Port • Displays the RMON statistics for the selected
port.
LAG • Displays the RMON statistics for the selected
LAG.
Counter Name Displays the selected MIB variable.
Sample Type Defines the sampling method for the
selected variable and comparing the value against the
thresholds. The possible field values are:
Absolute • Compares the values directly with the
thresholds at the end of the sampling interval.
Delta • Subtracts the last sampled value from the
current value. The difference in the values is compared
to the threshold.
Rising Threshold Displays the rising counter value that
triggers the rising threshold alarm. The rising threshold
is presented on top of the graph bars. Each monitored
variable is designated a color.
Rising Event Displays the mechanism in which the alarms
are reported. The possible field values are:
LOG • Indicates there is not a saving mechanism for
either the device or in the management system. If the
device is not reset, the entry remains in the Log Table.
TRAP • Indicates that an SNMP trap is generated, and
sent via the Trap mechanism. The Trap can also be
saved using the Trap mechanism.
Both • Indicates that both the Log and Trap mechanism
are used to report alarms.
Falling Threshold Displays the falling counter value that
triggers the falling threshold alarm. The falling threshold
is graphically presented on top of the graph bars. Each
monitored variable is designated a color.
Falling Event Displays the mechanism in which the
alarms are reported. The possible field values are:
LOG • Indicates there is not a saving mechanism for
either the device or in the management system. If the
device is not reset, the entry remains in the Log Table.
TRAP • Indicates that a SNMP trap is generated, and
sent via the Trap mechanism. The Trap can also be
saved using the Trap mechanism.
Both • Indicates that both the Log and Trap mechanism
are used to report alarms.
Startup Alarm Displays the trigger that activates the
alarm generation. Rising is defined by crossing the
threshold from a low-value threshold to a higher-value
threshold.
Interval Defines the alarm interval time in seconds.
Owner Displays the device or user that defined the
alarm.
The Add to List button adds the RMON Alarms Table
entry.
The Alarm Table area contains the following additional
field:
Counter Value Displays the current counter value for the
particular alarm.
Statistics > RMON Events
An RMON Event determines the action to take when an
alarm is triggered. The response to an alarm can include
logging the alarm or sending an SNMP trap message. If
the response corresponding to an alarm has not yet been
defined, use the RMON Event screen to configure the Event
Setting table.

Event Entry Displays the event.
Community Displays the community to which the event
belongs.
Description Displays the user-defined event description.
Type Describes the event type. Possible values are:
None • Indicates that no event occurred.
Log • Indicates that the event is a log entry.
Trap • Indicates that the event is a trap.
Log and Trap • Indicates that the event is both a log
entry and a trap.
Owner Displays the device or user that defined the
event.
