Configuration Examples for Threat Detection
The following example configures basic threat detection statistics, and changes the DoS attack rate
settings. All advanced threat detection statistics are enabled, with the host statistics number of rate
intervals lowered to 2. The TCP Intercept rate interval is also customized. Scanning threat detection is
enabled with automatic shunning for all addresses except 10.1.1.0/24. The scanning threat rate intervals
are customized.

threat-detection rate scanning-threat rate-interval 1200 average-rate 10 burst-rate 20
threat-detection rate scanning-threat rate-interval 2400 average-rate 10 burst-rate 20
Burst rate interval changed to 1/30th of the
average rate.
8.2(1) In earlier releases, the burst rate interval was 1/60th of the
average rate. To maximize memory usage, the sampling
interval was reduced to 30 times during the average rate.
Improved memory usage 8.3(1) The memory usage for threat detection was improved.
