Hi

I think the question is, difference between IOS and CATOS, the last one was used on Cisco switches a long time ago and the sintax is different, the following link could be useful to know the difference between these operating systems:

"Cisco IOS" is the OS that runs on some of Cisco's routers (e.g. ISR 4K) unless it's being used generically, than it's one of the various IOS variants.

"Cisco Catalyst IOS" is the OS that runs on the (older) Cisco Catalyst series of L3 switches. For example, the IOS on a 6880.

Cisco has other IOS variants, such a IOS-XE (e.g. Catalyst 4K) and IOS-XR (e.g. ASR 9K).

Hi

As Deepak mentioned, All the Cisco 2960 models use IOS. Now switches like 2940XL were using Catos.
