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.

Commands

Vyatta does not support short hand abbreviations of the commands like cisco routers do. You also have to use the commit command after every command for it to become in effect. Any command that uses a subnet mask in Vyatta uses the slash notation 192.168.0.0/24

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!

	Cisco Command	Vyatta Command
	Ping	Ping
	tracert	tracert
	show ip route	show route
	show int int	show interfaces ethernet ethx
	show ip ospf neighbor	show ospf4 neighbor
	(config)debug ip rip	show debug rip
	(config)debug ip opsf events	debug ospf event
	show run	(config)show running-config
	copy run start	(config)save filename
	erase start	(config)delete the load up file path
