Determining the Current Operating System on a Cisco Catalyst 6500

The Cisco IOS command line for both the Cisco IOS portion of hybrid and Cisco IOS systems look identical. To

determine what operating system is running on the switch, you can use the show version command from the Cisco

IOS command line. To access the IOS (Layer 3) functionality in hybrid OS, enter session 15 or switch console from

the command line. The console is then turned over to the MSFC, and this is where both Cisco IOS and hybrid OS

systems look identical.

Additionally, you can determine the OS on the chassis by viewing the interfaces. For example, using show ip interface

brief command on the hybrid OS shows VLANs. The same command on Cisco IOS Software displays physical

interfaces (for example, gigabitethernet 1/1) as well as VLANs interfaces.

Cisco IOS and Hybrid OS Boot Process

The boot process in both the Cisco IOS and the hybrid operating system models is automatic and transparent to the

user. In the hybrid model, the boot processes are separate for both the switch and the route processors as they each

boot independent operating systems.

In Cisco IOS Software, the two processors (the SP and RP) each 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

processorcansuccessfullyboot.From a console perspective, the RJ-45 console port on theSupervisorEngineinitially

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 as shown in the following statement on the console:
