| Description | This value represents either the InterfaceIndex of
the 'ifLayer' where these Generic Label would be 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 Generic 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 this Generic Label is
being used in forwarding data, then the value of this
object MUST be the InterfaceIndex. |
