When the percentage of total DNS-learnt IPv6 entries goes below the low threshold, the
ECSTotalDNSLearntIPv6ThresholdClear trap is generated.
ECSTotalDNSLearntIPv6ThresholdClear trap is generated.
low_thresh
is an integer value from 0 through 100. When configured to 0 the threshold is disabled.
Important:
This value is ignored for the Alert model. In addition, if this value is not configured for the Alarm
model, the system assumes it is identical to the low threshold.
Usage
Use this command to configure thresholds for the percentage of total DNS-learnt IP entries in relation to the
ACS DNS Snooping feature. Note that this threshold applies to both IPv4 and IPv6 DNS entries.
Alerts or alarms are triggered based on the following rules:
ACS DNS Snooping feature. Note that this threshold applies to both IPv4 and IPv6 DNS entries.
Alerts or alarms are triggered based on the following rules:
Enter condition: Actual percentage of total DNS-learnt IP entries is greater than or equal to the
specified percentage of total DNS-learnt IP entries.
Clear condition: Actual of total DNS-learnt IP entries is less than the specified clear percentage of
total DNS-learnt IP entries.
If a trigger condition exists at the end of the polling interval, the alert or alarm will not be generated until the
end of the polling interval.
Refer to the
end of the polling interval.
Refer to the
threshold poll
command to configure the polling interval, and the
threshold
monitoring
command to enable thresholding for this value.
Example
The following command configures a high threshold of
65
percent and a clear threshold of
35
percent for
total DNS-learnt IP entries:
threshold dns-learnt-ip-max-entries 65 clear 35
