RMON

RMON > Basic Settings

• RMON Status Map Name—select the RMON status of the switch. The default is Disabled. The drop-down list contains:
  • Enabled—enables RMON in the switch.
  • Disabled—disables RMON of the switch. When disabled, the RMON’s network monitoring is called off.

• Apply—modifies attributes and saves the changes.

RMON > Alarms

• Select—select the index to modify the attributes of the selected entry.
• Index—enter the value of RMON alarm table index. The index value uniquely identifies an entry in the alarm table. Each such entry defines a diagnostic sample at a particular level for a MIB object in the device. This value ranges from 1 to 65535.
• Interval—enter the time interval in seconds for which the alarm monitors the MIB object variable. It is during this interval the data is sampled and compared with the rising and falling thresholds. This value ranges from 1 to 65535.
• Variable—enter the MIB object variable for which the alarm is set. For successful configuration, the variable has to be a valid Object ID.

• Sample Type—select the sample type to be compared against the thresholds. The default option is Absolute value. The list contains:

• • Absolute value—compares the value of the selected variable directly with the thresholds at the end of the sampling interval.
  • Delta value—subtracts the value of the selected variable at the last sample from the current value and compares the difference with the thresholds at the end of the sampling interval.
• Rising Threshold—enter the Rising Threshold value. This value ranges from 0 to 2147483647.
  Note:

  If the start-up alarm is set as Rising alarm or Rising Or Falling alarm and if the configured threshold value is reached, then an alarm is raised.When the current sampled value is greater than or equal to the configured Rising threshold, and the value at the last sampling interval is less than this configured threshold, a single event will be generated.

• Falling Threshold—enter the Falling Threshold value. This value ranges from 0 to 2147483647.
  Note: The Falling Threshold value should be lesser than the Rising threshold value.If the start-up alarm is set as Falling alarm or Rising Or Falling alarm and if the configured threshold value is reached, then an alarm is raised.When the current sampled value is lesser than or equal to the configured Falling threshold, and the value at the last sampling interval is greater than this threshold, a single event will be generated.
• Rising Event Index—enter the index of the event to be raised when the Rising threshold is reached. This value ranges from 1 to 65535.
  Note: The value of this field is same as Event Index in RMON Events Configuration.
• Falling Event Index—enter the index of the event to be raised when the Falling threshold is reached. This value ranges from 1 to 65535.
  Note: The value of this field is same as Event Index in RMON Events Configuration.
• Owner—enter the entity details that configured this entry and is using the resources assigned to it.
• Alarm Value—displays the value of the statistic during the last sampling period. This value remains available until the current sampling period is completed. For example, if the sample type is deltaValue, this value will be the difference between the samples at the beginning and end of the period. If the sample type is absoluteValue, this value will be the sampled value at the end of the period. This value is compared with the rising and falling thresholds.
• Startup Alarm—displays the alarm that is sent when the entry is set as valid for the first time. The list contains:
  • RisingAlarm—denotes that the first sample after the entry becoming valid is greater than or equal to the rising threshold.
  • FallingAlarm—denotes that the first sample after the entry becoming valid is less than or equal to the falling threshold.
  • RisingOrFallingAlarm—denotes that either Rising or Falling Alarm is sent based on the sample in comparison with the rising and falling threshold.

• Status—select the required status of alarm. The list contains:
  • Valid—sets the status as Valid if the entry is completely created.
  • Under Creation—sets the status as Under Creation if the entry is created and not completely configured
  • Entries in this state are not fully active. Entries exists in the “Under Creation” state until the management station has finished configuring the entry and sets this object to valid or invalid state.
  • Invalid—sets the status as Invalid if the entry is removed. It also effectively disassociates the mapping identified with the entry.
  Note:

  While creating a new RMON alarm entry, for invalid configurations, an error message is displayed, and the status is set as Under Creation.

RMON > Ethernet Statistics

• Select—select the index to modify the attributes of the selected entry.
• Index—enter the Ethernet Statistics index that uniquely identifies an entry in the Ethernet Statistics table. This value ranges from 1 to 65535.

• Data Source—enter the SMNP object ID of the variable on which the statistics is being collected. This object identifies the instance of the ifIndex object. For successful configuration the Data Source has to be a valid Object ID.
  Note:

  For e.g. 1.3.6.1.2.1.2.2.1.1.1 Index or 1.3.6.1.2.1.17.7.1.4.2.1.2.1 Index. Here, the value of Index depends upon the number of ports/VLAN created.

• Owner—enter the details of the entity that configured this entry and is using the resources assigned to it.
• Drop Events—displays the number of events in which the packets were dropped by the probe due to lack of resources. This number does not specify the number of packets dropped but the number of times the packets were dropped
• Octets—displays the total number of octets of data received from the network (excluding the framing bits but including FCS octets). This can be used as a reasonable estimate of 10-Megabit Ethernet utilization.
• Packets—displays the total number of packets received from the network. This includes bad packets, broadcast packets and multicast packets received.
• Broadcast Packets—displays the total number of packets received that were directed to the broadcast address.
• Multicast Packets—displays the total number of packets that were directed to the multicast address.
• Status—select the required status of event. The list contains:
  • Valid—sets the status as Valid if the entry is completely created.
  • Under Creation—sets the status as Under Creation if the entry is created and not completely configure
    Note:

    Entries in this state are not fully active. Entries exists in the Under Creation state until the management station has finished configuring the entry and sets this object to valid or invalid state.

  • Invalid—sets the status as Invalid if the entry is removed. It also effectively disassociates the mapping identified with the entry.

• Description—enter a brief description of the event—a string of maximum size 127.
  Note:

  This field value accepts only Characters and number.

• Type—select the type of event to be configured. This is the type of notification that the probe makes about this event. The list contains:

  • SNMP Trap—sends an SMNP trap to one or more management stations.
  • Log and Trap—creates an entry in the log table and sends an SMNP trap.
  • None—sets the event type as None—no notifications are sent.
  Note:

  This field value accepts only Characters and number.
