The following table describes the bridging statistics for a selected port:Table 47 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.

 

 

dot1StpPortForwardTransitionsThe number of times this port has transitioned from the Learning state to the

 

Forwarding state.

Statistics

Description

 

 

dot3StatsAlignmentErrorsA 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.
