Description
The value of an Ethernet statistical variable (i.e., a member of the Ether-
net statistics group as defined by RFC 1757) has exceeded its rising
threshold. The variable’s rising threshold and whether it will generate an
SNMP
trap for this condition are configured by a network management
station running
RMON
.

Descrip-
tions
An RMON alarm entry crossed its rising threshold (index 25 var 2 type 1
value 201 rising threshold 200)
Alarm Index
. An index value for this entry in the
alarm table. Each entry defines a diagnostic sample
at a particular interval for an object on the device.
Variable . The MIB object identifier
for the variable being sampled.
Sampling Method
. The method of sampling
the selected variable and calculating the
value for comparison with the thresholds.
Possible values are integers 1 and 2:
1 Absolute Value. The value of the
selected variable will be compared
directly with the thresholds at the end
of the sampling interval.
2 Delta Value. The value of the selected
variable at the last sample will be sub-
tracted from the current value, and the
difference compared with the thresh-
olds.
Value
. The value of the statistic
during the last sampling period.
For example, if the sample meth-
od is Delta Value, this value will
be the difference between the
samples at the beginning and end
of the period. If the sample meth-
od is Absolute Value, this value
will be the sampled value at the
end of the period. This is the
value that is compared with the
rising threshold.
Rising Threshold
. A threshold for the sampled statistic. This
trap is generated when the current sampled value is
greater than or equal to this threshold, and the value at
the last sampling interval was less than this threshold.
After a rising event is generated, another such event will
not be generated until the sampled value falls below this
threshold and reaches the Falling Threshold value.
