IF-INVERTED-STACK-MIB Table View

A table containing information on the relationships between
          
the multiple sub-layers of network interfaces.  In
particular, it contains information on which sub-layers run
'underneath' 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
underneath the sub-layer with ifIndex value y, then this
table contains:
          
  ifInvStackStatus.x.y=active
          
For each ifIndex value, z, which identifies an active
interface, there are always at least two instantiated rows
in this table associated with z.  For one of these rows, z
is the value of ifStackHigherLayer; for the other, z is the
value of ifStackLowerLayer.  (If z is not involved in
multiplexing, then these are the only two rows associated
with z.)
          
For example, two rows exist even for an interface which has
no others stacked on top or below it:
          
  ifInvStackStatus.z.0=active
  ifInvStackStatus.0.z=active
          
This table contains exactly the same number of rows as the
ifStackTable, but the rows appear in a different order.
