, the ACLs have the lowest order by default
(

fragments
Enter the keyword
fragments
to use ACLs to control packet
fragments.

(OPTIONAL) Enter the keyword
log
to enable the triggering
of ACL log messages.

count
(OPTIONAL) Enter the

keyword then a
value to indicate the maximum number of ACL logs that can
be generated, exceeding which the generation of ACL logs

The threshold range is from 1 to 100.
interval
minutes
(OPTIONAL) Enter the keyword
interval
then the time
period in minutes at which the ACL logs must be generated.
The time interval range is from 1 to 10 minutes.
Defaults
By default 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which the ACL logs are generated is five minutes.

History
Version 9.3(0.0)
Added the support for logging of ACLs on the MXL 10/40GbE
Switch IO Module platform.
Version 8.3.16.1
Introduced on the MXL 10/40GbE Switch IO Module.
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 Networking OS
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
new interval commences from zero. If ACL logging was stopped previously
because the configured threshold is exceeded, it is re-enabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is re-
enabled after the logging interval period elapses. ACL logging is supported for
standard and extended IPv4 ACLs, IPv6 ACLs, and MAC ACLs. You can configure
