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.”
To view the Forwarding tab:
1 From the Device Manager menu bar, choose Edit > Bridge.

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.
