Description

 

 

Jabbers Received

The total number of packets received that were longer than 1518 octets

 

 

 

(excluding framing bits, but including FCS octets), and had either a bad Frame

 

 

 

Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad

 

 

 

FCS with a non-integral number of octets (Alignment Error). This definition of

 

 

 

jabber is different than the definition in IEEE 802.3 section 8.2.1.5 (10BASE5)

 

 

 

and section 10.3.1.4 (10BASE2). These documents define jabber as the

 

 

 

condition where any packet exceeds 20 ms. The allowed range to detect

 

 

 

jabber is between 20 ms and 150 ms.

 

 

 

 

 

 

Fragments Received

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

 

 

 

with ERROR CRC (excluding framing bits but including FCS octets).

 

 

 

 

 

 

Undersize Received

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

 

 

 

with GOOD CRC (excluding framing bits but including FCS octets).

 

 

 

 

 

 

Alignment Errors

The total number of packets received that had a length (excluding framing bits,

 

 

 

but including FCS octets) of between 64 and 1518 octets, inclusive, but had a

 

 

 

bad Frame Check Sequence (FCS) with a non-integral number of octets.

 

 

 

 

 

 

Rx FCS Errors

The total number of packets received that had a length (excluding framing bits,

 

 

 

but including FCS octets) of between 64 and 1518 octets, inclusive, but had a

 

 

 

bad Frame Check Sequence (FCS) with an integral number of octets

 

 

 

 

 

 

Overruns

The total number of frames discarded as this port was overloaded with

 

 

 

incoming packets, and could not keep up with the inflow.

 

 

 

 

 

 

Total Received Packets Not

A count of valid frames received which were discarded (i.e., filtered) by the

 

 

Forwarded

forwarding process.

 

 

 

 

 

 

Local Traffic Frames

The total number of frames dropped in the forwarding process because the

 

 

 

destination address was located off of this port.

 

 

 

 

 

 

802.3x Pause Frames

A count of MAC Control frames received on this interface with an opcode

 

 

Received

indicating the PAUSE operation. This counter does not increment when the

 

 

 

interface is operating in half-duplex mode.

 

 

 

 

 

 

Unacceptable Frame Type

The number of frames discarded from this port due to being an unacceptable

 

 

 

frame type.

 

 

 

 

 

 

Total Packets Transmitted

The total number of octets of data (including those in bad packets) transmitted

 

 

(Octets)

on the network (excluding framing bits but including FCS octets). This object

 

 

 

can be used as a reasonable estimate of Ethernet utilization. If greater

 

 

 

precision is desired, the etherStatsPkts and etherStatsOctets objects should

 

 

 

be sampled before and after a common interval.

 

 

 

 

 

 

Packets Transmitted 64

The total number of packets (including bad packets) transmitted that were 64

 

 

Octets

octets in length (excluding framing bits but including FCS octets).

 

 

 

 

 

 

Packets Transmitted

The total number of packets (including bad packets) transmitted that were

 

 

65-127 Octets

between 65 and 127 octets in length inclusive (excluding framing bits but

 

 

 

including FCS octets).

 

 

 

 

 

 

Packets Transmitted

The total number of packets (including bad packets) transmitted that were

 

 

128-255 Octets

between 128 and 255 octets in length inclusive (excluding framing bits but

 

 

 

including FCS octets).
