Devices can be wakened via the network usingmagic packets. A magic packet contains the MAC addresses of the devices that are to be wakened. In order for a device to be wakened, it must be in either S3 (suspend to RAM – STR), S4 (suspend-to-disk – STD) or S5 (soft-off) mode. In the IGEL Universal Management Suite (UMS)administration, you can specify the network addresses to which the magic packets are sent.

For scenarios where the UMS is outside the devices' network and broadcast packets from the WAN are not allowed, you can define one or more Linux devices as a Wake-On-LAN (WoL) proxy.

All defined subnets

Include PageENLITEUMSP:_Icon_aktiviert.pngENLITEUMSP:_Icon_aktiviert.png☑ The magic packet is sent to the network addresses of all subnets that are defined for theUMS.  Include PageENLITEUMSP:_Icon_deaktiviert.pngENLITEUMSP:_Icon_deaktiviert.png

☐ The magic packet is not sent to the network addresses of all subnets that are defined for theUMS. (Default)

To add a subnet, proceed as follows:

1. Enable All defined subnets.
   

2. Click

...

1. Image Added in the area below All defined subnets.
   The Define subnets dialog is displayed.
   

2. In the Subnet field, enter the network address of the subnet.
   

3. Under CIDR (Classless Inter-Domain Routing), select the suitable suffix for the network mask.

   Info

   Values between 8 and 28 are appropriate. Example 1: The network address 10.43.8.0 with the suffix 24 corresponds to the CIDR notation 10.43.8.0/24 with the network mask 255.255.255.0. This network corresponds to a Class C network. The addresses that can be used by hosts lie between 10.43.8.1 and 10.43.8.254. Example 2: The network address 10.43.8.64 with the suffix 28 corresponds to the CIDR notation 10.43.8.64/28 with the network mask 255.255.255.240. The addresses that can be used by hosts lie between 10.43.8.65 and 10.43.8.78.

Network address of last known IP address

Include PageENLITEUMSP:_Icon_aktiviert.pngENLITEUMSP:_Icon_aktiviert.png☑ The magic packet is sent to the network address of the network in which the last known IP address of the device is located. In order for this network address to be determined, you will need to specify a network mask for each of the possible networks.

☐ The magic packet is not sent to the network address of the network in which the last known IP address of the device is located. (Default)

To add a network mask, proceed as follows:

Dedicated Wake On LAN Proxies

Include PageENLITEUMSP:_Icon_aktiviert.pngENLITEUMSP:_Icon_aktiviert.png☑ The magic packet is sent to the devices defined as Wake-On-LAN proxies. Each Wake-On-LAN proxy will send the magic packets as a broadcast within the network in which it is located.

Include PageENLITEUMSP:_Icon_deaktiviert.pngENLITEUMSP:_Icon_deaktiviert.png☐ Themagic packet is not be sent to the devices defined as Wake-On-LAN proxies.

To define one or more devices as Wake-On-LAN proxies, proceed as follows:

1. Click on

...

1. Image Added in the area below Dedicated Wake On LAN Proxies.
   The Edit Wake On LAN Proxies dialog will open.
   

2. Highlight the desired device in the left-hand column.
   

3. Click on

...

1. Image Added to select the device.
   

2. Click on OK.
   The device will now function as a Wake-On-LAN proxy.

To undo the configuration as a Wake-On-LAN proxy, proceed as follows:

1. Click on

...

1. Image Added in the area below Dedicated Wake On LAN Proxies.
   The Edit Wake On LAN proxies dialog will open.
   

2. Highlight the desired device in the right-hand column.
   

3. Click on

...

1. Image Added to deselect the device.
   

2. Click on OK.
   The device will no longer be configured as a Wake-On-LAN proxy as soon as the setting is sent to the device.
