l2 Port Learned Entry Discards

1.3.6.1.4.1.52.2501.1.2.8.1.7

The total number of L2 Port table 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 L2 port table 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.
