Chapter 4: Bridge MIBPage 4-10Fast Network 10 MIB Reference Guidedot1dSrPortSTESpanMode {dot1dSrPortEntry 7}Integer Read-WriteDetermines how this port behaves when presented with a Spanning Tree Explorerframe. The value disabled(2) indicates that the port will not accept or sendSpanning Tree Explorer packets; any STE packets received will be silentlydiscarded. The value forced(3) indicates the port will always accept andpropagate Spanning Tree Explorer frames. This allows a manually configuredSpanning Tree for this class of packet to be configured. Note that unliketransparent bridging this is not catastrophic to the network if there are loops. Thevalue auto-span(1) can only be returned by a bridge that both implements theSpanning Tree Protocol and has use of the protocol enabled on this port. Thebehavior of the port for Spanning Tree Explorer frames is determined by the stateof dot1dStpPortState. If the port is in the forwarding state, the frame will beaccepted or propagated. Otherwise it will be silently discarded.dot1dSrPortSpecInFrames {dot1dSrPortEntry 8}Counter Read-OnlyThe number of specifically routed frames that have been received from this port’ssegment.dot1dSrPortSpecOutFrames {dot1dSrPortEntry 9}Counter Read-OnlyThe number of specifically routed frames that this port has transmitted on itssegment.dot1dSrPortApeInFrames {dot1dSrPortEntry 10}Counter Read-OnlyThe number of all paths explorer frames that have been received by this port fromits segment.dot1dSrPortApeOutFrames {dot1dSrPortEntry 11}Counter Read-OnlyThe number of all paths explorer frames that have been transmitted by this porton its segment.dot1dSrPortSteInFrames {dot1dSrPortEntry 12}Counter Read-OnlyThe number of spanning tree explorer frames that have been received by this portfrom its segment.
