Display Detailed Component Operational Information
You can display detailed operational information about certain router components.
This feature is available on all routing platforms except the M5/M10, M20, and M40
routing platforms.
Action To display detailed operational information about a component, use the following
CLI command:
user@host> show chassis component-name
The command output displays the temperature of the air passing by the
component, in degrees Centigrade and Fahrenheit. It displays the total percentage
of CPU, interrupt, heap space, and buffer space being used by the component
processor, including the total DRAM available to the component processor. The
command output displays the time when the component started running and how
long the component has been running. A short uptime can indicate a problem with
the component.
Table 19 lists the components for which you can display more detailed operational
status information.
