Even though the settings are made on the port group, they are saved on an interface basis rather than on
a port group basis. You can only view the settings in the view of each interface by use the display
current-configuration or display this command.

Enabling the auto power-down function on an Ethernet
interface
To save power, enable the auto power-down function on Ethernet interfaces. With this function, the
system automatically stops supplying power to an interface if the interface is in the down state for a
certain period of time (which depends on the chip specifications and is not configurable). The interface
enters the power save mode. When the interface goes up, the system supplies power to the interface and
the interface enters its normal state.

Configuring storm suppression
You can use the storm suppression function to limit the size of a particular type of traffic (broadcast,
multicast, or unknown unicast traffic) as a whole globally in system view or on a per-interface basis in
Ethernet interface view or port group view.
• In system view, you set the maximum size of broadcast, multicast, or unknown unicast traffic allowed
to pass through the system as a whole. When the sum of broadcast, multicast, or unknown unicast
traffic arriving on all interfaces of the system exceeds this threshold, the system discards packets until
the traffic drops below this threshold.
• In interface or port group view, you set the maximum size of broadcast, multicast or unknown
unicast traffic allowed to pass through an interface or each interface in a port group. When the
broadcast, multicast, or unknown unicast traffic on the interface exceeds this threshold, the system
discards packets until the traffic drops below this threshold.
