--wakeonlan
Valid Argument enable, disable, bootseq, addincard, onboard, enablewakeonwlan, lanorwlan,
lanwithpxeboot
Description
Defines the wake-on-LAN feature.
• enable — The system wake-on-LAN feature is enabled; either an onboard or an
add-in NIC can wake the system up.
• disable — The system does not respond to magic packets or other means of
wake-on-LAN. The NIC chip section that looks for packets will not be powered.
• addincard — Enables NICs, plugged into the special power connector, as the
source of any wake-on-LAN signal.
• onboard — The onboard NIC is enabled for wake-on-LAN.
• enablewakeonwlan — Enables wake-on-LAN for wireless.
• lanorwlan — On systems that have onboard LAN and wireless LAN hardware,
enables wake on either wired or wireless LAN.
• lanwithpxeboot — Enables the network controller and causes the system to
wake up and immediately boot to PXE when a wake packet is sent to the system
in the S4 or S5 state.
Example
C:\>cctk --wakeonlan=lanwithpxeboot
wakeonlan=lanwithpxeboot
--wakeonlanbootovrd
Valid Argument enable, disable
Description
Enables or disables the wake on LAN boot override feature.
• enable — When the system powers on due to a wake-on-LAN event, the NIC
boot-ROM is automatically given the highest boot priority, pre-pending the PXE
boot-ROM to the system current boot sequence. If the system powers on due to
some other event, this selection does not influence the boot sequence.
• disable — Disables the boot override feature and the system boot sequence is in
effect for all types of system power on.
Example
C:\>cctk --wakeonlanbootovrd=enable
wakeonlanbootovrd=enable
