Table 1. Variable definitions
Variable | Value
--- | ---
LearnedEntryDiscards | Number of Forwarding Database entries learned that have been discarded due to a lack of space in the Forwarding Database. If this counter is increasing, it indicates that the Forwarding Database is becoming full regularly. This condition affects the performance of the subnetwork. If the counter has a significant value and is not presently increasing, it indicates that the problem has been occurring but is not persistent.
AgingTime | Timeout period in seconds for aging out dynamically learned forwarding information. Note The 802.1D-1990 specification recommends a default of 300 seconds.
