Excessive BOOTP
Counter
The Excessive BOOTP counter increments when a change in the number of
BOOTP/DHCP requests per second exceeds a threshold. A count of all Excessive
BOOTP events displays in the
Overview counters of Expert View. A threshold for
this counter can be set in Expert Alarms.
Expert Symptom
Excessive BOOTP events are automatically logged as expert symptoms. The
Symptom Summary field provides information about the rate of change for BOOTP/
DHCP requests. For example:
Rate of change of Bootp/Dhcp Requests=25
The threshold value for this symptom can be changed. The default threshold is a
delta of 10 BOOTP/DHCP requests per second.
