8.1.1.0 Introduced on the E-Series ExaScale.

Usage
Information
Use the order option only when you use policy-based QoS on the switch. For more information, refer to
the Quality of Service chapter of the C9000 Series 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
packets’ details.
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.
