            "Determines how this port behaves when presented
            with a Spanning Tree Explorer frame.  The value
            'disabled(2)' indicates that the port will not
            accept or send Spanning Tree Explorer packets; any
            STE packets received will be silently discarded.
            The value 'forced(3)' indicates the port will
            always accept and propagate Spanning Tree Explorer
            frames.  This allows a manually configured
            Spanning Tree for this class of packet to be
            configured.  Note that unlike transparent
            bridging, this is not catastrophic to the network
            if there are loops.  The value 'auto-span(1)' can
            only be returned by a bridge that both implements
            the Spanning Tree Protocol and has use of the
            protocol enabled on this port. The behavior of the
            port for Spanning Tree Explorer frames is
            determined by the state of dot1dStpPortState.  If
            the port is in the 'forwarding' state, the frame
            will be accepted or propagated.  Otherwise, it
            will be silently discarded."
