Node type: OBJECT-TYPE

What is juniSmdsMajorIfLowerIfIndex?

This identifies the ifIndex of the underlying interface that a given SMDS major interface is layered over, with zero meaning no layering interface is configured. It lets the router know which physical link (for example a T3 or serial port) actually carries the SMDS major interface's traffic. An admin building a new major interface entry supplies this alongside juniSmdsMajorIfRowStatus=createAndGo to bind the SMDS service to that lower-layer port.
