Configuring the Switch

Statistics > RMON Alarms

The RMON Alarms screen allows you to record important events and critical network problems.. The RMON Alarm and Event Control Tables are used together to define specific criteria that will generate response events..

Alarms can be set to test data over any specified time interval and can monitor absolute or changing values, such as a statistical counter reaching a specific value, or a statistic changing by a certain amount over a set interval.. Alarms can be set to respond to either rising or falling thresholds..

Statistics > RMON Alarms

The Alarm Control Table allows you to add, update and delete specific index entries..

Interface  The selected interface on the Switch..

Statistics  The traffic statistics to be sampled.. Select from the drop-down list..

Interval  The time interval in seconds over which data is sampled and compared with the rising or falling threshold..

Sample Type  The method of sampling data, either Absolute or Delta.. For an absolute sample the variable will be compared directly to the thresholds.. For a delta sample the last sample is subtracted from the current value and the difference is then compared to the thresholds..

Startup Alarm  How the alarm is activated when the variable is compared to the thresholds.. This can be set to Rising, Falling, or Rising or Falling..

Rising Threshold  An alarm threshold for the sampled variable.. If the current value is greater than or equal to the threshold, and the last sample value was less than the threshold, then an alarm will be generated.. (After a rising event has been generated, another such event will not be generated until the sampled value has fallen below the Rising Threshold and reaches the Falling Threshold..)

Falling Threshold  An alarm threshold for the sampled variable.. If the current value is less than or equal to the threshold, and the last sample value was greater than the threshold, then an alarm will be generated.. (After a falling event has been generated, another such event will not be generated until the sampled value has risen above the Falling Threshold and reaches the Rising Threshold..)

Rising Event Index (0-65535)  The index of the Event that will be used if a rising alarm is triggered.. If there is no corresponding entry in the Event Control Table, or if this number is zero, then no event will be generated..

Falling Event Index (0-65535)  The index of the Event that will be used if a falling alarm is triggered.. If there is no corresponding entry in the Event Control Table, or if this number is zero, then no event will be generated..

Owner  The name of the person who created this entry in the Control Table..

Statistics > RMON Events

An RMON Event determines the action to take when an alarm is triggered.. The response to an alarm can include logging the alarm or sending an SNMP trap message.. If the response corresponding to an alarm has not yet been defined, use the RMON Event screen to configure the Event Setting table..
