Bridging statistics
Use the following command to display the bridging statistics of the selected port:
show interface gigabitethernet <port number>
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 32 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. |
dot1StpPortForwardTransition | The number of times this port has transitioned from the Learning state to |
s | the Forwarding state. |
