Information
The monitor option is relevant in the context of the flow-based monitoring feature only. See
Chapter 44, 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.
log (OPTIONAL, E-Series only) Enter the keyword log to enter ACL matches in the
log. Supported on Jumbo-enabled line cards only.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL
entry.
Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower order
numbers have a higher priority)
Default: If the order keyword is not used, the ACLs have the lowest order by
default (255).
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic
that you want to monitor and the ACL in which you are creating the rule will be
applied to the monitored interface. For details, see the section “Flow-based
Monitoring” in the Port Monitoring chapter of the FTOS Configuration Guide.
fragments Enter the keyword fragments to use ACLs to control packet fragments.

Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
