Possibly low level language or its own language. Its not TCL for sure.

But why do you want to know? What benefits that it gives in knowing it?

Unless of course you are applying for a job in Cisco IOS Development Team.

IOS is generally developed in C. Speaking as a computer science guy, I tell all students wanting to lear programming to learn C. Yeah, it may not be as sexy as Java or C#, but getting your hands dirty with memory management and point manipulation makes you appreciate higher level languages more.
