to clear statistics for this port.
Operational Status
Enables or disables the port.
RMON Operational Status
Enables or disables RMON for the port.
The next several tables contain specific information about bridging, interface (input and output), and
Ethernet statistics.
Bridging (“dot1”) Statistics
The following table describes the bridging statistics of the selected port:
Table 61
Bridging statistics of a port
Statistic Description
InFrames
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 only counted by this object if and only if it is for a
protocol being processed by the local bridging function, including bridge management frames.
OutFrames
The number of frames that have been transmitted by this port to its segment. Note that a frame
transmitted on the interface corresponding to this port is only counted by this object if and only
if it is for a protocol being processed by the local bridging function, including bridge
management frames.
InDiscards
Count of valid frames received that were discarded (that is, filtered) by the Forwarding Process.
EntryDiscards
The total number of Forwarding Database entries, which have been or would have been learnt,
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 unpleasant 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.
PortForward
Transitions
The number of times this port has transitioned from the Learning state to the Forwarding state.
Link-State Change The number of times an interface has transitioned from either down to up or from up to down.
Interface (“if”) Statistics - Input
The following table describes the interface input statistics of the selected port:
Table 62
Interface Statistics for a Port - Input
Statistic Description
HC Octets
The total number of octets received on the interface, including framing characters.
HC UCastPkts
The number of packets, delivered by this sub layer to a higher sub layer, which were not
addressed to a multicast or broadcast address at this sub layer.
