Step 8 Set the scanner threshold.
sensor(config-ano-ill-tcp-dst-yes)# scanner-threshold 100
Step 9 Configure the default thresholds for all other unspecified ports.
sensor(config-ano-ill-tcp-dst-yes)# exit
sensor(config-ano-ill-tcp-dst)# exit
sensor(config-ano-ill-tcp)# exit
sensor(config-ano-ill-tcp)# default-thresholds
sensor(config-ano-ill-tcp-def)# default-thresholds
sensor(config-ano-ill-tcp-def)# threshold-histogram medium num-source-ips 120
sensor(config-ano-ill-tcp-def)# scanner-threshold 120
Step 10 Verify the TCP configuration settings.
sensor(config-ano-ill-tcp)# show settings
