Hi

native IOS means the ios which is developed by cisco for its devices.

catos i think it was incorporated from catalyst company.it is solely for layer 2 operations.

hybrid this is for catos on u r sup and ios on u r MSFC.

Thanks

Hi Chirag,

There are only 2 kinds of mode which CAT6500 support.

HYBRID MODE & NATIVE MODE

In Hybrid mode you have 2 images one is CATOS on sup and IOS on MSFC and you need to configure switch on CATOS and MSFC on IOS.

In Native IOS mode there is a single image for sup and msfc residing on sup engine and with single interface you have to configure msfc as well as switch.

Hi Chirag ,

The combination of CatOS on the Supervisor Engine and Cisco IOS Software on the MSFC is

referred to as the "hybrid" OS. The hybrid model operates as you know based on two

operating images, two configurations, and two command lines; one for each CatOS and Cisco

IOS Software.

Cisco IOS Software for he Supervisor Engine on the Catalyst 6500 Series (also known as

"Native" model) provides a single Cisco IOS image, configuration, and command line to

support all Layer 2, 3, and 4 functionality on the switch. Cisco IOS has historically been

a Layer 3 operating system on routing platforms, and when installed on the Supervisor Engine of a Catalyst 6500 has expanded these capabilities to include true Layer 2 functionality as well.

If you're thinking about a conversion from Cisco IOS to CatOS we must to be sure new

Hybrid OS be capable to support all modules/features you've or you'd like to obtain.
