How does Spectrum populate the MAC_Address attribute id 0x110df of a device model during model creation

Environment

Any Spectrum version

Resolution

When a new device is modeled in Spectrum, Spectrum takes the ip address used to create the model and checks the ipAddrTable and ipAddressTable tables for that ip address.

If the ip address is in the ipAddrTable, Spectrum reads the value of the ipAdEntIfIndex attribute in the ipAddrTable for that ip address.

If the ip address is in the ipAddressTable , Spectrum reads the value of the ipAddressIfIndex attribute in the ipAddressTable for that ip address.

Then, Spectrum reads the value of the ifPhysAddress attribute in the interfaces table for that specific ifIndex and populates the MAC_Address attribute id 0x110df of the device model with the value read.
