An [Acronym] for __I__nternetworking OperatingSystem.

Written by [Cisco] for use in their networking devices, such as routers. Purportedly the most ported OperatingSystem ever, since it gets ported to almost all devices [Cisco] develop internally. However, it is not ported generally to devices only sold with a Cisco label, but actually developed at subcontractors or acquired companies.

! A selection of Cisco devices ''not'' running IOS

Any device labeled [Linksys | http://www.linksys.com] by CiscoSystems:

    Some of these devices (most famously the [WRT54G]) run a version of Linux,
    for which Linksys has made the source code available on their website.
    There was a lot of controversy about this a while back, because initially they did not release the source.
    Other devices run custom firmwares as far as I know.

Cisco 7xx:

    A Combinet product that was relabelled when Cisco acquired the company.
    Runs Combinet OS (yuck). It is no longer available and has been replaced by the Cisco 8xx.

Cisco Catalyst 19xx:

    Menu Driven. The enhanced edition runs a watered down version of IOS.

Cisco Catalyst 30xx:

    Menu Driven.

Cisco Catalyst 2926:

    Runs on CatOS. The other 29xx XL switches are different and run on IOS.

Cisco Catalyst 50xx and 55xx:

    Runs on CatOS. The Route Switch Modules run on IOS.

Older Cisco Catalyst 4000 and 6500 models:

    You used to have a choice of IOS or CatOS at install time.
    Earlier models had Route Switch Feature Cards that ran on IOS as a separate entity.

Earlier versions of Cisco Aironet software on the 340 and 350 series:

    Some weird Menu Driven thing via terminal (yuck), but does have a good web configuration interface.
    Cisco have now released IOS for the 350 series units.
    The newer Cisco Aironet devices run on IOS (1200s, etc).

CiscoPix:

    Runs an OS that started as an embedded version of [BSD]:

    > Cisco PIX Operating System (OS);
    > a proprietary, hardened system that eliminates security holes and performance-degrading overhead
    > typically found in general-purpose operating environments.

    The environment is IOS-like, though the IOS FireWall commands and the PIX FireWall commands are completely different.
