Remote Monitoring
Command Usage
• If an alarm is already defined for an index, the entry must be deleted before any changes can
be made.
Parameters
These parameters are displayed:
• Index – Index to this entry. (Range: 1-65535)
• Variable – The object identifier of the MIB variable to be sampled. Only variables of the type
etherStatsEntry.n.n may be sampled.
Note that etherStatsEntry.n uniquely defines the MIB variable, and etherStatsEntry.n.n defines
the MIB variable, plus the etherStatsIndex. For example, 1.3.6.1.2.1.16.1.1.1.6.1 denotes
etherStatsBroadcastPkts, plus the etherStatsIndex of 1.
• Interval – The polling interval. (Range: 1-31622400 seconds)
• Sample Type – Tests for absolute or relative changes in the specified variable.
• Absolute – The variable is compared directly to the thresholds at the end of the sampling
period.
• Delta – The last sample is subtracted from the current value and the difference is then
compared to the thresholds.
• Rising Threshold – If the current value is greater than or equal to the rising threshold, and the
last sample value was less than this threshold, then an alarm will be generated. After a rising
event has been generated, another such event will not be generated until the sampled value
has fallen below the rising threshold, reaches the falling threshold, and again moves back up
to the rising threshold. (Range: 0-2147483647)
• Rising Event Index – The index of the event to use if an alarm is triggered by monitored
variables reaching or crossing above the rising threshold. If there is no corresponding entry in
the event control table, then no event will be generated. (Range: 0-65535)
• Falling Threshold – If the current value is less than or equal to the falling threshold, and the
last sample value was greater than this threshold, then an alarm will be generated. After a
falling event has been generated, another such event will not be generated until the sampled
value has risen above the falling threshold, reaches the rising threshold, and again moves
back down to the failing threshold. (Range: 0-2147483647)
• Falling Event Index – The index of the event to use if an alarm is triggered by monitored
variables reaching or crossing below the falling threshold. If there is no corresponding entry in
the event control table, then no event will be generated. (Range: 0-65535)
• Owner – Name of the person who created this entry. (Range: 1-127 characters)
Interface
To configure an RMON alarm:
1. Click Administration, RMON.
2. Select Configure Global from the Step list.
3. Select Add from the Action list.
4. Click Alarm.
5. Enter an index number, the MIB object to be polled (etherStatsEntry.n.n), the polling interval,
the sample type, the thresholds, and the event to trigger.
