received bridge PDUs.

the Designated Bridge for this port’s segment.

4.3 TRANSPARENT GROUP
do1dTp {dot1dBridge 4}
dot1dTpLearnedEntryDiscards {dot1dTp 1}
Counter Read-Only
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 unpleasant
performance effects on the subnetwork). If this counter has a
significant value but is not presently increasing, it indicates that
the problem has been occurring but is not persistent.
