Just getting started with ICND1, need a pep talk

LayOffPayOff · January 2012

Im pretty frustrated, I think I just need to vent. Hopefully some of you will be able to give me a shove in the right direction.

Last week I started watching CBT Nuggets for ICND1. Im about half way through and I decide I want to start getting some hands on experience. I was laid off in October, but before I left I told my manager I wanted to go for the CCNA and he gave me some hardware that had been retired. This is where where my headache begins.

-Strike 1: What appears to be a model 3620 router (no clear printed model number, i made a guess based on the s/n sticker). Unfortunately it doesn't use a standard power cable and I dont have the adapter. The thing looks pretty shabby, is it worth my while to get a plug for it?

-Strike 2: A model 2811 router. It powers on and Im able to access it using a console connection. It makes so much noise I want to jump out the window. It appears to only boot to "rommon" mode with the following error msg: "cannot determine the first file name on device "flash".
Following some directions I found online, I set up a tftp server and used "tftpdnld" to download a new copy of IOS to the router. (I have no clue if the version of IOS i found is even the right one.) The download goes for a few minutes and then mysteriously times out. The only error message I can find is the tftp server reporting that "the peer stopped responding".

-Strike 2.5: Ever since I installed the usb to serial adapter driver (had to use an adapter because my laptop doesnt have a serial port), my laptop crashes periodically.

-Strike 3: A model 1841 router. Powers on and boots to IOS (appears to be version 12.3). ITS QUIET! I was able to do a factory reset and get started practicing the commands I learned from CBT Nuggets. Some of the commands dont match, but thats ok Im figuring it out(I assume some of the commands on a switch are different on a router?). I make several config changes and then reset the router to test them. The router reboots to the config wizard prompt. I assume I missed a step and I go through the commands again, reboot, config wizard. "copy run start", nothing saved. "write mem", nothing saved. I read an article that suggests to erase the nvram, no help. Now Im starting to take it personally.

-Strike 4: I discover Dynamips/Dynagen and am very excited. I cannot get any of the labs to function. "cannot connect to localhost" and "error loading topology file".

I start drinking and i make this post with the hope that someone will be able to wave their magic cisco wand over me and get any of this stuff working.

Thank you for your time.

(UPDATE 2-1-12/13:30PST) - "Strike 3" has been solved ("confreg") and now I have a working 1841 router. I also bought a 2950 switch on ebay and am currently connecting everything. I need to do more homework to figure what, if anything, can be done about the 2811 ("strike 2"). Im also going to look into gsn3 and packet tracer later today.

1. 3620 should have a standard iec power cable
3620's are rackable. Sure its not a 1720 ?
I suggest having a look in the lab pics thread
http://www.techexams.net/forums/ccna-ccent/15235-post-your-lab-pics-30.html
The 1700's have an iec lead on the plug pack. the plug pack to the router have a propriety connector.

2. you might need to delete then reformat the flash and then reinstall ios.
Could also try via xmodem but it will take a long time(up to a few hours).
Might want to also make sure the flash is properly installed.
Can get bounced out in shipping (not often but does happen).

2.5 what brand usb to serial adapter ?
Make sure you used the correct driver.

3. 1841's are nice, I want to get a couple more(have 1 so far).
I wouldn't use the config wizard. Set it up manually then save.
setup hostname, enable password, ethernet ip, serial ip, telnet password so can use telnet to login then save and reload.

exec
configure terminal
hostname blahblahblah
enable secret cisco
int FastEthernet 0/0
ip address 192.168.1.2 255.255.255.0
exit
int Serial 0/0
ip address 192.168.1.4 255.255.255.0
no shutdown
exit
line vty 0 4
password cisco
login
exit
exit (or cntrl z)
write m
copy running-config startup-config
reload

That should be enough to get you up and running

4. Get gsn3 its dynamips with a pretty front end
see CBT Nuggets Player

Relax and take it easy.
it can be a nice large learning curve so one step at a time and don't stress out.

Hey Alxx thanks for the response. For #1 I have since confirmed that its a 3620, and here is a pic of the power plug

http://wiki.nesevo.com/images/9/95/PWR-600-AC-RPS_1.jpg

For #2, Ill look for information on erasing the flash, and checking the physical condition. It would also be great to have an answer for "what exactly am i looking for if i have to reinstall IOS on a 2811 router?"

for #2.5, i got the latest/greatest driver from the manufacturer so i dont think i can do any better there.

for #3, I have gone through all the steps you recommend, everytime i restart the router, the config wizard pops up and all the changes i just made are long gone.

for #4, is gsn3 a newer better version of dynagen? ill watch that video and check it out. thanks again.

1. You probably have a 3620 rps which uses a separate dc power supply unit.
maybe sell it on ebay and use the cash to buy something more useful ?
or buy a standard 3620 AC psu and remove the rps connector

2.

3. Is a cf card installed ?
what does show version give ?

If you do the commands I gave you above. but don't reload do
show running config
are any of the parameters you entered in the running config ?
Do the same for startup-config

can you copy the config to your tftp server ?
copy running-config tftp
copy startup-config tftp
then view them using a text editor like textpad/notepad/context/vim etc

4. gsn3 is a front end to dynamips. tells you on their site Graphical Network Simulator - GNS3

what you could try is save your running config
copy running-config old-config

then either
erase startup-config
then reload

or
delete startup-config
del nvram:startup-config

then reload

should give you a blank config

if you need the old config just
copy old-config running-config
then check it then save

If you do the same commands what do you get ?

LayOffPayOff · January 2012

First off Alxx I just want to say thanks for all the info. I actually discovered the issue I was having, although I dont really understand it yet. When I did "show run" id get "Configuration register is 0x2142" at the bottom. I followed some instructions online and changed that number to "0x2102", and now the configs seem to be getting saved. Maybe you can help me understand what happened?

That config register setting makes it bypass the startup-configWhy Does My Router Lose Its Configuration During Reboot? - Cisco Systems

sh ver or show version gives the config register status

LayOffPayOff · January 2012

Thanks again for your help. I had a good sleep last night and im feeling ready to take another stab at this. Assuming things remain as they are, would the 1841 be sufficient for me to train for the CCENT/CCNA or do I need to try to find a different model? I notice that the CBT Nuggets are using a switch whereas I am using a router.

Thanks

MAC_Addy · January 2012

You'll probably want to get at least a 2950 switch.

fsanyee · January 2012

I think at least 2950C/G/T. There are a few feature what you cant use with standard 2950, like RSTP, MSTP or QoS.

LayOffPayOff · January 2012

Would this work?

if not, what would be the best bang for my limited unemployment buck?

MAC_Addy · January 2012

Yep, that'll work.

VAHokie56 · January 2012

wow...just use packet tracer dude Packet Tracer - Wikipedia, the free encyclopedia

that's all I used to study with for CCNA

Im pretty frustrated, I think I just need to vent. Hopefully some of you will be able to give me a shove in the right direction.

Last week I started watching CBT Nuggets for ICND1. Im about half way through and I decide I want to start getting some hands on experience. I was laid off in October, but before I left I told my manager I wanted to go for the CCNA and he gave me some hardware that had been retired. This is where where my headache begins.

-Strike 1: What appears to be a model 3620 router (no clear printed model number, i made a guess based on the s/n sticker). Unfortunately it doesn't use a standard power cable and I dont have the adapter. The thing looks pretty shabby, is it worth my while to get a plug for it?

-Strike 2: A model 2811 router. It powers on and Im able to access it using a console connection. It makes so much noise I want to jump out the window. It appears to only boot to "rommon" mode with the following error msg: "cannot determine the first file name on device "flash".
Following some directions I found online, I set up a tftp server and used "tftpdnld" to download a new copy of IOS to the router. (I have no clue if the version of IOS i found is even the right one.) The download goes for a few minutes and then mysteriously times out. The only error message I can find is the tftp server reporting that "the peer stopped responding".

-Strike 2.5: Ever since I installed the usb to serial adapter driver (had to use an adapter because my laptop doesnt have a serial port), my laptop crashes periodically.

-Strike 3: A model 1841 router. Powers on and boots to IOS (appears to be version 12.3). ITS QUIET! I was able to do a factory reset and get started practicing the commands I learned from CBT Nuggets. Some of the commands dont match, but thats ok Im figuring it out(I assume some of the commands on a switch are different on a router?). I make several config changes and then reset the router to test them. The router reboots to the config wizard prompt. I assume I missed a step and I go through the commands again, reboot, config wizard. "copy run start", nothing saved. "write mem", nothing saved. I read an article that suggests to erase the nvram, no help. Now Im starting to take it personally.

-Strike 4: I discover Dynamips/Dynagen and am very excited. I cannot get any of the labs to function. "cannot connect to localhost" and "error loading topology file".

I start drinking and i make this post with the hope that someone will be able to wave their magic cisco wand over me and get any of this stuff working.

Thank you for your time.

I have a stack of 2500 routers at home that have served me very well over the years. In fact Im working through their issues tonight. Its been in storage for almost 2 years but Im getting there. Its a good learning curve. Anything fancy in terms of features I use remote racks, but old gear can serve well for lots of practice. Be patient and take the pain with your gear. I have overcome many issues assembling my home lab the last four days because I have been through it before..it helps you in the datacentre too.

LayOffPayOff · January 2012

I bought the 2950. Ive never heard of packet tracer but ill look in to it today. again thanks for all your help, i was pretty frustrated yesterday but im back in the game today.

alxx · January 2012

packet tracer is cisco's simulator for switches and routers for learning.

1841 is perfectly fine for labbing on.A lot newer than what most people are using.
They are are very nice and quiet and will do you up to ccie with enough ram ,flash and wics.

stlsmoore · January 2012

Believe it or not you're gaining a lot of real world experience going through the frustrations you're going through. Trust me man I've been there both in my labs and in the real world, I feel your pain. Just recently I ran into issue #3 in my current CCNP: Voice lab on one of my 2821's. If nothing else you're learning things that the books isn't teaching you.

LayOffPayOff · January 2012

Yeah I understand that, I know ill be glad about it all when its over. My newest lesson is that a 2950 doesn't support SSH if the IOS is old. Time to learn how to do an update...

alxx · January 2012

At least with 2950's you can get the ios for free from cisco , unlike the routers where you need a support contract
Just register , create a login then browse Download Software - Cisco Systems
