Why does the Selective-ACK-Permitted option is enabled by default?
On FWSM running 3.2 OS, the sysopt connectione tcp sack-permitted is enabled by default. Because of the tcp randomization that is enabled too by default the tcp selective acknowledge feature is not usefull. I'm planning too disable the tcp-sack using the no sysopt command. Usually, OS default configuration are consistant. Am I missing something here?
