Usage Information
When you use the log option, the CP processor logs detail the packets that match. Depending on how many
packets match the log entry and at what rate, the CP may become busy as it has to log these packet details.
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.
Use the monitor option only when you are using flow-based monitoring. For more information, refer to the Port
Monitoring chapter of the C9000 Series Configuration Guide.
NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may
display an incorrect value. Configure packet counters with logging instead.

IP Prefix List Commands
When you create an access-list without any rule and then apply it to an interface, the ACL behavior reflects implicit permit.
To configure or enable IP prefix lists, use these commands.
clear ip prefix-list
Reset the number of times traffic meets the conditions (“hit” counters) of the configured prefix lists.
