Virtual Server Syncookie Status

I was just reading SOL14805 about Configuring Syncookie protection. All my virtual servers are using the TCP WAN Optimized profile on the client side, which has Hardware SYN Cookie Protection enabled. However when I look at my Virtual Servers, they all say Syncookie Status Off. Is this normal? Does that just mean it hasn't been activated? Or its not enabled? Just curious.

    From my reading of Sol 14805, the value of the 'Syncookie Status' is not an indication of the feature being configured or enabled, but rather if the feature is in use. In other words, if your device isn't under SYN-Flood, the Syncookie Status of a virtual server will always be off.

     

    The wording is a bit confusing, I have to admit: "Off: The SYN cookie feature is not currently active for the virtual server."
