All cisco routers run the same software and have the same user interface. Of course you can't do too much with one router. Read about Feature Sets to make sure you get what you want. you could think of them like Vista-Home vs Vista-most-expensive. all of them have a base set of features and the more expensive ones do more. For CCNA the base set is quite likely to be enough.Some 830 series routers can have a second "internal" routed ethernet port but this may require a fancy Feature Set. It is definately worth seeing the hardware but you can also use Dynamips, a free router emulator for PCs. One point about dynamips is that it needs a real Cisco Software image.

Continuing in the same thread... ....so I went ahead and bought myself a used 831, the idea is to learn while using it for my broadband connection. However, it seems that this one is not healthy. It is stuck in a constant reboot loop with a INSUFFICIENT MEMORY TO BOOT DEVICE message. (log below). As far as I gather there is a multitide of IOS versions in existence, and I am wondering if the version that my router is trying to start (and failing) is supported? What solution to this error message is possible, apart from screaming angrily at the seller?

Its possible that somebody removed/swapped out the RAM that was in the box for a lesser amount, or somebody forced something upon it that doesn't work. Easiest solution? Complain to the seller that they didn't provide a working router to you. The image you have doesn't boot, its DOA. >As far as I gather there is a multitide of IOS versions in existence, and >I am wondering if the version that my router is trying to start (and >failing) is supported? Its supported for some exent, but perhaps your hardware specs aren't quite up to what that specific image needs. >What solution to this error message is possible, apart from screaming >angrily at the seller? That will be far easiest for you. Officially, you can't get new/old IOS images without SmartNet on the box (which may not be able to get SmartNet maintenance on it any longer, don't know about them), but that being said, its fairly easy to search for the filenames on the Net.. >Cisco IOS Software, C831 Software (C831-K9O3SY6-M), Version 12.3(8)T1, >RELEASE SOFTWARE (fc3) Okay, so you have an 831, it is booting 12.3(8)T1.

Okay, down to business to find what you need out. Cisco FN says (http://cisco.com/go/fn) for the exact image you are running, c831-k9os3y6-mz.123-8.T1.bin, you need to have 48M of DRAM and 12M of Flash. Which you do. Thus, either the IOS flash image itself is bad, or the DRAM in the box is bad, and you are crashing when it tries to access the higher levels of memory, or you have a bad motherboard alltogether. Personally, I'd first go back to the reseller and tell them they sold you bad hardware. Most likely the item that is bad is the DRAM chip. IIRC, that particular model has RAM soldered both onto the motherboard, and in a SIMM slot. So you could swap out some of the RAM, but not all of them. The next most likely bad thing could be the Flash IOS image could be corrupt. You could try to find that file name again, and flash the box up with it. But, I'd bet it was bad DRAM first. Lastly, if the bad RAM is on the motherboard, or the motherboard is toast, its not worth getting this box fixed up (ie. I'm not sure you can get SmartNet maintenance on it any longer). I'd go back to the seller and complain they sold you bad hardware. The image you have should boot in the RAM that is reported, but its failing out, and most likely you will never get the router to boot with any special magic commands.

I have obtained a different release of the IOS (friend with a CCO account), and i managed to get the router working and operational. I think the seller has sold it due to him trying to get a wrong version on it. Seems to be working happily now, and SDM also recognizes it properly. Mucho thanks for your help. -- * has started to scramble (Stargate) |
