Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-create

Description: The ifIndex of an interface over which this SMDS interface is to be layered. A value of zero indicates no layering. An implementation may choose to require that a nonzero value be configured at entry creation.

What is usdSmdsIfLowerIfIndex?

This read-create value identifies the ifIndex of the lower-layer interface that this SMDS interface is layered on top of, with zero meaning no layering. It's required at row creation to tell the system which physical or logical interface carries the SMDS traffic. An admin stacking an SMDS interface over a specific ATM or serial interface would set this to that interface's ifIndex.
