Configuring Attack Detectors
Step 1 From the SCE(config if)# prompt, type attack-detector default protocol (((TCP|UDP) [dest-port
(specific|not- specific|both)]) |ICMP|other|all) attack-direction
(single-side-source|single-side-destination|single-side-both|dual-sided|all) side
(subscriber|network|both) [action (report|block)] [open-flows-rate
number suspected-flows-rate
rate suspected-flows-ratio
ratio] and press Enter.
Configures the default attack detector for the defined attack type.
Step 2 From the SCE(config if)# prompt, type attack-detector default protocol (((TCP|UDP) [dest-port
(specific|not- specific|both)])|ICMP|other|all) attack-direction
(single-side-source|single-side-destination|single-side-both|dual-sided|all) side
(subscriber|network|both) (notify-subscriber|don't-notify-subscriber)
and press Enter.
Enables or disables subscriber notification by default for the defined attack type.
The attack type must be defined the same as in Step 1.
Step 3 From the SCE(config if)# prompt, type attack-detector default protocol (((TCP|UDP) [dest-port
(specific|not- specific|both)]) |ICMP|other|all) attack-direction
(single-side-source|single-side-destination|single-side-both|dual-sided|all) side
(subscriber|network|both) (alarm|no-alarm) and press Enter.
Enables or disables sending an SNMP trap by default for the defined attack type.
The attack type must be defined the same as in Step 1.
How to Reinstate the System Defaults for a Selected Set of Attack Types
Use the following command to delete user-defined default values for action, thresholds, subscriber
notification, and sending an SNMP trap for a selected set of attack types, and reinstate the system
defaults.
Step 1 From the SCE(config if)# prompt, type default attack-detector default protocol (((TCP|UDP)
[dest-port (specific|not- specific|both)])|ICMP|other|all) attack-direction
(single-side-source|single-side-destination|single-side-both|dual-sided|all) side
(subscriber|network|both) and press Enter.
Reinstates the system defaults for the defined attack types.
How to Reinstate the System Defaults for All Attack Types
Step 1 From the SCE(config if)# prompt, type default attack-detector default and press Enter.
Reinstates the system defaults for the defined attack types.
