Version Description
7.4.1.0 Added support for the non-contiguous mask and added the monitor option. Deprecated
the keyword established.
6.5.10 Expanded to include the optional QoS order priority for the ACL entry.
Usage Information
If you configure the sequence-number, the sequence-number is used as a tie breaker for rules with the
same order.
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. The following conditions apply:
•
The seq sequence-number command is applicable only in an ACL group.
• The order option works across ACL groups that have been applied on an interface via the QoS policy
framework.
• The order option takes precedence over seq sequence-number.
• If sequence-number is not configured, the rules with the same order value are ordered according to their
configuration order.
• If sequence-number is configured, the sequence-number is used as a tie breaker for rules with the same
order.
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.
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.
NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may
display an incorrect value. Configure packet counters with logging instead.
