Bridging statistics
Use the following command to display the bridging statistics of the selected port:
show interface port <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.
Ethernet statistics
Use the following command to display the ethernet statistics of the selected port:
show interface port <port number> ethernet-counters

Ethernet statistics for port 1:
dot3StatsAlignmentErrors: 0
dot3StatsFCSErrors: 0
dot3StatsSingleCollisionFrames: 0
dot3StatsMultipleCollisionFrames: 0
dot3StatsLateCollisions: 0
dot3StatsExcessiveCollisions: 0
dot3StatsInternalMacTransmitErrors: NA
dot3StatsFrameTooLongs: 0
