Current Number of Samples Displays the current
number of samples taken.
RMON History
Statistics > History Table
The RMON History screen contains interface specific
statistical network samplings. Each table entry represents
all counter values compiled during a single sample.
History Entry No Displays the history table entry
number.
Owner Displays the RMON station or user that requested
the RMON information. The field range is 0-20 characters.
Sample No Indicates the sample number from which the
statistics were taken.
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 since the device was last
refreshed, including bad packets, Multicast and Broadcast
packets.
Broadcast Packets 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 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.
Utilization Displays the percentage of the interface
utilized.
Statistics > RMON Alarms
The RMON Alarm screen contains fields for setting network
alarms. Network alarms occur when a network problem, or
event, is detected. Rising and falling thresholds generate
events.
Statistics > RMON Alarms
Alarm Entry Indicates a specific alarm.
Source Interface Displays the interface for which RMON
statistics are displayed. The possible field values are:
