Introduction

Back to Top

The UISP Remote Discovery feature is a system designed to find devices in your network and easily adapt them to the UISP controller. There are two methods used to discover devices:

  • Scan from the UISP Controller Search for devices in the network(s) connected to the UISP controller.
  • Scan from Devices Search for devices from other currently connected/adopted devices.

The second option allows UISP to discover devices inside private network ranges or behind NAT. It is even possible to automatically upgrade the firmware of a device if it does not meet the minimum requirements. The Scan from Devices option is especially useful for UISP Cloud users as it allows you to automatically discover and connect to local LAN devices from the Cloud.

Firmware and Device Requirements 

Back to Top

NOTE: To perform Remote Discovery, UISP is primarily using an EdgeRouter configured as a UISP Gateway router. But in case there is no such device in the local network, any airMAX AC device with the necessary firmware version can also be used instead. 

The Device Discovery feature is compatible with the latest firmware releases of EdgeMAX and airMAX devices. The minimum required firmware versions are:

  • EdgeRouter v2.0.8+
  • airMAX AC v8.0.7+
  • EdgeSwitch v1.9.0+

The Device Discovery Process

Back to Top

Remote discovery is running automatically in the background searching for all available devices. When first signing up and creating a UISP Cloud instance, for example, you are asked to add a device. If you add an EdgeRouter (with firmware v2.0.8+), UISP can then use the EdgeRouter to discover other devices in the local network (LAN). 

The UISP Remote Discovery feature can be configured from the settings.png  Settings > Devices > Discovery Settings section. The default settings are set automatically, but you can customize the options:

  • Allow unsecured channels By default, the Discovery manager will only send device credentials over secured channels HTTPS/SSH. This option allows discovery to use unsecured channels (e.g. HTTP), but only for private IP address ranges.
  • Scan from UISPSearch for devices in the network(s) connected to the UISP controller.
  • Scan from Devices Search for devices from other currently connected/adopted devices.
  • SNMP community The SNMP community string (set to public by default).
  • Hide third party devices Hide non-Ubiquiti devices from the scan results. 
  • Blacklist IP addresses and subnets that should be ignored by discovery.

The UISP Remote Discovery feature is running automatically in the background searching for all available devices within the IP ranges defined in the  settings.png  Settings > Network > Addresses > Monitored IP subnets section. Initially, it checks if there is a gateway available in each range and if such gateway is found the range is scanned again with higher priority. 

ATTENTION: Remote discovery is only performed for IP ranges defined in the  settings.png  Settings > Network > Addresses > Monitored IP subnets section.

When any IP change is detected by UISP, for example when a new device is connected or when the Monitored IP subnets are changed, the scan is initiated again. This re-scan is also performed periodically in set intervals, but it can also be manually run from the  devices.png  Devices > Discovered section. Here you can also add a specific device by entering its IP address, credentials, and HTTPS port. The device can be added if it is reachable from the UISP server itself or any other device in the local network. 

NOTE: When adding a specific device, it is important to make sure the IP address is correct since device credentials will be transferred.
