rxr1dTpLearnedEntryDiscards
Module: IBM-RXR-MIB
OID (symbolic): IBM-RXR-MIB::rxr1dTpLearnedEntryDiscards
OID (numeric): 1.3.6.1.4.1.2.6.26.1.4.1
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 rxr1dTpLearnedEntryDiscards?
Counts forwarding-database entries this bridge either discarded or never learned in the first place because the address table ran out of space. A steadily rising count means the bridge's MAC address table is regularly filling up, which hurts forwarding performance across the whole subnetwork; a high but static value means the problem happened in the past but isn't ongoing.
