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.
IOS configuration modes used below:
(enable) - Priviledged Exec mode. command: enable
(config-t) - Global Configuration mode. command: config terminal
(config-if) - Interface configuration mode. Switchports, EtherChannel groups, VLAN interfaces. command: interface interface"module/port". Example: interface fastethernet0/20
(config-vlan) - VLAN configuration mode. vlan "number"
(config-line) - Console, Auxillary, VTY. line "line-mode" "number". Example: line con 0

| IOS Command | CatOS Command | |
|---|---|---|
| Privileged | Enable | Enable |
| Interface | (config-t)interface int (which puts you into interface configuration mode) | (enable)set port command mod/port |
| Set Console Password | (config-line)password password | (enable)set password (you will be prompted to change password) |
| Turn on ports | (config-if)no shutdown | (enable)set port enable mod/port |
