Description: 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.
What is dot1dSrPortSTESpanMode?
This object determines how the port handles Spanning Tree Explorer frames: disabled discards them, forced always accepts and propagates them, and auto-span defers to the bridge's Spanning Tree Protocol state. Admins use forced mode to manually configure an explorer-frame spanning tree when the automatic Spanning Tree Protocol isn't running on that port. Setting it to disabled(2) would stop this port from participating in Spanning Tree Explorer frame propagation.
