extremeIpSecurityAnomalyL4PortViolation
Module: EXTREME-IP-SECURITY-MIB
OID (symbolic): EXTREME-IP-SECURITY-MIB::extremeIpSecurityAnomalyL4PortViolation
OID (numeric): 1.3.6.1.4.1.1916.1.34.2.0.2
Node type: NOTIFICATION-TYPE
Description: For ports on which the protocol anomaly protection L4port features has been enabled, this trap will be generated when a packet received on that port if 1) the packet is a TCP or UDP packetr. AND 2) its source L4 port == destination port
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> '' EXTREME-IP-SECURITY-MIB::extremeIpSecurityAnomalyL4PortViolation snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1916.1.34.2.0.2
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
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:51347->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (392156819) 45 days, 9:19:28.19 SNMPv2-MIB::snmpTrapOID.0 = OID: EXTREME-IP-SECURITY-MIB::extremeIpSecurityAnomalyL4PortViolation
