By default, 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which ACL logs are generated is five minutes. By default,
flow-based monitoring is not enabled.
The
monitor
option is relevant in the context of flow-based monitoring only. For
more information, refer to
Port Monitoring
.
NOTE: When ACL logging and byte counters are configured simultaneously,
byte counters may display an incorrect value. Configure packet counters with
logging instead.
permit tcp
To pass TCP packets meeting the filter criteria, configure a filter.
