Enabling The Auto Power-Down Function On An Ethernet Interface; Configuring Jumbo Frame Support - HP A5120 EI Series Configuration Manual

To do...
Enter system view
Enter Ethernet interface view
Set the statistics polling interval on
the Ethernet interface
To display the interface statistics collected in the last polling interval, use the display interface command.
To clear interface statistics, use the reset counters interface command.

Enabling the auto power-down function on an Ethernet interface

To save power, enable the auto power-down function on Ethernet interfaces. An interface enters the power
save mode if it has not received any packet for a certain period of time (this interval depends on the
specifications of the chip, and is not configurable). When a packet arrives later, the interface enters its
normal state.
Follow these steps to enable auto power-down on an Ethernet interface:

Configuring jumbo frame support

Ethernet frames longer than the standard Ethernet frame size (1536 bytes) are called "jumbo frames",
which are typical of file transfer.
 If you set an Ethernet interface to accept jumbo frames, it allows frames up to 9216 bytes to pass
through.
If you disable an Ethernet interface to accept jumbo frames, it allows frames up to 1536 bytes to

pass through.
Follow these steps to configure jumbo frame support in Ethernet interface view:
