Wake On LAN Advanced Properties Dialog Box

Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2

Use the Wake On LAN Advanced Properties dialog box from the Site Properties: Wake On LAN tab to fine-tune how wake-up packets are sent from the site server when you have one or more of the following items enabled for Wake On LAN:

  • Software update deployments configured with a deadline

  • Mandatory software distribution advertisements

  • Mandatory task sequence advertisements

The Wake On LAN Advanced Properties dialog box contains the following elements that help you control the network bandwidth used by wake-up transmissions:

Retries
The number of times a wake-up packet will be sent to a target computer.

After a wake-up packet is sent to all computers targeted by a scheduled activity (a mandatory advertisement or software update deployment with a deadline), the transmission is paused for the Delay period. If this retry value is greater than 1, a second wake-up packet is then sent to the same computers and the process is repeated until the retry value is reached. The second and subsequent wake-up packets are sent whether or not any errors occur.

It is more likely that a computer will successfully wake up if it is sent a number of wake-up packets, rather than just one. However, if you set this value higher than computers need, network bandwidth and processing capabilities on network devices is consumed unnecessarily.

The default setting is 3 retries. Values can range from 1 to 5.

Delay
The amount of time in minutes that a wake-up transmission is paused between retries.

The default setting is a 1-minute delay. Values can range from 1 to 5 minutes.

Maximum
The maximum number of wake-up packets to be transmitted by the site server to the target computers before pausing for the Wait period.

The pause avoids potentially saturating the network for an extended period of time. At the end of the configured Wait period, the transmission of wake-up packets resumes for the remaining targeted computers until the Maximum value is reached again, and the process is repeated.

The default setting is 10000 wake-up packets. Values can range from 1000 to 99999 maximum packets.

Wait
The amount of time in seconds in between sending batches of wake-up packets to target computers.

The default setting is 10 seconds. Values can range from 0 seconds to 100 seconds.

Transmission Threads
The number of threads the site server uses when sending wake-up packets.

Increasing the number of threads increases the likelihood of making full use of available network bandwidth, particularly when the site server computer has multiple cores or processors. Increasing the number of threads might also produce a significant increase in CPU utilization.

The default setting is 3 transmission threads. Values can range from 1 to 9 threads.

Transmission Offset
The amount of time in minutes that wake-up packets will be sent prior to a scheduled activity that is enabled for Wake On LAN.

Set a value that is sufficiently in advance of the scheduled activity so that computers have completed startup, but not so far in advance that the computer returns to a sleep state before the scheduled activity.

The default setting is 3 minutes. Values can range from 1 to 60 minutes.

OK
Saves the changes, and exits the dialog box.

Cancel
Exits the dialog box without saving any changes.

Help
Opens the help topic for this dialog box.
