Power-Saving Features
Configuring the Savepower port-low-pwr Option
The port-low-pwr option puts the slots into auto low power mode if they are
not linked. If a particular slot is specified, only that slot goes into auto low
power mode. Specifying all puts all the slots into auto low power mode.
The ports in low power mode periodically monitor to determine if the link has
become active. If a LAN cable is connected to one of the ports, that port will
come out of the low power mode state after approximately 2 seconds (the
monitor period) and enter into normal power mode. The remaining ports
continue to be in low power mode.
The no form of the command puts the specified slot into normal power mode.
Specifying all with the no form of the command puts all the slots into normal
power mode.
