Monitoring Attack Filtering
•
Monitoring Attack Filtering Using SNMP Traps, page 10-20
•
Monitoring Attack Filtering Using CLI Commands, page 10-22
•
Viewing the Attack Log, page 10-28
There are three options for monitoring attack filtering and detection:
•
CLI show commands
•
SNMP attack detection traps
•
Attack log
Monitoring Attack Filtering Using SNMP Traps
The system sends a trap at the start of a specific attack detection event, and also when a specific detection
event ends, as follows:
•
STARTED_FILTERING trap – String with the attack information
•
STOPPED_FILTERING
–
String with the attack information
–
String with the reason for stopping
