Using CLI Commands to Monitor your Environment

Use the show environment CLI command to monitor the system. This section gives a basic overview of
the command and keywords you will need.
Enter the show environment [alarm | status | temperature] command to display system status

System Alarms

The system has two types of alarms: major and minor. A major alarm indicates a critical problem that
could lead to system shutdown. A minor alarm is informational—it alerts you to a problem that could
turn critical if corrective action is not taken.
When the system issues an alarm (major or minor) that indicates an over-temperature condition, the
switch does not cancel the alarm nor take any action (such as module reset or shutdown) for five minutes.
If the temperature falls 5 degrees Celsius below the alarm threshold during this period, the alarm is
canceled.
An LED on the supervisor indicates if an alarm has been issued. See
Refer to the Catalyst 4500 Series Switch Module Installation Guide for information on LEDs, including
Note
the startup behavior of the supervisor engine system LED.
