Information
The monitor option is relevant in the context of the flow-based monitoring feature only. Refer
to the Port Monitoring chapter.
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.
