Keep in mind that CCNA is a prerequisite for CCNP, so you need to pass that first. I'd say that CCNP in one month is all but impossible with little to no prior knowledge.

Edit: Oh yea, bootcamp.

Dang. What OS are you running? I suppose if you're running some sort of Unix-ish environment you could set up an expect script to telnet to and execute commands on the router. If it's Windows though, I'm not too sure :(

Crossposting from the cert megathread:

I'd like to pick up a router with a FE port and I think the most economical is the 2620. Will I be kicking myself if I opt for the 2620 over the 2620XM? They both seem to have the same 1NM/2WIC slots. As far as I can gather the memory limitation of the non-XM model will prevent me from running 12.4 -- is that something that'll be important come CCNP time or what?

My FE requirement is for testing router-on-a-stick fyi. I'll pick up the XM if I can find a good price on one, but I'm in Canada so I'm trying to buy local and avoid border fees/international shipping rates/etc.

Guys. I'm still kind of scratching my head here. This is basically a continuation on my last help for router recommendations.

I'm still building my CCNA lab but I've got an eye on CCNP in future so I want a few routers that will handle 12.4.

The economical options are basically a Maxed out 3640 or a 2600XM. Is there any advantage to going with a 2600XM over a 3640? The prices certainly heavily favour going with a 3640 64/16 and upgrading the memory. I mean, for the price of one 2600XM I can buy two or even three baseline 3640s each loaded with a NM1E2W, judging by a quick ebay scan.

Ciscokits seems to mix and match the 2600XM and 3640 in their Advanced CCNA/Starter CCNP kit.

I've been trying to do as much research as I can, but for the life of me I can't find a good reason why I'd go with a single 2600XM over two or three 3640s + a little cash to upgrade at this point.

Feb 25, 2003

 
 
Yeah, I think I'm going to pull the trigger on the 3640s and a few support NMs. I don't have anything against the 2600XM but it looks like these will do just about everything I want in the forseeable future, at least through the CCNP track. Apples to apples the 2600XM is still a good deal because the NM-1FE2W is still pretty expensive but I only need one router to support FE at the moment, so dropping a hundred bucks on an NM-1FE-TX while loading the others with NM-1E2Ws and WIC-1Ts is a pretty economical compromise.



Also it looks like this is basically a badass frame switch platform. Pick up a cheap 64/16 chassis, load it with four NM-4Ts and you'll never want for a lab serial port again :fap:

I just took delivery of a bunch of 3640s and one of them has "bittorrent.pdlm" and "kazaa2.pdlm" listed when I 'show flash'. From what I gather this has something to do with QoS. Are these going to be safe to purge or are they somehow related to IOS?

Those are protocol definition files for nbar recognition. Feel free to get rid of them, I think those definitions have been migrated into IOS at this point.

Thanks, sounds like I'll be wiping these down then.

Also, does anyone know why a 2620XM would report a network module as UNKNOWN? I've tried my NM-1E2W, NM-2E2W, and NM-1E1R2W, and none of the above registe any interfaces. Could it be a defective NM port on the router or does the 2620XM just not support older NMs?

That's the best news I could have hoped for. I actually don't intend to put any NMs in the 2600 but since I have a 90 day warranty on the router I wanted to make sure it (the slot) worked. I'll see if I can't borrow a NM-1FE-TX or something to test it with instead. Thanks!

I'm just a beginner at this stuff myself so take this with a grain of salt but unless I'm misunderstanding your setup I don't think you need the ASA actually doing any WAN routing. Just connect both WAN uplinks (T1 and Cable) to your 1800, get a routing protocol advertising routes between offices. I think you might need to still set up a VPN over the 1800s' cable WAN interface.

But the routing protocol should essentially take care of all that failover for you.

Spanning tree putting a port into blocking mode also changes the port's status light to amber, correct?

Just want to make sure that my port isn't dying or something. So far blocking mode is my working hypothesis but I can't find confirmation on Cisco's site.

I can't actually find a simple answer to this, maybe you guys will know.

If I buy a 3550-SMI, what exactly would I be buying from Cisco to enable use of the EMI IOS? I know the part number is CD-3550-EMI=, but is it physically some kind of chip that enables use of the EMI features or is it just a license to install the advanced software?

I'm not trying to be sneaky and :filez: about it, but I want to know if I buy an SMI L3 switch today if I'll be able to upgrade any 3550 to EMI down the road when I actually need to study those features, or do I need to buy a 3550-SMI that has specifically been built to be upgradeable to EMI, if that even makes sense. Hopefully someone gets the gist of what I'm trying to ask.

Our job titles were basically meaningless. Not bad for a resume though. I don't feel too bad putting it on there since I don't ever plan to go back into Software Engineering so there's no chance I'd ever be hired to work on actual software based on that.

I went a little out with my setup and picked up three 3640s, one 2600, and three 2950s. I wanted a kit that I could use after CCNA as well though, and the money was there so I figured why not. I really wanted the 3640 so I could throw a bunch of NM-4Ts in and do frame relay, but also be able to use it for something else if I didn't feel like running a frame setup. I forgot why I ended up buying the 3640s other than they were pretty cheap.

All my equipment came from cablesandkits.com. I can't recommend them enough.

Also just finished Network Fundamentals, beginning routing and switching on the 12th. Can't wait!

I initially had nothing but trouble with the kit they sell on monoprice.com, so if you're using Windows I would recommend staying away form it. The driver disc they provided was a mess of divers with no obvious clue as to which one should be installed.

That said, I did end up getting it working and it worked fine after some driver hunting. It also has great open source drivers for MacOS and I think it works out of the box on Linux. Since I use MacOS on my Dell 10v netbook it's a perfect solution.

I'm looking to get some lab gear to study for my CCNA. I purchased a $80 piece of crap lab simulator software from Sybex and it doesn't even have a quarter of the commands available on it's 2600 router console. Since I feel as though I've been ripped off, so I'm looking for the real deal. I'm currently looking at a 851 router for around $115 on EBay. Does anyone have any idea if this router would be suitable for study purposes? Is this a good price? Can anyone recommend something better for study? I don't want to make the same mistake twice. Thanks guys.

A single router isn't going to help you much in the long run. Instead of a simulator, why don't you go to cablesandkits.com, buy a Cisco 2600 for like $50, then TFTP the IOS off of the router and use it in GNS3 (dynamips). 100% commands because you're emulating the hardware and running real IOS. And of course if you have access to IOS images then you don't even need to buy the router.

If you're going to spend money on something, I would recommend emulating the routers and buying three 2950 switches to practice your switching component instead. You can still do things like physically connecting Dynamips to a network card to let you practice things like Router on a Stick.

In the end though, there's no good way to patch this together. If you're going to go full-on hardware then you probably want to build a good CCNA lab which is at the very least two or three 2950 switches and probably at least two or three routers, though I think you can scrape by with 2500 series.

If you don't like dynamips, I think like Sojourner said, packet tracer is probably your best bet. It might not have 100% of a real IOS' commands, but you can safely bet that if it's not a supported command then you won't need it to pass your CCNA. I would go that route personally, if I hadn't already built a thousand dollar lab :v:

This might be a terrible question, but I'm having trouble wrapping my head around IOS releases. Are the release names strictly linear, wherein 12.3YZ line is always going to be preferable to the 12.3XD line? Why are we jumping from XD to YZ anyway? Is there any significance to the letters other than incremental tagging? If so, why not just tag them numerically like Cisco already apparently half-does.

I don't mean the feature sets -- those I pretty much understand at this point. It was actually tooling around the Feature Navigator that got me wondering about this mish-mash of nomenclature.

Also, desperately need more memory for my 3640s. 72pin SIMMs are so hard to come by these days :(

In general if they increment something on the letters immediately following the parentheses it's going to be for feature/hardware support. If they increment the following number/letters it identifies the bugfix/maintenance release.

So to answer XD->YZ, it would be for feature/hardware support (given a jump like that, probably hardware support to simplify support for the new hardware so people don't try load earlier unsupported code). If it was XD1 -> XD1a it would be a minor bugfix (usually a quick patch release for something horribly broken). And XD1a -> XD2 would be a regular maintenance patch release.

Thank you, that does actually clear things up a little. So obviously I don't have a support contract with Cisco so this is entirely pie in the sky, but looking at Feature Navigator, is the best option for any given router still the "latest and greatest" according to Cisco as long as it fits within your memory and flash footprint? Or are there times where you'd actually look to put something other than the newest release on a device, if both the newest release and the older one support the same feature set?

Sorry if the question is obvious, but I haven't had to deal with an IOS revisions since I worked with 7200s at a datacenter in the early 2000s, and then we had a contract with Cisco so I didn't really do much of the legwork. Most of my current experience is centred around my home lab where I just the newest 12.3 Telco IOS from one of my 3640s and deployed it across the remaining four after backing them up.

Hey, Just about ready to take my CCNA, besides a job in the industry, and besides books, whats the best medium for studying? (Reading does Noooooothing for me) Is there a creamy middle between the "watchability" of CBT nuggets and the all encompassing knowledge of the train signal videos?

If you have the money, take the CCNA curriculum if offered at your local community college. I'm doing that now. I could probably fast track it and just cram for the exam, but I like the hands-on labs (not so much in CCNA1, but more throughout the rest). They teach from Cisco's own Exploration material which tends to be more concise than their own Official Certification Guides, so when you do have to do the reading yourself it's not incredibly dry like the book.

I study better in a classroom environment myself. I've gone through both CBTNuggets and Train Signal multiple times, but being able to ask my instructor questions is much more helpful than listening to Jeremy crack jokes for five minutes between issuing an IOS command, or listening to Chris Bryant drone on like a robot for an hour. Which isn't to say that the other two haven't helped me by laying down the foundation.

I typically hit the books only if there's something I really want to learn more about in detail. Also the CCNA command reference is pretty handy at times, but seems like more of a crutch than anything.

If you're in a hurry, this probably isn't the best way to do your CCNA. It's a full year at least, or at least a few months if you can double-up on classes. I'm not in any particular hurry on the other hand, and being able to sit down and digest the classes for a week really helps. I'm not in any pissing contest with anyone to fast track the CCNA so this really is the best method for me.

What's your knowledge of subnetting right now? VLSM isn't difficult at all if you realize that all you're doing is splitting an existing network down into smaller subnets by logical chunks.

Are you having trouble with the concepts or the implementation?

If you're having trouble with the implementation, the best thing I can recommend is to remember that all your hosts have to fit as efficiently as possible into your available subnets which are powers of 2, and you need to start with your largest networks first.

For example, a subnet that needs 28 machines would do best on a subnet of /27 that allows for 32 hosts. You'd be wasting a /26 unless you knew you needed to plan for future growth. Just start carving your available addresses down into smaller subnets and do your point to point WAN links last since they only need two (usable) addresses.

Don't forget to take into account that one address is broadcast and one is the network ID. Typically you won't be assigning these so you're losing two addresses off the top.

So looking at your example, consider what each subnet they want you to assign fits best into. Look at it really carefully to make sure that all your hosts will fit after you consider broadcast/network id.

The reason you want to do your largest networks first is that if you create a network with four addresses at the start of your range, then you need a network of 100 hosts, you'll be able to use a.b.c.0-3 for your first subnet but then you'll need to use a.b.c.128-255 for your second subnet. You just wasted addresses 4 through 127. There's actual binary math behind this, but I don't remember any of it, and it's a lot easier to think of it logically than it is to binary math it out.

As dumb as it sounds, maybe check youtube. There are a few VLSM tutorials where people go through it step by step. I can't speak for how clear they are because I'm not ready to spend 30 minutes going through a video about VLSM :v:

NTP v4 supports IPV6 synchronization, however digging through Cisco's support site I came across this:

NTPv4 was introduced into Cisco IOS Software: 12.4(15)XZ, 12.4(20)MR, 12.4(20)T, 12.4(20)YA, 12.4(22)GC1, 12.4(22)MD, 12.4(22)YB, 12.4(22)YD, 12.4(22)YE and 15.0(1)M.
