Functional Overview
The show environment last command retrieves and displays the NVRAM log, which shows the reason
for the last system shutdown (if the shutdown was related to voltage or temperature) and the
environmental status at that time. Air temperature is measured and displayed, and the DC voltage
supplied by the power supply is also displayed.
Following is sample output of the show environment last command:
Router# show environment last
Temperature readings:
chassis inlet previously measured at 27C/80F
chassis outlet 1 previously measured at 31C/87F
chassis outlet 2 previously measured at 37C/98F
chassis outlet 3 previously measured at 45C/113F
Voltage readings:
+3.45 V previously measured at +3.51 V
+5.2 V
+12.2 V previously measured at +12.42 V
-12.2 V previously measured at -12.14 V
Reason for last shutdown:
power supply
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 1-10
