Service Manual

log (OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages.
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.
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.
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 Dell Networking OS Configuration Guide .
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.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Added support for flow-based monitoring on the MXL 10/40GbE Switch IO Module
platform.
9.3(0.0) Added support for logging of ACLs on the MXL 10/40GbE Switch IO Module platform.
8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
8.1.1.0 Introduced on the E-Series ExaScale.
7.4.1.0 Added the monitor option.
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.
