RE: Connect 6509 with CONSOLE [7:17983]
The little hole let you change from the Catalyst console (normal patch cable) to the Cisco router console cable (rollover) I just wish all Cisco devises came with this, then we would not have to carry around the black or blue rollover cable. -Original Message- From: Rik Guyler [mailto:[EMAIL PROTECTED]] Sent: Friday, August 31, 2001 4:40 AM To: [EMAIL PROTECTED] Subject: RE: Connect 6509 with CONSOLE [7:17983] Hmm...I don't know what the little "hole" is but accessing the console on a 6509 is just like any other device.

My HyperTerminal setting is: 9600 bits per second, Data bits = 8, Parity = none, Stope bit = 2 (as indicated on Cisco.com), Flow control = none. There's also a little hidden hole right next to the CONSOLE port labelled as "Console mode...". I don't know if I have to change something to access the console?

RE: what is mean there is a loop on the interface??? [7:18052]
It means that the LEC has a loop in the circuit. This is not a good thing. Call your Service Provider and have them take your loop out. I would also check your own network to make sure you are not providing the loop yourself such as with your CSU or a hard loop.

RE: Catalyst Q. [7:18036]
We implemented a separate management VLAN and the SUP card is on that while its connection upstream trunks the management VLAN and the VLAN used by the other modules in the CAT. We then use two dual-homed Linux boxes (backup in case one fails) to gain access to the management VLAN. The firewall on the Linux box both protects the management VLAN and limits access to the Linux hosts. Since we have the Linux systems for that, we take advantage of having them and use one of them as a syslog server. Another method would be to put the systems needing telnet access on the management VLAN. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Cisco Lover Sent: Friday, August 31, 2001 1:21 AM To: [EMAIL PROTECTED] Subject: Catalyst Q.

What should be the strategy so that no outage occurs. What do u mean by failover bundle ? IS the second PIX capable of working as standby unit.Do u have the license or key to opearate this second box as standalone unit (else it wont work !).As I know the standby would have been connected to Primary and so when primary fails the secondary will take over and the automatically continue as Primary.. "it will show this host Active". -- I think if we put the new PIX >(without >any Config) to the Primary end of Failover cable it would be the >Active and >would sync all its config to the second box (that would be a >disaster) Would this work ? What type of connection do u have. which PIX model and what version of IOS. Can u get the setup info ,how it was connected and so on. If primary is down totally and secndary does not have any config u will have to key in the config ?? is it not. Anyone correct me if i am wrong ? HTH.Let me know.

Serial1/0 is up, line protocol is up (looped) : What the line besides means is that there is a physical loop on this serial circuit . This loop could have been given on the physical circuit from your serail circuit's remote end or it could have been given from your PCM or OFC provider.You will have to contact the agencies mentioned to have the loop made through for your circuit to be up .

**WARN AS MANY PEOPLE AS YOU CAN.** If you receive an email entitled "Badtimes," delete it immediately. Do not open it. Apparently this one is pretty nasty. It will not only erase everything on your hard drive, but it will also delete anything on disks within 20 feet of your computer. It demagnetizes the stripes on ALL of your credit cards. It reprograms your ATM access code, screws up the tracking on your VCR and uses subspace field harmonics to scratch any CD's you attempt to play. It will program your phone auto dial to call only 0055 numbers. This virus will mix antifreeze into your fish tank. It will drink ALL your beer. FOR GOD'S SAKE MAN, ARE YOU LISTENING? It will leave dirty socks on the coffee table when you are expecting company. It will replace your shampoo with Nair and your Nair with Rogaine, all the while dating your current boy/girlfriend behind your back and billing their hotel rendezvous to your Visa card. It will cause you to run with scissors and throw things in a way that is only fun until someone loses an eye. It will rewrite your backup files, changing all your active verbs to passive tense and incorporating undetectable misspellings which grossly change the interpretations of key sentences. If the "Badtimes" message is opened in a Windows 95/98 environment, it will leave the toilet seat up and leave your hair dryer plugged in dangerously close to a full bathtub. It will not only remove the forbidden tags from your mattresses and pillows,it will also refill your skim milk with whole milk. **WARN AS MANY PEOPLE AS YOU CAN.** And if you don't send this to 5000 people in 20 seconds you'll fart so hard that your right leg will spasm, shoot straight out in front of you,sending sparks, that will ignite onto the person nearest you.

This is actually very easy to do in the server OS (I admit, I'm an NT guy). Simply put both IP's in the gateway list with the priority opposite on 14. I guess you could also create 2 HSRP routers and split the assignment on the servers.

On the end that is establishing the ppp session (dialing up maybe?) you will need "ppp chap hostname xxx" and "ppp chap password xxx" in the interface config.

RE: what is mean there is a loop on the interface??? [7:18052]
If you do a "show conf", you can see if the interface has been placed in loopback on the router. If you can see a loopback command (for example loopback dte) on your interface, simply disable it: router# router#conf t router(config)#int ser 1/0 router(config-if)#no loopback dte router(config-if)#end router#wr mem If you cannot see a loopback in the config, if must have been placed on your CSU/DSU or at the local NIU.

RE: what is mean there is a loop on the interface??? [7:18052]
It means simply that you line provider has been testing the line between your site and their exchange or CO. They send a signal down and it is looped back so they can verify the line is good. In order for the line to work as far as you are concerned you must call them and get them to take the test loop off the line. The (Looped) will then disappear and you should have end to end connectivity.

Weird SNMP message..... [7:18083]
Hello all I've noticed a weird trap in HP OpenView that comes up (seemingly random). It's coming from a 5500 switch. We have two of these switches configured identically (except for stuff on the MSFCs, but that's not where the trap is coming from). We get this message from one of the switches, but not the other: System NVRAM has changed Sometimes it goes hours without this message then sometimes we get this message 5-10 times within a couple of minutes. Any ideas on this? TIA, Mike W.

Re: Working ISL/DOT1Q config [7:18070]
Put the word "Native" after the "encapulation dot1q 1" on interface fast0\0.1 In the dot1q world, the native vlan for the port,(vlan 1) is not tagged or encapsulated in the dot1q frame. Hence the need for the command. Your native vlan for the trunk port (2/34) is vlan 1 accourding to your config cus you didn't assign it to anything else.

RE: I have a customer who... food for thought - static routes [7:18089]
Let me throw in some thoughts. Why are static routes not scalable? People start muttering about "lots of configuration." But doesn't your customer use some sort of database, or at least spreadsheet, to keep track of which subnets have been assigned, both to access links and user LANs? Even if DHCP is in wide use, there still should be a log. Given this addressing information, it really isn't hard to write a program that generates static routes from the address assignments, and then sets up a TFTP file to be merged into router configurations. Depending where you are in a routing hierarchy, statics also can be summarized. This is a little harder to do automatically, although there are tools such as CIDRAdvisor from Merit. The summary statics may be sufficiently rare (e.g., POP level) that their manual configuration is fairly trivial. Oh -- another reason people worry about static routes is "they don't respond to failures." How many of your end users have alternate connectivity that dynamic routing could find? In any case, will static routes be flushed if the next hop disappears? >There have been several good replies to my post.

Re: Real BSCI Exam Questions! [7:17905]
It is a beta test which means some of the questions you failed or passed will not show up on the production test. I am guessing if you passed a question that did not make into the production test question pool, Cisco gave you credit. On the other hand, if you failed a question that Cisco decided not to use in the production test pool. I am fairly positive that Cisco did not count that against you. Your raw section average is 67.75%. Cisco might be assignment different points to questions. In that case, percentage of right vs. wrong has less meaning. If you passed higher value questions and missed mainly lower value questions, you could have a low percentage and still pass. Basically, it is all guesses until Cisco reveals more beta testing details. -- "Through Complexity there is Simplicity, Through Simplicity there is Complexity" David L.

Re: PIX static command and em_limit - SYN attack [7:17994]
I put 4 for max_conns and 100 for emb_limit. I haven't got any hard evidence that this is the best way for a webserver, but it works ;) emb_limit just limits how many connections are held that have not completed the TCP 3-way handshake, thereby stopping SYN attacks from reaching the server. Once emb_limit is reached, subsequent attempts are dropped until timeout is reached on other held connections. Subsequent connections from that source IP will be dropped to keep it from keeping emb_limit full. Otherwise you'd have a DOS of your own making just from setting this value. If you wanted to truly set this at realistic values you would have to do some testing to see what normal embryonic connection values you have during peak hours under normal circumstances. Just my way of thinking, but I'd add about 50% - 200% to that value just in case you get a sudden influx of legitimate users trying to access the server. Keep an eye on log files for the server (assuming it's a web server and you log this information). In IIS and Apache it will tell you how many users dropped connection, gave up before it loaded, etc if you have a log file analyzer (I use ANALOG - it's free). Obviously setting this too low could make end users fairly angry. ;) Again, IMHO, Max_conns should be set to whatever you believe the max # of simultaneous users your server can handle. The only way to get a true feeling for what this is would be to download some software to test the limits of your server. I know there are some free ones out there but I haven't used any myself. Web development took care of that for me. ;) Sooo...umm...I guess you could say there really isn't an answer that applies to everyone. Obviously someone like yahoo.com would have much higher numbers on both settings compared to Joe Blow's web page on raising hampsters. Did I help? Confuse? Either way I accomplished something on only 1 cup of coffee ;) (by the way, that's a disclaimer for any inadvertant idiotic comments made above).

FTP Anomaly (Comments wanted) [7:18103]
Get this. I have a 6509 (actually 2, and this happens on both) running Native IOS 12.1(8a)E. (although this problem happens on all versions of Native IOS that I've run) I setup an FTP server with username "cisco and password "cisco" I issue the following commands on the 6509: ip ftp username cisco ip ftp password cisco no ip ftp passive (passive mode doesn't work on my FTP server software) When I give a "copy ftp:/// sup-bootflash:" command, the following happens: 1) It logs into the ftp server, and gives the RETR command and from my FTP server software I see the user logged in and a download starts and goes around 80K/sec. 2) The file "finishes", but the 6509 issues an ABOR (or QUIT), it re-logs into the FTP, and starts the file transfer again (at around 80K/sec like the first time) 3) The file "finishes", but the 6509 again resets the connection and starts the download once more.

Re: pix outbound vs acl [7:18101]
Well in the 5.1 PIX users manual it has a note in the section on outbound saying it's been superceded with the access-list command. It's in the command reference section. It says the recommend migrating outbound command statements to access-list command statements to "maintain future compatibility". Sounds like a hint of possibly removing it just like they keep hinting they're going to do with conduit commands.

Re: I have a customer who... food for thought - static routes [7:18108]
I just quickly glanced at the 827 docs on cisco.com, so please correct me if I'm wrong about them. According to the docs, you can configure the 827's for bridging or NAT. You could avoid static routes on this edge of the customer's network entirely (except for defaults on the 827's). The 7206 would see all of the home networks as being directly connected. NAT overload would probably be my first choice because the 827 could assign addresses to the home pc's with DHCP, so the users wouldn't have to configure anything, and any number of home pc's would just share the 827's wan interface address. No need for statics at all.

Re: Can you pass CCNP w/o having Cisco gears? [7:18107]
During the time from when I took my CCNA, 02/2000, and passed my first CCNP test around 02/28/2001 and finished my CCNP on 06/27/2001. I rarely had to support routers at work. If I had a issue that involved routers, I call the group that oversaw the routers. We worked the problem together put I never was allowed to login to a router or used a console connection to the router. Disclaimer: I have three routers at home, but I mainly used them to verify command usage, like which router mode was required for various commands. I have extremely little Catalyst experience. I have had jobs in the past where I did directly support routers. Also, I test well. Now to answer your question. Yes, with the books, (CiscoPress and Sybex) and study guides, (ExamCram and CramSession from Brainbuzz) that are available and various companies that provide sample tests, (CiscoPress, Boson). A person of reasonable ability and intelligence could pass the CCNA, CCDA, CCNP, and CCDP without ever seeing, touching, or otherwise using ANY Cisco product whatsoever. I also do not recommend this course of action lessens the Cisco certification process. My current job, I am the Network Manager. Where I and my staff directly support all the companies Internetwork equipment (Switches, Routers, Hubs) plus servers and the company Firewall, and unfortunately DESKTOPS. -- "Through Complexity there is Simplicity, Through Simplicity there is Complexity" David L.

The equipment is the following: 1 7204VXR 1 3660 1 3640 1 2511 1 2501 1 2513 1 2504 2 4700 1 cat5000/supIII/NFFC 1 as5200 w/ modems 1 as5300 w/ modems 1 cat3512 all of those routers that are modular are pretty much PACKED. i will try and put together any hardware configs you request, but some of them i might not be able to do. there are end stations running various OSes, MAUs, hubs, and assorted other things available for use with the lab. the price of 50 dollars an hour might change for you depeneding on how much time you want it for. contact me via email if interested -Peter Slow -Original Message- From: Donald B Johnson jr [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 28, 2001 9:15 AM To: [EMAIL PROTECTED] Subject: Re: $10 Vitual CCIE/CCNP LAB NOW AVAILABLE [7:17490] They also say that they have CCIE's on staff to deploy for all your networking needs.

RE: VPN throughput [7:17943]
Tom, you have to remember that when using an Internet VPN, there are a lot of pieces of equipment between you and your corporate VPN server. Each of those ISP routers and switches add some latency, and on top of the additional latency there is likely to be more jitter. (variable latency due to variable traffic patterns) Given this, depending on how many hops are between your ISP and the ISP of your company, it may very well be that there is more latency on your 50kbps dialup VPN and this latency can translate into slower response. There may also be some packet loss involved that could hurt performance as well. If you truly want to see "best case" performance on your VPN, you'll need to dial directly into the same ISP that connects your VPN box to the Internet. Even then, the performance may not by much better than direct dial, a lot depends on the quality of the ISP. (ie. Tier 1 vs mom and pop) HTH, Kent -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Tom Richs Sent: Thursday, August 30, 2001 1:47 PM To: [EMAIL PROTECTED] Subject: VPN throughput [7:17943] I have a T1 coming into my VPN 3000 Concentrator.

RE: Can you pass CCNP w/o having Cisco gears? [7:18107]
Rick, Yes. You can pass CCNP w/o have Cisco gear. Having gear helps, of course, but you can learn the concepts and commands without gear. Personally, I used the Cisco Press and Exam Cram books for each of the CCNP exams along with Exam #1 and #2 for each exam from Boson. Good luck! Mike W.

RE: Can you pass CCNP w/o having Cisco gears? [7:18124]
Having recently just passed CCNP this year I will say you must have a Router. The reason is that the prescribed rituals must be performed in front of the Router. Without a Router the powerful spirit of routing, BGPOSPF, wont bless your efforts and even if you do pass all knowledge will be removed from you within 2 months. Some have said scrificing your most valuable possesion before the router helps. I give it my time which seemed to work well. Others have given the Router spirit money, bought it accessories, even food but so far time works best.

RE: Can you pass CCNP w/o having Cisco gears? [7:18124]
Sorry Dan, but you definitely don't have to have a router. The questions come in many cases, word for word from the official course. Going through that (or the Cisco Press version) is good enough I'm afraid. Search the comments for my previous tirade to Cisco on the relative ease of that exam.

Khalid, In the nicest possible way - Preparing to be a CCIE does not include reading braindumps - If this is what you want the become an MCSE - thats easy - I know I was an MCSE (Until they invalidated it by changing the exams)years ago and then realised what a complete and utter waste of time it was Preparing to be a CCIE includes the following: 1 - A lot of hands on work and practical experiance - 4 years plus 2 - Being able to spot the errors in the books that are published 3 - Reading the better books around - Doyle/Halabi/Caslow/Kennedy etc 3 - Dedication Remember you cannot braindump a lab exam Best of luck in your efforts - but learn properly - you'll come unstuck in a big way otherwise.

Re: An Interesting routing+Sw Question:LAB Q [7:18026]
Correct !! HSRP with different standby groups is the solution. One router interface on each router is serving 2 HSRP "virtual IP's". You just stagger the priorities so one router is primary for one group, and the other is primary for the other group. Best way to explain is by router config: Router 1: Interface Vlan 1 ip address 152.1.1.1 255.255.255.0 standby 3 ip 152.1.1.3 standby 3 priority 110 prempt standby 4 ip 152.1.1.4 standby 4 priority 105 prempt Router 2: Interface Vlan 1 ip address 152.1.1.2 255.255.255.0 standby 3 ip 152.1.1.3 standby 3 priority 105 prempt standby 4 ip 152.1.1.4 standby 4 priority 110 prempt I don't know what book this came out of but the Cisco press "LAN switching for CCIE's" goes over this type of setup. This used to be used a lot; (putting two gateway addresses for the same network for load balancing) when routers were slow. i.e. the RSM. With today's fast MSFC routers, you don't really need this kind of setup as much.

Re: What's the diameter of your switched network? [7:17489]
Don't let PETA hear about you guys doing all this dissecting! Prof. Tom Lisa, CCAI Community College of Southern Nevada Cisco Regional Networking Academy Priscilla Oppenheimer wrote: You won't see any problems with max age if you leave it at the default of 20 seconds. The seven hops comes from conservative estimates of how long it takes a bridge to take in the BPDU and propagate it. With 7 hops each could take about 3 seconds. There's no way that switches these days take that long. In fact, switches don't even bother to figure out how long it takes. They just add 1 second.

Reseting Supervisor Engine and/or MSFC [7:18138]
Hi All, My 6509 has dual Supervisor Engines and dual MSFC cards. It runs in Hyrid mode. I plan to upgrade the IOS of the MSFC cards only, NOT the Supervisor Engines. I wonder: 1. Is IOS version of MSFC dependent on the CATOS version of Supervisor Engine? 2. When I reset after the upgrade, do I have to reset the whole module (Supervisor Engine + MSFC) or just the MSFC? If I cannot reset only the MSFC, in what mode should I issue the reset command? CATOS or IOS in this case (IOS is in session 15 or 16)? Will this reset both the Supervisor and the MSFC? 3. Should I not losing the configuration which I assumed they're saved in NVRAM of the MSFC or Sup. Engine? Again, Thanks much to All!!! Thomas N.

Thomas, The CAT OS and the IOS on the MSFC's can be upgraded independently in the 6500s. You can reset just the MSFC. I log into the MSFC and enter the 'reset' command while in enable mode.

yes - sheer numbers of devices in the shared bridging domain. we are talking 500 to a thousand home users, many of whom are technically savvy folks who may have reasons good or bad to connect multiple devices to the home part of the remote access network. not to mention the fact that bridging would mean direct and unrestricted access from each of these home guys to eachother.

NAT overload would probably be my first choice because the 827 could assign addresses to the home pc's with DHCP, so the users wouldn't have to configure anything, and any number of home pc's would just share the 827's wan interface address. No need for statics at all.

effective today, I became responsible for creating and maintaining that database, until such time as we hand off to the maintenance and support people. :-0 this is an interesting project for a lot of reasons, not the least of which are the layer 8 and above issues. Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Howard C. Berkowitz Sent: Friday, August 31, 2001 7:40 AM To: [EMAIL PROTECTED] Subject: RE: I have a customer who... food for thought - static routes [7:18089] Let me throw in some thoughts. Why are static routes not scalable? People start muttering about "lots of configuration." But doesn't your customer use some sort of database, or at least spreadsheet, to keep track of which subnets have been assigned, both to access links and user LANs? Even if DHCP is in wide use, there still should be a log. Given this addressing information, it really isn't hard to write a program that generates static routes from the address assignments, and then sets up a TFTP file to be merged into router configurations. Depending where you are in a routing hierarchy, statics also can be summarized. This is a little harder to do automatically, although there are tools such as CIDRAdvisor from Merit. The summary statics may be sufficiently rare (e.g., POP level) that their manual configuration is fairly trivial. Oh -- another reason people worry about static routes is "they don't respond to failures." How many of your end users have alternate connectivity that dynamic routing could find? In any case, will static routes be flushed if the next hop disappears? >There have been several good replies to my post.
