==CatOS==
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.

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.
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

IOS

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.

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.

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

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


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

Commands entered in CatOS are committed to NVRAM instantaneously.

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-int)no shutdown (enable)set port enable mod/port
Turn off ports (config-int)shutdown (enable)set port disable mod/port
Banner-MOTD (config-t)banner-motd # banner here # (enable)set banner motd # banner here #
Clear Banner (config-t) (enable)clear banner motd
System / Hostname (config)hostname name (enable)set system name name
Set Idle Logout time (config-t) (enable)set logout time (in minutes)
Bandwidth (config-int)bandwidth number in kb (enable)set port speed speed in megabits
Setting up a domain name for VTP (config-t)vtp domain domain-name (enable)set vtp domain domain-name
Enabling VLANS (config-t)vlan number (will put switch into sub-config mode, but the vlan will become active) (enable)set vlan number state active
VLAN names (config-vlan)name name (enable)set vlan vlan number name name
Delete VLANS (config-t)no vlan number (enable)clear vlan number
Enabling Trunking (config-int)switchport mode trunk (enable)set trunk mod_num/port_num [on/off/desirable/auto/nonegotiate] [vlan_range] [isl/dot1q/dot10/lane/negotiate]
Clear Trunking (config-int)no switchport mode trunk (enable)clear trunk mod/port vlan range
Delete files from Flash Device (enable)delete flash:filename (enable)delete bootflash:filename
Spanning-Tree (config-t)spanning-tree vlan (enable)set spantree enable all
