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

STP: Learning Addresses
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.

STP: Forwarding Data
The spanning tree protocol has allowed the backbone port to forward

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

STP Port “node address” receives hello timeout
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.

STP: Topology Changed
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.

TFTP is loading “file name” from “ip address”
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.
