I've utilized Cisco Catalyst Switches on a DNA center. I've also used it for many solutions, e.g. in universities, telecom companies, and other commercial institutions.
I've implemented many solutions that contain Cisco Catalyst Switches, call switches, abbreviation switches, and access switches on Cisco design solutions. I worked on a network that contained more than 100 Cisco Catalyst Switches in some of the universities.
I use Cisco Catalyst Switches and I implement most of the technology with that content in IOS.
I like Cisco Catalyst Switches because most of the time, we can do what we want with the product. Cisco has good guidelines that enable us to implement anything, so we can have a multiple ability product on most of the network equipment worldwide.
Cisco has communities or forums that help us implement more complicated areas in terms of network, so in addition, Cisco is not just a network equipment company, because they provide us most of the solutions, development, protocols, and new technologies, more than any other company in the world.
I also like the availability of Cisco Catalyst Switches, including scalability and reliability. You can find all these in this product.
