I work for an IT reseller and we carry a few different types of hardware. I find myself in several scenario's where I have to guide clients to get copies of configs, recreate issues, check compatibility, etc. Unfortunately, I don't have access to all differetn makes and models of hardware that I work with in a sandbox or testing environment. I'd like to find a really good simulator that would simulate access to several different types of network hardware. Access to both GUI and CLI would be needed. If I had to only pick a few, it would be Cisco, HP. We also work with VMware, Microsoft products, Servers, Fortinet...the whole works...any suggestions for the most all-inclusive simulator out there that would allow this? If not all inclusive, multiple suggestions?
