Environmental Monitoring and Reporting Functions
If the environmental status is not normal, the system reports the worst-case status level. Following is a
sample overvoltage warning:
Router# show environment
Warning: +3.3 V measured at +3.41 V
The show environment last command retrieves and displays the NVRAM log, which provides a record
of environmental status readings. Air temperature is measured and displayed, and the voltage supplied
by the power supply is also displayed.
Following is sample output of the show environment last command:
Router# show environment last
chassis core
chassis inlet
chassis outlet 1
chassis outlet 2
+2.5 V
+3.3 V
+5.15 V
+12.3 V
+12.3 V
-12.5 V
The show environment table command displays the temperature and voltage thresholds for each
temperature sensor and for each monitored status level, which are related to those thresholds listed in
Table 6-1
Following is sample output of the show environment table command:
Router# show environment table

Temperature ranges and values are subject to change.
Note
The show environment all command displays an extended report that includes temperature readings and
voltage readings.
