After identity attributes are captured, they can be viewed with show commands on the switch. The identity ID Name assigned to each identity depends on the identity attributes collected. For example, if a MAC address detected by FDB (forwarding database) is not correlated by at least one other software component, the identity is considered an unknown identity, and identity manager creates an identity entry with the name unknown_<MAC-Address>, where MAC-Address is replaced with the actual MAC address.
When an FDB detected MAC address is correlated by another software component, the identity is considered a known identity, and the identity manager names the identity based on the identity attributes.
For example, if a user name is collected, the user name becomes the ID name. If a username is not discovered, identity manager creates a name based on the MAC address.
Note
If FDB triggers the removal of the MAC address for an unknown identity, the identity manager deletes the corresponding unknown identity after a period of time.
