threshold dns-learnt-ip-max-entries high_thresh [ clear low_thresh ]
default threshold dns-learnt-ip-max-entries
default
Configures this command with the default threshold setting.
Default: 90 percent. It is the same for both high and low thresholds.
Default: 90 percent. It is the same for both high and low thresholds.
high_thresh
Default: 90 percent
Specifies the high threshold for percentage of total DNS-learnt IP entries. When the percentage of total DNS-
learnt IP entries meets or exceeds the high threshold at the end of the polling interval, an alert or alarm is
generated.
When the percentage of total DNS-learnt IPv4 entries meets or exceeds the high threshold, the
ECSTotalDNSLearntIPv4Threshold trap is generated.
When the percentage of total DNS-learnt IPv6 entries meets or exceeds the high threshold, the
ECSTotalDNSLearntIPv6Threshold trap is generated.
Specifies the high threshold for percentage of total DNS-learnt IP entries. When the percentage of total DNS-
learnt IP entries meets or exceeds the high threshold at the end of the polling interval, an alert or alarm is
generated.
When the percentage of total DNS-learnt IPv4 entries meets or exceeds the high threshold, the
ECSTotalDNSLearntIPv4Threshold trap is generated.
When the percentage of total DNS-learnt IPv6 entries meets or exceeds the high threshold, the
ECSTotalDNSLearntIPv6Threshold trap is generated.
high_thresh
is an integer value from 0 through 100. When configured to 0 the threshold is disabled.
clear low_thresh
Default: 90 percent
Specifies the low threshold for percentage of total DNS-learnt IP entries. When the percentage of total DNS-
learnt IP entries goes below the low threshold within the polling interval, a clear alarm is generated.
When the percentage of total DNS-learnt IPv4 entries goes below the low threshold, the
ECSTotalDNSLearntIPv4ThresholdClear trap is generated.
When the percentage of total DNS-learnt IPv6 entries goes below the low threshold, the
ECSTotalDNSLearntIPv6ThresholdClear trap is generated.
Specifies the low threshold for percentage of total DNS-learnt IP entries. When the percentage of total DNS-
learnt IP entries goes below the low threshold within the polling interval, a clear alarm is generated.
When the percentage of total DNS-learnt IPv4 entries goes below the low threshold, the
ECSTotalDNSLearntIPv4ThresholdClear trap is generated.
When the percentage of total DNS-learnt IPv6 entries goes below the low threshold, the
ECSTotalDNSLearntIPv6ThresholdClear trap is generated.
low_thresh
is an integer value from 0 through 100. When configured to 0 the threshold is disabled.
