What is bigipAsmDosAttackDetected?
This OID triggers an alert notification when F5's application security system detects a denial-of-service (DoS) attack. It indicates that the security module is actively blocking traffic it believes is part of a coordinated attack designed to overload the system. An operator would subscribe to this alert to be notified in real time when their application is under attack, so they can escalate or implement additional defenses.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' F5-BIGIP-COMMON-MIB::bigipAsmDosAttackDetected snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.3375.2.4.0.91
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
