Information
The monitor option is relevant in the context of the flow-based monitoring feature only. See
Chapter 45, Port Monitoring.
When you use the log option, CP processor logs details about 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.
The order option is relevant in the context of the Policy QoS feature only. The following applies:
• The seq sequence-number is applicable only in an ACL group.
• The order option works across ACL groups that have been applied on an interface via QoS policy
framework.
• The order option takes precedence over the seq sequence-number.
• If sequence-number is not configured, then rules with the same order value are ordered
according to their configuration order.
• If the sequence-number is configured, then the sequence-number is used as a tie breaker for
rules with the same order.
If the sequence-number is configured, then the sequence-number is used as a tie breaker for rules
with the same order.
