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'll be comparing two operating systems on a Catalyst 2900XL (CatOS) and a Catalyst 2960 (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.Vyatta2.JPG

Troubleshooting

In this section we tell you the commands to do all the fun stuff you are required to prove that your network is vastly superior to other networks.Mostly all done in the operational mode on Vyatta!
