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
).
fragments
Enter the keyword
fragments
to use ACLs to control packet
fragments.
log
(OPTIONAL) Enter the keyword
log
to enable the triggering
of ACL log messages.
threshold-in
msgs
count
(OPTIONAL) Enter the
threshold-in-msgs
keyword
followed by a value to indicate the maximum number of ACL
logs that can be generated, exceeding which the generation
of ACL logs is terminated with the
seq
,
permit
, or
deny
commands. The threshold range is from 1 to 100.
interval
minutes
(OPTIONAL) Enter the keyword
interval
followed by the
time period in minutes at which ACL logs must be generated.
The interval range is from 1 to 10 minutes.
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.
Defaults
By default, 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which ACL logs are generated is five minutes. By default,
flow-based monitoring is not enabled.

Usage
Information
The
order
option is relevant in the context of the Policy QoS feature only. For
more information, refer to the “Quality of Service” chapter of the
Dell Operating
System Configuration Guide
.
In the MXL switch, you can configure either count (packets) or count (bytes).
However, for an ACL with multiple rules, you can configure some ACLs with count
(packets) and others as count (bytes) at any given time.
Most ACL rules require one entry in the CAM. However, rules with TCP and UDP
port operators (for example, gt, lt, or range) may require more than one entry. The
range of ports is configured in the CAM based on bit mask boundaries; the space
required depends on exactly what ports are included in the range.
When the configured maximum threshold is exceeded, generation of logs is
stopped. When the interval at which ACL logs are configured to be recorded
expires, the subsequent, fresh interval timer is started and the packet count for that
