Item	Description
LearnedEntryDiscard	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 will effect 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	Time-out period in seconds for aging out dynamically learned
	forwarding information.
	Note: The 802.1D-1990 specification recommends a default of
	300 seconds.

Forwarding tab

The Forwarding tab displays the current state of the port, as defined by application of the Spanning Tree Protocol. This state controls what action a port takes on reception of a frame. If the bridge detects a port that is malfunctioning, it places the port into the “broken” state. For ports that are disabled, the value is “disabled.”
