Resolution
Catalyst 6000 series switches have a variety of modules, such as Supervisor, Multilayer Switch Feature Card (MSFC) and Policy Feature Card (PFC). To determine the hardware configuration of a Catalyst 6000 switch, issue the show version and show module commands in Command Line Interface (CLI). Some of the details can be verified physically.
