View source for IOS vs. CatOS: Basic Configuration

==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 2960 running IOS and a Catalyst 4006 running CatOS.

== Commands ==
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''


Configuration modes entered in (config-t):

(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


Commands entered in CatOS are committed to NVRAM instantaneously.

In CatOS there are 2 configuration modes. User mode and Priviledged mode (enable)

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