\31 Mak could it be used on leased lines(serial) [7:62853]
Hi Harold/all, In your description u mentioned that u can use /31 mask also, Your comments: "Since the point-to-point link is likely to have a /30 (or /31 if they're running 12.2) mask on it" questions is - -will the connection work , till now i only know that 30 is the max mask used on serial lines .how will we use this 31 mask - Does this applies only in ios version 12.2 or later as mentioned. - Do people use these 31 mask - Can anybody provide me any inf & link Thanx in Advance (Please refer the description below in thread he mentioned that.) Over a leased line I can't see the harm in leaving it running. If someone manages to get into your router, there's very little target enumeration they can do with CDP that can't be done by other means. Since the point-to-point link is likely to have a /30 (or /31 if they're running 12.2) mask on it, it's not going to be a stretch to figure out the other router's IP. While disabling CDP is certainly a sound practice on LAN interfaces, we also disable it on our switched WAN connections on general principles. That isn't a magic bullet by any means though, disabling CDP is security through obscurity more than anything else. If you're concerned about unauthorized access to your routers, then you should consider running access classes on your vty lines and AAA so you can audit access to the routers, if you aren't already. > -Original Message- > From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 11, 2003 1:12 PM > To: [EMAIL PROTECTED] > Subject: Re: Why disable cdp for back-to-back serial connec [7:62798] > > > Lawrence Law wrote: > > > > Dear Priscilla, > > > > Thank you for your clear explaination. > > > > May be it is better to disable cdp for low speed link, and > > security issue. > > CDP uses very little bandwidth, so unless it's a really > low-speed link, I > wouldn't turn it off for that reason.

RE: IOS for Home Lab [7:62830]
... it's been posted before that 12.1(5)T is supposed to be running on the Routers in the CCIE Lab. I have not attended the LAB, so I can't say for sure. I think it may even be listed on the Cisco Website for the CCIE Track. My advice- if you can afford it (and memory is really cheap), I would max out the RAM and FLASH on all of your routers.

RE: OT: New Instructor Experiences [7:62826]
Hey, for those of us who teach technology for a living, as myself, we all have those moments. What I find is that things don't go well when I get a big head thinking that I've done this before and don't need to prepare as much. It's as if I get humbled and have to work my way back up again to get "in the groove". I have also discovered that the less you mention your credentials and the more you teach what you know with a sincere concern for the students' understanding, the more respect you receive and your message gets across effectively. Show your students that you care that they learn the material and want them to succeed. Then they will have a sincere interest in learning. Since I have taken this approach, I haven't had one student fall asleep yet! Just my .02 for experience in front of countless tech classes...

One of the few really useful academic things for me was taking a dramatics minor in high school. It's not all gloom -- there are groups such as Toastmasters, which often have reasonably accessible breakfast or lunch meetings, that help a lot. Two things tend to be a problem for me when teaching. I'm deaf in one ear, so my physical position vis-a-vis the students is important, as well as the amount of machine noise in the room. Second, I often supplement the course materials, to the point that my time management may suffer. I also try to do the course as stand-up comedy, which doesn't appeal to everyone. Mind you, there was only one time I awakened someone, because he was snoring so badly that nobody could hear. He had me worried, as his sleep apnea was VERY obvious. Interesting side effect, I've noticed, of certification. Before there was any large push to certification, people really wanted the extra material. Increasingly, when I was teaching on a regular basis, students would complain, sometimes to my bosses, that I dared give them information that didn't strictly pertain to certifications -- such as the major changes in access list processing between IOS 10.2 and 10.3.

Each of these classes is a mixed bag of people: technical and non-technical, mainframe vs. non-mainframe programmers, support staff vs. design-oriented staff, technical middle management along with non-technical upper management... you name it, they're throwing it all at me and they're mixing up each group. That makes it very difficult for me; if I go too technical I'll completely lose the non-technical people, and vice versa. The nice thing is that this is only supposed to be an intro level class. Heck, it's barely a class. I'm trying to cram an intro to TCP/IP and general networking into three hours. :-) Generally, it's worked well except for today. I only have four more classes to go, spread out over the next two months. I'm definitely going to prepare differently from now on. You are correct that my success last week made me prepare less this week. I should have prepared exactly the same, but I didn't and it showed. I'm also going to change some of my materials.

Re: OT: New Instructor Experiences [7:62826]
John, A good classroom experience begins with three things: preparation, preparation, preparation! This is not to say that you didn't prepare, but each class requires additional preparation even if taught before. Another issue that arises is that every class has its own synergy. The concepts that were readily assimilated by one group become more difficult to unravel than a Gordian Knot by the next. You may have been lulled into a false sense of security by the first couple of groups and then got blind-sided by the last. I suspect that you felt your "explainer" was broken because you were only prepared to explain things in one way and ran into a group that needed it in another format. Individuals have different learning modes (preferences). A diagnostic instrument called VARK (Visual, Aural, Read/Write, Kinesthetic), developed by Neil Fleming, Lincoln University, Canterbury, New Zealand, shows how learning preferences affect the teaching process. If you prefer to learn in one mode, you tend to teach in that mode. However, if it doesn't match the preferred mode of the majority of your class, then you will have "one of those days." If you're interested in learning more about it, you can go to the National Learning & Teaching Forum at www.ntlf.com. Click on the search link and enter the search term VARK. Teachers must always be prepared to be multi-modal and have more than one way of explaining difficult concepts (and sometimes even the simple ones). I'm still searching for the "One All-Inclusive" way of teaching sub-netting to products of our marginally effective K-12 schools systems. Basic math appears to be a foreign concept to many of my students. BTW, I still have days when I think my "explainer" is broke.

RE: New Instructor Experiences [7:62826]
Hey man it happens. Some days it's like you've got a tap running into the hoover dam, and it's your job to make sure everyone gets an 8 oz. glass of water. Other days you've got that tap up and running, and the students want to know about the Gulf of Mexico. My advice would be, if you have another session with these same people, and if the next session is relevant to your recent one that didn't go so hot, start off asking a couple questions of the group that relate to the last session. There are many topics in networking that just don't sink in after only one exposure, and there's nothing wrong with somebody not picking everything up the first time. Hell, you can even make fun of yourself if you're comfortable doing it. On more than a couple occasions when I've covered ISDN and interesting traffic, I've had to stop and say "Hey, who's the idiot that taught you guys access lists???" The other thing I do to gauge how much is getting absorbed is constantly encourage students to ask questions. They'll tell you what they don't get, but they do so by asking questions. By the way, if you find that you enjoy teaching, you might want to see if there's a college in the area that participates in the Cisco Networking Academy Program. Most community colleges love getting adjunct instructors who have current industry experience.

One thing that I've discovered is *very* distracting is if I see anyone who looks bored, sleepy, irritated, whatever.

Re: New Instructor Experiences [7:62826]
John, Sounds like you had what I call a "Floating Talking Head" experience. It's happened to me before. Basically, you are in the middle of teaching, presenting, or briefing, and you experience a trippy sensation of almost being outside yourself. As you talk, your self awareness gets distorted, and you become very aware that you are forming sounds with your mouth. You are like "whoa! I am talking about stuff!" to people! Whoa! This of causes messes up whatever it was you were trying to say, or you speed up, or get goofy. There is no cure, though some professors try leather elbow patches and a pipe. Best just get some cookies and coffee and chalk it up.

Chris, Got this off of www.firewall-1.org, not exactly what you are looking for but at least you can play with the GUI until CP comes through You need an eval licence to have a fully functional product for 30 days. But if what you want is to see the GUI interface (not functionall at all), you can download the GUI, install it on a Windows Machine, and set the server as "*local".

RE: Why disable cdp for back-to-back serial connec [7:62798]
Over a leased line I can't see the harm in leaving it running. If someone manages to get into your router, there's very little target enumeration they can do with CDP that can't be done by other means. Since the point-to-point link is likely to have a /30 (or /31 if they're running 12.2) mask on it, it's not going to be a stretch to figure out the other router's IP. While disabling CDP is certainly a sound practice on LAN interfaces, we also disable it on our switched WAN connections on general principles. That isn't a magic bullet by any means though, disabling CDP is security through obscurity more than anything else. If you're concerned about unauthorized access to your routers, then you should consider running access classes on your vty lines and AAA so you can audit access to the routers, if you aren't already. > -Original Message- > From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 11, 2003 1:12 PM > To: [EMAIL PROTECTED] > Subject: Re: Why disable cdp for back-to-back serial connec [7:62798] > > > Lawrence Law wrote: > > > > Dear Priscilla, > > > > Thank you for your clear explaination. > > > > May be it is better to disable cdp for low speed link, and > > security issue. > > CDP uses very little bandwidth, so unless it's a really > low-speed link, I > wouldn't turn it off for that reason.

RE: CCIE Lab - I have seen he future and it is.... [7:62776]
I disagree, it sounds to me like Chuck is pursuing the IE for the right reasons. If his goal was to learn enough to pass the lab, and he has learned most of what he set out to learn, I can't really fault him for being discouraged. It's very frustrating having spent months or even years learning how to do 4-way IGP redistribution with no routing loops and all those other difficult but possible scenarios we subject ourself to, only to fail the lab because in a low-time high-stress environment you couldn't think of which OSPF over frame config would meet the bassackwards requirements on the lab. It's Cisco's program, and they can do whatever they want with it. But my learning curve has drastically changed since I started studying for the lab, and there are other pursuits that I'd like to go after once I'm done with the lab. Really my primary motivation at this point is that I'm not a quitter, and I want to finish what I started. I'm not pursuing the IE so I can get a better job or so I can get promoted at my current one. I teach CCNA and CCNP classes, and when I pass the lab I'll still be teaching CCNA and CCNP classes. Having studied for the lab helps me do a much better job as an instructor, but having a number behind my name won't make a lick of difference to anyone but me. > -Original Message- > From: Amazing [mailto:[EMAIL PROTECTED]] > Sent: Monday, February 10, 2003 11:13 PM > To: [EMAIL PROTECTED] > Subject: Re: CCIE Lab - I have seen he future and it is [7:62776] > > > actually, i think you have it backwardsthe CCNP of > tomorrow will be the > CCIE of todayCCC tests are getting harder...the bar is > being raised > > if what you state is truly the way you truly feel, then you > were in pursuit > of the CCIE for the wrong reason in the first place. > > sorry you're so depressed. > > > ""Charles Riley"" wrote in message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Chuck, > > > > Your post reminds me of those weird little ice cream stands that I > sometimes > > see at the mall and various carnivals.

Total is the total amount of memory in bytes available for the processor after the Cisco IOS software is loaded. It will be less than the DRAM assuming you have a router that loads IOS into memory.

Could you send us the result of the `show memory` and `show version`. Maybe it helps the discussion.

[7:62800] Hi, 1) i do a "show memory" on a cisco 26xx router. It shows me the Total Processor Memory and Total IO memory. When i add up these 2 values, why is it not equal to total amount of DRAM in your router (as shown by sh ver)??? 2)Assuming the "sh memory" output does not give us the correct picture about memory utilization, which MIBs and objects should we monitor to get the memory utilization( as a %)of the router? Or can we atleast get the "free memory" , "used memory" or "total memory" via SNMP and using MIB expressions, we can compute the Memory utilization as a %??What are the MIBs and objects to get this info?

A good starting site for lots of tutorials is www.radb.org. The RFC "Using RPSL in Practice" and the various RPSL tutorials are good starts to understand what you are trying to accomplish with your policy. There's some freeware such as RtConfig on the site, which will translate some routing policy into Cisco config language. It may not support some of the newer features, and you may not have time to set it up by Friday. My Certzone tutorial, of course, is strictly Cisco oriented. I've also written two books, WAN Survival Guide and Building Service Provider Networks, that focus on "what problem are you trying to solve", respectively, from the enterprise and carrier perspective.

Lawrence Law wrote: > > Dear Priscilla, > > Thank you for your clear explaination. > > May be it is better to disable cdp for low speed link, and > security issue. CDP uses very little bandwidth, so unless it's a really low-speed link, I wouldn't turn it off for that reason. Regarding security, if it's a private point-to-point HDLC link, then security probably isn't too much of an issue. It would be hard for a hacker to see the packets. On the other hand, if the hacker somehow got into a router that was running CDP on any of its interfaces, then the hacker could learn about one or more additional routers, and that's not good. You want to limit how much a hacker can learn. It's sort of a close call since CDP is so helpful for troubleshooting, though. How about the rest of you out there? Do you disable CDP like some security documents say to do? If often occurs to me these days that we spent the '80s and '90s developing all sorts of cool protocols to share info of all sorts, and were spending the '00s disabling most of them for security reasons.

Type no interface loopback0 The network is a virtual interface on the router, If you scroll through the running config you will see Int loopback0 Ip address 10.x.x.x x.x.x.x MAKE SURE no one needs this before delete it, Otherwise fire ahead, this will reemove it, Matbe go and research its usage before you delete it to be sure.

Thanks to all who wrote in. My Kafkaseque post yesterday apparently touched a chord (or nerve) with several folks. I was hoping to start an OT discussion on those Dippin' Dots ice cream, and draw analogies to networking. Heck, I would even settle for Howard asking a variation of his favorite question: "what is the ice cream you are trying to eat?" In all seriousness, I haven't abandoned all hope yet, it has just lessened in importance and intensity for me. In response to CN's question, I have attempted the lab at least once, Brussels, way back when the lab was a two day lab, and the numbers were still quad digits.Without violating the NDA, let's just say that I will never forgive ISDN for what it did to me. As far as my motives for CCIE chasing, the main reason I am persisting is that not only have I invested time, money, and freeze dried ice cream, but the CCIE quest motivates me to study topics that I don't necessarily deal with on a daily basis, and to practice exotic configurations with those that I do.

I don't know how this route got into the table.

Re: changing cat6000 from VTP Server to transparent mode [7:62810]
I do remember I had some problem related to it; change from server to transparent lost connectivity. It is a bad idea play with that during production time . What performance issue is that with Server mode?

Now I am going to make all of them in transparent mode(including the switch have RSM)as there is some performance issue due to broadcast in server mode. I heard that while doing so, all the vlan information will be lost in the switches. Please share with us if any of have already tried this and came across any issues.

Re: bsci passed [7:62805]
Congratulations, Alejandro. That was a tough test for me too. I passed mine yesterday morning. I'm not exactly bragging about the score but I passed. Got a lot more on IS-IS than I expected - about 20% or more of my test. Had only read about it. My home lab routers aren't beefy enough to set it up and play with it and I've never used it in the real world. Guess I read enough about it though. On to switching.

Monitoring Memory Utilization(%) on a router. [7:62800]
Hi, 1) i do a "show memory" on a cisco 26xx router. It shows me the Total Processor Memory and Total IO memory. When i add up these 2 values, why is it not equal to total amount of DRAM in your router (as shown by sh ver)??? 2)Assuming the "sh memory" output does not give us the correct picture about memory utilization, which MIBs and objects should we monitor to get the memory utilization( as a %)of the router? Or can we atleast get the "free memory" , "used memory" or "total memory" via SNMP and using MIB expressions, we can compute the Memory utilization as a %??What are the MIBs and objects to get this info?
