Reporting Functions

The Cisco 7200 VXR routers display warning messages on the console if chassis interface-monitored
parameters exceed a desired threshold. You can also retrieve and display environmental status reports
with the show environment, show environment all, show environment last, and show environment
table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief
description of each of these commands follows.
To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature
Caution
conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate
clearance around the sides of the chassis so that cooling air can flow through the chassis interior
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.
The show environment command displays reports of the current environmental system status. The
report displays parameters that are out of the normal values. No parameters are displayed if the system
status is normal. The example that follows shows the display for a system in which all monitored
parameters are within normal range:
Router# show environment
All measured values are normal
If the environmental status is not normal, the system reports the worst-case status level. Following is a
sample overvoltage warning:
Router# show environment
