rmon alarm
This command sets threshold bounds for a monitored variable. Use the no
form to remove an alarm.

no rmon alarm index
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)
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.
threshold – An alarm threshold for the sampled variable.
(Range: 0-2147483647)
event-index – The index of the event to use if an alarm is triggered.
If there is no corresponding entry in the event control table, then no
event will be generated. (Range: 1-65535)
name – Name of the person who created this entry. (Range: 1-127
characters)

Rising threshold is 892800, assigned to event 0
Falling threshold is 446400, assigned to event 0

◆
If an event is already defined for an index, the entry must be deleted
before any changes can be made with this command.
◆
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.
