What is axSwitchStatsAnomTCPSynFinDrop?
This OID counts packets with both TCP SYN and FIN flags set, an impossible state during normal connection flow. These malformed packets are dropped to prevent stack fingerprinting and bypass attacks. A count of 100 per day indicates the anomaly filter is catching craftily formatted reconnaissance packets, protecting against evasion techniques.
