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. The range is 0 to 254 (where 0 is the highest priority
and 254 is the lowest; lower-order numbers have a higher priority). If
you do not use the keyword
order
, 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 is applied to the monitored interface.
NOTE: For more information, refer to the Flow-based Monitoring
section in the Port Monitoring chapter of the
FTOS Configuration
Guide

Command History
Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
Version 8.1.1.0 Introduced on the E-Series ExaScale.
Version 7.4.1.0 Added the
monitor
option.
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.
You cannot include IP, TCP, or UDP (Layer 3) filters in an ACL configured with ARP or Ether-
type (Layer 2) filters. Apply Layer 2 ACLs to interfaces in Layer 2 mode.
NOTE: When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.
