Enabling link-down port auto power-down

To save power, enable the link-down port auto power-down function on Ethernet interfaces. The switch
stops providing power to the interface if the interface is in the down state for a certain period of time
(depends on the specifications of the chip, and not configurable). In this case, the interface enters the
power save mode. When the interface goes up, the switch provides power to the interface.
To enable link-down port auto power-down on one or multiple Ethernet interfaces:

Required.
Required.
Optional.
By default, all Ethernet interfaces
in a port group are up. To bring
up all Ethernet interfaces shut
down manually in a port group,
use the undo shutdown command
in port group view.
Optional.
By default, the device allows
jumbo frames within 10,000
bytes to pass through all Layer 2
Ethernet interfaces.
Remarks
—
Use either command.
Configured in Ethernet interface
view, the setting takes effect on
the interface only.
Configured in port group view,
the setting takes effect on all ports
in the port group.
Required.
Disabled by default.
