show odometer：
Description
Displays a counter for each component of a switch that shows how long it has been functioning since it was manufactured.
Usage Guidelines
The output from this command displays how long each individual component in the whole switch has been functioning since it is manufactured. This odometer counter will be kept in the EEPROM of each monitored component. This means that even when the component is plugged into different chassis, the
odometer counter will be available in the new switch chassis.
