table
The table containing information on the relationships
between the multiple sub-layers of network interfaces. In
particular, it contains information on which sub-layers run
'on top of' which other sub-layers, where each sub-layer
corresponds to a conceptual row in the ifTable. For
example, when the sub-layer with ifIndex value x runs over
the sub-layer with ifIndex value y, then this table
contains:
ifStackStatus.x.y=active
For each ifIndex value, I, which identifies an active
interface, there are always at least two instantiated rows
in this table associated with I. For one of these rows, I
is the value of ifStackHigherLayer; for the other, I is the
value of ifStackLowerLayer. (If I is not involved in
multiplexing, then these are the only two rows associated
with I.)
For example, two rows exist even for an interface which has
no others stacked on top or below it:
ifStackStatus.0.x=active
ifStackStatus.x.0=active
