OUI (Organizationally Unique Identifier)

IP Fabric includes an OUI (Organizationally Unique Identifier) MAC table of network device manufacturer and uses it during the discovery process whenever there is a network device discovered through the ARP table.

OUI table

This table can be found in Settings → Discovery & Snapshots → Global Configuration → OUI.

It contains an OUI (the start of a device’s MAC address), the vendor to whom this OUI belongs and if it is enabled (can be used) during the discovery process.

Custom OUIs can be added with the + Add OUI button.

All OUIs can be enabled or disabled for discovery through the Edit button.


If there are network devices in your infrastructure that were found as hosts and IP Fabric did not try to connect to them during the discovery, please refer to this table and check if OUIs of those devices are enabled for discovery.
