30 Sec • Indicates that the RMON statistics are refreshed
every 30 seconds.
60 Sec • Indicates that the RMON statistics are refreshed
every 60 seconds.
Drop Events Displays the number of dropped events
that have occurred on the interface since the device was
last refreshed.
Received Bytes (Octets) Displays the number of octets
received on the interface since the device was last
refreshed. This number includes bad packets and FCS
octets, but excludes framing bits.
Received Packets Displays the number of packets
received on the interface, including bad packets,
Multicast and broadcast packets, since the device was last
refreshed.
Broadcast Packets Received Displays the number of
good broadcast packets received on the interface since
the device was last refreshed. This number does not
include Multicast packets.
Multicast Packets Received Displays the number of
good Multicast packets received on the interface since the
device was last refreshed.
CRC & Align Errors Displays the number of CRC and
Align errors that have occurred on the interface since the
device was last refreshed.
Undersize Packets Displays the number of undersized
packets (less than 64 octets) received on the interface
since the device was last refreshed.
Oversize Packets Displays the number of oversized
packets (over 1518 octets) received on the interface since
the device was last refreshed.
Fragments Displays the number of fragments (packets
with less than 64 octets, excluding framing bits, but
including FCS octets) received on the interface since the
device was last refreshed.
Jabbers Displays the total number of received packets
that were longer than 1518 octets. This number excludes
frame bits, but includes FCS octets that had either a bad
Frame Check Sequence (FCS) with an integral number of
octets (FCS Error) or a bad FCS with a non-integral octet
(Alignment Error) number. The field range to detect
jabbers is between 20 ms and 150 ms.
Collisions Displays the number of collisions received on
the interface since the device was last refreshed.
Frames of xx Bytes Number of xx-byte frames received
on the interface since the device was last refreshed.
Clear Counters button This option will reset all of the
statistic counts.

statistics.
Statistics > RMON History
The RMON History screen contains information about
samples of data taken from ports. For example, the samples
may include interface definitions or polling periods.
Statistics > RMON History
The RMON History screen is divided into RMON History
and Log Table.
Source Interface Displays the interface from which the
history samples were taken. The possible field values are:
Port • Specifies the port from which the RMON
information was taken.
LAG • Specifies the port from which the RMON
information was taken.
Sampling Interval Indicates (in seconds) the time
that samplings are taken from the ports. The field range
is 1-3600. The default is 1800 seconds (equal to 30
minutes).
Max No. of Samples to Keep Indicates the number of
samples to save.
Owner Displays the RMON station or user that requested
the RMON information. The field range is 0-20 characters.
The Add to List button adds the configured RMON
sampling to the Log Table at the bottom of the screen.
Log Table
Sampling Requested Displays the number of samples to
be saved. The field range is 1-65535. The default value is
50.
