I'm confused about Cisco IOS, and I have some question about that.
Cisco IOS is used in routers and other devices.
Is it possible to write code (like PHP) for that?
If it's possible, what language can I use?
The thing that confuses me is not how to work with Cisco IOS; it's about whether I can develop and change my router or other devices according to what I need for the network or not?
