Black Market Network Equipment? Oh yes, and something to watch out for.
It only recently came to my attention that this even existed. There is a growing problem of counterfeit, imitation, fake and the like of Cisco and other high end network equipment. When recently shopping around for a couple of Cisco boxes is when I was made aware of this problem through a couple of trusted used network hardware resellers.
There is an organization called UNEDA that has taken the lead on bringing attention to the problem using an alliance of more than 300 of the top used network equipment dealers worldwide. Check them out and be aware!
