Rmon Alarm - Allied Telesis AT-8000S Cli Reference Manual

Allied Telesyn AT-8000S Switch
CLI Reference Guide
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.

rmon alarm

The rmon alarm Global Configuration mode command configures alarm conditions. To remove an alarm, use the
no form of this command.

Parameters
•
index — Specifies the alarm index. (Range: 1-65535)
•
variable — Specifies the object identifier of the variable to be sampled.
•
interval — Specifies the interval in seconds during which the data is sampled and compared with rising and
falling thresholds. (Range: 1-4294967295)
•
rthreshold — Specifies the rising threshold. (Range: 0-4294967295)
•
fthreshold — Specifies the falling threshold. (Range: 0-4294967295)
•
revent — Specifies the event index used when a rising threshold is crossed.
(Range: 1-65535)
•
fevent — Specifies the event index used when a falling threshold is crossed.
(Range: 1-65535)
•
type — Specifies the method used for sampling the selected variable and calculating the value to be
compared against the thresholds. Possible values are absolute and delta.
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 of the last sample is
subtracted from the current value, and the difference is compared with the thresholds.
•
direction — Specifies the alarm that may be sent when this entry is first set to valid. Possible values are
rising, rising-falling and falling.
If the first sample (after this entry becomes valid) is greater than or equal to rthreshold and direction is equal
to rising or rising-falling, a single rising alarm is generated. If the first sample (after this entry becomes
valid) is less than or equal to fthreshold and direction is equal to falling or rising-falling, a single falling alarm
is generated.
•
name — Specifies the name of the person who configured this alarm. If unspecified, the name is an empty
string.
Default Configuration
The type is absolute.
The startup direction is rising-falling.
