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
Sub-configuration modes entered through Global Configuration Mode:
(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.
| 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 |
| Turn off ports | (config-if)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-if)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-t) | (enable)set trunk mod_num/port_num [on/off/desirable/auto/nonegotiate] [vlan_range] [isl/dot1q/dot10/lane/negotiate] |
| Clear Trunking | (config-t) | (enable)clear trunk mod/port vlan range |
| Delete files from Flash Device | (enable)delete bootflash:filename.cfg | |
| Crypto Key rsa | (config-t) | (enable)set crypto key rsa 1004 |
| Spanning Tree | (config-t) | (enable)set spantree enable all |
