Command Line Reference Guide

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.

History
9.4(0.0) Added the support for flow-based monitoring on the MXL
10/40GbE Switch IO Module platforms.
9.3(0.0) Added the support for logging of ACLs on the MXL 10/40GbE
Switch IO Module platforms.
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
Access Control Lists (ACL)
