Module: RFC1286-MIB
OID (symbolic): RFC1286-MIB::dot1dSrPortSteInFrames
OID (numeric): 1.3.6.1.2.1.17.3.1.1.12
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of spanning tree explorer frames that have been received by this port from its segment.
What is dot1dSrPortSteInFrames?
This counter tracks the number of Spanning Tree Explorer frames the port has received from its segment. Admins watch it to confirm Spanning Tree Explorer traffic, used for loop-safe broadcast-style delivery, is reaching the bridge on this port. A count that never increments on a port expected to see explorer traffic points to a wiring or segment mismatch.
