View source for IOS vs. CatOS: Basic Configuration

==IOS==
[[File:Cat2960.jpg|right]]

IOS (Internetwork Operating System) is the operating system primarily used for the majority of Cisco's current equipment, including Routers and Switches.

IOS uses different configuration modes, depending on what your currently configuring. For example - if you wanted to turn a port on in IOS, you would first need to be in priviledged exec -> global configuration -> and move into interface configuration, then issue the ''no shutdown'' command.

In IOS, the user is required to issue a command to save to NVRAM.

==CatOS==
[[File:Cat4006.jpg|right]]

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.

User mode is used for system monitoring. Priviledged (enable) mode is used to change all system configurations. All configurations in CatOS are done by a ''set'' command sequence.

Commands entered in CatOS are committed to NVRAM instantaneously.

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