Figure 8-121. RMON Alarms
Alarm Entry — Indicates a specific alarm.
Interface — The interface for which RMON statistics are displayed.
Counter Name — The selected MIB variable.
Counter Value — The value of the selected MIB variable.
Sample Type — Specifies the sampling method for the selected variable and comparing the value
against the thresholds. The possible field values are:
Delta — Subtracts the last sampled value from the current value. The difference in the values
is compared to the threshold.
Absolute — Compares the values directly with the thresholds at the end of the sampling
interval.
Rising Threshold — 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 /Falling Event — The mechanism in which the alarms are reported — LOG, TRAP, or a
combination of both. When LOG is selected, there is no saving mechanism either in the Ethernet
Switch Module or in the management system. However, if the Ethernet Switch Module is not
being reset, it remains in the Ethernet Switch Module LOG table. If TRAP is selected, an SNMP
trap is generated and reported via the trap's general mechanism. The TRAP can be saved using the
same mechanism.
