rmon hcalarm Chapter 20 R Commands Send documentation comments to [email protected] Usage Guidelines Event number 0 is a predefined null (or no operation) event. When no event is specified by the user in an alarm this event is automatically used by the system. The event causes no action to be taken when triggered, however, the alarm is still reset. The event cannot be redefined by the user. It is a predefined event and you can only create events in the range from 1 to 65535. To configure a high-capacity RMON alarm, use the CISCO-HC-ALARM-MIB. The maximum number of RMON alarms is currently configurable through the device manager and threshold manager GUI. A CLI command is not available to change this maximum value. Note We recommand setting alarm sample intervals to 30 seconds or higher to prevent excessive load on the system. Examples The following example configures 64-bit alarm number 2 for ifHCInOctets (OID 1.3.6.1.2.1.31.1.1.1.6) on interface fc 12/1. The sample interval is 30 seconds and delta samples are tested. The rising threshold is 240,000,000,000 bytes per sample window (an average of 8,000,000,000 bytes per second); reaching this level triggers event 4. The falling threshold is 180,000,000,000 bytes in the sample window (an average of 6,000,000,000 bytes per second) which triggers event 0 (no action) and resets the alarm. The owner is 'ifHCInOctets.fc12/1@test'. switch#config terminal switch#(config) rmon hcalarm 2 1.3.6.1.2.1.31.1.1.1.6.22544384 30 delta rising-threshold-high 55 rising-threshold-low 3776798720 4 falling-threshold-high 41 falling-threshold-low 3906340864 owner ifHCInOctets.fc12/1@test Related Commands Command rmon alarm rmon hcalarm rmon event show rmon show snmp host snmp-server host Description Configures a 32-bit RMON alarm.
