RMON Configurations
User Guide 1073
Configuring SNMP & RMON
Follow these steps to configure the Alarm group:
1) Select an alarm entry, choose a variable to be monitored, and associate the entry with a
statistics entry.
Index Displays the index of Alarm entries. The switch supports up to 12 Alarm
entries.
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.
RecBytes: Total number of received bytes.
RecPackets: Total number of received packets.
BPackets: Total number of broadcast packets.
MPackets: Total number of multicast packets.
CRC&Align ERR: Packets that contain FCS Error or Alignment Error, within a
size of 64 to 1518 bytes.
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, 1024-1518: Total number of
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 entries,
and the alarm type of the entry.
Sample Type Specify the sampling method of the specified variable.
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 Specify the rising threshold of the variable. Valid values are from 1 to
2147483647. When the sampling value or the difference value exceeds the
threshold, the system will trigger the corresponding Rising Event.
Note:
The rising threshold should be larger than the falling threshold.
Rising Event Specify the index of the Event entry that will be triggered when the sampling
value or the difference value exceeds the preset threshold. The Event entry
specified here should be enabled first.
