Statistics Tab - RMON Alarms
The RMON Alarms screen displays the network alarms you have set. When the network experiences problems or
events, such as rising and falling thresholds, then a network alarm will occur.
Alarm Entry. This identifies a specific alarm.
Counter Name. This is the selected MIB (Management Information Base) variable; for example, this can be the
total number of octets received, the number of unicast packets transmitted, the number of pause frames
received, the number of oversize packets.
Interface. This is the interface for which RMON statistics are displayed, either a port or LAG.
Counter Value. This is the value of the selected MIB variable.
Sample Type. This is the sampling method for the selected variable, Delta, which subtracts the last sampled
value from the current value and then compares the difference to the threshold, or Absolute, which compares
values directly with the thresholds at the end of the sampling interval.
Rising Threshold. This is the rising counter value that triggers the rising threshold alarm.
Rising Event. This is how alarms are reported, by Log, Trap, or Log and Trap.
Falling Threshold. This is the falling counter value that triggers the falling threshold alarm.
Falling Event. This is how alarms are reported, by Log, Trap, or Log and Trap.
