I need to know how to program these routers for school, but I need to exercise at home. Are there simulators for the console interface, for learning purposes? I took a look at eBay to get one, but they were quire out-of-budget ;-).

Thank you for your help!

Does your school not give you access to a lab? – mfinni May 25 '11 at 16:13
ofcourse, but not during the exam preparation week, in which I am atm. – friedkiwi May 25 '11 at 17:31

I highly recommend the GNS3 (graphical network simulation) tool.

It's a collection of several applications that each do their own part to make things work.

  • Dynamips, the core program that allows Cisco IOS emulation.
  • Dynagen, a text-based front-end for Dynamips.
  • Qemu, a generic and open source machine emulator and virtualizer.

The caveat here is that you need a copy of the IOS image you intend to run. Suffice to say, you generally need a smartnet contract or CCNx login on Cisco site to obtain it. With a little searching though, you'll likely find it.

It's been a while since I fired up GNS3 so I can't say with 100% certainly that the 1800 model was supported. However many routers are, and the functionality for command sets would likely be good enough if the 1800 isn't in there.

ISR (1800-2800-3800) are not and will not be supported by dynamips. – petrus Jun 13 '11 at 22:22

I used this in the past, and it is free. It does not specifically say the 1800, but it may suit your needs.

I don't know about 1800-series routers, but there is software that emulates a number of routers - may be worth looking at. It even has front-end software that makes it less hideous to use.

An 1841 series router is simulated in Cisco Packet Tracer version 5.1 which provides quite an adequate representation of IOS especially for training purposes up to CCNA level.

I can vouch for Packet Tracer aswell! Using it for simulating changes in a very large network. Worth a shot! – xstnc Aug 18 '11 at 6:57
