Bridging statistics
Use the following command to display the bridging statistics of the selected port:
show interface gigabitethernet
<port number>
bridging-counters
Command mode:
All
Bridging statistics for port 1:
dot1PortInFrames: 63242584
dot1PortOutFrames: 63277826
dot1PortInDiscards: 0
dot1TpLearnedEntryDiscards: 0
dot1StpPortForwardTransitions: 0
The following table describes the bridging statistics for a selected port:
Table 46 Bridging statistics for 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 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.
A frame transmitted on the interface corresponding to this port is 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.
dot1TpLearnedEntryDiscards
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 has adverse performance
effects on the sub network).
If this counter has a significant value but is not presently increasing, it
indicates that the problem has been occurring but is not persistent.
dot1StpPortForwardTransitions
The number of times this port has transitioned from the Learning state to
the Forwarding state.
