What is axSwitchStatAnomTCPNoFragDrop?
This Counter32 tracks TCP packets dropped for missing expected flags (typically packets with no TCP flags set, indicating malformed segments). This helps identify crafted TCP packets used in flood attacks or reconnaissance. A jump to 50000 drops in seconds suggests a TCP flag-based DDoS attack is being mitigated automatically.
