The Administration Server polls the specified IP ranges using ICMP packets or the NBNS protocol and compiles a complete set of data on devices within those IP ranges. By default, this type of polling is disabled. It is not recommended to use this type of polling if you use Windows network polling and/or Active Directory polling.
Viewing and modifying the settings for IP range polling
To view and modify the settings for polling IP range groups:
In the console tree, in the Device discovery folder, select the IP ranges subfolder.
You can proceed from the Unassigned devices folder to the Device discovery folder by clicking Poll now.
If you want, in the IP ranges subfolder click Add subnet to add an IP range for polling, and then click OK.
Click Configure polling.
The IP ranges properties window opens. If you want, you can modify the settings of IP range polling:
This option is not selected by default. It is not recommended to use this type of polling if you use Windows network polling and/or Active Directory polling.
If the Administration Server is switched off or unavailable during the time for which the poll is scheduled, the Administration Server can either start the poll immediately after it is switched on, or wait for the next time for which the poll scheduled.
If this option is enabled, the Administration Server starts polling immediately after it is switched on.
If this option is disabled, the Administration Server waits for the next time for which the polling is scheduled.
By default, this option is enabled.
If you want to perform the poll immediately, click Poll now. This button is only available if you selected Enable IP range polling.
On the virtual Administration Server, you can view and edit the settings for IP range polling in the distribution point properties window, in the Device discovery section. Client devices discovered during the poll of IP ranges are displayed in the Domains folder of the virtual Administration Server.
