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.
