Cisco 1801 Router Configuration

[cpressland2]

Hey guys what's up?

So a friend of mine that runs a games business just upgraded their networking hardware and was going to chuck this 'Cisco 1801 Router' in the trash, So I decided to take it off his hands for a few bob. Anyway, It occurred to me after buying the router that I have NO IDEA how to actually use one.

Could somebody guide me through resetting the router back to factory settings. Right down to the basics, like, what ethernet goes in what port. I know it's functional because my mate was using it up until this morning.

Can somebody help?

Thanks

Just google around for the basic Cisco IOS commands. but basically you want to erase the startup config. Assuming you have the current login information access privileged exec mode.

If not, google Cisco 1801 password recovery for a guide on resetting the password.

Oh right, it's the Cisco 1801, first off you'll need a cauldron, two chicken legs, fine dust made out the skulls of beetles, a dagger, candles...

Oh, you meant just resetting it? Not configure it? Oh well, put in a console cable or whatever, SSH/Telnet into it, login and use the reset function, perhaps it was the delete startup-config? Hmmmm, I'll have to consult my black magics and voodoo scriptures again.

That's kinda how you feel after taking CCNA certification, I know myself.

connect to the console port with a rollover cable

enable [enter]

(enter priv exec mode password)

erase startup-config [enter]

reload [enter]

that should do it. you'll probably be presented with setup mode once it reboots...

Yeah i've been trying that for a while, I've yet to actually work out HOW to access the router at all. It's not like a normal device where I just 192.168.0.1 and use a web interface. I can't even work out which ethernet port to plug the cable to my PC into.

[MuffloN]

Use a SSH/Telnet client such as Putty http://www.putty.org/ to connect to it via anything else than the rollover cable.

[cpressland2]

Okay, so the plot thickens. When I plug an ethernet cable into any port on the router, no status lights are coming on and 'ipconfig' just shows as 'Media Disconnected'

[Sophism]

You need to use a console cable (rollover cable) and connect to the console port on the router.

Configure hyperterminal as shown here: http://www.cisco.com/en/US/tech/tk801/tk36...080094465.shtml

[cpressland2]

Okay... but I don't have that 'Console' Port on either the router or my PC, just ethernet.

[Sophism]

Thats because one end of a console cable connects to the serial port on your computer. The other connects to the COnsole port on the 1801.

[cpressland2]

D'oh, I don't actually have a serial port.

DAMN YOU CISCO!

Time to find a machine with one.

[Sophism]

Or just grab a USB to Serial cable. Thats what I use.

Two cables to do the job of ONE Ethernet cable... My god, why do people buy these routers? Why did I buy it? What was I thinking? In future, AirPort Extreme's all the way :D

lol, an Ethernet cable and a Console cable are completely different. But with your apparent limited experience with networking I would recommend an Consumer Router as well.

Don't get me wrong, I'm going to be using my AirPort Extreme anyway, but it seamed like a good idea to grab this because it was cheep and learn something in the process. I got fired a few weeks ago, not many jobs about, need to keep the old brain active while I'm job hunting.

Thanks for all your help dude, I'll revive this thread when the cables arrive.

Read up on some Cisco command references while waiting for the cables. Seriously, even if you know the cmd prompt like the back of your hands, it's nothing compared to the cisco command set :p

[offroadaaron]

OH GOWD this is funny! Good luck to you I say, you'll need to know completely how NAT/PAT works if you want it for the internet, you'll need to know ACL's and a crap load more.

Asking questions on here will get you nowhere unless they're very specific questions.

cpressland,

Dude! you are better off with some other router. Cisco is for professionals thats why the have Linksys offering for general consumers.

You will be pulling your head apart by the time you reach wireless configuration.

[cpressland2]

I don't think you guys understand WHY I bought the router, it was to learn something new, I already have an Apple AirPort Extreme that I use for all my normal networking.

After reading all the manuals and buying the cables I've managed to get the router working and fully functional. It's not actually far different from Linux networking when you get right down to it, it's just getting yourself into the right mindset.

It's not that hard... I learned to configure both a Cisco 2600 and an ASA 5505 in less than a week.

Hard or not is relative. I bet you'd learn to configure a standard router in less than an hour.

So, 5 days is, um, at least 10 times longer :p

LOL you'd configure it but you'd have no idea of what you're actually doing, you'd be googling everything and taking other peoples configurations.
