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.

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.
