Singh wrote: >Hi, > >Can someone help me find out who (router or host) will >retransmit the packets if they were lost in the cloud >while using: >a.

Random Randomness [7:2530]
This seems a good one for someone to sink their teeth into. Any takers? OK, here's the problem: Our Engineers are working on a drives application that uses Cisco Switches. I've attached a .tif file that contains 3 pages - a System Diagram, a Logical Diagram and a diagram showing some troubleshooting steps they've done. System Diagram: They've got a PLC with two 10BT copper ethernet cards in it. One card does 10BT half-duplex TX data flow of 1700 UDP Frames per second. The other does RX same type & rate. (There are no collisions.) These are plugged into one of two Cisco 2900 XL fiber switches (the 2 switches are connected via 100FX) through a copper expansion card. The 2 2900XLs are connected via 100FX (autoneg, I believe, for full/half dup) to 17 Digital Drives. Each of the 100FX lines to the drives has data flow of 100 UDP Frames per second for both TX & RX. Logical Diagram: Logically, the PLC talks to each Drive at 100 UDP Frames per second. There's a Protection Timer on each Drive that tracks the max time between UDPs Received. Typical time = 10 milliseconds. Worst case = 30 millisecs. Fail = 1 second +/- 10 milliseconds. Problem: On 1-2 drives randomly every 24 hours we see a loss of PLC to Drive UDP Frames for *exactly* 1 second +/- 10 milliseconds BUT *no* loss of Drive to PLC UDP Frames. Troubleshooting steps thus far: 1. Each drive has 2 LEDs, one for TX Activity and one for RX Activity. They connected the LEDs (or maybe the thing that lights the LEDs?) to a Recorder to monitor the TX & RX. They saw a loss of RX Activity for 1 second and *no* loss of TX Activity. 2. Via diagnostic configuration of the switch, they took Drives #1-4 and sent the Frames they were sending to a Sniffer (which was using custom software that the Engineer in charge wrote). This test was unsuccessful because *even though it's a switch & not a hub* they didn't get data unique to Drives #1-4, but ocassionally got stuff from the other Drives, too. This really stumped them because a switch is not shared media, but switched (duh) & they don't think that they should see anything other than traffic to/from Drives 1-4 since they're each on their own port. Next Troubleshooting steps: 1. Set the Switch to Drive 100FX runs to Full Duplex only 2. Put a 10BT hub between the Switch and the PLC & sniff to see what traffic is happening there. Questions: 1. Why were they seeing stuff from other ports when they did Troubleshooting step #2? 2. Is this a known issue with these switches? It's intermittent in that it doesn't happen with any seeming regularity to any one port, but happens to each port at random intervals. Some ports never do it. Some do it more often than others. Haven't seen any pattern to it. Caveat: They have NOT ruled out the possibility that it's a problem with the PLC. Next Troubleshooting Step #2 is designed to determine if the error is in the switch or the PLC. ie. is the PLC sending the data or is *it* stopping for 1 sec randomly - maybe due to buffer overrun? Any help that anyone can provide - whether it be additional troubleshooting steps or KB articles for the Cisco switches etc. - would be greatly appreciated!

Re: IS-IS: Default route for L1 router [7:2485]
The adjancencies are formed, here clns routing is automatically enabled when you enter routing isis, but actually clns routing is not enabled at any interface, so it will not try to build clns routing table. According to Doyle's book, you need to do something to let L1 knows the default route, for example, have clns routing command *on* interface level.

Re: is it possible to mix and match flash cards? [7:2518]
There are a few places where you can mix flash but mostly you have to do it by trial and error. 7200 and 6500 flash cards are totally interoperable. Sometimes you can use a flash card from a different platform and reformat in the target platform and sometimes it works, sometimes it doesn't. Flash SIMs are another story. I have gotten 3600 flash sims to work in a 2600 but only after a reformat. 2500 and AS5200 flash SIMs are the same. There are basicly 3 types of flash systems in Cisco routers: A, B, and C. If you look on the Doc CD under: IOS configuration, configuration fundamentals, File system commands, you will find all the differences and some platform interoperabliity.

Re: Question .. CCIE lab and scheduling! [7:2461]
Guess it's nice to be called "stupid" by someone who asked for advises. Teach all of us not to response in future to stupid questions in the first place. Why did you bother to take the written in the first place, why not be prepared for the lab and then take the written ? Sure as hell save all your headaches !! Between waiting 6 months and doing the lab at the nearest possible time, I'm sure there are enough people "smart enough" to tell you that it might just be worth it.

Re: IS-IS: Default route for L1 router [7:2485]
I'm not convinced that you have L1-L2 adjancencies as you think - you have a fairly random mix of circuit-types on the interfaces and is-types on the isis processes. Might want to do a "sh clns neighbors" on each router to see that the adjancencies are as you think they are. Don't recall quite how default/unspecified circuit-types will behave, but prolly worth checking Also, you *do* have clns routing enabled on all the routers. As far as loopbacks go, I would always run link-state protocols off Lo interfaces, even in the lab - gives you a few extra routes in the table to play with, nice to have non-direct-link routes in there to check your connectivity.

Re: Question .. CCIE lab and scheduling! [7:2461]
I was pretty sure that was the case ... With the long lead times to get into the lab I just figured by now Cisco would have wised up and realized that the standard process would be to pass the written THEN work on lab prep for at least 6 months before FORKING up $1250 to schedule a lab rather then pass the written then sign up for the lab knowing good and well that you will not pass it with paper preparation only!! I'd rather feel good about the lab FIRST then schedule it and owe Cisco the money whether I am ready or not in 6 months. For all that responded with the "go to an international test site" ... come on guys .. get real .. Pay thousands for travel or take another $200 (or now 300) test.

is it possible to mix and match flash cards? [7:2518]
For flash cards (i.e. Cat5000, 1750, 7000 series, etc.), can you just mix and match (for example, the a flash for a Cat5000 can be used on a 1750, etc.)? How about flash SIMM's (I don't think this is possible, but I have to ask)?

Re: CCIE written test questions [7:2497]
1) In short Fast Link Pulse (FLP) is used to perform autonegotiation on twisted pair media. For details see: See: http://cisco.com/warp/public/473/46.html 2) TCP slow start is flow control mechanism employed by the sender. This allows the sender to probe the maximum window size it may use for transmisson without significantly impacting throughput. It starts by transmitting data in one window chunks of a size specified by the lowest MSS advertised by each host. The transmitter calls this window the congestion window (cwnd). For each ACK received the congestion window is increase by one. Only cwnd segments may be outstanding at any one time. This increases until packets begin to be dropped. This results in an exponential growth of the number of segments that will be transmitted before recieving an ACK. See: - TCP/IP illustrated by W. Richard Stevens - "Congestion Avoidance and Control," V. Jacobson, ACM SIGCOMM-88, August 1988. 3) The CSU/DSU should go into loopback mode and instead of passing data through its framer and on to the DTE it should send the data back to the network. This is useful for circuit testing. --trey scott mann wrote: > Hello all, > > I have three questions that I cannot seem to find the answer to.

Hello, I am getting ready to test on this exam in a couple of weeks. Would someone please tell me or give me some information please. Right now to prepare, I am using the Boson switching tests and the Sybex book. I have also read the CLSC book by Cisco Press. I know it is outdated, but it still have alot of very very good info.

In this mode the sender immediately retransmits the lost packet and then halves its sending rate, continuing to send additional data as permitted by the current TCP sending window. " probably a bit more complex. What is the result of sending a loop up signal to the CSU/DSU? CL: CSU goes into a loop state - i.e. depending upon who is doing the looping, data received by the CSU is sent back to the originator, rather than passed on to the network. One of the telco ( and router side ) troubleshooting techniques used to determine where carrier network problems ( if any ) may exist. Can also indicate if the CSU itself is bad.

Re: IS-IS: Default route for L1 router [7:2485]
I would go with what works in your lab!! seriously - try putting 11.3 on both routers, then 12.1 on both, and then reverse the 11.3/12.1 (so 12.1 on L1 and 11.3 on L2) and see what happens. I would imagine that you can get away with not enabling CLNS if you have IS-IS on just a P2P link - maybe not in a multi-router environment - are you running off loopback interfaces, or just the physicals? I have had trouble with this in the past - albeit in a lab environment. I am always dubious about adding default-originates to Link-State protocols, especially in an ISP enviroment where you want a default-free environment - messing with outbound route-maps is a pain in the arse .

communities are a nice way to add an additional attribute to a route, independant of the "routing" attributes if you like - I like to think of it as "colouring" a route. what I have done in the past is use different communities for different types of route - I map communities to different "types" of route - for example, routes learned from: * downstream transit customers * upstream transit providers * per-geographical location * per-"preferance" - for instance if you multi-home a customer and wish to have a "customer-preferred" route and a "customer-backup" route the nice thing is that you can create internal policies based on the source or type of route - for instance if you multi-home to two transit providers, you can route-map a local-preference to each provider's routes, and that will propagate thru you iBGP network without having to mess with AS_PATHs or prefixes, etc. hope that makes sense check out: http://www.as3257.net/html/communities.htm for an example of how communites are implemented in the real world - some sample Cisco comfigs also Andy - Original Message - From: "Erich Kuehn" To: Sent: Sunday, April 29, 2001 11:20 PM Subject: BGP Communities [7:2486] > Can some please explain BGP communities, Ive read through Halabi's = > description of it and still dont quite understand it's use in a = > production environment. > > TIA > > Erich Kuehn > > Please no flames, I know this may be a bit basic but, Im just trying to = > understand this. > > http://1cis.com > Free E-mail Servers with unlimited mailboxes > 1st Class Internet Solutions > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=2499&t=2486 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: How to study for CIT [7:2463]
Chapter 2 of the Cisco Press CIT book started life as an edited version of the Internetworking Technology Overview. If you know your technology, you don't need that chapter. It is not taught in the CIT class, though it is included as an appendix to the student manual. You should concentrate on the other chapters, especially ISDN. The test has a bunch of ISDN questions, including quite a few things you'll never see, at least not in the US. ISDN troubleshooting can be different in other countries, I realize. You probably already know about my flash cards, but just in case you don't, see this URL: http://www.priscilla.com/cit/toc.html Good luck!

has anybody tried non-Cisco approved flash/memory [7:2498]
I need to upgrade some of my lab routers to handle 12.0 and 12.1. These IOS's are resource hogs, so apparently I need to pump up the DRAM and flash. So, has anybody tried out some of those non-Cisco approved DRAM and flash units? Don't worry, none of my routers are going to be used in a production environment. But I won't do it if these units completely blow some circuit on the router.

Re: OT- Another cool thing about Cisco (Re: Cisco fire staff) [7:2487]
I agree that there may be other reasons to what Chambers is doing. Appease shareholders by forgoing his salary? Perhaps. But, again, I would go back to my argument from before - that it's all relative. Companies always get sued when their stock price crashes. Exhibit #1 - all thosedotcoms, which crashed and burned faster than Mir. But you hardly ever see any of those execs giving up any salary willingly. Whenever execs lose any kind of compensation, it is almost always due to a mandate from the Board of Directors, and the execs fight it tooth and nail. Chambers and company gave it up voluntarily. Regardless or whether he may have done it to appease ticked-off-shareholders, he still did what very few other company execs are willing to do, and for that I can say that he is a relatively good guy.

IS-IS: Default route for L1 router [7:2485]
Hi, I have a question on case study on Doyle P.655. It says that in order to have a default route for IS-IS L1 router, the L1/L2 can have CLNS routing enabled, or have the following command: default-information originate My question is after tried this in my lab, I found even WITHOUT this command L1 router still got the L1 0.0.0.0/0 created, after I checked with IS-IS database, L1/L2 router actually doesn't have it included in LSP, so it seems that L1 router is able to parse that ATT bit and automatically create it in routing table. I don't have CLNS routing enabled either. The IOS version on L1 router is 11.3 and on L1/L2 is 12.1. After searching on CCO, the explaination of "default-information originate" command made me more confused, it says the default is only advertised in L2 LSPs if without a route-map, but in Doyle's case study router Brussels uses this command and send it to Amsterdam which is a L1 route, which one is correct ...

RE: OFF TOPIC -Job Offer without Interview?? [7:2369]
Unfortunately, you are running into something endemic to the DC area, especially the Federal government. Agencies have head count restrictions, but still need staffing. So, there have evolved a class of brokers that rent out people to the using organizations. The brokers often mark up your rate by 100% or more, although they do have to float receivables for 60 days or more. Becoming a Cisco partner just needs the right certificated people, which, at the lower level, could be the principals. As I remember, though, continued partner status also means a certain level of sales. A pure body shop won't have equipment sales. Unfortunately again, it's often easier for government agencies to deal with a small business reseller, perhaps under minority business 8(a) setasides -- they can just go make small purchases without complex procurement. Don't expect any real support from your direct employer, but keep an open mind about the client. I spent three good solid years at the US Labor Department as an ostensibly "temporary contractor," which is where I really broke into system programming and networking. Some clients exploit the system, but others recognize that it's really their job to motivate the contractors and can be quite decent to them. Good clients may find loopholes for such things as training -- they can't pay your salary to attend an offsite class, but they may have in-house classes and let you "drop in" -- even with credit. >Hey Group, > >Thanks for all the input -- I really do appreciate it. > >Just to add a few facts to this -- the company that called me -- is a Cisco >SILVER partner -- not simply a pure unadulterated head-hunter -- sort of a >hybrid (like EIGRP!! ). > >Of course it goes without saying that -- as one person said -- it's an >on-the-job-interview.

Re: X21 interconnectivity issue with MUX [7:2398]
My last e-mail was one of those mouth engaged before brain e-mails. I'm travelling at the moment, but hopefully will be able to post this before too many people shoot me down in flames. If you're using X21, then at the physical layer there will be no DCD, CTS etc. I had gone off on a tangent. Forgive me there was a lot more RS232 around when I last used MUX's. As far as I am aware the only handshaking for X21 will be Control and Indicate. If the MUX is not providing the correct signalling for this, the answer may be to loop control to indicate (back towards the router - May mean you have to make an additional female to male cable unless there is already an additional patch). Obviously you should have to do this for both routers. I am struggling to remember the pin-outs, but what you need to do is wire: Control A - Indicate A Control B - Indicate B Remember I'm talking about a loop back to the router just to fool it into thinking it's seeing the other end, not any type of cross. For some reason the following sticks in my mind, but I would definitely do a search for X21 pin-outs before making a cable: 3 - 5 10 - 12 An X21 breakout box would make things easier if you can get hold of one. If you can get the MUX's to pass Control and Indicate it would be even better. Anybody else - Feel free to chip in. I know the above works, but I would be interested if anybody knows whether there could be side effects (loss of hardware flow control cause any problems?)

Re: Cisco Question [7:2447]
If you had to select just one answer I would say DTE as there are also
non-CPE routers.
If you want to be really picky you could say there are routers acting as DCE
also, but
this usually requires some additional configuration and is not usally the
default
behavior. HTH.

Switch command questions [7:2477]
I tried to practice some switching commands on the BCMSN book with my switch (2924XL), but I found I lot of commands is completely different from the BCMSN book. BCMSN My switch e.g.1. To assign ports to a VLAN: interface ethernet 0/1 interface ethernet 0/3 vlan-membership static 3switchport access vlan 3 e.g.2 To enable PortFastspantree start-forwardingspantree portfast Is this because of the different IOS version? Or what do I have to do so that I can make my switch to use the same commands as the BCMSN book. Can anyone please shed some light on this?

IRB and CRB [7:2476]
I'm trying to make sure I've got these two straight. Here are my notes, and I appreciate any feedback on these two bridging techniques: Concurrent Routing and Bridging (CRB) Normally, a networking device either bridges or routes protocols across all of its interfaces. With CRB you can bridge protocols on some interfaces and route different protocols on other interfaces. You cannot route and bridge the same protocol on a router. The major limitation to CRB is that you cannot receive a bridgeable frame and route it, or inversely, receive a routed packet and bridge the frame. The two are separate and cannot be forwarded to each other. Integrated Routing and Bridging (IRB) IRB allows the router to bridge and route the same protocol on a router. In order to use IRB you create a Bridged Virtual Interface (BVI). After the BVI is configured, the router can send routable protocols that were bridged to the BVI to be routed. For example, an IP packet arrives on a routers interface as a bridged protocol. The destination is out another interface that is not configured for bridging. The router then sends the packet to the appropriate interface to be routed. With IRB you must configure the protocols that you want the BVI to be able to route. IRB can be especially useful as a means of connecting bridged and routed networks during network migrations when the two types of networks must communicate. It provides a border checkpoint for the two networks to pass through.

Re: 500-CS...HELP!! [7:2414]......here is my 500-CS config [7:2472]
I don't think your problem has anything to do with the "no exec" command in your config. I also use the "no exec" command for my async ports and it works great. I think the problem lies within these commands. ip host R1 2003 1.1.1.1 line 1 no exec monitor transport input telnet transport output telnet Notice that the port you specified was 2003. Port 2003 maps to line 3, not line 1. You don't have anything configured for line 3, so the reverse telnet session will not work for it. I would either try changing the port to 2001 or change the "line 1" command to "line 1 3" Let me know if this does any good.

How to study for CIT [7:2463]
Hello Group, I'm currently starting on my final CCNP exam, which is CIT. This seems like quite a strange beast to study for, compared to the other exams which focused on configuration. It seems like it mainly concentrates on show and debug commands. If that is true, how in depth do I need to know the show and debug outputs? I'm using CIT book by Laura Chappell, and Chapter 2 is one big chapter (100pages). It seems like it's missing from the actual CIT course. Am I correct?

Question .. CCIE lab and scheduling! [7:2461]
I've got a question that someone here will know the answer to. I took my CCIE written last August and due to a busy work schedule and lots of other certification requirements (AVVID, WLAN and other vendors) I have not been able to schedule my lab. Now I'm getting ready to change jobs and will immediately be looking to schedule my lab at the new company. If the written test is only good for a year ... when does this expiration kick in ? Is it based on the day you TAKE the lab or when you sign up to take the lab? With the long wait to get into the lab will I be required to spend another $200 if my lab can't happen before August? I'm sure someone who has taken the lab has been through this same scenario already. Thanks for your input ..

Re: OFF TOPIC -Job Offer without Interview?? [7:2375]
Yep .. It's basically a SCAM ... It will be contract .. it will be short term .. and it probably will be to fulfill some contractual requirement to have a CCNP onsite (at the real customers site). This could end up bad in a few ways .. Since you will be working for this fool that called you, he is the one that is obligated to pay you (not the customer site you will be working at). The next problem is that you have no idea what they want you to do! This guy and the customer could be assuming that a CCNP means you can do some things that you CAN'T do (nothing against your skill set, but I see more GREEN network guys out there today than I did 5 years ago and exponentially worst as you go back further). You could show up and have someone tell you that your job will be installing and configuring 20 DSLAMs and integrating them into their existing Newbridge ATM switch (now how much experience would you have doing that?? maybe you do .. but I'm thinking probably not). If your not working now and don't have a job lined up that would be in jeopardy if you take this one then by all means try it !! It could be a nice reality check or a lesson in what NOT to do next time!

RE: OFF TOPIC -Job Offer without Interview?? [7:2369]
Hey Group, Thanks for all the input -- I really do appreciate it. Just to add a few facts to this -- the company that called me -- is a Cisco SILVER partner -- not simply a pure unadulterated head-hunter -- sort of a hybrid (like EIGRP!! ). Of course it goes without saying that -- as one person said -- it's an on-the-job-interview. If I -- or any of the others who report on day 1 aren't acceptable -- then we simply are not there on Day 2. But what does it say about the Silver Partner?? Is this guy honest?? If he fails to properly screen the people he sends to the client -- isn't he -- at the very least -- intellectually dishonest?? And if that's true -- how would he treat his employees?? Would he promise the moon (e.g. oh yeah, paychecks every two weeks) and then not come through?? Who is our loyalty to go towars?? The client -- who we know is being given less than bargained for -- or the guy who's paying for our salary?? I already know the practical answer -- but somewhere in those Cisco books we all study -- I'm sure it also says that we are to have honesty and integrity in our dealings with clients. Doesn't it??

Re: X21 interconnectivity issue with MUX [7:2398]
Long time since I've messed with the Mux's, but thought I'd have a go as replies seem to be a little scarce. At the very worst you can console yourself with the fact that you're not the only one who hasn't got a clue. Not sure whether you were aware that both CTS and DCD are both originated by the DCE, and depending on the flow control set up, are reliant on the distand end MUX. Do you have a good circuit to the distant mux? Or, do you have a X21 breakout box so you can force DCD and CTS to see if this brings the circuit up. Failing that you could connect DTR to DCD and CTS at the router to see if that brings it up. So in answer to your question, CTS being low, probably isn't the reason for DCD being low. It is more likely that there is a problem with the MUX config or the link which is causing both to be low.

Re: OT- Another cool thing about Cisco (Re: Cisco fire staff) [7:2453]
When I mentioned all those other companies like Sun and HP, I hope I didn't come off as trying to bash them and implying that Cisco was somehow better than they were. Those companies may well have chosen to respond to the economic downturn by taking care of their employees in their own way. But I think it is safe to say that Cisco has acted in a much more humane manner than places like Marchfirst and the dead dotcoms. I tell you, not only denying severance benefits (or providing severance checks that bounce), but also refusing to pay workers their backwages and expenses, it doesn't get much more dishonorable than that.

Re: OT- Another cool thing about Cisco (Re: Cisco fire staff) [7:2452]
Stunt, maybe. But still better than nothing. For example, off the top of my head, I can't recall the CEO of any other company which has undergone major layoffs do anything comparable. Craig Barrett - Intel, Scott McNealy - Sun, Carly Fiorina - HP, Mike Armstrong - AT&T, Jurgen Schrempp - Daimler Chrysler, Bernie Ebbers - MCIWorldcom --- I haven't heard any of them do anything comparable. This group of companies is probably responsible for more than 75,000 layoffs. Like I said, I don't begrudge execs making it big when times are good. What I am sick and tired of is when the pointy-haired bosses continue to live it up when times are bad and headcount is being slashed left and right. So is Chamber's move symbolic? Yeah, probably so. Sure, he can easily afford to give up his salary. But he didn't have to do it, nobody put a gun to his head. And like I said, I don't see any other company exec's doing the same thing, and just like so many other things in life, it's all relative. So you could say that Cisco is a cool company, relatively speaking. XC ""Jason Roysdon"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > It's a stunt. His salary was like $300K.
