| Description | This value represents either the InterfaceIndex of
the 'ifLayer' where the ATM Labels 'owned' by this
entry were created, or 0 (zero). The value of zero
means that the InterfaceIndex is not known. For example,
if the InterfaceIndex is created subsequent to the
ATM Label's creation, then it would not be known.
However, if the InterfaceIndex is known, then it must
be represented by this value.
If an InterfaceIndex becomes known, then the
network management entity (e.g. SNMP agent) responsible
for this object MUST change the value from 0 (zero) to the
value of the InterfaceIndex. If an ATM Label is
being used in forwarding data, then the value of this
object MUST be the InterfaceIndex. |
