Reference Guide

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
packets’ 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 Z9500 Configuration Guide.
The software cannot count both packets and bytes, so when you enter the count byte options, only bytes
are incremented.
