Statistics | Description |
|
|
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. |

Ethernet statistics
Use the following command to display the ethernet statistics of the selected port:
show interface port <port number> ethernet-counters
Command mode: All
Ethernet statistics for port 1:
dot3StatsAlignmentErrors:0
dot3StatsFCSErrors:0
dot3StatsSingleCollisionFrames:0
dot3StatsMultipleCollisionFrames:0
dot3StatsLateCollisions:0
dot3StatsExcessiveCollisions:0
dot3StatsInternalMacTransmitErrors: NA

The following table describes the Ethernet statistics for a selected port:
Table 48 Ethernet statistics for port
Statistics | Description |
|
|
dot3StatsAlignmentErrors | A count of frames received on a particular interface that are not an |
| integral number of octets in length and do not pass the Frame |
| Check Sequence (FCS) check. |
| The count represented by an instance of this object is incremented |
| when the alignmentError status is returned by the MAC service |
| to the Logical Link Control (LLC) (or other MAC user). |
| Received frames for which multiple error conditions obtained are, |
| according to the conventions of IEEE 802.3 Layer Management, |
| counted exclusively according to the error status presented to the |
| LLC. |
