Configuring the savepower port-low-pwr option
The port-low-pwr option puts
all the ports on the switch into auto low power mode if they are not
linked.
Syntax:
When a link is detected, the ports return to normal power mode.
The no form of the command
puts the ports into normal power mode.
To display the status of the power-down feature,
use the show savepower portlow-pwr command. The
output shows if the feature is enabled or not enabled.
