Working with Cisco Equipment

Recommended Posts

Hey, not sure if this should be elsewhere or here, so please move if required.

 

I have been lent a Cisco 800 Series router to have a play with as i'm curious and thinking about putting 2 in at work (long time away). So i was wondering if anyone could suggest or assist with how to go about setting the router up to be able to have a play with it?

 

Am looking for some simple to understand reading material or advice as my knowledge in this area is quite low.

 

Also, do the 800 Series have a web interface?

 

Cheers

stephen

I've had a look but trying to find it seems to be behind the "i've payed for support" door.

 

I have been able to get into the router though the serial port, but from there it's like code to me....

Yep that is right.

 

Is should plonk you at a terminal like so;

router>

 

Type;

router> ena

If it asks for a password you may be screwed unless you know it, you can always boot into terminal mode (more on that later if you need).

 

Otherwise it should now be like;

router#

So just run;

router# sh ver

Well this is wherew i am running into a little trouble. Every time i boot the router i get this:

--- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]:

But i can hit no, and it boots up. This is the result of SH VER

Thanks, busy working through it. how can i determine what the router ip is? as its factory reset, whats my best bet?

 

Also, do i need to specify to save before i turn the router off or it is automatic?

The answers to your questions are pretty broad if you've never used a Cisco router before.

 

I'd suggest starting with some "introduction to Cisco IOS" tutorials - Google can help there. If you're not willing to do a lot of reading on how to use IOS and secure the router for a business, I'd strongly recommend engaging an IT company with Cisco knowledge to do this for you. (though many of them are hopeless anyway)

 

To check its IP addresses (if any) issue the command 'show ip interface brief'.

 

Config saving isn't automatic. To save the config after you've made changes, use the command 'copy run start'.

Agreed that i will need to work through a lot of information if i want to set it up for the business. Right now i would just like to get into it to have a play with. I was wondering if anyone could assist with a basic setup guide to get the router working and online?

 

How can i reset it to factory defaults (again) to ensure none of my stuffing around has caused any problems.?

 

I have followed the guide on here, is this a good setup or can someone provide a more idiot proof version?

 

Edit: Well i seem to have been able to reset it, and once i walked through that guide again it worked. I think my fiddling might have blocked something beforehand.

 

Can anyone recommend any good "dummy" guides for me?

 

Thanks

So last night i thought i would update SDM on the router from 1.1 to 2.5. The update seemed to go well as i used the cisco software but now i cant seem to be able to get into the damn thing cia the web interface.

It just stays on the SDM launch page and doesnt seem to progress any further.

 

Is there a way that i can wipe the whole thing and start fresh back at 1.1?

The SDM is a java thing isn't it?

You can always try deleting the file from flash memory, but you will need the older file to reupload.

Well so i REALLY stuck my foot in it this time. I thought i would reload the SDM2.5. Following some article online it said to erase the webflash and "squeeze" the flash. Smart me erased the flash. So i am now thinking i might have bricked it....

 

I dont even get to the :router>: stage and am stuck at :rommon 1 >"

 

Can anyone help to reload the flash? i am assuming i need an IOS image but i cant seem to get it anywhere from the cisco site without paying.

 

this is what i get on the router boot.

Thanks garlic.

 

so with a bit of help from garlic, and a bit of trawling on the good old fashion interweb, i cam up with this. Hopefully it will help someone in the future as well.

 

I am pretty sure there is a better/easier way of doing this but this worked for me. The information is available on various websites and on the cisco site as well.

 

CISCO 837 Stuck at rommon> prompt.

1. download and setup tftp software. I used a program called TFTP32

2. You need a copy of the image somewhere, backup or other.

3. Next you need to restore the image to your router. In terminal, i typed the following

rommon 1 > IP_ADDRESS=192.168.0.1
rommon 2 > IP_SUBNET_MASK=255.255.255.0
rommon 3 > DEFAULT_GATEWAY=192.168.0.5
rommon 4 > TFTP_SERVER=192.168.0.20
rommon 5 > TFTP_FILE=[i]the-image-name[/i].bin
rommon 6 > tftpdnld -r

you may need to substitude the values to suit your netowkr/files

4. The router then should hopefully boot up into the normal cisco setup. once up and running you need to enter enable mode and type "copy tftp flash". Follow the onscreen prompts and it will re-copy the flash file accross to the device

5. Last, type "write" and "reload" and it should all boot nicely.

Also, for anyone who is having issues using SDM where it doesnt load the java part, it seems to be that it doesnt like the lates release. i download this and it worked fine LINK
