Run a System Baseline for Environmental Resources
Step 7 Use the show environment command to display an overview of switch health.
It is important to monitor environmental resource values because something as small as a fan failure can
lead to a serious hardware problem. If your switches provide Power Over Ethernet (POE), then the show
environment command will also provide a view into the power supplies and if they are performing as
expected.
Step 8 If your switches are in a stack, run the show environment stack command to view all of the
environmental outputs stack wide.
Although some of settings are adjustable, we recommend leaving the settings with their default values.
