Description: This variable indicates whether or not TCP segments whose ACK bit is off are allowed to use an existing flow table entry. When set to 2, a TCP segment whose ACK bit is off is always treated as an exception packet. This variable takes effect immediately, and its value is peristent.
What is sfpsL4CPDisableTCPAckCheck?
Controls whether a TCP segment whose ACK bit is off is always treated as an exception packet (no(2)) or is allowed to reuse an existing flow-table entry (yes(1)); per the source description the change takes effect immediately and persists across reboots. An admin might set this on a Layer 4 Smart Switch that sees legitimate ACK-less TCP segments (e.g. from certain load balancers) being wrongly punted to the exception path.
