Table 3-11 Port Statistics

Parameter

Description

 

 

Interface Statistics

 

 

 

Received Octets

The total number of octets received on the interface, including framing

 

characters.

Received Unicast Packets

The number of subnetwork-unicast packets delivered to a higher-layer

 

protocol.

Received Multicast Packets

The number of packets, delivered by this sub-layer to a higher (sub-)layer,

 

which were addressed to a multicast address at this sub-layer.

Received Broadcast Packets

The number of packets, delivered by this sub-layer to a higher (sub-)layer,

 

which were addressed to a broadcast address at this sub-layer.

Received Discarded Packets

The number of inbound packets which were chosen to be discarded even

 

though no errors had been detected to prevent their being deliverable to a

 

higher-layer protocol. One possible reason for discarding such a packet

 

could be to free up buffer space.

Received Unknown Packets

The number of packets received via the interface which were discarded

 

because of an unknown or unsupported protocol.

Received Errors

The number of inbound packets that contained errors preventing them

 

from being deliverable to a higher-layer protocol.

Transmit Octets

The total number of octets transmitted out of the interface, including

 

framing characters.

Transmit Unicast Packets

The total number of packets that higher-level protocols requested be

 

transmitted to a subnetwork-unicast address, including those that were

 

discarded or not sent.

Transmit Multicast Packets

The total number of packets that higher-level protocols requested be

 

transmitted, and which were addressed to a multicast address at this

 

sub-layer, including those that were discarded or not sent.

Transmit Broadcast Packets

The total number of packets that higher-level protocols requested be

 

transmitted, and which were addressed to a broadcast address at this

 

sub-layer, including those that were discarded or not sent.

Transmit Discarded Packets

The number of outbound packets which 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 could be to free up

 

buffer space.

Transmit Errors

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

 

errors.

Etherlike Statistics

 

 

 

Alignment Errors

The number of alignment errors (missynchronized data packets).

 

 

Late Collisions

The number of times that a collision is detected later than 512 bit-times

 

into the transmission of a packet.

FCS Errors

A count of frames received on a particular interface that are an integral

 

number of octets in length but do not pass the FCS check. This count does

 

not include frames received with frame-too-long or frame-too-short error.
