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.
