Fragments
The total number of packets received during this sampling interval that were less than 64 octets in
length (excluding framing bits but including FCS octets) had either a bad Frame Check Sequence
(FCS) with an integral number of octets (FCS Error), or a bad FCS with a non-integral number of
octets (AlignmentError). It is normal for
Jabbers
The number of packets received during this sampling interval that were longer than 1518 octets
(excluding framing bits but including FCS octets), and had either a bad Frame Check Sequence
(FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error).
Dropped
The total number of events in which packets were dropped by the probe due to lack of resources
during this sampling interval. This number is not necessarily the number of packets dropped, it is
just the number of times this condition has been detected.
Collisions
The best estimate of the total number of collisions on this Ethernet segment during this sampling
interval.
5.19.5 rmon alarm
The rmon alarm global configuration command configures alarm conditions. To remove an alarm, use the no form of this
command.
Syntax
rmon alarm index variable interval rthreshold fthreshold revent fevent [type type] [startup direction] [owner name]
no rmon alarm index
index — The alarm index. (Range: 1 - 65535)
variable — The object identifier of the particular variable to be sampled.
interval — The interval in seconds over which the data is sampled and compared with the rising and falling
thresholds. (Range: 1 - 4294967295)
rthreshold — Rising Threshold. (Range: 1 - 4294967295)
fthreshold — Falling Threshold. (Range: 1 - 4294967295)
revent — The Event index used when a rising threshold is crossed .(Range: 0 - 65535)
fevent — The Event index used when a falling threshold is crossed. (Range: 0 - 65535)
type type — The sampling method for the selected variable and calculating the value to be compared against the
thresholds. If the method is absolute, the value of the selected variable is compared directly with the thresholds at the
end of the sampling interval. If the method is delta, the selected variable value at the last sample is subtracted from the
current value, and the difference compared with the thresholds.
