(RFC 1757)
HdevLastTrapString
(devHealthAndStatus.-
mib)
Object being monitored has risen
above the set threshold.
String:
‘Change in $variableName
$typeString threshold of
$alarmRisingThreshold by
$(alarmValue –
alarmRisingThreshold.’
(e.g., ‘Octets received on Sync
Data Port S01P1 frame relay

if alarmValue equals
alarmRisingThreshold;
otherwise, it is ’exceeded’.
