B. SNMP MIBs and Traps, and RMON Alarm Defaults
9128-A2-GB20-80 September 2002
B-19
Rising Event Operation
If a rising threshold is crossed during the interval shown in a table (e.g., frames
dropped by the network), the event is armed and an alarm is generated at the end
of the interval. Only one alarm per event per interval is generated. The alarm
condition persists until the event has been disarmed (reset).
The event is disarmed when a falling threshold has been crossed and the rising
threshold has not been crossed during an interval, allowing the event to return to
its original disarmed state.
Physical Interface Alarm Defaults
This alarm only applies to the FrameSaver unit’s network interface.
