The administrative port's connection type for this
spanning tree instance. This parameter is used to
optimise the fast Spanning Tree (6.4.3 of P802.1w).
The default value is nopointtopoint(1). The value
pointtopoint(2) forces the port to be treated as if
it is connected through a point-to-point LAN segment
to another switch. Set this parameter to autopointtopoint(3)
makes the point-to-point status to be determined automatically
by the MAC entity. The value edgeport(4) indicates that the
port is considered to be an edge port (18.3.3 of P802.1t).
