agDosPortStatsAckZero
Module: ALTEON-CHEETAH-SWITCH-MIB
OID (symbolic): ALTEON-CHEETAH-SWITCH-MIB::agDosPortStatsAckZero
OID (numeric): 1.3.6.1.4.1.1872.2.5.1.2.6.1.1.43
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: TCP packets with acknowledgement number is zero and ACK bit is set.
What is agDosPortStatsAckZero?
This Counter32 counts TCP packets with ACK bit set but acknowledgment number is 0—a protocol anomaly. Network engineers watch this to detect packets designed to confuse TCP reassembly engines. Example: presence in external traffic indicates attack sophistication targeting stateful inspection.
