IOS provides a command-line interface with the set number of multiple-word instructions. This operating system is used to configure routing, switching, internetworking and other services enabled by a Cisco equipment. NOTE Previous generations of Cisco switches run CatOS, a legacy version of a CLI-based operating sytem. Below you can see how IOS looks like when a Cisco device is launched for the first time, using a 3745 router as an example: Cisco 3745 (R7000) processor (revision 2.0) with 249856K/12288K bytes of RAM. Processor board ID FTX0945W0MY \sR7000 CPU at 350MHz, Implementation 39, Rev 2.1, 256KB L2,...
