Configuring Front Servers

NetBrain Front Server provides Ping/SNMP/Telnet/SSH/Traceroute proxy services to access your live network and collect live data. Once a device is successfully discovered by a Front Server, it will be automatically allocated to the Front Server or the Front Server Group for future live access.

Example: Existing Front Servers and Front Server Groups are displayed. The Allocated Devices column displays the number of devices using this Front Server or Front Server Group for live access, such as Discovery, Benchmark or Runbook; The Allocated Devices for Preventive Automation displays the number of devices using this Front Server for Preventive Automation.


To reallocate devices to a Front Server or Front Server Group, select either way of the following：

  • Reallocate devices to a Front Server

  1. In the Allocated Devices or Allocated Devices for Preventive Automation column, click the number in the target entry.
  2. In the pop-up dialog, click +Device.
  3. Filter devices by device type, device group or site.
  4. Select the target devices by pressing the Ctrl or Shift key, and then click the  icon.
  5. Click OK.
  • Reallocate devices to a Front Server Group
  1. In the Allocated Devices or Allocated Devices for Preventive Automation column, click the number in the target entry.
