Re: 6500 Native Software Architecture - RP and SP versions of co
There is no seperate image for sup and msfc when you are running Native IOS. There is onle single integrated image.
Native mode mandates that both CPUs (SP and RP) run the full Cisco IOS Software operating system. There is no hidden Catalyst software running in the switch and the executable images used by both CPUs run the complete IOS kernel.
Native IOS Software requires the single image to be present on a device local to the sup because it is a bundled image for two processors and the SP boots first.
In Native IOS Software, both processors (the SP and RP) load the Cisco IOS Software. Two processors working together yield two ROMMONs and two bootflash devices. First, the SP boots to ROMMON and loads its portion of the Cisco IOS Software. When the SP is booted, the software control is passed to the RP so that the second processor can successfully boot. From a console perspective, the RJ-45 console port on the sup initially shows information from the SP. During the boot cycle for the Cisco Catalyst 6500 with the Cisco IOS Software, control is passed to RP CPU.
After this point the Route Processor controls the system. From the software perspective, the RP acts as the primary CPU and the SP acts as the secondary CPU. This is transparent to the user, all configuration commands are entered directly through the Route Processor CPU in Cisco IOS Software. Commands entered that affect the SP functionality are passed internally from the RP to the SP.
