Hope you are doing Great!!!
Go into the install directory (example: \Program Files (x86)\SolarWinds\Orion and run the pollerchecker.exe. When running pollchecker, select the devices that are not showing up correctly, select Topology and check the pollers. This will show you if those devices support the MIBs that SolarWinds is using for topology polling.
From the ICX MIB Guide we support the MIB:
If you poll this MIB 1.0.8802.1.1.2.22.214.171.124.4 from any other MIB Browser des it work, if not please provide the out of the poll results.
Hope this helps.
