Reporting Functions - Cisco Router 7204 Installation And Configuration Manual

Functional Overview

Reporting Functions

The Cisco 7204 displays warning messages on the console if chassis interface-monitored parameters
exceed a defined 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.
Refer to the Cisco 7200 VXR Installation and Configuration Guide publication for sample outputs of the
Note
show environment, show environment all, show environment last, and show environment table
commands from a Cisco 7200 VXR router that has an installed NPE-300. The Cisco 7204 does not
support the NPE-300.
Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature
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 other device.
The show environment command display reports the current environmental status of the system. 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 env
All measured values are normal
If the environmental status is not normal, the system reports the worst-case status level. Following is an
example overvoltage warning:
Router# show env
Warning: +3.45 V measured at +3.83 V
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 env last command:
Router# show env last
