Operating System Of Cisco Network Devices
I was thinking to write about DSL, VPN, ACLs and other configurations on cisco devices. But first things first, it’s important to know about the operating system of cisco network devices.
IOS (Internetworking Operating System) is the operating system that cisco devices use. IOS belongs to CLI (Command Line Interface) category of operating systems; this means that the administrator has to write commands in order to perform different tasks on the device. Note that some Catalyst network devices use the CATOS operating system, which is also a cisco software product and a CLI operating system.
In the other hand we can use a web interface for the configuration of our device.
Looking at the images below you can see the Cisco SDM (Security Device Manager) and the Catalyst 3550 Series Device Manager.
