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.”

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.
