While discovering network infrastructure devices, a switch appears in the inventory topology with a question...

In FortiNAC-F, theInventory topologyuses specific icons to represent the status and model of discovered network infrastructure. When a switch or other network device is discovered via SNMP, FortiNAC-F retrieves itsSystem ObjectID (sysObjectID)to identify the specific make and model. This OID is then compared against the internal database of supported device mappings.

Aquestion mark (?)icon appearing on a discovered switch indicates that while the discovery process successfully communicated with the device (meaning SNMP credentials were correct), theSNMP ObjectID is not recognizedor mapped in the current version of FortiNAC-F. This essentially means the device is " unsupported " by the current software out-of-the-box. Because the OID is unknown, FortiNAC-F does not know which CLI or SNMP command set to use for critical functions like L2 polling (host visibility) or VLAN switching (enforcement). To resolve this, an administrator can manually " Set Device Mapping " to a similar existing model or a " Generic SNMP Device " if only basic L3 visibility is required.

" Discovered devices displaying a ' ? ' iconindicate the currently running version does not have a mapping for that device ' sSystem OID(device is not supported). Device mappings are used to manage the device by performing functions such as L2/L3 Polling, Reading, and Switching VLANs.
