Datasheet

ASF SMBus Messages

The RTL8111E supports an SMBus interface that is capable of operating in master or slave mode (see the

SMBus 2.0 and ASF 2.0 specifications for more details about ASF SMBus Messages).

The RTL8111E’s ASF SMBus Messages are listed below:

• SMBus ARP Messages

The RTL8111E gets an SMBus Address from system firmware.

• ASF-Sensor Poll Messages (Get Event Status and Get Event Data)

The RTL8111E monitors the system state through Get Event Status and Get Event Data messages,

which poll ASF-sensors for individual events and present event status. The RTL8111E sends Platform

Event Trap (PET) alerts to the management console when it observes abnormal events.

• Legacy Sensor Device Poll Message

The RTL8111E monitors 8 sets of legacy sensors in the motherboard.

• Start Watchdog Timer

The system firmware starts the RTL8111E’s watchdog timer with a start watchdog timer message. If

the watchdog timer times out, the RTL8111E will send a PET alert.

• Stop Watchdog Timer

The system firmware stops the RTL8111E’s watchdog timer with a stop watchdog timer message.

• Push Alert Messages (Message with/without retransmission)

This message is used when the system firmware and sensors notify the RTL8111E to send a PET alert.

• Set System State Message

This message is used by the managed client’s firmware to record the client’s current System State into

the RTL8111E.

• Device Type Poll Message

Allows a SMBus master to further determine the characteristics of a SMBus 2.0 device that responds

to an ARP cycle with the ASF bit of its interface byte set to 1.

• Remote-Control Device Action Message

The RTL8111E forces a remote control action to the managed client via a Remote-Control Device

Action message.

• Boot Option Messages

This message uses the SMBus Block Read Protocol. The managed client’s firmware uses this message

to retrieve the options sent over the network to the RTL8111E via the RMCP commands: Reset (10h),

Power-up (11h), and Power Cycle Reset (13h).
