Object

column r/w SNMPv2-TCInstancePointer

The object identifier of the particular variable
to be sampled.  Only variables that resolve to an
ASN.1 primitive type of INTEGER (Integer32,
Counter32, Gauge32, TimeTicks, Counter64, or
UInteger32) may be sampled.
              
If it is detected by an error response of
authorizationError, noSuchObject, or
noSuchInstance that the variable name of an
established snmpAlarmEntry is no longer available
in the sampling context, a single
snmpObjectUnavailableAlarm event is generated and
the status of this snmpAlarmEntry is set to
`destroy'.  Likewise, if the syntax of the
variable retrieved by the query is not Integer32,
Counter32, Gauge32, TimeTicks, Counter64, or
UInteger32, the same actions will be taken.
              
If the SNMPv2 entity acting in a dual role detects
that the sampled value can not be obtained due to
lack of response to management queries, it should
either:
              
     1) Set the status of this snmpAlarmEntry to
     `destroy', if it is determined that further
     communication is not possible;
              
     or,
     2) Delete the associated snmpAlarmValue
     instance (but not the entire conceptual row),
     and continue to attempt to sample the
     variable and recreate the associated
     snmpAlarmValue instance should communication
     be reestablished.
              
An attempt to modify this object will fail with an
`inconsistentValue' error if the associated
snmpAlarmStatus object would be equal to `active'
both before and after the modification attempt.
