Cisco Cisco Aironet 340 Ethernet Bridges Guia Do Utilizador

The spanning tree protocol is listening on the backbone port to look for 
other bridges in the infrastructure. 

The spanning tree protocol is listening on the backbone port. It adds any 
addresses it sees into the Association Table before it starts forwarding 
packets in order to avoid flooding packets unnecessarily.

The spanning tree protocol has allowed the backbone port to forward 
data packets to the radio network.

The spanning tree protocol has determined that the backbone port must 
be automatically disabled to prevent a loop in the infrastructure. 

The unit whose address is given in the log, has lost contact with the des-
ignated bridge on its LAN. It will begin to arbitrate with other bridges 
on the LAN to see who will take over.

Somewhere on the infrastructure a new port has been enabled or dis-
abled. Because of these possible changes to the spanning tree, the bridge 
will begin using a short staleout time for backbone nodes in case the 
location of nodes changes.

This log is produced when the BOOTP server gives the Aironet 340 
Series Bridge the name of a configuration file and then the name of a 
firmware file to load.
