Description
The total number of Forwarding Database entries, which have been or
would have been learned, but have been discarded due to a lack of
space to store them in the Forwarding Database.
If this counter is increasing, it indicates that the Forwarding Database is
regularly becoming full (a condition which has adverse performance
effects on the sub network).
If this counter has a significant value but is not presently increasing, it
indicates that the problem has been occurring but is not persistent.
The number of times this port has transitioned from the Learning state to
the Forwarding state.

Description
A count of frames received on a particular interface that are not an
integral number of octets in length and do not pass the Frame
Check Sequence (FCS) check.
The count represented by an instance of this object is incremented
when the alignmentError status is returned by the MAC service
to the Logical Link Control (LLC) (or other MAC user).
Received frames for which multiple error conditions obtained are,
according to the conventions of IEEE 802.3 Layer Management,
counted exclusively according to the error status presented to the
LLC.
