Re: Subject: Re: Dead console port [7:9621]
Comments within and below. Subject: Dead console port [7:9621] Okay gang, here's a challenge that I'm trying to overcome (warning: it may not be solvable) I just got a 2514 where I couldn't get any response from the console port. Can you be very specific here? Does this mean that you saw absolutely *zero* characters go by on the screen, or that any amount of input on your part did not cause any reaction on the part of the router? Of course, I tried changing baud rates, etc, When you say you tried changing baud rates, etc How exactly did you do this? I have found that a lot of folks never complete *all* the necessary steps to fully change over to a different speed setting in hyperterm. To be precise, did you do the following for each console speed (1200bps, 2400bps, 4800bps) change listed in the paragraphs below? I'll assume you are using hyperterm. If you are, you will need to disconnect the connection(phone off hook button). Once disconnected, go into the properties button (hand with a piece of paper?) and select the configure button. Change the console speed to 1200bps. Press okay twice. **Close hyperterm** and reopen it. Hyperterm is now set to read/operate at 1200bps. At this point, you would want to reload the router. Hopefully, within the first 15-20 seconds you should see something you recognize. If not, redo the procedures in the paragraph above for both 2400bps and 4800bps respectively. Once you do get recognizable text, send a regular break to the router. Use the rommon procedures to reset the config register to 0x2142: o/r 0x2142 but when I finally connected to the AUX port, I was able to get in. I assume this was the first time you tried the AUX port? also, what speed was Hyperterm's console set to when you accessed the AUX port? Remember, the AUX port speed is set with the values specified in the startup config. Since there is nothing set to interrupt that startup config, it can be any of the following possible values: 1200bps, 2400bps, 4800bps, or 9600bps. Also don't forget that somebody who was messing with the config could have set other parameters, such as stopbits, etc. The enable password was cisco, so I gleefully got into the config and changed the config register, hoping that would solve the problem. You have not mentioned what value you had and what value you changed it to. Can I presume that the config register was set to something other than 0x2102? If so, what value did it have? When you changed it back presumably to 0x2102, did you remember to reset hyperterm's console speed to use 9600bps using the procedure above? It didn't, so I did the next (very stupid) thing - I erased the config (I'm beating my head against the desk as I type). Well, if you mean to say you erased the config, I assume you meant erase startup? if so, the default settings should have allowed access to the AUX port once the router was fully booted. The big assumption here is that your hyperterm settings were set to 9600, 8, N, 1 and no flow control. If not, the AUX port may not work. Now, of course, the problem is when I go to the AUX port and try to get into enable mode, I can't (no password set). So you are able to access the AUX port, but it will not permit you to set a privileged level password via the AUX port. That is not good. The AUX port cannot be used for password recovery, but I am sure you have already figured that out. Even if you could send a break to the router somehow without using the keyboard (electrically), you would still not be able to access the AUX port to change the config register. Is there any way for me to bypass the console port by using the AUX port, Not for password recovery purposes. or have I just rendered this device useless until I find a way to fix the console port? To my knowledge, it is not repairable. The best you can do is get a Smartnet Contract for it and send it to the great router heaven in the sky (a.k.a Cisco's dumpsters :-) I don't think I can get into ROMMON mode from the AUX port, Correct. and I can't get into priveleged EXEC mode, either. Make 100% sure you cannot access the router from each of the console speeds mentioned. A router without a fully functioning console port is a disaster waiting to happen. If the console port really and truly is dead, you need to get rid of the router (hopefully viia replacement from Smartnet).

A Denial of Service atack is one that's aimed entirely at preventing you from using your own computers. There is some kind of Dos attacks : Brute force attack : A system or network is flooded - whith messages, proceses, or network requests - so that no real work can be done. The system or network spends all its time responding to messages and requests, and can't satisfy any of them. Examples are Smurf, broadcast relay, Echo-chargen One-packet kill : Attacks that involve sending small amounts of data that cause machines to reboot or hang. Examples are Teardrop, Land, Ping of Death, Land, Doom. DDoS : Denial of Service from serveral hosts at a time. I hope I have asked your question.

I may have not looked very well but maybe this should be better emphasized on books, since their approach may lead to this kind of misunderstanding. Access-class is really the solution for this case but I think it must be also applied for the console and aux ports, which could also be used to telnet to Network A. Thanks for your reply!

The issue was that telnet worked from Router B into the 10.0.0.0 network. As cheekin states correctly, ACLs will not inspect packets generated ON Router B, only packets travelling through the router, so telnet FROM Router B is possible. To prevent this, you must use the vty filter (and obviously then control administrative access to Router B). Commands are entered on Router B: To prevent telnet FROM Router B into the 10.0.0.0 network: access-list 10 deny 10.0.0.0 0.255.255.255 line vty 0 4 access-class 10 OUT (inspects destination IP address) To prevent telnet INTO Router B: access-list 10 deny 10.0.0.0 0.255.255.255 line vty 0 4 access-class 10 IN (inspects source IP address) Last comment: VTY filter should be applied consistently to ALL vty lines configured (5 is default).

Re: Multicast on the Internet - what is the status [7:9655]
hello gang: I hope some experts like Howard Berkowitz can respond: question - what is the status of multicasting on the Internet today? Both technically, and non-technically? Well, my area of specialization is unicast. I don't routinely read the multicast routing lists, but my general impression is that intradomain multicast is indeed used with increasing frequency, but interdomain still has major problems of billing, security, resource impact on unwitting operators, and resource location. But now I've noticed yet another group of technologies emerging - BGMP (which I am told is supposed to be better than MSDP/MBGP, but I don't yet understand how it is better), bidirectional PIM (which seems to be another name for CBT), and SSM with IGMP V3 (which still leaves open the question that how would you know who to block and who not to block?). Plus, I seem to see less emphasis on CGMP, and more emphasis on RGMP and IGMP snooping. While IEEE has a CGMP-like function being defined, doing things at layer 3 tends to optimize multivendor interoperability. I like the idea of CGMP myself, and I wonder if it might some day evolve to something controlled by MPLS setup protocols. But the bottom line is that I still don't see too many widespread consumer-uses of multicasting. I only see real-world uses of multicasting within companies (financial information in investment companies), or, across the Internet, meetings of standards bodies. But, for example, I don't see anything like the Superbowl or the World Series being delivered via multicast. Yes and no. ESPN does use multicast to deliver such content to subscribing television stations, but not to end users. OK, OK, that's because of corporate licensing restrictions, but I think you see my point, I don't see a whole lot of multicasting that delivers information of interest to the average user. One of the things that I personally find flawed in using multicast in distributing video to end users is that the channels are synchronized in time -- in other words, a given program starts at a given time, and if you're late, you miss it. I think a VCR-like function has more commercial appeal, where multicast is used to distribute content to video caches at the provider edge or even in set-top boxes, but the end user then can access the content on random-access storage.

RE: Use of terminal server in home lab [7:9686]
I work for a company that is quite laid-back. Therefore, when I am not busy at work, which is about 50% of the time, I usually telnet back to my home lab and work on the scenario whether it is Cisco or Juniper. I put the terminal server behind the firewall and redirect any telnet traffic that hit the firewall to the terminal server so that I can have console access to any of the Cisco devices that is connected to the Terminal server. The only thing that you can NOT do with the terminal server is to PHYSICALLY power off the router.

I was discussing this the other day at work. Where I work, many of use listen to streaming audio on our PCs, and when I asked someone to turn up a song they said, Pull it up on yours. I tried to explain that if I did, our two versions would not be synchronized and it wouldn't sound good.. I then had a discussion with my brother-in-law about using multicast to distribute video, and we used the picture a bar with 5 TVs if all 5 TVs aren't in sync then this technology won't be widely accepted. The only thing we could come up with was multicast and if used with CGMP (or a CGMP-like standard) at least at that pont, you know that each packet gets delivered to each station connected to that switch at virtually exactly the same time, at least within a few milliseconds, which is close enough to in sync IMHO. The only thing is, you would have to make your application on the TVs that receive this broadcast so that they didn't employ a buffer, or else you could run into having the buffers on the units getting out of sync. We also speculated that what you could do is to have a central unit control the buffer and timing of the playback on the collection of units (i.e. have a server in the bar that took in the multicast video and then doled it to the TVs in a manner that would let them synchronize). Alternatively, you could make a protocol that each of the end stations in a place (i.e. the bar) could run between them that would let you coordinate their own sync. The only problem with making it on demand is that your multicast infrastructure is of no use (i.e. each person would be in their own multicast group). Also by having the video on demand it would have an affect of many units close to each other being in sync (like in the bar example from above). If indeed the on demand route was taken, multicast support wouldn't be important, but QoS would be of utmost importance. The biggest problem I see with relying on QoS though is that at some point, *everyone's* traffic will need to be considered important enough.. This, to me, is a very interesting topic, because these issue represent the future of all audio/video delivery IMO. A friend of mine just implemented a huge multicast setup for a large financial firm and used the multicast to broadcast IPTV. He told me that with IPTV there was no buffer, or if there was it was small because when you clicked join this broadcast the video (broadcast quality MPEG2 video mind you) started playing instantly. I asked him about if there were multiple units in close proximity, if they were in sync. He said he'd never tried that I'm sure we'll think of something =) Mike W.

Where I work, many of use listen to streaming audio on our PCs, and when I asked someone to turn up a song they said, Pull it up on yours. I tried to explain that if I did, our two versions would not be synchronized and it wouldn't sound good.. I then had a discussion with my brother-in-law about using multicast to distribute video, and we used the picture a bar with 5 TVs if all 5 TVs aren't in sync then this technology won't be widely accepted. The only thing we could come up with was multicast and if used with CGMP (or a CGMP-like standard) at least at that pont, you know that each packet gets delivered to each station connected to that switch at virtually exactly the same time, at least within a few milliseconds, which is close enough to in sync IMHO. The only thing is, you would have to make your application on the TVs that receive this broadcast so that they didn't employ a buffer, or else you could run into having the buffers on the units getting out of sync. We also speculated that what you could do is to have a central unit control the buffer and timing of the playback on the collection of units (i.e. have a server in the bar that took in the multicast video and then doled it to the TVs in a manner that would let them synchronize). Alternatively, you could make a protocol that each of the end stations in a place (i.e. the bar) could run between them that would let you coordinate their own sync. The only problem with making it on demand is that your multicast infrastructure is of no use (i.e. each person would be in their own multicast group). Also by having the video on demand it would have an affect of many units close to each other being in sync (like in the bar example from above). If indeed the on demand route was taken, multicast support wouldn't be important, but QoS would be of utmost importance. The biggest problem I see with relying on QoS though is that at some point, *everyone's* traffic will need to be considered important enough.. This, to me, is a very interesting topic, because these issue represent the future of all audio/video delivery IMO. A friend of mine just implemented a huge multicast setup for a large financial firm and used the multicast to broadcast IPTV. He told me that with IPTV there was no buffer, or if there was it was small because when you clicked join this broadcast the video (broadcast quality MPEG2 video mind you) started playing instantly. I asked him about if there were multiple units in close proximity, if they were in sync. He said he'd never tried that I'm sure we'll think of something =) Mike W. You are touching on another subject, like MPLS control vs. forwarding, that the marketdroids tend to get confused. Multimedia does not require multicast, even though they often get lumped together. You are describing a a multicast applications that have the extra QoS requirements of multimedia, just as there are multimedia applications (e.g., VoIP) that have no multicast requirement. There are major multicast applications, such as financial information distribution, that have no multimedia aspects. In the example you cite, I would hope that the egress device at the bar is a router with enough intelligence to recognize that more than one host TV wants to join the multicast group (i.e., via IGMP). The router would then send out a multicast or broadcast frame for the group, and, with 100 Mbps or faster, I suspect the synchronization problem would be lost in the noise. Remember that you, as a human, are going to be at different distances from the various TV sets, and the sound from each is going to reach you at a significantly different time -- the speed of sound in air is far slower than the speed of electrons or photons on a cable. Indeed, you may experience different propagation times through the air and the lower tones that conduct through the floor.

Setting up Sub-interfaces on serial interface for Frame Relay [7:9697]
I am having a problem when attempting to configure sub-interfaces for a Frame Relay connection and was wondering if anyone has ever seen this problem before. I configured two routers for a point-to-point Frame Relay circuit with sub-interfaces and performed a test and turn-up with ATT which worked fine. The problem I am having is I realized after I configured the interfaces on both routers that I had used the wrong IP addresses. I setup both ends of the circuit with a subnet address of 255.255.255.252 but when I attempted to change the address I get a bad subnet mask error. I have both routers configured as IP Classless and was able to assign a /30 address to both earlier. I removed the IP address from the interfaces and tried to add a new address and I get the same thing. Is there something special with sub-interfaces or Frame Relay which is causing this problem? Any suggestions would be greatly appreciated.

Do routers forward Layer 3 broadcasts? [7:9699]
Hi folks: I keep getting this quesition. Imagine two segment routed network. Network 1 is 10.10.10.0/24 with one host (Host A 10.10.10.5/24) and RouterA's E0 10.10.10.1/24 RouterA's S0 interface is connected to network 10.10.20.0/24 with .1 address and RouterB's S0 interface is also connected to this network at .2 Now RouterB's E0 interface is connected to network 10.10.30.0/24 at .1 and there is a host HostB on this segment at .5 Assume both the routers have routes to all networks reachable whithin this network. HostA sends a packet to host address 11.11.30.255. What will happen? Many people I talked to say that the RouterA will drop the packet because it is addressed to a broadcast address. Well, there is no gaurantee that Router A knows that this is a broadcast address. Secondly, even if it does, would it drop the packet My understanding was that routers don't forward layer2 broadcasts. If a packet with layer three broadcast address for either a local network or remote network arrives at a router's interface the router forwards the packet either to the next hop or broadcasts it onto the local segment. Am I wrong? I tested this out on my network and the results are as follows. I pinged a broadcast address (172.16.255.255) of my local segment from my machine (172.16.3.16/16 gw:172.16.1.1) and I got a reply back. I pinged a broadcast address of a remote segment from my machine (172.18.255.255 and there is point to point serial connection between 172.16.1.1 and 172.18.1.1 and statich routes configured between the two networks) I got reply back. I traced a route to the remote network broadcast address (172.18.255.255) from machine (172.16.3.16/16)and the packet is forwarded by 172.16.1.1 to 172.18.255.255 and the trace stopped there. My conclusion was since Layer3 broadcasts are considered as directed broadcasts, any node on the segment can reply to the packet and in this case the first node to listen to this being the remote router it sends a reply back. Please comment.

2 problems with that. Suppose you have a new/unconfigured router, therefore with no ip on its ether port.

Re: Use of terminal server in home lab [7:9686]
The answer would be yes; however, if you change the IP address of the ethernet port of the router, then your telnet session would be LOST. The other caveat is if you apply an access-list to an interface, if you are not careful, you'll be in trouble.

I've picked up the Cisco Press MPLS book, but haven't gotten a chance to read through it yet.. But it sounds like MPLS is something I'd be very interested in understanding. I agree that there is a need to keep in mind that not all multicast applications need QoS, and not all multimedia applications are multicast. I would think, though, that if there is a digital version of our current broadcast television system, it would be implemented via multicast (using QoS for delivery). Although people talk alot of video on demand, IMHO, high quality digital video on demand at a consumer level is a long way off. Partly because of the equipment and hardware needed to support large amounts of VOD (i.e. servers, storage, etc) and partly due to bandwidth needs. For VOD, each viewer will require the full bandwidth for the video, as well as QoS to make sure it's delivered properly. At that point we're looking at millions of separate video streams all requiring priority meaning the core of the internet and even most ISPs will have to have the sheer bandwidth to pipe all of that video realtime. At least if NBC, FOX, etc were to use multicast to deliver the content, the back-end hardware requirements and bandwidth requirements between the broadcaster and viewer and significantly lower. We could even point to DSS as a precursor to this new digital broadcasting. They, in a sense, perform multicasting by sending a single signal to the sat. and then multiple people receive all of the channels. Also, the Pay-Per-View system, although close to video on demand is being achieved by showing the same movie at staggered times, etc. you see where I'm going with that In the example you cite, I would hope that the egress device at the bar is a router with enough intelligence to recognize that more than one host TV wants to join the multicast group (i.e., via IGMP).

Indeed, you may experience different propagation times through the air and the lower tones that conduct through the floor. Yeah.. that's what we were assuming is that the engress router would know all of the clients in the group. Also that, perhaps using CGMP, the router would hand off the multicast data to a switch that doles it out to the clients. I understand your point about the TVs being different distances from the listener, etc, but I still wonder that if the clients employ some buffering technique, that a small hiccup in the stream could cause the clients to become enough out a sync that, if someone were positioned between two the of clients, they would get a noticable echo from the delay. Of course, if the clients didn't utilize a buffer (played the stream live from the switch), then yeah, the clients shouldn't even be out of sync really. Aren't buffers almost always employed with multimedia applications like this to avoid disruptions due to delays introduced somewhere else during transit to the destination? Like a jitter butter or something? That's where I'm thinking the sync problem would rear it's ugly head. I would love to setup a test bar and try this stuff out! =) Mike W.

I use Firewall IOS PAT. This should allow you to connect the 2511 (or in my case a 2621) directly to the cable modem.

Re: BGP Community queries [7:9616]
Hello Mike and Bradley, My mistake, R5 is not in AS300, that should be R4, so I'm asking the possibility, how can I configure on R1 (which advertise 10.1.1.0) to send community with community 100:10, and then R4 in AS300 will prepend the network that is coming with 100:10 community (which is 10.1.1.0) from AS100 , and prepend it with 1000 2000 3000 (so AS200 will chose R2 (As100) rather than AS300 to go to 10.1.1.0 Thanks, grad From: Bradley J.

Re: Use of terminal server in home lab [7:9686]
For starts- you will be @ least a $1000 broke-er if you go the 2511 to 2600 (NM-16 or 32 module) route :o) The main difference is that it allows you to access the devices as if you were connecting to each console port directly. You are actually calling up a loopback, but ear marking it for a physical async octal cable connection with a hostname (got all that). If you Telnet into each router, some commands (like reload) will drop you to the last device you were in. This works best in larger labs (5 to 8 routers). Another reason of course is that the CCIE lab uses them it would suck to get log-jammed clearing a line or with a faulty config, when you should be focusing on other things. All the best !!!

Re: network map for campus-size network [7:9199]
One major problem with the CND is the long period time before the database reflects newer products. For example, the db update I received last week was the very first time GE was made available for the tool. To date, the db still doesn't reflect the Catalyst 3550, a very popular gap-filler switch with high customer demand. There is no telling what other products are missing from the database and you only find out when you're ready to include it in your design. The CCO configurator with your own product knowledge is still tops for putting together a Cisco design. my 2 pennies - Original Message - From: Dennis Griffin To: Sent: Thursday, June 21, 2001 8:53 AM Subject: RE: network map for campus-size network [7:9199] Prescilla...My opinions/suggestions All of the earlier suggestions are good as well (Visio, Netviz, etc.), but I also really like the Cisco Network Designer (CND), produced by Netformx (www.netformx.com). Like an earlier respondent stated, this is a high performance app that is CPU, memory and disk space intensive, BUT here are a few reasons why I like it for predominantly Cisco networks: 1. It is the standardized network diagraming tool used by the internal Cisco engineering staff. 2. It includes an active (updatable) database of EVERY currently available Cisco platform and all componentry. In fact it includes complete databases of over 70 other vendor products and options as well (from 3Com through Zircom; PCs, OSs, hubs, switches, routers, add-ons, etc.). You pay for the weekly update service. 3. The internal logic is AI, rules based and can recognize chassis, accessories, modules, blades, IOS version, memory configurations, as well as data link and IP addresses. Autodiscovery can generate a logical (Layer 3) network diagram of any SNMP compliant device (any included vendor). The report generator can produce an asset list in several forms, including by device type, vendor, or drawing level, and display model number, MAC address, and IP address(es)--great for a preliminary network audit survey or design upgrade project. Will tell you where the obsolete devices or even obsolete blades are located. You can design the network from the ground up, or capture the existing network and upgrade it. The key advantage to CND (over other apps) is that the AI configuration wizard recognizes physical configuration mistakes (wrong IOS feature set, not enough DRAM or FLASH, no compatible interface, etc.) while you are building the network, and based on the latest available components. 4. Graphics can be exported to HTML, Visio, or even bit-mapped. Text and tabular data can be exported to ASCII, Word, Excel etc. Legacy Vision diagrams can be imported to CND. Exports lose the AI logic, but imports can gain it if the device is recognized within the extensive object library. 5. As a Cisco instructor, I have used CND to document student networks in the lab, in order to verify IP configurations, and I generally recommend it as a tool option to Design class students. (I actually taught the CND Orientation class to partners during the initial worldwide deployment last year--now the classes are on-line or delivered through Cisco field offices.) 6. The price range is compatible with Netviz if all options are purchased (weekly updating and Enterprise level autodiscovery), but even without the enterprise level discovery it is comparable to Visio on steroids. The included local autodiscovery is acually more suitable for modular compilation of large networks. Lastly, I must add a kudo for your book Top-Down Network Design which I reference in virtually all of my classes, especially DCN--it is a classic and well written!! (BTW, A trial version of Designer can be gotten from Netformx or maybe from Cisco directly). Cheers...

If you're up to a little searching through the archives though - you'll see a thread or two about how Cisco is planning to revamp the written and the lab. Take your pass and don't be ashamed of it. It's interesting that the scheduling program asks for a score - since so many things on the written have been deleted from the lab, a low passing score could be all the questions on the stuff that's not in the lab anymore. So what good is knowing the score? Congrats and move on to the lab!

Re: Dead console port [7:9621]
Unfortunately, this was a used router from an auction, sold as-is... I made the fatal mistake of erasing the configuration of a router with a dead console port... but I've succeeded in restoring it. -e- - Original Message - From: Ron Goff Jr To: Sent: Saturday, June 23, 2001 9:40 AM Subject: Re: Dead console port [7:9621] I was looking for Louie's link, and it didn't come up. Considering the fact that 99% of problems are physical, plus the fact that you just bought this piece of hardware, I would look at replacement as an issue. I know that it's a pain in the ass to do this, but the reality is you could knock yourself out for two or three weeks trying to figure it out when it's simply a hardware problem. Simple analogy: I was (at one time in my young life) trying to learn about Windows NT. In order to load NT you have to create three boot disks. I had many floppy disks laying around, so I used a couple of them to create my boot disks. I ran into all these indescrimate problems along the way - no matter which disks I used, NT never worked. Feeling like a failure, I finally looked at the last hope: all new disks. Wouldn't you know when I did this everything worked like a charm. Before beating your brains out, make sure the hardware is good to go. I defer to anyone with superior knowledge P01NT Tony Medeiros wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

ISDN TA [7:9741]
Hi, I need to install a Zyxel ISDN TA to the serial port of the 2501 router. How can I configure it do dial automatically when it senses 'interesting traffic'? Any thoughts on this?

Re: Dead console port [7:9621]
BINGO! Tony is right on, and I'll share with the group how I got it working (and all my failed attempts too, so that others will hopefully benefit). 1. Tried using the Ethernet method (I have another working 2514). No go, because the new router wants an IP address from a BOOTP server (I tried setting up the good 2514 as a DHCP server but that didn't work) - oops, I just now noticed the ip bootp server config command on the good 2514 - oh well, too late problem is already solved 2. Used the Serial Line method - worked like a charm. I had to: a. Set the serial interface of the good 2514 with an IP address 192.168.2.1, clock rate 64000 (put the DCE side of your serial back-to-back cable on the good router so you CAN set the clockrate) b. Set the ip helper to my notebook's IP address c. Make the good 2514 the default gateway for the TFTP server (my notebook) (took me about an hour to figure that one out - all I could see was the TFTP software receiving the request, but no packets back through the good 2514, which had debug ip packets on. Finally did a netstat -r on my notebook looking for the 192.168.2.0 route, and that's when I realized, disconnect the cable modem and set the 2514 ethernet0 to the default gateway address that was set in my notebook) d. Set the hostname and IP address in the network-confg file to the dead routers' serial 0 IP address that it gets from SLARP (in this case, ip host dead 192.168.2.2.) e. Create a dead-confg file with (literally) one statement - enable password cisco f. Power the dead router on and watch the packets fly by on the good 2514, and watch the status of the TFTP server software Once the dead router was able to request and receive from my TFTP server AND have the TFTP server routed back to the dead router properly, I was able to successfully connect to the AUX port of the formerly dead 2514 and enter priveleged EXEC mode. Wrote the configuration, and I won't be erasing THAT configuration again! :-) Moral of the story - if you have a dead console port and no configuration, all is NOT lost. This is the kind of stuff that I really feel IS CCIE level stuff, and makes me feel pretty darned good to have recovered a router.
