Port Statistic

Description

 

 

 

 

IfOutDiscards

The number of outbound packets that were chosen to be discarded, even

 

 

though no errors had been detected, to prevent their being transmitted.

 

 

One possible reason for discarding such a packet is to free up buffer

 

 

space.

 

 

 

 

IfOutErrors

The number of outbound packets that could not be transmitted because of

 

 

errors

 

IfOutQLen

The length of the output packet queue (in packets)

 

IpInReceives

The total number of input datagrams received from interfaces, including

 

 

those received in error

 

IpInHdrErrors

The number of input datagrams discarded because of errors in their IP

 

 

headers, including bad checksums, version number mismatch, other

 

 

format errors, time-to-live exceeded, and errors discovered in processing

 

 

their IP options

 

 

 

 

IpForwDatagrams

The number of input datagrams for which this entity was not their final IP

 

 

destination. As a result, an attempt was made to find a route to forward

 

 

them to that final destination. In entities that do not act as IP Gateways, this

 

 

counter includes only those packets that were Source-Routed via this

 

 

entity, and the ones for which Source-Route option processing was

 

 

successful.

 

 

 

 

IpInDiscards

The number of input IP datagrams for which no problems were

 

 

encountered to prevent their continued processing, but which were

 

 

discarded (possibly for lack of buffer space). This counter does not include

 

 

any datagrams discarded while awaiting re-assembly.

 

 

 

 

Dot1dBasePortDelayExceeded

The number of frames discarded by this port because of excessive transit

 

Discards

delay through the bridge. It is incremented by both transparent and source

 

 

route bridges.

 

Dot1dBasePortMtuExceeded

The number of frames discarded by this port because of an excessive size.

 

Discards

It is incremented by both transparent and source route bridges.

 

Dot1dBasePortInFrames

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 only if it is for a protocol being processed by

 

 

the local bridging function, including bridge management frames.

 

 

 

 

Dot1dBasePortOutFrames

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 only if the frame is for a protocol being processed

 

 

by the local bridging function, including bridge management frames.

 

 

 

 

Dot1dBasePortInDiscards

Count of valid frames received that were discarded (filtered) by the

 

 

Forwarding Process

 

EtherStatsDropEvents

The total number of events in which packets were dropped by the probe

 

 

because of lack of resources. This number is not necessarily the number of

 

 

packets dropped, but is the number of times this condition has been

 

 

detected.

 

 

 

 

EtherStatsMulticastPkts

The total number of good packets received that were directed to a

 

 

multicast address. This number does not include packets directed to the

 

 

broadcast address.

 

 

 

 

EtherStatsBroadcastPkts

The total number of good packets received that were directed to the

 

 

broadcast address. This number does not include multicast packets.

 

EtherStatsUndersizePkts

The total number of packets received that were less than 64 octets long

 

 

(excluding framing bits, but including FCS octets) and were otherwise

 

 

well-formed
