Version 7.5.1.0 Introduced on the C-Series.
Version 7.4.1.0 Added support for the non-contiguous mask and added the
monitor option. Deprecated the keyword established.
Version 6.5.10 Expanded to include the optional QoS order priority for the
ACL entry.
Usage
Information
The monitor option is relevant in the context of flow-based monitoring only. For
more information, refer to Port Monitoring.
The order option is relevant in the context of the Policy QoS feature only. The
following applies:
• 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 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.
If you configure the sequence-number, the sequence-number is used as a tie
breaker for rules with the same order.
NOTE: When ACL logging and byte counters are configured simultaneously,
byte counters may display an incorrect value. Configure packet counters with
logging instead.
