Parameter

Description

 

 

Undersize Frames

The total number of frames received that were less

 

than 64 octets long (excluding framing bits, but

 

including FCS octets) and were otherwise well

 

formed.

 

 

Fragments

The total number of frames received that were less

 

than 64 octets in length (excluding framing bits, but

 

including FCS octets) and had either an FCS or

 

alignment error.

 

 

Collisions

The best estimate of the total number of collisions on

 

this Ethernet segment.

 

 

Received Bytes

Total number of bytes of data received on the

 

network. This statistic can be used as a reasonable

 

indication of Ethernet utilization.

 

 

Broadcast Frames

The total number of good frames received that were

 

directed to the broadcast address. Note that this does

 

not include multicast packets.

 

 

CRC/Alignment Errors

The number of CRC/alignment errors (FCS or

 

alignment errors).

 

 

Oversize Frames

The total number of frames received that were longer

 

than 1518 octets (excluding framing bits, but

 

including FCS octets) and were otherwise well

 

formed.

 

 

Jabbers

The total number of frames received that were longer

 

than 1518 octets (excluding framing bits, but

 

including FCS octets), and had either an FCS or

 

alignment error.
