In most cases the model of SNMP-enabled network devices is determined through the lookup of the asset's OID. You can change it by
- opening the asset summary page and copying the OID
- under Configuration\Asset mapping, section Device Snmp OID lookup, entering the OID into the search field
- changing the model description
If the device OID is not listed here, you could add it to the list.
If the asset page has no OID, you need to edit the asset and manually change the model. Be sure to lock the model field, so Lansweeper won't overwrite your changes during subsequent scans.
