What MIB-2 OID does Smarts use for creating the layering relationship for network adapters?
What MIB-2 OID does Smarts use to populate the value of layeredover Attribute for an Interface?

Smarts uses the ifStackOID { ".1.3.6.1.2.1.31.1.2.1.3" } for creating the layering relationship for network adapters:

ifStackOID { ".1.3.6.1.2.1.31.1.2.1.3" }

Indexes: 1: ifStackHigherLayer 
             2: ifStackLowerLayer 

Information is provided on a particular relationship between two sub-layers, specifying that one sub-layer runs on 'top' of the other sub-layer. Each sub-layer corresponds to a conceptual row in the ifTable. The ic-ifmib-stack.asl file is responsible for creating the layering as in the following example:

62: ifStackStatus.163.0 (INTEGER) active(1)
63: ifStackStatus.164.163 (INTEGER) active(1)
66: ifStackStatus.167.0 (INTEGER) active(1)
67: ifStackStatus.168.167 (INTEGER) active(1)
68: ifStackStatus.169.0 (INTEGER) active(1)
69: ifStackStatus.172.162 (INTEGER) active(1)
70: ifStackStatus.173.164 (INTEGER) active(1)
71: ifStackStatus.173.168 (INTEGER) active(1)
