Usage
Use the order option only when you use policy-based QoS on the switch. For
Information
more information, refer to the Quality of Service chapter in the Z9500
Configuration 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 packet details.
Use the monitor option only when you are using flow-based monitoring. For
more information, refer to the Port Monitoring chapter in the Z9500 Configuration
Guide.
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.
Most ACL rules require one entry in the CAM. However, rules with TCP and UDP
port operators (for example, gt, lt, or range) may require more than one entry. The
range of ports is configured in the CAM based on bit mask boundaries; the space
required depends on exactly what ports are included in the range.
Example
An ACL rule with a TCP port range of 4000–8000 uses eight entries in the CAM.
