Configuring Power-Saving Status; Configuring The Port Status Detection Timer - H3C S5500-HI Series Fundamentals Configuration Manual

When the power-saving function is enabled globally, all LEDs operate according to the
•
power-saving status, and all Ethernet interfaces are automatically enabled with the power-saving
function.
Follow these steps to enable the power-saving function:

Enable the power-saving
function

Configuring power-saving status

With the power-saving function enabled, the device might be in either of the following statuses:
• Sleeping status (sleep)—The device shuts down all LEDs except the SYS LED on the panel, and
automatically enables the power-saving function of all Ethernet interfaces.
Wake-up status (wake)—The device automatically enables the power-saving function of all Ethernet
•
interfaces but keeps the original operations of the LEDs.
The device supports the following ways to trigger power-saving status switching:
Automatic switching—When the device is in sleeping status, if data is being exchanged through the
•
console port or you press the Mode button, the device automatically switches to the wake-up status,
so that you can check the LED statuses. When the device is in wake-up status, if no data is being
exchanged on the console port for a period of time (defined by the save-power delay-timer
command) and you do not press the Mode button, the device automatically switches to the sleeping
status.
Manual switching—You can use the save-power mode command to manually configure the
•
power-saving status.

Configuring the port status detection timer

Some protocols might shut down ports under specific circumstances. For example, MSTP shuts down a
BPDU guard enabled port when the port receives a BPDU. Then, the device starts the detection timer. If
