agDosPortStatsSYNFrag
Module: ALTEON-CHEETAH-SWITCH-MIB
OID (symbolic): ALTEON-CHEETAH-SWITCH-MIB::agDosPortStatsSYNFrag
OID (numeric): 1.3.6.1.4.1.1872.2.5.1.2.6.1.1.39
Node type: OBJECT-TYPE

Description: TCP packets with SYN bit is set and more fragments bit is set.
What is agDosPortStatsSYNFrag?
This Counter32 counts TCP SYN packets with the more-fragments flag set—a rare, suspicious combination. Network engineers use this to detect fragmentation-based evasion of stateful inspection. Example: any counts typically indicate either broken endpoints or intentional attack traffic.
