The Cisco Catalyst 6000 series can be a layer-2 or layer-3 switch (router). There are 3 elements to the Supervisor module (1A & 2) - there is the Switch Processor, the PFC (policy Feature Card) and the MSFC (Multilayer Switch Feature Card). When you run Hybrid Mode you run separate software on the Switch Processor (CatOS) and the MSFC (IOS), with Native Mode you run a single image that controls both bits of hardware - there is no separate configuration for both engines. The user interface is IOS but unlike Hybrid code where you create VLANs and assign ports to the VLANs you can configure each physical interface as a Routed Interface and configure an IP address on the physical port (interface gigabitethernet 1/1 etc). VLANs are obviously still a feature and you can assign physical ports to VLANs, but this is one feature you can't do with Hybrid Code.
There are pros and cons of both solutions but most people seem to sway towards Native Mode. Native mode is only available when you have the MSFC installed on the Supervisor.
