From the SCE(config if)# prompt, type:
Specific Attack Detectors
Use these commands to define thresholds, actions, subscriber notification setting, and sending an SNMP
trap for a specific attack detector for selected set of attack types.

Options
A specific attack detector may be configured for each possible combination of protocol, attack direction,
and side. The Cisco SCE platform supports a maximum of 100 attack detectors. Each attack detector is
identified by a number (1-100). Each detector can be either disabled (default) or enabled. An enabled
attack detector must be configured with the following parameters:
•
access-list—
The number of the Access-Control List (ACL) associated with the specified attack
detector. The ACL identifies the IP addresses selected by this detector. (See
Control Lists (ACLs)” section on page 5-32
–
For dual-ip detections, the destination IP address is used for matching with the ACL.
–
Use the "none" keyword to indicate that all IP addresses are permitted by this attack-detector.
This option is useful when using the command to define a port list, and the desired configuration
should be set for all IP addresses.
