This object indicates whether auto-learning is enabled on the port. Note that this object may not be set to true(1) for a port whose bit is turned on in s5SbsPortLearnStatus. Likewise, a port's bit in s5SbsPortLearnStatus may not be turned on if the port's value of s5SbsAutoLearningConfigEnabled is true(1). Note that if this object is changed from true(1) to false(2), all auto-learned MAC addresses for the port will be removed.
