Object

column r/w Enumeration

For a port running spanning tree, this object represents the 
administrative point-to-point status of the LAN segment
attached to this port, using the enumeration values of
IEEE Std 802.1AC.  A value of forceTrue(1) indicates
that this port should always be treated as if it is
connected to a point-to-point link.  A value of
forceFalse(2) indicates that this port should be treated as
having a shared media connection.  A value of auto(3)
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 adminPointToPointMAC.
              
For a VIP, the adminPointToPointMAC parameter controls
the mechanism by which the Default Backbone Destination
parameter for the VIP is determined.  For a backbone
service instance that includes only 2 VIPs, the value
may be set to forceTrue(1) which permits dynamic learning
of the Default Backbone Destination parameter.  For a
backbone service instance that includes more than 2 VIPs,
the value MUST be set to ForceFalse(2) or auto(3).
              
When this object is set to forceTrue(1) for a VIP, the
Default Backbone Destination parameter is modified by
the subsequent M_UNITDATA.indications as specified in
6.10.1 (and described in 26.4.1).  Whenever the parameter
is set to forceFalse(2) or auto(3), the value for the
Default Backbone Destination parameter is set to the
Backbone Service Instance Group Address for the VIP-ISID. 
              
The value of this object MUST be retained across
reinitializations of the management system.
