CatOS/IOS Hybrids

CatOS/IOS Hybrids
The native operating system on the two platforms has always been CatOS, with the familiar set,
show, and clear commands used for almost all control aspects. The introduction of routing and layer 3 switching features on a separate module created the concept of two operating systems on
a single switch.
By using an internal Telnet connection, or a separate console port on the front of the introduced
module, access is gained to the IOS-based routing engine. The Catalyst 4000 4232-L3
module and the Catalyst 6000 Multilayer Switch Feature Card 1 (MSFC 1) and 2 (MSFC 2) fall
into this category.
