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
Z9500
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.
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.
