Unable to find ports for User Device Tracker

No ports were found in a network discovery that was expected to return devices with active ports.


All versions of SolarWinds UDT.


Typically, a network discovery fails to find ports to import for one or more of the following reasons:

  • You have provided incorrect SNMP credentials for the devices you expected to discover.
  • You did not check the option to "Ignore nodes that only respond to ICMP (ping)" on the Discovery Settings view of Network Discovery, and the devices discovered are ICMP-only with no ports.
  • The nodes discovered do not currently have any actively operational ports.


Confirm the following, and then run discovery again:

  • Your discovery criteria do not exclude the devices on which you expect to find ports.
  • All ports you expect to see on discovered nodes are fully operational.
