Virtual Router Passport Srcl Ste Span Mode

This attribute determines how this bridge port will react when presented with a Spanning Tree Explore frame. If disabled, the Spanning Tree Explore frame is discarded regardless of the value of stpPortState. If the value of this attribute is forced, the Spanning Tree Explore frame is forwarded regardless of the value of stpPortState. autoSpan uses the stpPortState value to decide whether or not Spanning Tree Explore frames should be forwarded out this bridge port. If the port is in the forwarding state, the frame is received and transmitted otherwise the frame is discarded.
