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.
