Statistic

Description

 

 

RMON Statistics

 

• Drop Events

The total number of events in which packets were dropped

 

due to lack of resources.

• 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.

• Received Bytes

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

 

statistic can be used as a reasonable indication of Ethernet

 

utilization.

• Collisions

The best estimate of the total number of collisions on this

 

Ethernet segment.

• 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 Errors

The number of CRC/alignment errors (FCS or alignment

 

errors).

• 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.

• 64 Bytes 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

128-255 Byte Frames

and transmitted where the number of octets fall within the

256-511 Byte Frames

specified range (excluding framing bits but including FCS

512-1023 Byte Frames

octets).

1024-1518 Byte Frames

 

1519-1536 Byte Frames
