Configuring RMON Alarm Functions

Configuring RMON Alarm Functions

Context

RMON alarm functions include event definition function and alarm threshold setting function.

To monitor the system running status, configure the alarm threshold setting function. When an error occurs in the system, the related event is triggered. The event definition function can determine whether to log the event or send a trap to the NMS.

NOTE:

If the alarm variables configured in RMON alarm function are MIB variables defined in the statistics group or history group, the Ethernet statistics function or history statistics function must be configured on the monitored Ethernet interface first.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Configure event definition function.

    Run the rmon event entry-number [ description string ] { log | trap object | log-trap object | none } [ owner owner-name ] command to create an event table and add an entry to the table.

  3. Configure alarm threshold function.

    (Optional) Run the snmp-agent trap enable feature-name rmon [ trap-name { fallingalarm | risingalarm | rmon_pri_fallingalarm | rmon_pri_risingalarm } ] command to enable the alarm function for the RMON module.

    By default, all alarms for the RMON module are enabled. If only one or some event alarms need to be enabled, run the snmp-agent trap enable feature-name rmon trap-name command.

    1. Run the rmon alarm entry-number alarm-OID sampling-time { absolute | changeratio | delta } rising-threshold threshold-value1 event-entry1 falling-threshold threshold-value2 event-entry2 [ owner owner-name ] command to create an alarm table and add an entry to the table.
    2. Run the rmon prialarm entry-number prialarm-formula description-string sampling-interval { absolute | changeratio | delta } rising-threshold threshold-value1 event-entry1 falling-threshold threshold-value2 event-entry2 entrytype { cycle entry-period | forever } [ owner owner-name ] command to create an extended alarm table and add an entry to the table.

      If the events (event-entry1, event-entry2) corresponding to alarm rising threshold and falling threshold are not configured in the event table, no alarm will be generated even if the alarm conditions are met. In this situation, the alarm record status is undercreation, but not valid.

      After either of the events is configured, the alarm will be generated when the alarm conditions are met and the alarm status is valid. If an incorrect alarm variable is created, for example, an inexistent OID is specified, the alarm is in the undercreation state and no alarm is generated.
