The administrative point-to-point status of the LAN segment
attached to this port, using the enumeration values of the
IEEE 802.1w clause. A value of forceTrue(0) indicates
that this port should always be treated as if it is
connected to a point-to-point link. A value of
forceFalse(1) indicates that this port should be treated as
having a shared media connection. A value of auto(2)
indicates that this port is considered to have a
point-to-point link if it is an Aggregator and all of its
members are aggregatable, or if the MAC entity
is configured for full duplex operation, either through
auto-negotiation or by management means. Manipulating this
object changes the underlying adminPortToPortMAC.
The value of this object MUST be retained across
reinitializations of the management system.
