There are a lot of switches, routers, and firewalls out there that, although not the latest, are still quite functional. And they're available inexpensively or even free. Buying used gear is most often technically just as illegal as grabbing the images from some file sharing site because the licenses are not transferable.

Dec 21, 2015 - This tutorial guide you how to emulate CISCO ASA in GNS3. [1] Download CISCO ASA image for GNS3. Here is the link. Just a post about the basic config and options of Cisco IOS zone based firewall using the Topology below Grab the initial configs and GNS 3.net file [HERE]. From the initial configs all interfaces have connectivity to each other. First off lets configure the zones and assign each interface to a zone.

That said, I carefully reviewed the license for the software that makes my car work and it's not transferable either so in some cases buying a used car is just as illegal (technically -- no court would ever entertain that you did something illegal with regard to software licensing in buying a used car). I expect the automobile manufacturer's lawyer wasn't a software licensing specialist and used a lot of boiler plate text from somewhere else without actually realizing the real implications. Of course there are dozens of Cisco re-sellers that sell used gear and those that do it the official Cisco way (sending the equipment back to Cisco for official re-licensing and charging again for the licensing) are obviously at a serious pricing disadvantage. I don't know of any cases of Cisco taking legal action to enforce their intellectual property rights against a re-seller and I'd be very surprised if they took exception to someone using their software in a 'virtual' GNS3 environment. If the software images do come from anywhere other than the official Cisco software repository (including preinstalled on used gear) you really need to check the MD5 signature against the official Cisco version. There have been reports of compromised IOS images making the rounds.

Download jvc sxxsw6000 manual. I wonder what does harm and what does good from Cisco's perspective. Does Cisco come down hard on the little guy trying to get his CCNA? That little guy is going to pay for his CCNA (and maybe a CCNP) and chances are he'll be drinking at least some of the Cisco kool-aid for the rest of his networking life. I'll bet Cisco bank on getting more sales from 'on-boarding' Cisco acolytes than they would if they were seen to be harsh with people who, at the end of the day are likely to recommend and use MORE Cisco kit and not less. The same goes for the 'un-official' re-sellers. At the end of the day if a business (or whatever) buys a bit of Cisco gear, who is going to be making money?

Chances are Cisco are in for a 'windfall' somewhere along the line whether it's a licence/feature upgrade, a module or WIC purchase or (now that the business has taken the Cisco plunge) they buy new gear from an actual Cisco re-seller with all the bells and whistles. And lets be clear, I do not condone illegal file sharing of any kind but come on, lets elevate the thinking beyond the actual small print and live in the real world.

I firmly believe Cisco turns a blind eye to a lot of this 'grey market' activity in pursuit of the greater (for them) good. Doesn't do us Cisco engineers who need lab gear any harm either. All in all I think if Cisco were to start firing law suits across the globe to protect their IOS's (especially 'old' IOS's) would do them a great deal of harm indeed. 'Cisco even gives free ios updates you just have to write a email to tac with a show ver, then show them the vulnerability your facing and they want serial too to make Sure it's not stolen.

Cisco has to update their equipment if there is a vulnerability it says so on their site. I have done it many times!' Has anyone else been brave and done the above? Every single person even remotely resembling a networking professional that works with Cisco equipment has always said that your gray market switches and routers should never talk to the internet or they will 'phone home' and really bad things will happen.
