IOS vs. CatOS: Basic Configuration

[[File:]]

CatOS

CatOS is the operating system used on Cisco's Catalyst switches before changing over to IOS. Before purchasing the technology from Crescendo in 1993, CatOS was called XDI. CatOS is a Unix-like operating system for many legacy Cisco switches. CatOS runs on the following switch series: 1200, 4000, 4500, 5000, 5500, 6000 and 6500. Some of the high end switches such as the Catalyst 6500 series still run CatOS.

On this page we will be comparing two switches; a Catalyst 4006 running CatOS and a Catalyst 2960 running IOS.

Commands

Commands entered in CatOS are committed to NVRAM instantaneously. In IOS, the user is required to issue a command to save to NVRAM.
