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 in kbits 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 in kbits per
second
Number of octets leaving this interface in kbits/second.
Output Packets per
second
Number of packets leaving this interface per second.
Output Utilization The output utilization rate for this interface.
