RMON Statistics

RMON Statistics display key statistics for each port from RMON group 1. (RMON
groups 2, 3 and 9 can only be accessed using SNMP management software.) The
following screen displays overall statistics on traffic passing through each port.
RMON statistics provide access to a broad range of statistics, including a total count
of different frame types passing through each port. Values displayed have been
accumulated since the last system reboot.

Description
The total number of events in which packets were dropped due to lack of
resources.
Total number of bytes of data received on the network. This statistic can be
used as a reasonable indication of Ethernet utilization.
The total number of frames (bad, broadcast and multicast) received.
The total number of good frames received that were directed to the broadcast
address. Note that this does not include multicast packets.
The total number of good frames received that were directed to this multicast
address.
The number of frames received with CRC/alignment errors (FCS or alignment
errors).
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.
The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise well
formed.
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.
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.
The best estimate of the total number of collisions on this Ethernet segment.
