Port bridging statistics are described in the following table:
 
Port Bridging Statistics (/stats/port/brg) 
Statistic
Description
dot1PortInFrames
The number of frames that have been received by this port from its segment. A frame received on the interface corresponding to this port is only counted by this object only if it is for a protocol being processed by the local bridging function, including bridge management frames.
dot1PortOutFrames
The number of frames that have been transmitted by this port to its segment.
Note: A frame transmitted on the interface corresponding to this port is only counted by this object only if it is for a protocol being processed by the local bridging function, including bridge management frames.
dot1PortInDiscards
Number of valid frames received which were discarded (that is, filtered) by the forwarding process.
dot1TpLearnedEntry Discards
The total number of forwarding database entries which have been or would have been learned, but have been discarded due to a lack of space to store them in the forwarding database. If this counter is increasing, it indicates that the forwarding database is regularly becoming full (a condition which may have negative performance effects on the subnetwork). If this counter has a very large value but is not presently increasing, it indicates that the problem has been occurring but is not persistent.
dot1BasePortDelay ExceededDiscards
The number of frames discarded by this port due to excessive transit delay through the bridge. It is incremented by both transparent and source route bridges.
dot1BasePortMtu ExceededDiscards
The number of frames discarded by this port due to excessive size. It is incremented by both transparent and source route bridges.
dot1StpPortForward Transitions
The number of times this port has transitioned from the learning state to the forwarding state.
