Table 43 Bridging Statistics of a Port
Statistics 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 if and 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 that a frame transmitted on the interface corresponding
to this port is only counted by this object if and only if it is for a
protocol being processed by the local bridging function, including
bridge management frames.
dot1PortInDiscards Count 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 learnt, 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 has unpleasant performance effects on the
subnetwork). If this counter has a significant value but is not presently
increasing, it indicates that the problem has been occurring but is not
persistent.
dot1StpPortForward
Transitions
The number of times this port has transitioned from the Learning state
to the Forwarding state.
