dot1dTpLearnedEntryDiscards
Module: CHIPDOT1D-MIB
OID (symbolic): CHIPDOT1D-MIB::dot1dTpLearnedEntryDiscards
OID (numeric): 1.3.6.1.4.1.49.2.4.14.4.1
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 dot1dTpLearnedEntryDiscards?
Read-only counter of forwarding database entries that were dropped (or would have been learned but couldn't be) due to insufficient table space; a rising value signals the bridge's forwarding table is frequently full.
