12 - 4 Ethernet or Token Ring Bridge

SNMP: “command text”

A SNMP management node sent the unit a “set” variable request which

was successfully executed. The “command text” is a similar menu com-

mand that has the same effect as the SNMP request.

SNMP access failure from “community name” “IP address” (node

address)

A SNMP management node attempted to access the SNMP agent with an

invalid community name or a name that it was not allowed to use.

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

data packets to the radio network.

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.
