Field

Description

 

 

Packets Received 1519-1522 Octets

The total number of packets (including bad packets) received

 

that were between 1519 and 1522 octets in length inclusive

 

(excluding framing bits but including FCS octets).

 

 

Packets Received > 1522 Octets

The total number of packets received that were longer than

 

1522 octets (excluding framing bits, but including FCS octets)

 

and were otherwise well formed.

Packets Received Successfully

 

 

 

Total

The total number of packets received that were without errors

 

 

Unicast Packets Received

The number of subnetwork-unicast packets delivered to a

 

higher-layer protocol

 

 

Multicast Packets Received

The total number of good packets received that were directed

 

to a multicast address. Note that this number does not include

 

packets directed to the broadcast address.

 

 

Broadcast Packets Received

The total number of good packets received that were directed

 

to the broadcast address. Note that this does not include

 

multicast packets.

Packets Received with MAC Errors

 

 

 

Total

The total number of inbound packets that contained errors

 

preventing them from being deliverable to a higher-layer

 

protocol

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). Note that 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/Undersize Received

The total number of packets received that were less than 64

 

octets in length (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

 

 

Received Packets not forwarded

 

 

 

Total

A count of valid frames received which were discarded (i.e.

 

filtered) by the forwarding process
