4.10.1.7.3 Switch RMON Alarm Configuration

Configure the RMON Alarm table on the RMON Alarm Configuration page, as shown in the following figure. The entry index key is ID.

Figure 4-35. RMON Alarm Configuration

The RMON Alarm Configuration page has the following parameters:

  • Delete: Check to delete the entry. It is deleted during the next save.
  • ID: Indicates the index of the entry. The range is from 1–65535.
  • Interval: Indicates the interval in seconds for sampling and comparing the rising and falling threshold. The range is from 1 to 2^31-1.
  • Variable: Indicates the variable to be sampled. The following is the list of possible variables.
    • InOctets: The total number of octets received on the interface, including framing characters
    • InUcastPkts: The number of uni-cast packets delivered to a higher-layer protocol
    • InNUcastPkts: The number of broad-cast and multi-cast packets delivered to a higher-layer protocol
    • InDiscards: The number of inbound packets that are discarded even if the packets are normal
    • InErrors: The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol
    • InUnknownProtos: The number of the inbound packets that were discarded because of the unknown or un-support protocol
    • OutOctets: The number of octets transmitted out of the interface, including framing characters
    • OutUcastPkts: The number of uni-cast packets that request to transmit
    • OutNUcastPkts: The number of broadcast and multicast packets that request to transmit
    • OutDiscards: The number of outbound packets that are discarded even if the packets are normal
    • OutErrors: The number of outbound packets that could not be transmitted because of errors
    • OutQLen: The length of the output packet queue (in packets)
  • Sample Type: The method of sampling the selected variable and calculating the value to be compared against the thresholds. The following is the list of sample types.
    • Absolute: Get the sample directly
    • Delta: Calculate the difference between samples (default)
  • Value: The value of the statistics during the last sampling period
  • Startup Alarm: The method of sampling the selected variable and calculating the value to be compared against the thresholds. The following is the list of sample types.
    • Rising: Trigger alarm when the first value is larger than the rising threshold
    • Falling: Trigger alarm when the first value is less than the falling threshold
    • RisingOrFalling: Trigger alarm when the first value is larger than the rising threshold or less than the falling threshold (default).
  • Rising Threshold: Rising threshold value (−2147483648 to 2147483647)
  • Rising Index: Rising event index (0–65535). If this value is zero, then no associated event is generated, as zero is not a valid event index.
  • Falling Threshold: Falling threshold value (−2147483648 to 2147483647)
  • Falling Index: Falling event index (0–65535). If this value is zero, no associated event is generated, as zero is not a valid event index.
