About Environmental Monitoring
Environmental monitoring of chassis components provides early warning indications of possible
component failure. This warning helps you to ensure the safe and reliable operation of your system and
avoid network interruptions.
This section describes how to monitor critical system components so that you can identify and rapidly
correct hardware-related problems.
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 need.
Enter the show environment [alarm | status | temperature] command to display system status

Displaying Environment Conditions
Supervisor Engine 6-E, Supervisor Engine 6L-E, Supervisor Engine 7-E, and Supervisor Engine 7L-E
and their associated line cards support multiple temperature sensors per card. The environment condition
output includes the temperature reading from each sensor and the temperature thresholds for each sensor.
These line cards support three thresholds: warning, critical, and shutdown.
The following example illustrates how to display the environment condition on a
Supervisor Engine 6-E and Supervisor 6L-E. The thresholds appear within parentheses.
