Information
The order option is relevant in the context of the Policy QoS feature only. See the “Quality of
Service” chapter of the FTOS Configuration Guide for more information.
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 monitor option is relevant in the context of flow-based monitoring only. See Chapter 30, Port
Monitoring.
Table 6-2 lists the keywords displayed in the CLI help and their corresponding ICMP Message Type
Name.
log (OPTIONAL, E-Series only) Enter the keyword log to have the information kept in
an ACL log file.
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.
