Overview
The Surveyor uses built-in selection criteria for selecting new proxies. This article explains how Surveyor elects Wake on WAN Proxies to help you determine which devices to set as preferred proxies or to never be proxies.
Information
Device Ranking for Proxy Selection
In the Administrator console, you can specify Wake on WAN proxy preference for devices in the device properties (right-click selected devices and choose Device Properties).
When the Surveyor server detects that it needs to select a new Wake on WAN proxy for a broadcast domain, it uses this preference setting along with other criteria to determine which device to select. It does so in the following order of preference:
- Devices with the Preferred Wake on WAN proxy setting of Preferred.
- Devices with a Preferred Wake on WAN proxy setting of Default if the device is not a laptop.
- Laptops with a Preferred Wake on WAN proxy setting of Default.
The server runs through a series of additional checks to determine whether the computer meets other requirements for relaying data packets. For example, it confirms that the device’s network card, IP address, and subnet mask are set properly for Wake on LAN within its broadcast domain.
NOTE: If a new device joins a broadcast domain, and it has a higher preference ranking than an existing proxy, Surveyor will un-assign the existing proxy and select the new device in its place.
Determining Which Devices to Set as Preferred Proxies
Wake on WAN proxies remains on at all times. Therefore, some devices are more appropriate than others to serve as proxies. For example, devices that need to be on 24/7 to serve critical functions are good candidates to set as preferred proxies.
On the other hand, laptops tend to be moved around frequently, so it is better to set as many laptops as you can to never be preferred proxies and leave the remaining laptops in the default setting.
Beyond these two suggestions, the best practice is to leave most devices with the Preferred Wake on WAN proxy setting of Default and allow Surveyor to use its built-in criteria to select new proxies as needed.
