RTL8111E

INTEGRATED GIGABIT ETHERNET CONTROLLER FOR PCI EXPRESS APPLICATIONS

Realtek Semiconductor 

RTL8111E

Datasheet

6.9.2. ASF (Alert Standard Format) 2.0 Support

Watchdog Timer

The RTL8111E supports two sets of start/stop watchdog timer. One is a software watchdog timer. The

other is a firmware watchdog timer counter. The system BIOS supports an SMBus interface running

SMBus Messages. The system initiating a ‘power on’ state enables the firmware watchdog timer of the

RTL8111E.

ARP Ethernet

The RTL8111E supports auto-response ARP Ethernet packets in an OS-absent environment.

System Heartbeat and Alert PET

The RTL8111E supports system heartbeat and Platform Event Trap (PET) Alert packets. System

heartbeat is a periodic message sent by the managed client indicating its presence to the management

console. A PET alert is an alert message regarding environment, system firmware, and OS events sent by

the managed client to the management console.

ASF EEPROM-Less Operation (RTL8111E-VC Only)

The RTL8111E-VC supports the ASF EEPROM-Less option.

Refer to the RTL8111E_EEPROM-Less_App_Note for details.

RMCP and Remote Control

The RTL8111E supports RMCP messages and remote control packets.

• RMCP Messages

ƒ Presence of ping/pong packets (80h/40h)

Used to identify the presence of an ASF-RMCP-aware managed client on the network.

ƒ System state request/response packet (81h/41h)

Used to identify the state of the managed client.

ƒ Capability request/response (82h/42h)

Used to identify the client system’s ASF capability.

ƒ Open session request/response (83h/43h)

Used to establish a protected session between the management console and the managed client.

ƒ Close session request/response (84h/44h)

Used to close a protected session.

• Support for four sets of remote control actions

ƒ Reset (10h), Power on (11h), Power off (12h), Power cycle reset (13h) (Refer to the ASF 2.0

specifications for more details)
