Variable Set the alarm variable to be monitored. The switch will monitor the specified
variable in sample intervals and act in the set way when the alarm is triggered.
The default variable is RecBytes.
RecBytes: Total received bytes.
RecPackets: Total received packets.
BPackets: Total broadcast packets.
MPackets: Total multicast packets.
CRC&Align ERR: Packets that range from 64 to 1518 bytes and contain FCS
Error or Alignment Error.
Undersize: Packets that are smaller than 64 bytes.
Oversize: Packets that are larger than 1518 bytes.
Jabbers: Packets that are sent when port collisions occur.
Collisions: Collision times in the network segment.
64, 65-127, 128-255, 256-511, 512-1023, 1024-10240: Total packets of the
specified size.
Statistics Associate the alarm entry with a statistics entry. Then the switch monitors the
specified variable of the statistics entry.
2) Set the sample type, the rising and falling threshold, the corresponding event action,
and the alarm type of the entry.
Sample Type Set the sampling method of the specified variable; the default is absolute.
Absolute: Compare the sampling value against the preset threshold.
Delta: The switch obtains the difference between the sampling values of the
current interval and the previous interval, and then compares the difference
against the preset threshold.
Rising Threshold Set the rising threshold of the variable. When the sampled value exceeds the
threshold, the system will trigger the corresponding Rising Event. The ranges
are from 1 to 2147483647; the default is 100.
Rising Event Specify the index of the event that will be triggered when the sampled value
exceeds the preset threshold.
Falling Threshold Set the falling threshold of the variable. When the sampled value is below
the threshold, the system will trigger the corresponding Falling Event. The
ranges are from 1 to 2147483647; the default is 100.
Falling Event Specify the index of the event that will be triggered when the sampled value is
below the preset threshold.
