Parameter

Description

Drop Events

The total number of events in which packets were dropped due to

 

lack of resources.

Received Bytes

Total number of bytes of data received on the network. This

 

statistic can be used as a reasonable indication of Ethernet

 

utilization.

Received Frames

The total number of frames (bad, broadcast and multicast)

 

received.

Broadcast Frames

The total number of good frames received that were directed to

 

the broadcast address. Note that this does not include multicast

 

packets.

Multicast Frames

The total number of good frames received that were directed to

 

this multicast address.

CRC/Alignment

For 10Mbs ports, the counter records CRC/alignment errors

Errors

(FCS or alignment errors). For 100Mbs ports, the counter records

 

the sum of CRC/alignment errors and code errors (frame

 

received with rxerror signal).

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.

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.

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.

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.

Collisions

The best estimate of the total number of collisions on this

 

Ethernet segment.

64 Byte Frames

The total number of frames (including bad packets) received and

 

transmitted that were 64 octets in length (excluding framing bits

 

but including FCS octets).

65-127 Byte Frames

The total number of frames (including bad packets) received and

 

transmitted that were between 65 and 127 octets in length

 

inclusive (excluding framing bits but including FCS octets).

128-255 Byte Frames

The total number of packets (including bad packets) received and

 

transmitted that were between 128 and 255 octets in length

 

inclusive (excluding framing bits but including FCS octets).

1024-1518 Byte

The total number of packets (including bad packets) received and

Frames

transmitted that were between 1024 and 1518 octets in length

 

inclusive (excluding framing bits but including FCS octets).
