usrBRBaseLearnedEntryDiscards
Module: Usr-bridge-MIB
OID (symbolic): Usr-bridge-MIB::usrBRBaseLearnedEntryDiscards
OID (numeric): 1.3.6.1.4.1.429.4.14.1.6
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The total number of Forwarding Database entries, which have been or would have been learnt, 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.
What is usrBRBaseLearnedEntryDiscards?
This counts forwarding-database entries that were or would have been learned but were discarded due to insufficient table space; a rising count signals the MAC table is regularly filling up (which hurts forwarding performance), while a static nonzero value with no further growth means the problem occurred in the past but isn't ongoing.
