What is h3cAclIPAclAdvancedTCPFlagMask?
This OID is a bitmask (BITS field) specifying which TCP flags to examine: ACK, FIN, PSH, RST, SYN, or URG. Network engineers set it to focus on relevant flags; examining only SYN avoids false matches on data-carrying packets. A mask of 0x02 (SYN only) detects connection initiation regardless of other flags.
