Symbol Errors Symbol errors occur when port interface hardware cannot decode the
bits received electrically from the cable connection. A large amount of
symbol errors indicates a possible hardware issue.
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
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).
CRC Align Errors Errors caused by cyclic redundancy check failures. Possible issues
include hardware, cabling, or grounding.
Utilization Statistics
Input Octets in kbits per
second
Number of octets entering this interface in kbits/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.
