Parameter Description
Drop Events The total number of events in which packets were dropped by the probe
due to lack of resources.
Received Bytes Total number of bytes of data received on the network. This statistic can be
used as a reasonable indication of Ethernet utilization.
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 For 1OMbs ports, the counter records CRC/alignment errors (FCS or
alignment errors). For 10OMbs ports, the counter records the sum of CRC/
alignment errors and code errors (frame received with rxerror signal).
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.
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.
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
64 Byte 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 and
transmitted that were between 65 and 127 octets in length inclusive
(excluding framing bits but including FCS octets).
128-255 Byte
Frames The total number of packets (including bad packets) received and
transmitted that were between 128 and 255 octets in length inclusive
(excluding framing bits but including FCS octets).
1024-1518 Byte
Frames The total number of packets (including bad packets) received and
transmitted that were between 1024 and 1518 octets in length inclusive
(excluding framing bits but including FCS octets).
