• alarm - display only environment alarm information, this is the default display on 6500 series switches if no option is selected
• status - display status of power supplies, fan tray and chassis, this is the default display on 4500 series switches if no option is selected
• temperature - display detailed temperature information for chassis or all system components (dependent on platform)
• connector- display detailed power connector information for chassis and modules
• cooling - display fan tray status and type and module cooling requirements
