Internal MAC Receive

Errors

A count of frames for which reception on a particular interface fails

due to an internal MAC sublayer receive error.

Internal MAC Transmit

Errors

A count of frames for which transmission on a particular interface

fails due to an internal MAC sublayer transmit error.

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.

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 Octets

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

statistic can be used as a reasonable indication of Ethernet

utilization.

Received Packets

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

received.

Broadcast Packets

The total number of good packets received that were directed to

the broadcast address. Note that this does not include multicast

packets.

Multicast Packets

The total number of good packets received that were directed to

this multicast address.

Undersize Packets

The total number of packets received that were less than 64

octets long (excluding framing bits, but including FCS octets) and

were otherwise well formed.

Oversize Packets

The total number of packets received that were longer than 1518

octets (excluding framing bits, but including FCS octets) and were

otherwise well formed.

64 Bytes Packets

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

transmitted that were 64 octets in length (excluding framing bits

but including FCS octets).

65-127 Byte Packets
128-255 Byte Packets
256-511 Byte Packets
512-1023 Byte Packets
1024-1518 Byte Packets
1519-1536 Byte Packets

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

transmitted where the number of octets fall within the specified

range (excluding framing bits but including FCS octets).

Utilization Statistics

Input Octets per second

Number of octets entering this interface per second.

Input Packets per second Number of packets entering this interface per second.

Input Utilization

The input utilization rate for this interface.

Output Octets per second Number of octets leaving this interface per second.

Output Packets per

second

Number of packets leaving this interface per second.

Output Utilization

The output utilization rate for this interface.
