Bridging statistics

Command: /stats/port <port number>/brg

Bridging statistics for port 1:

dot1PortInFrames:63242584

dot1PortOutFrames:63277826

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

Table 36 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.
