A table containing a list of the bridge ports for
which a particular Spanning Tree instance has been
detected to have BPDU skewing occurred since the
object value of stpxBpduSkewingDetectionEnable was
last changed to true(1).
The agent creates a new entry in this table whenever
a port in a particular Spanning Tree instance is
detected to be BPDU skewed since the object value of
stpxBpduSkewingDetectionEnable object is changed to
true(1). The agent deletes all the entries in this
table when the object value of
stpxBpduSkewingDetectionEnable is changed to false(2)
or the object value of stpxSpanningTreeType is
changed.
