Usage guidelines
After you enable Naptha attack prevention, the device periodically checks the number of TCP connections in each state. If the number of TCP connections in a state exceeds the limit, the device will accelerate the aging of the TCP connections in that state. The check interval is set by the tcp check-state interval command. The TCP connection limits are set by the tcp state command.
