For a port which (potentially) has the same value
of dot1dBasePortIfIndex as another port on the
same bridge, this object contains the name of an
object instance unique to this port. For example,
in the case where multiple ports correspond
one-to-one with multiple X.25 virtual circuits, this
value might identify an (e.g., the first) object
instance associated with the X.25 virtual circuit
corresponding to this port.
For a port which has a unique value of
dot1dBasePortIfIndex, this object can have the
value { 0 0 }. |
