alarmFalling-<br />

Threshold<br />

rmon<br />

An Ethernet statistical variable<br />

has dipped below its falling<br />

threshold. The variable’s falling<br />

threshold and whether it will<br />

issue an SNMP trap for this condition<br />

are configured by an NMS<br />

station running RMON.<br />

alarmIndex—An index that uniquely identifies an entry in the alarm table. Each such entry defines a diagnostic<br />

sample at a particular interval for an object on the device.<br />

alarmVariable—The object identifier of the particular variable to be sampled. Only variables that resolve to an<br />

ASN.1 primitive type of INTEGER (INTEGER, Integer32, Counter32, Counter64, Gauge, or TimeTicks) may<br />

be sampled.<br />

alarmSampleType—The method of sampling the selected variable and calculating the value to be compared<br />

against the thresholds. If the value of this object is absoluteValue (1), the value of the selected variable will be<br />

compared directly with the thresholds at the end of the sampling interval. If the value of this object is deltaValue<br />

(2), the value of the selected variable at the last sample will be subtracted from the current value, and the difference<br />

compared with the thresholds.<br />

alarmValue—The value of the statistic during the last sampling period. For example, if the sample type is deltaValue,<br />

this value will be the difference between the samples at the beginning and end of the period. If the sample<br />

type is absoluteValue, this value will be the sampled value at the end of the period.<br />

alarmFallingThreshold—A threshold for the sampled statistic. When the current sampled value is less than or<br />

equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single event<br />

will be generated. A single event will also be generated if the first sample after this entry becomes valid is less<br />

than or equal to this threshold and the associated alarmStartupAlarm is equal to fallingAlarm (2) or risingOr-<br />

FallingAlarm (3).<br />

24 stpNewRoot vStpNumber stp Sent by a bridge that became the<br />

new root of the spanning tree.<br />

vStpNumber—The Spanning Tree number identifying this instance.<br />

25 stpRootPortChange vStpNumber<br />

vStpRootPort-<br />

Number<br />

stp<br />

A root port has changed for a<br />

spanning tree bridge. The root<br />

port is the port that offers the<br />

lowest cost path from this bridge<br />

to the root bridge.<br />

vStpNumber—The Spanning Tree number identifying this instance.<br />

vStpRootPortNumber—The port ifindex of the port which offers the lowest cost path from this bridge to the<br />

root bridge for this spanning tree instance.<br />

26 mirrorConfigError mirmonPrimarySlot<br />

mirmonPrimaryPort<br />

mirroringSlot<br />

mirroringPort<br />

mirMonErrorNi<br />

mirMonError<br />

pmm<br />

The mirroring configuration<br />

failed on an NI. This trap is sent<br />

when any NI fails to configure<br />

mirroring. Due to this error, port<br />

mirroring session will be terminated.<br />

mirmonPrimarySlot—Slot of mirrored or monitored interface.<br />

mirmonPrimaryPort—Port of mirrored or monitored interface.<br />

mirroringSlot—Slot of mirroring interface.<br />

mirroringPort—Port of mirroring interface.<br />

mirMonErrorNi—The NI slot number.<br />

mirMonError—The Error returned by the NI which failed to configure Mirroring/Monitoring.<br />
