Packets are logged only when they go to the CPU, so packets in the fastpath are not automatically logged. You must use both the mirror-cpu action modifier and the log or log-raw action modifier if you want to log both slowpath and fastpath packets that match the ACL rule entry. Additionally, Kern.Info messages (or Kern.Card.Info on SummitStack) are not logged by default. You must configure an EMS filter to log these messages, for example, configure log filter DefaultFilter add event kern.info. See the Status Monitoring and Statistics chapter for information about configuring EMS.
